Water Inlet Channel (well)
Sewage grinders can pulverize suspended solids and floating debris in water channels into particles measuring 6mm to 12mm.
Sewage Lift Station Projects
Sewage grinders can be installed at integrated lift pump station to reduce the size of solid waste, protect pumps, and ensure efficient wastewater transport.
Municipal Sewage Systems
Sewage grinders are used in municipal sewage pipeline systems to reduce the volume of solid waste, prevent pipe blockages, and protect pumps and other equipment during wastewater treatment.
Industrial / Commercial / Residential Areas
Industrial, commercial, and residential areas all generate various types of solid waste. Sewage grinders can help manage this waste and maintain the smooth operation of the sewer system.
