Wastewater treatment plants can be built for small-scale applications

Innovative Treatment Products redesigns its process control system to handle a wide range of treatment throughput

Wastewater treatment plants can be built for small scale applications nav

For most people, treatment of wastewater from homes and businesses is one of those it-just-happens things taken care of by local governments. But any facility too isolated to connect to a larger sewer system—such as a school, office or retailer—will have to supply its own treatment for obvious practical reasons and to avoid a variety of fines from environmental agencies.These isolated locations often have too much water to treat using a septic tank, so they must provide their own wastewater treatment plant (WWTP), usually a miniature version of city-scale counterparts. The main operational problem these small-scale WWTPs face is flow variability. A small-scale WWTP…
