LemTec™ Phosphorus Removal System

LET’s Phosphorus Removal System is a proven, effective treatment process that can prevent the damage and devastation this nutrient causes if not removed from the effluent prior to leaving a facility. Because phosphorus is a plant nutrient, it can trigger algal blooms that deplete receiving waters of oxygen, killing aquatic life. In surface waters, algal blooms cause various detrimental impacts to fish and other organisms. Algal blooms also impact the source water quality for drinking water facilities, which can corrode water pipes and leave drinking water too dangerous for consumption. LET’s innovative phosphorus removal technology delivers maximum treatment as simply and efficiently as possible to ensure effluent limits are met and receiving waters are safe.

LET phosphorus removal technologies can be integrated into the larger design of a full LET biological treatment process, or implemented as a stand-alone technology. Our easy-to-operate phosphorus removal system employs a dosing panel and automatic chemical feed system to add liquid co-precipitation chemicals to the wastewater upon its arrival in the technology’s rapid mix zone. Once the rapid mixing of the water has achieved optimum efficacy, the dissolved or suspended contaminants travel as solid floc particles to then settle out of the solution in the flocculation zone at the front end of the settling pond. The settled contaminants can then be removed simply and easily along with the waste biological sludge without requiring extra steps or effort. This LET technology delivers unparalleled removal of phosphorus to ensure our clients’ effluent meets regulatory requirements without the use of mechanical clarification or tertiary filtration.
