Scope of Service
SAMCO delivered a turnkey WWTS, providing comprehensive engineering services, including treatability studies, design, on- and off-site fabrication, controls integration, and startup support.
SAMCO engineered a turnkey 100 GPM WWTS to reduce sludge waste generated by plastic and metal drum recycling operations. The design featured a dissolved air flotation (DAF) system in lieu of a clarifier unit to remove suspended solids. The efficient design produced a recycle/reuse rate of up to 70% and reduced chemical feeds and sludge waste, yielding a one-year investment return. To ensure lasting durability, the WWTS design fabricated the reaction tanks unit (RTU) and DAF system from corrosion-resistant SAE 304 stainless steel. The WWTS was also designed to allow for modular scalability to accommodate expansion loads, and was outfitted with programmable logic controls (PLC) to minimize operation and maintenance demands while providing process monitoring for flow, level, pressure, pH, and other factors.
WWTS components included:
