gravity thickener - definition - English

In Sweden the following techniques are used: thickening (gravity thickening, flotation), stabilisation (anaerobic, aerobic, lime), conditioning, dewatering (centrifuge, filter belt press, air drying), thermal drying and composting.

Gravity Thickening: Gravity Thickeners - Walker Process

Gravity Thickeners. Back to Product Search. Type RS Pier Supported Thickeners, 30 feet and greater. The RS Thickener mechanism consists of two fabricated steel arms supported from a central rotating drive cage. The cage is suspended from an enclosed spur gear drive turntable unit which, in turn, is supported on the center pier.

Biosolids Technology Fact Sheet Gravity Thickening - EPA

xvEPA United States Environmental Protection Agency Biosolids Technology Fact Sheet Gravity Thickening DESCRIPTION Thickening is the process by which biosolids are condensed to produce a concentrated solids product and a relatively solids-free supernatant.

Sludge Thickening - Sewage Treatment - Reverse Osmosis ...

The type of thickening selected is usually determined by the size of a wastewater plant, its physical constraints and the downstream process. AES can offer gravity thickening, dissolved air flotation (DAF) thickening, centrifugal thickening, and rotary drum thickening depending upon the process application & space availability.

CA2126239A1 - Gravity type pulp washer or thickener ...

A cylinder type paper pulp washer or thickener apparatus includes a rotatable cylinder mold (12) with a forming wire surface (16). The mold (12) rotates at least partially submerged in a vat (10) of dilute paper pulp stock and a differential pressure across the wire surface draws stock from the vat through the cylinder mold (12) and forms a ...

Passavant Gravity Thickener - Aqseptence

Passavant Gravity Thickener Passavant ® Gravity Thickener offers a particularly economic solution for the mechanical thickening process. The robust, tried and tested gravity thickeners are designed for a maximum pressure of 0.58 psi on the bottom scraper blades which enables sludge thickening of up to 600 g/l (80 oz/gal), depending on the type of sludge.

The GDX™ gravity decker is mainly used for dewatering paper machine broke and for pre-thickening reject pulp. ... The drum rotates in the direction of the incoming feed, carrying the pulp underneath the drum to a compaction zone on the other side where dewatering occurs.

Trevi Environmental Solutions - Gravity thickener

Gravity thickening is the easiest way to thicken sludge. An example of a gravity based sludge thickener is the Dortmund Tank. This type of sludge thickener, very similar to a clarifier, may be applied either continuously or in batch.
