Water Recycling Systems: Make Better Use of your Water

For car wash businesses, water quality is paramount to their success. Unfortunately, most areas do not naturally have access to higher-quality water. 85% of the US uses hard water (EcoPure) which refers to water with higher mineral content. This article will discuss hard water in depth, the importance of water, and how to use it for the best results in your car washing business.

Water is Vital to Any Car Wash

Water is the lifeblood of your car wash business. The role it plays cannot be understated as it is what will determine the effectiveness of your cleaning capabilities.

Without reliable, high-quality water, running a successful car wash is close to being an impossible task.

Water Cleans, Chemicals Only Help

One may think that the chemicals used in car wash do the cleaning legwork, and while they surely play an important role, the water they are used within is the difference maker.

Water is the universal solvent that carries the chemicals that are used to tackle the intended car wash process.

Understanding the role water plays in your cleaning can help illustrate the importance of ensuring it's clean and ready to be used in car washing.

What is Hard Water?

Understanding water quality starts with learning about hard water. Hard water is water that contains a high amount of dissolved minerals. These minerals commonly include magnesium and calcium, but iron can play a role in it as well.

The lower the amount of minerals and particles in the water, the more 'soft' the water becomes. Ultimately, soft water is what car wash businesses will want to use in their operations.

The presence of these minerals in hard water means it binds to the chemicals used in car washing. This makes your chemicals less effective at cleaning and can lead to significant problems with your car wash business.

It can also cause corrosion and build-up in your equipment, leading to repairs and replacements.

Hard Water Ratings

Hard water is characterized by the particles in water and is measured through Total Dissolved Solids (TDS) using Grains Per Gallon (GPG) or Parts Per Million (PPM). TDS refers to anything that is dissolved in that water, including iron, magnesium or calcium.

The 'hardness' of your water can range and is often referred to as 'Very Hard', 'Hard', 'Medium Hard', and 'Soft'. This will depend on how high the GPG or PPM amounts are, obviously the lower your TDS the better your water quality is.

What Causes Hard Water?

Hard water is created when the water passes through deposits of limestone, chalk or gypsum. As the water passes through these surfaces, minerals are picked up and dissolved in the process.

Effects of Hard Water

The effects of hard water can be very damaging for lots of purposes and industries, and that is no different for car washes.

Car Wash Chemistry

Hard water works to neutralize ingredients found in car wash chemicals, which inhibits them from doing the job they're intended to do. This occurs as the chemicals work to 'clean' the water before they can begin cleaning the vehicle as intended.

It should be noted that some chemicals are designed and formulated to work in hard water environments, but these options will often not deliver the same result you will find when using soft water.

Car Wash Equipment

Hard water can leave build-up and residue in your car wash equipment which can create many problems.

Blockages are the most common issue that equipment will face as the mineral deposits stop water from going through easily. Blockages can lead to worse issues such as breaks or leaks that will need to be repaired or replaced.

Water Spots

Hard water can also impact how the cars you clean look after they dry. Hard water once dried and evaporated can leave visible water spots that are mineral particles that remain on the surface.

How to Know if you have Hard Water?

There are many different ways to tell if you have hard water ranging from visual clues, location, and having your water tested.

Visual Clues

When hard water dries (and evaporates), it often leaves a white residue as the calcium and magnesium particles remain on the surface. You may see this residue on vehicles you clean, piping, faucets, or other equipment that comes into contact with water.

Location

Hard water often varies by location, some areas are much more susceptible to hard water than other areas. The hardness level can differ by location as well.

Using a hard water map can show if you're typically in a location that faces hard water and how hard that water may be.

Water Testing

In water testing, a water sample is collected, and it is read for its GPG or PPM rating to see where it falls on the hard water scale.

As this is measuring the particles in your water, this is by far the most accurate method in determining if you have hard water or not.

What is Soft Water?

Soft water is essentially the opposite of hard water. It has a low amount of dissolved minerals, usually below 1 GPG but can be as high as 3.5 GPG.

This type of water is desired as it does not contain the number of particles that will bind to your car wash chemicals and leave those water spots after the vehicle has dried.

Using soft water will help you get more out of your car wash chemicals and make sure that surfaces are cleaned effectively.

Solutions to Hard Water

Car washes are highly encouraged to soften their water if they do have hard water. This can be done through two main methods:

Water Softeners

Water softeners work by pulling out the calcium and magnesium particles and replacing them with sodium and are typically the affordable option as far as tackling hard water goes.

In a softener system, hard water passes through a process of ion exchange resins, a bypass, and a regeneration system where the ion exchange can take place.

Salt replaces magnesium and calcium as it is much less reactive with car wash chemicals, which solves the problem at hand.

However, since the particle amounts may not change much, the PPM of water after going through a water softener may be similar to what it was before. And while that will mean better chemical applications, you may still have an issue with water spots as the sodium can dry on the surface of a vehicle as the water evaporates.

Reverse Osmosis (RO) System

Reverse osmosis systems are the recommended option for hard water challenges for any car wash. This is the case as they do an exceptional job at softening water and giving you the ability to wash cars that will look clean, but also dry clear.

An RO system works by passing hard water through a semi-permeable membrane that filters out the calcium and magnesium particles, leaving behind soft water with lower levels of PPM than when it first entered the system.

RO systems are the only way to filter out the minerals from water, instead of replacing them like in a softener system.

This is a more expensive option, but it will ensure full functionality of your car wash chemicals, give you that 'spot-free rinse' (no water spots), and not interfere with your equipment.

Understanding Water Quality in Car Washes

Car wash owners should be aware of the role water quality plays in getting fantastic cleaning results with chemicals. It's crucial to have a good understanding of water hardness, total dissolved solids (TDS), and pH levels. These factors affect overall car wash performance and water supply quality. Let's take a closer look at these components and how to manage them.

Water Hardness and Total Dissolved Solids (TDS)

Water hardness is determined by its calcium and magnesium content, measured in grains per gallon (GPG). Hard water poses challenges for car washes, as it hampers the performance of chemicals and leaves spots on vehicle surfaces. A reverse osmosis process can filter and reduce TDS, allowing for a spot-free rinse. The various levels of TDS in water sources – from spot-free (0-20 PPM) to poor quality (600 PPM+) – can significantly impact car wash processes, requiring different treatments and techniques for optimal results.

Managing pH Levels

The pH of a car wash's water source also plays a crucial role in chemical effectiveness. Ideally, water should have a neutral pH (7), as untreated source water is often on the alkaline side, limiting the effectiveness of low-pH products. If you encounter issues balancing pH levels, using a pH test strip can help you confirm water pH and adjust accordingly.

Reclaim Water Systems in Car Washes

Reusing water is a growing trend in the car wash industry, aimed at conserving water resources and minimizing environmental impact. Reclaim water systems treat and recycle the water collected from car wash processes for reuse. However, treatment methods and filtration processes can leave some trace elements in the water that may have adverse effects on detergent and drying chemicals. Let's discuss the impact of reclaim water on water quality and how to optimize its use in car wash applications.

Effect of Reclaim Water on Water Quality

Reclaim water systems utilize various treatment methods, such as bio-reactive bacteria, which break down chemicals, and ozone to purify and remove particulates. However, they can't entirely remove all solubilized chemicals from the water. The remaining trace elements, measured as TDS, can influence the effectiveness of detergents and drying products, causing unexpected reactions when compared to using a freshwater source. To mitigate these issues, car wash operators are advised to use reclaimed water only for rinsing applications without chemical introduction.

Optimizing Reclaim Water in Car Washes

To optimize the use of reclaimed water, car wash owners should regularly monitor TDS and pH levels to maintain chemical performance and water quality. Combining water reclamation systems with thorough filtration and treatment methods will ensure that the recycled water is as high quality as possible. Additionally, proper maintenance and regular testing of water softeners are crucial for consistent results and success in the car wash process.

With decades of experience supporting car washes, we're not strangers when it comes to water and its challenges, especially hard water related.

Water is one of the most important factors for any wash business and you will want to be sure to tackle your water situation in the best manner possible.

Whether that means choosing between a water softener or RO system, finding the right car wash chemistry, or even just picking a new wash location, we're here to help you make the right decision for you and your business.

An important factor for any type of car wash business is equipment. Whether it's big commercial machinery, a pressure washer, or even just drying towels, equipment is what helps us clean and dry cars.

But there is a lot of equipment on the market, most of which is not necessary for every car wash. However, as a car wash business owner, how can you decide on which equipment you need, or which you don't need.

That is exactly why we're here to walk you through car wash equipment, with the goal of leaving you more confident in deciding what equipment you should be purchasing for your car wash.

Equipment For a Car Wash: What Every Wash Can Use

When you first think about car wash equipment, you may think of conveyor belts, huge dryers, and moving water pressures systems that automatic car washes use. While that is important, it does not stop there, there are other less flashy types of equipment that should be used in a car wash business.

Reverse Osmosis System or Water Softener

This type of system is used to remove impurities from water before it even enters the car wash. This ensures that your car wash equipment doesn't get gunked up with minerals and other particles that can cause damage. Water with lots of minerals, or hard water, can even interfere with the car wash process itself, leaving a poor result. We have a blog detailing all the effects about hard water. In order to get a spot free rinse a reverse osmosis system is required.

Water Reclaim System

A water reclaim system is used to recycle water from the car wash. This helps to cut down on water usage, as well as sewage fees, because less water is being sent down the drain.

These systems turn dirty, used water, into clean water that can be used again. ClearTech specializes in water recycling and you can check them out if you're interested.

Types of car wash equipment for an automatic wash

Brushes

Some automatic car washes use brushes that will rotate and scrub off dirt, grime, and marks off of vehicles. These brushes are large, and vary in abrasive level. Automatic washes won't always use brushes, but it's a common method for those that do.

Conveyors

A conveyor carries the vehicle through the car wash. Not all automatic washes use a conveyor system.

If they do use one, it is typically for a tunnel car wash, where the vehicle is carried through a long tunnel. With each section being a different stage of the car wash that cleans all those painted surfaces, windows, and wheels of a car.

Dryers

After a vehicle is washed, it needs to be dried off before the residual water evaporates and leaves water marks. Automatic car washes typically have very large and strong dryers that will quickly and efficiently dry off the vehicle.

High Pressure Water Systems

Automatic car washes have high pressure washers that do an excellent job at quickly and efficiently washing and rinsing vehicles.

These are especially important in touchless car washes, where no friction is used, and will need an precise amount of water pressure to leave a spot free rinse!

Wheel Cleaners

Some automatic car washes have wheel cleaners. These are special machines that will quickly and easily clean the wheels of a vehicle. Situated before the dryers, the wheel cleaner cleans off any residual water and brake dust that may be on the wheels.

Chemical applicators

Automatic car washes typically have chemical applicators that will apply presoaks, soaps, detergents, waxes, and other chemicals to the vehicle during the wash process. Often these applicators can be embedded within arches for additional show.

Types of Equipment for a Self Service Car Wash

Self Serve Systems

Self serve washes need much less individual equipment to operate. These types of car washes commonly have an all-in-one system that is multi purpose and has all the features that customers need to wash their vehicles.

These systems can apply presoaks, triple foam detergents, wax, tire cleaner, drying agents and more. This way, you can save room and money, while keeping everything in one area for people to use in washing their cars. They typically have a spray gun or brush that customers use to apply the solutions themselves.

Extras

These help the job, like a tire scrubbing brush, or microfiber towels or microfiber cloths. These are pieces that can make the process quicker or easier, but typically aren't necessary to get the job done.

Types of Equipment for a Full Service Car Wash

All in One Systems

Since full service washes also wash cars by hand, it would make sense that they also use a similar type of car wash system as a self service car wash. The employees would use a system that can apply presoaks, soap, wax, and other chemicals to the vehicles, and clean them for customers.

Extras

These are small extras such as drying towels, microfiber cloths, and other related tools that help the employees clean and dry cars effectively.

Central Vacuum Systems

A central vacuum system is a very important piece of equipment for full service car washes. This is because it allows the employees to quickly and easily clean the inside of customer's vehicles without having to lug around a heavy and inconvenient vacuum cleaner. Central vacuum systems may be available at automatic and self serve washes but since those business' are catered towards cleaning only the exterior of vehicles, it is more of a priority for full service car washes.

Types of Equipment for a Truck Wash

Since trucks are so large in size and sometimes have a challenging shape to clean, there are specially designed equipment to tackle their wash.

These systems are usually sold together in two varieties:

Drive Through Truck Wash

Almost like an in bay automatic wash, but with a twist of tunnel washes, trucks drive through a wash bay where stages of equipment will clean the truck as it drives through.

Roll Over Truck Wash

In this system, trucks go into a wash bay and stop while equipment goes around the truck and washes it. The advantage of this type is that it can clean more effectively for trucks with unique shapes.

How to choose the right car wash equipment for your business

When starting a car wash business, one of the most important decisions you will make is choosing the right car wash equipment.

There are many factors to consider, including the type of vehicle you will be washing, the climate in your area, and your budget. For example, if you live in an area with harsh winters, you will need equipment that can withstand freezing temperatures.

Alternatively, if you plan to wash high-end vehicles, you will need equipment that can provide a gentle clean.

Once you have considered all of these factors, you can begin to narrow down your options and choose the car wash equipment that is right for your business. With the right equipment, you will be able to provide an excellent wash for your customers and build a successful car wash business.

Maintenance and cleaning tips for car wash equipment

As anyone who has ever operated a car wash knows, keeping the equipment clean and well-maintained is essential for proper functioning. Not only does this help to ensure a high level of customer satisfaction, but it can also extend the life of the equipment and prevent costly repairs.

Here are some tips for keeping your car wash equipment in top condition:

• Inspect the equipment regularly for any signs of wear or damage.
• Make sure all moving parts are properly lubricated.
• Keep the exterior of the equipment clean and free of debris.
• Periodically check hoses and other plumbing components for leaks.

By following these simple maintenance tips, whether you have one location or many. you can keep your car wash equipment running smoothly for years to come.

How much should you pay for car wash equipment?

The exact amount you pay for your car wash equipment will dependent on any number amount of factors. But whether you buy the cheapest equipment you can find, or the most state of the art, can impact your car wash business in many ways.

Car wash equipment is expensive and you will need to account for it when deciding to buy or replace your business' equipment. But buying the cheapest equipment on the market can leave you with lackluster results, on top of potentially breaking down sooner.

On the other hand, buying the latest and greatest thing can leave your business in a such a large financial hole, you may not be able to allocate the funds necessary for all the other aspects of your car wash business, such as staffing, training, chemical selection, or marketing.

Be sure to do your research on the specific pieces of equipment you are looking at. We highly recommend Washworld Inc.'s equipment as they are some of the best pieces you can buy but still for a realistic price. You can view their featured products.
