Water Treatment Systems

Wastewater Treatment (WTS) Systems
Being able to treat and sewer water separated from grease trap waste makes an enormous impact on disposal costs. Sewering water at your facility also reduces wasted driver time and truck miles. Building a wastewater treatment system from scratch can be a daunting task, dealing with multiple vendors, taking up a lot of floor space, and carrying a huge price tag. With the WTS system, we started from the ground up with a complete skid-mounted system that is designed specifically for treating wastewater from FOG recovery. We have included features that allow for additional grease recovery, reduce treatment chemical consumption and improve finished water quality. We have also stripped out unnecessary equipment to keep cost low.

How it Works
Raw wastewater enters the WTS skid and is screened to remove trash and debris. The feed then enters an enhanced catchall clarifier section where FOG and floating solids are allowed to separate prior to chemical treatment. The FOG and solids recovered in the catchall are routed back to the GWX system for recovery. The partially treated water is then put through a pH adjustment cell where sodium hydroxide or lime slurry are added to bring the pH up to allowable range for discharge. The neutralized water then flows through a flocculation cell where polymer is added to flocculate the residual grease and solids. The flocculated feed then enters the dissolved air flotation cell where it is mixed with air-saturated water to float the remaining FOG and solids. The clarified wastewater exits the DAF clarifier cell to the plant sewer connection. The DAF float from the DAF cell is sent to storage or dewatering.
