The ASA 900 with its stainless steel cabinet, is easy to install, fully automatic and is especially conducive to applications where there is ongoing variation in water quality, such as fluctuations in pH and TDS (Total Dissolved Solids), which typi- cally poses a challenge for other methods of wastewater treatment.
The ASA 900 system comes with two major components, a flocculation mixing station and a filtration station that uses a cascade design to fur- ther clean the water before it is returned for reuse.
The flow path begins in a sludge trap or catch basin where the wash water is captured. A submerged pump sends the water
into the ASA 900’s reaction tank where bentonite clay is automatically injected. The waste stream is then agitated by a stirring mechanism followed by a short dwell period. The flocculant encapsulates the stable emulsified oil droplets and dirt particles and causes them to sink creating sludge.
The sludge is then removed in the filtration station that uses a cascade design to separate the sludge from the water. The water is reused and the sludge is easily removed for proper disposal.
The ASA 900 is ideal for treating wastewater in vehicle cleaning and other high-pressure washing applications where there are heavy loads of oil and grime in the wastewater.
