Sludge Dewatering. As the liquid flows through the pond, the g force causes the solids to settle out of the liquid and to sediment against the bowl wall. This causes a blanket of solids to build up against the bowl wall. The solids that build up against the bowl wall are pushed to the opposite end of the liquid discharge by the screw conveyor,
Sludge thickening occurs within the blanket, which is generally 12 to 24 inches deep. The uppermost sludge layer will form a pudding like consistency. As the skimmer travels around the tank, the top layer of the solids is pushed up the sludge collection box.
The Triveni Traveling Bride Sludge Collector is used for the removal of settled solids and / or floating material from Clarifiers in Water and Waste Treatment applications. The Traveling Bridge Sludge Collectors are ideally suited for use in a corrosive environment, where sludges are relatively
Circular Thickeners provide a crucial treatment step between upstream process screens, clarifiers, and separators and downstream dewatering and sludge conditioning processes. A well designed thickener provides storage and equalization, reduces the volume of

The mechanism consists essentially of a deep sludge scraper blade carried by a bridge which spans the width of the tank. The bridge is mounted on 4 flanged wheels which ride on rails and travel the length of the basin. Where floatable solids are present, a skimmer blade can also be furnished.

Sludge Thickening vs. Dewatering. Both are methods of solids concentration and volume reduction. Only the degree of volume reduction is different. Generally thickeners concentrate sludge at lower than 15% concentration, the dewatering units concentrate the sludge to higher than 15% concentration .
Sludge Scraper . Our standard designs allow for large systems to be shipped and assembled in shortened timeframes. A number of sizes and configurations are predesigned to efficiently meet the majority of applications. Customizable options ensure that the customer's specification is met.
The Ovivo sludge thickener is designed to continuously produce as thick a sludge as possible from streams of sludge previously formed and collected in separate settling basins. Included with the thickener mechanism are Ovivo's durable heavy duty drives. The drive is designed to handle the specified torque for 20 years of continuous operation, but we have seen drives still in operation after
We are a prominent manufacturer and service provider of high quality range of Belt Oil Skimmer, Rotating Drum Fine Screen, Belt Filter Press, Screw Conveyor, Drum Thickener, Rotary Air Lock Valve, Sludge Dewatering AMC Services and many more.We ensure that the offered products are tested on numerous quality parameters to ensure high performance at users end.
The torque capability of a thickener drive is specified as Duty Rating being the maximum mechanism design strength or the 100% setting on the Torque Control Box. The torque, in turn, depends on a K factor and the thickener diameter based on the following
hold back floating mater for removal with the skimmer. 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.

Alum sludge is a by product of drinking watertreatment processes in Ireland. It is obtained when aluminium (Al) salts are used as a chemical coagulant. Once alum sludge is dewatered, however, aluminium hydroxides become the dominant constituent, making it possible to reuse the sludge as a valuable raw material in wastewater treatment.
