Examples of Equivalent Processes: PFRP and PSRP
Equivalent Processes: PFRP and PSRP
-
Fact Sheet: Recessed-Plate Filter Press
Recessed-plate filter presses can be used to dewater most biosolids generated at municipal wastewater treatment plants.
-
Fact Sheet: Land Application of Biosolids
Recycling biosolids through land application serves several purposes. It improves soil properties, such as texture and water holding capacity, which make conditions more favorable for root growth and increases the drought tolerance of vegetation.
-
Fact Sheet: In-Vessel Composting of Biosolids
In-vessel composting occurs within a contained vessel, enabling the operator to maintain closer control over the process in comparison with other
composting methods. -
Fact Sheet: Alkaline Stabilization of Biosolids
Stabilization of biosolids helps to minimize the potential for odor generation, destroys pathogens (disease causing organisms), and reduces the material’s vector attraction potential.
-
Fact Sheet: Belt Filter Press
Belt filter presses can be used to dewater most biosolids generated at municipal wastewater treatment plants and are a common type of mechanical dewatering equipment.
-
Fact Sheet: Centrifuge Thickening and Dewatering
Dewatering removes water and produces a drier material referred to as “cake” which varies in consistency.
-
Fact Sheet: Multi-Stage Anaerobic Digestion
Multi-stage anaerobic digestion can achieve superior performance relative to single-stage conventional digestion for most wastewater solids
and for all loading rates.
