The important first step is required to agglomerate the suspended sludge solids into \u00ab flocs \u00bb and thus provide an initial separation of sludge solids from the liquid. This stage consistsin injecting polymer in the sludge. Normally, the floculant is injected upstream the sludge pump to benefit from a progressive mixing by the eccentric screw of the pump. Conditioning is also designed to build a \u00ab structure \u00bb into the sludge floc so that they can withstand gradually increasing pressure and shearing action. In general, a BFP cannot function without polymer conditioning.<br \/>\nThen floculated sludge spreads over the filtering belt using a distribution tube in Upvc : free water created during sludge conditioning drains through the belt pores. The importance of proper sludge conditioning in BFP dewatering can be readily observed at this point. Without conditioning, liquid sludge will simply pond in the gravity drainage section or run out the edges of the belt. When the two filtering belts converge, pressing and shearing stage begin. The first roller has an important diameter (\u2205400) in order to<br \/>\nget a progressive pressing. Pressing and shearing operate all along the belt length thanks to 9 rollers with a diameter of 200, which enable to get a progressive pressing of the sludge.Therefore sludge dewatering is maximal and the capture rate is optimal. After the last pressing stage, the dewatered sludge scraped from the filtering belts, and then evacuated on a mesh conveyor or other system. To enable the filtering belts to keep their filtration capacity, they are washed continuously on the travel back to the thickening zone.<\/p>\n<p dir=\"ltr\"><strong>Sludge thickening &#8211; Gravity Belt Thickeners<\/strong><\/p>\n<p dir=\"ltr\"><strong>OMEGA SD range<\/strong><\/p>\n<p dir=\"ltr\">Designed for continuous mechanical thickening of municipal or industrial sludge<\/p>\n<ul dir=\"ltr\">\n<li>Continuous thickening<\/li>\n<li>Belt width\u00a0: from 0,50 to 2,50 m<\/li>\n<li>Filtration\u00a0length : 2 m<\/li>\n<li>Sludge flowrate: up to 40 m3\/h<\/li>\n<li>Very clean operation<\/li>\n<li>Easy maintenance and supervision<\/li>\n<li>Low energy consumption and operating costs<\/li>\n<li>Material\u00a0: stainless steel 304L, 316L or other<\/li>\n<\/ul>\n<p dir=\"ltr\"><strong>OMEGA MD range<\/strong><\/p>\n<p dir=\"ltr\">Designed for continuous mechanical thickening of municipal or industrial sludge<\/p>\n<ul dir=\"ltr\">\n<li>Continuous thickening<\/li>\n<li>Belt width\u00a0: from 1 to 3 m<\/li>\n<li>Filtration\u00a0length : 3 m<\/li>\n<li>Sludge flowrate : up to 80 m3\/h<\/li>\n<li>Very clean operation<\/li>\n<li>Easy maintenance and supervision<\/li>\n<li>Low energy consumption and operating costs<\/li>\n<li>Material\u00a0: stainless steel 304L, 316L or other<\/li>\n<\/ul>\n<p dir=\"ltr\"><strong>OMEGA LD range<\/strong><\/p>\n<p dir=\"ltr\">Designed for continuous mechanical thickening of municipal or industrial sludge<\/p>\n<ul dir=\"ltr\">\n<li>Continuous thickening<\/li>\n<li>Belt width\u00a0: from 1 to 3 m<\/li>\n<li>Filtration\u00a0length : 4m<\/li>\n<li>Sludge flowrate: up to 100 m3\/h<\/li>\n<li>Very clean operation<\/li>\n<li>Easy maintenance and supervision<\/li>\n<li>Low energy consumption and operating costs<\/li>\n<li>Material\u00a0: stainless steel 304L, 316L or other<\/li>\n<\/ul>\n<p dir=\"ltr\"><strong>OMEGA THC range<\/strong><\/p>\n<p dir=\"ltr\">Designed for continuous mechanical thickening of municipal or industrial sludge.
