Water Treatment, Reverse Osmosis & Water Softeners

From the high efficiency Sweetwater Reclaim Water Treatment System to the Reverse Osmosis Spot-Free Rinse to the Water Softeners, Coleman Hanna offers all the latest advances in water treatment and reprocessing. Saving water is crucial in today's world. Modern car washes require water reclaim or recycling systems to decrease the amount of fresh water usage. Spot-Free Reverse Osmosis Systems are vital to ensure a spot-free final rinse to the vehicle. Water Softeners have always been essential to remove hardness in the water and prepare it for car washing.

Sweetwater Water Treatment (Reclaim) System

Finally a simple robust reclaim system that won’t break the bank. Save up to 120 gallons per minute, with the dual element system, with 32 internal hydrocyclones to spin the dirt right out of your wash water. Clear Lexan bowls let you see the removed particulate. Graphic PLC monitors the system, providing water on demand and performs the self cleaning function. When not needed the VFD controlled high efficiency motor slows to recirculation mode. Optional
ozone removes color and odor and the optional bio control gets rid of surfactants, keeping your storage tank water fresh. Slim design fits easily into most equipment rooms or wash bays.

General Notes:

  1. Reclaim should sit two to four inches from equipment room wall.
  2. Do not stub-up pipes tight together or against wall.
  3. Leave room for plumbing to unit. We recommend 16”.
  4. Use SCH 80 cleaner and gray glue for suction lines. Cleaner and glue on all others.
  5. Use of 45 fittings instead of elbows on suction and discharge lines will improve performance.

Sweetwater Spot Free Rinse System

Spot-Free Reverse Osmosis System



Coleman Hanna Carwash Systems has designed, engineered and manufactured spot-free rinse systems utilizing reverse osmosis (RO) technology since the 1980’s. Having experience during five decades, Coleman Hanna is clearly a leader and innovator in this field.

Spot-free rinse is a very important part of the vehicle wash process. Water naturally contains Total Dissolved Solids (TDS), when water evaporates it leaves behind the solids or powders on the vehicle and they become spots.

What would have been a clean and shiny vehicle now is not and actually can lead to a displeased customer. This dissatisfied customer gives negative reviews about your business which prevents potential customers from visiting your car wash.

It is much easier and profitable to remove the spots from the final rinse water. Reverse osmosis is a mechanical process where fresh water, without chlorine, is pumped through membranes, which remove the TDS from the water. This produces clean water that allows vehicles to be rinsed and be spot-free. As the membranes collect the TDS they require a flushing process to keep them clean and functioning properly. This is called the reject water and can be designed to be recycled back into the system.

At Coleman Hanna we have learned that the most efficient way to size systems is to manufacture systems up to 6,000 GPD and then duplicate multiple systems into one to meet the daily requirement of the system. Water storage capacity is also a factor as water usage is usually in 10 hours per day or less while production is ongoing 24 hours per day

Reverse Osmosis Process


Engineering and Maintenance -

Engineered with the best available components on the market, the Sweetwater Spot- Free Rinse System will deliver low pressure pure water to the car wash bay. The Sweetwater Spot-Free Rinse System can be installed “on-board” for newly purchased wash systems or separately for existing car washes. Installation can usually be done in a day, without downtime. Regular maintenance can be done by the operator simply by changing prefilters and checking water for purity.

More Customers, More Profits -

By offering RO with your car wash, you will not only gain satisfied customers, but you can also increase your bay income. RO can produce up to 12% of your bay income. This is the most cost effective product in a bay giving you a high rate of return on
