LAMELLA CLARIFIER PDF

This type of clarifier uses gravity in conjunction with the projected settling area of the degree angle plastic parallel plates to settle solids from the pre-treated liquid flow. This treated liquid flows first to the flocculation tank where a polymer is added to promote floc growth, then down to the bottom of the clarifier and up through the plate pack s while the solids settle out to the bottom sludge cone or cones — depending upon the size. The solids are intermittently taken from the bottom cone tank for a further settling of the solids and then, finally to a filter press for final dewatering. They are constructed of carbon steel with coal tar epoxy lining on the inside, and epoxy coating on the exterior.

The solids are intermittently taken from the bottom cone tank for a further settling of the solids and then, finally to a filter press for final dewatering. They are constructed of carbon steel with coal tar epoxy lining on the inside, and epoxy coating on the exterior. Also available in stainless steel and polypropylene. The internal plate packs are set at 60 degrees for optimum settling and are constructed of a coal tar epoxy-coated steel shell with plastic plates.

This sludge blow-down system is designed to monitor the time the Clarifier is in use, i. After the predetermined time has elapsed, the controller will automatically open the discharge valve and activate the discharge pump to the sludge thickening Tank, and then automatically turn off the pump and close the valve. System includes: Sludge Valve, air valve and control panel with timers and cast iron diaphragm pump. System complete with controls, valve and diaphragm pump. Air Operated Pinch Valve.

Lamella Plate Clarifier

Lamella clarifiers are considered to be one of the best options for pre-treatment ahead of membrane filters. Further lamella clarifiers are able to maintain the required water quality to the membrane without the use of chemicals. This is a cost saving measure both in purchasing chemicals and limiting damage to the membrane, as membranes do not work well with the large particles contained in flocculants and coagulants. Lamella clarifiers are also used in the municipal wastewater treatment processes.
