LemTec™ Biological Treatment Process s an effective, reliable and affordable solution for pond-based municipal and industrial wastewater treatment facilities. At a fraction of the cost of other traditional systems, the LemTec™ BTP provides accelerated treatment of wastewater in simple, operator-friendly ponds that require minimal system operation and maintenance. With a reduced footprint and an operation that is virtually odor-free, the LemTec™ process is the highest performance pond-based package in the world. The LemTec™ Biological Treatment Process is unmatched in its ability to meet stringent effluent limits that other traditional pond-based systems can't reach.  Utilizing a series of aerobic treatment cells followed by an anaerobic settling zone and polishing reactor, the LemTec™ process is capable of achieving year-round effluent limits as low as 10 mg/l BOD, 10 mg/l TSS and 2 mg/l NH₃-N for typical municipal or pre-treated industrial wastewater.
