The quantity of primary and surplus sludge is reduced as a result of sludge thickening procedures and disposal costs are therefore lowered Special stirring and scraping mechanisms reduce the water content of the sludge in the sludge thickening tank and enable a continuous removal of still pumpable free-flowing sludge into a collection hopper

Gravity sludge thickener PACIFIC

Gravity sludge thickener PACIFIC is used for the solid concentration of decanted solids and clarification of liquids It primarily consists in a tank (generally concrete) of circular plant with troco-conical bottom sloping into this tank On this tank used to assemble mechanical equipment to the sludge collecting The raw water are powered by the upper part to the power cylinder situated in

Belt Filter Press / Thickener (for Sludge Handling System) The belt filter press is a kind of thickener for sludge handling system It is a sludge dehydrator that transforms the processed sludge from low consistency to high consistency Sludge is gradually dehydrated in different areas by means of gravity dewatering wedge dewatering swing dewatering cut dewatering and other methods Finally

WRA evaluated alternative methods of sludge thickening prepared designs and contract documents and provided engineering services during construction for a new gravity belt thickener facility one of the largest in the United States The goal of the project was to provide a facility capable of producing a thickened sludge solids content of 8 - 10% to enable enhanced stabilization in the egg

The design of the new thickener at Chiquita is located on the edge of the existing gravity thickener This allows the thickener output to be conveyed from the thickener to the storage tank by gravity The thickened sludge will drop into a pipe that will convey the sludge into the old gravity thickener (storage tank) which is at a lower elevation

Gravity Sludge Thickeners

Gravity thickeners are designed for most applications involving sludge thickening Solids are thickened by gravity then collected at the bottom of the basin and raked to a collection sump for removal The clarified effluent exits over the weir plates and out of the basin

Gravity thickener designs usually include circular tanks 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter The dimensions are based on prediction of settling due to gravity alone To assist solids transport gravity thickener bottoms are constructed with a floor slope between 1 6 and 1 3 Rectangular units have been used as gravity

Sludge Rake Description The sludge blanket is slowly moved to a center sludge sump by a sludge rake mechanism The gentle rake action promotes the sludge thickening process by gently pushing the sludge to the center sump thereby forming pathways for the solids to compact and water to escape One 3 flanged fitting on the sludge sump

Dewa Gravity Belt Thickener BTN The DEWA BTN Gravity Belt Thickener is a fully enclosed system designed to increase the dry solid concentration of the feed sludge considerably Enclosed construction enables odor containment within the unit simplifying odor extraction by the ventilation pipe located on

Thickening is the first step for reducing the sludge volume by removal of free sludge water Thin sludge is concentrated to thick sludge Thick sludge has a higher viscosity but must still be pumpable Sludge settles in gravity thickeners and is compressed by the weight of its own solids

Gravity Thickeners for Activated Sludge

The first known gravity thickener for activated sludge designated as a sludge thickener was placed in opera tion in Los Angeles The 10-ft (3 05 m) diam tank was part of the facili ties used to explore the conversion of raw wastewater to drinking water dur ing the period from 1930 to 1934 Goudey reporting on the results obtained with this thickener stated The sludge is easily concentrated

Products Sludge Thickening Liqui-Fuge RDT Rotary Drum Thickener The Liqui-Fuge RDT Rotary Drum Thickener is designed for volume reduction of primary waste activated or digested sludge and ideal for reducing hauling costs or increasing digester capacity for municipal or industrial sewage treatment facilities

The basic operation of the gravity thickener is described in this lesson focusing on the theory of operation components found in a typical thickener and the parameters which must be understood in optimizing the opeation of the thickener Attention is given to mathematics concepts which are used in controlling hydraulic loading detention time and material balance

Using the sludge thickening filter press reduces the middle convergence costs of thickening and filtrating operations which need the pump buffer pump pool and steel tube to be connected Therefore using the sludge thickening filter press greatly reduces the costs in the auxiliary devices equipment labor management and energy consumptions

The Gravity Belt Thickener OMEGA THC can be used √ As a final step to increase the sludge DS concentration to 6–8% Therefore replacing conventional gravity static thickener flotation system √ As a pre‐dewatering stage when combined in‐line with a Belt Filter Press to
