Lamellar High Performance Settler

Precipitation and flocculation have a long history in water treatment. First systems were used for wastewater treatment in 1872 in Birmingham. Since, then, the phenomena have been investigated and the treatment systems improved accordingly.

The LHPS is certainly at the peak of this development. Here, all learnings have been implemented and every single reaction step optimized in terms of kinetics, mixing needs and reaction performance. Consequently, a unique system dividing mixing of chemicals, coagulation, flocculation, sedimentation, particle removal, and sludge thickening has been created by BHU engineers.

Each system is taylored to the needs of the respective task. Depending on the dosage of chemicals applied, reaction temperature, sludge formation, each system has its own DNA. All processes that include precipitation and flocculation can be implemented: Coagulation/flocculation, softening or decarbonisation both for water supply and wastewater treatment.
