LemTec™ Covered Lagoon Activated Sludge System (CLASS) provides accelerated treatment of wastewater in simple, operator-friendly ponds that require minimal system operation and maintenance.  By utilizing the patented LemTec^TM Modular Insulated Cover, process characteristics are enhanced through heat retention within the water column.  This warmer climate provides conditions conducive to the reduction of biochemical oxygen demand and total suspended solids in the aerated cell of the CLASS process. Therefore, the LemTec™ CLASS is unmatched in its ability to meet stringent effluent limits that other traditional pond-based systems simply can’t achieve. The LemTec™  CLASS is an effective and affordable solution for many municipal and industrial wastewater treatment facilities. With more than a 50% reduction in footprint for typical aerated lagoons and with a process that is reliable and virtually odor-free, the LemTec™ CLASS is the highest performance pond-based package in the world.
