Case Study

Automatic Carwash

Hydrogen Sulfide and Total Suspended Solids Treatment

Problem

Automatic carwash operators have been challenged by city government officials to reduce the hydrogen sulfide in the effluent being released into the city sewer system from the carwash water recovery tanks. The operators also have a need for a product that could purify the recovered water to a point that it could be recycled in the system.

Solution

An Organic Product was applied directly into the recovery tank of an automatic carwash at a rate of 2.5 gal. per 5,000 gal. Within 48 hours, the hydrogen sulfide odors had dissipated. A maintenance program was started adding 1 oz. of product daily to the recovery tank. At the end of the fourth day of treatment, the water in the recovery tank was clear enough to begin recycling it in the system. The recycled water is used in the wash cycle. The cars are coming out of the wash cleaner than before, with no evidence of water spotting which was a major problem when fresh water was used. The carwash operator is now recycling the water from the recovery tank daily. The daily freshwater consumption was reduced by 70-80%.

Conclusion

The performance of the Organic Product exceeded the original expectations. Hydrogen sulfide levels were greatly reduced. The water was sufficiently purified to a point that recycling was possible, and the process reduced the need for fresh water by over 70%.
