Picket Fence Thickener (Gravity Thickener) These machines are fabricated in robust designs usually made of stainless steel. Steel bridges or concrete slabs are used to carry drive unit system. There are a variety of configurations, with or without supplementary functions.
Picket Fence Thickeners have been installed in numerous water and wastewater sites such as, Didcot Water Treatment Works, Didcot, England, Forest Row, Water Treatment Works, East Sussex, England, Lough Egish Water Treatment Plant, Co. Monaghan, Ireland.
This project will be based on the Picket Fence Thickener (PFT) design of the upgrade to the Inniscarra Sludge Treatment Plant in Co. Cork. The Inniscarra Water Treatment plant currently provides potable water to a large portion of Cork City and Cork County, including areas to the west and south of the city as well as Cork Harbour and Ringaskiddy.

A&J Water Treatment has supplied dozens of WRc Thickeners and Picket Fence Thickeners into the marketplace in varying styles and sizes from as little as 1.6m diameter to 16m diameter, including package plants (tank and thickener) and fabrication in a variety of materials such as painted mild steel, 304 grade & 316 grade stainless steel for both potable water and wastewater applications.
Paramount Limited make Pickets fence thickener mechanism which is suitable for installation either in reinforced cement concrete or steel tanks. The recommended slope is 1:12 at the bottom of the clarifier tank for efficient removal of sludge. The sludge is scrapped
Picket Fence and WRc Thickeners for reliable sludge concentration. The Ham Baker Group are proud to be able to offer the benefit of our decades of experience in the design, manufacture and installation of WRc Thickeners and Picket Fence Thickeners.
The thickening tank is equipped with slowly moving vertical paddles built like a picket fence. Sludge is usually pumped continuously from the settling tank to the thickener which has a low overflow rate so that the excess water overflows and the sludge solids concentrate in the bottom.
The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener required. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment.
Sludge from the clarifiers is fed from a center well to the tank, and gravity then separates the solids, which settle downward and compact at the bottom of the tank. The scraper collects the settled solids to a discharge pipe located at the bottom of the tank, and the supernatant flows up over a V-notch weir at the top of the tank. Gravity thickening is the most common method used to thicken

Response Group manufacture Picket Fence Thickeners (PFTs) for the initial treatment of sludges in the wastewater industry, The Picket Fence Thickener is designed to promote agglomeration of the sludge particles and produce a post-clarifier sludge with higher solids concentration.
Picket Fence Primary Volute Gravity Daf Sludge Thickener On the basis of screw sludge dewatering machine, we research and develop a new sludge thickening equipment, that is Daf Sludge Thickener. Daf Sludge Thickener Selection of models:
For our clients’ peace of mind, we design all Picket Fence Thickeners (PFTs) to the relevant British Standards and Wimes standards as well as the client’s own, on-site requirements. Immersed steelwork in galvanised mild steel with epoxy paint coating as standard, other materials, such as stainless steel available on request.

PROBLEM TO BE SOLVED: To provide a scraper capable of effectively separating bubbles and water from sludge even in a rectangular sludge thickener. SOLUTION: The scraper for the sludge thickener being installed on the bottom of the thickener whose bottom is rectangular and having scraping blades which are moved back and forth, wherein picket fences are erected for separating the sludge and air
Package Sludge Thickener. Cost-effective sludge dewatering for independence in sludge disposal. The Q-PRESS® is a screw press with a conical screw shaft and cylindrical sieves consisting of three treatment zones: inlet and drive zone, three-part thickening and dewatering zone, and press zone with pneumatic counter-pressure cone.

The AMIRA P266 'Improving Thickener Technology' series of projects has sought to provide a firm scientific basis for feedwell and thickener design, a requirement as pressures on water usage in the
I thought I could use gravity thickening given that my system is just an activated sludge MLE with only N-removal. so using gravity thickener would not give room for phosphorus release as the
