Biological Treatment

Smith & Loveless Ltd. offers a complete range of aerobic, biological wastewater treatment systems to meet the varied needs of industry, commercial facilities, municipalities, and private development. Our broad system list ranges from innovative membrane bioreactors, patented sludge busting biological processes, and complete extended aeration plants. Our pre-engineered systems come in factory-built and field-erected configurations, handling capacities from 1,000 gallons per day to 5 million gallons per day. All systems are tailored to meet design requirements for centralised and decentralised, off-grid applications.


S&L proudly offers TITAN MBR™, our latest pre-engineered wastewater treatment system for municipal, onsite and industrial applications. The innovative TITAN MBR™ combines the wastewater treatment engineering expertise of S&L with submerged, flat-plate membrane technology. The combination yields a dynamic membrane biological reactor (MBR): a system that provides end-users with high-quality treatment performance, minimal operational requirements, and a robust design that will stand the test of time.

The patented FAST® Process stands for “Fixed Activated Sludge Treatment,” a fixed-film, aerobic treatment system designed for tackling variable load and flow conditions. Proven in thousands of installations worldwide, FAST® consists of tankage packed with completely submerged media. The FAST® media creates a high surface area-to-volume ratio, which, combined with internal settling zones, maintains constant bacterial growth during low-flow and peak usage. Read More >
