Grit removal, processing and handling is another area where wastewater treatment plants can improve savings. If allowed to enter the plant, grit will clog systems – reducing efficiency and cause abrasion damage which can prematurely wear down pumps and valves. This all adds to operations and maintenance overhead. Choosing the correct grit trap, classifier and washer can considerably cut down on costs.
Sediment, composed of a mixture of organic sludge, solid matter of various types and mineral grit, builds up in sewer systems and grit chambers. The KUHN KSW-S/RW Grit Washer and Separating machine separates sediment into organic solid matter and mineral grit parts, enabling separate disposal.
Features
The advanced functionality of the KUHN KSW-S/RW Grit Washer and Separating Machine facilitates a continuous, systematic separation of the material flow into heavy mineral components and lighter, predominantly organic matter. Features include:
Organic content reduction to ≤ 3% loss on ignition
Filtration efficiency of 95% with particle size 0.2 mm
Concentration of dry substance for the discharged grit >90%
Very large tank volume for filtration efficiency of fine and super-fine grits
Adjustable positioning of the inlets and outlets, including the discharge screw
Vortex mixer machine with a special bearing unit for extra supports
Three leg supports for free standing sediment tank
No lower bearing for the grit discharge screw
Standalone separation containers via three heavy-duty load brackets
Intuitive and spacious instrument panel
Low operating costs
Easy to maintain (all parts are removable and easy to access).
