Merit Filter Corporation Sludge Thickening Device™
A Practical Solution for Sludge Thickening and Removal of Excess Liquid
MERIT FILTER CORPORATION SLUDGE THICKENING DEVICE™ is the most practical method of thickening virtually all biological and industrial waste sludges. The SLUDGE THICKENING DEVICE™ has no direct power requirements. Thickening can be accomplished, in most cases, without the use of coagulants or inorganic additives, such as alum.
The MERIT FILTER CORPORATION SLUDGE THICKENING DEVICE™ works by taking advantage of the laws of nature and physics. Dilute sludges, when not being aerated, or stirred, will settle. This settling will result in separate layers of sludge and supernatant. This separation, or stratification, will result in the heavier layers of sludge sinking to the bottom of your tank, while the lighter layers, or supernatant, will rise to the top.
The MERIT FILTER CORPORATION SLUDGE THICKENING DEVICE™ enables the plant operator to easily remove the layer, or layers, of supernatant while leaving a thickened sludge behind. The removal of the supernatant is accomplished by the Sludge Thickening Devices ability to allow draw-off of the supernatant, by providing an area of reduced head, in the device’s well, while retaining the sludge on the outside of the device.
The MERIT FILTER CORPORATION SLUDGE THICKENING DEVICE™ can be installed in existing sludge holding tanks, aeration basins, or incorporated into new sludge holding/aeration basins.
The SLUDGE THICKENING DEVICE™ can thicken digested sludge one day and primary sludge the next and a chemically treated sludge another.
The MERIT FILTER CORPORATION SLUDGE THICKENING DEVICE™ is durable and practically maintenance free. It is constructed entirely of Type 304 stainless steel and has no moving parts. It is typically operated without the use of expensive chemicals and requires no direct supervision.
