GRAVITY THICKENING OF ACTIVATED SLUDGE By William L. Donovan, Jr. Graduate Trainee and Research Assistant two types of continuous thickeners may be used Laboratory columns varying from 0.5 2 ft. in diameter, and was the best relationship between settling velocity and concen tration. Rearranging equation (2), we obtain
The Ovivo 174; 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.
3 Drum thickeners for easy and efficient sludge thickening PRINCIPLE The PowerDrum thickeners ensure dynamic thickening by rotating sludge continuously.
The thickening is the first step, often unavoidable, reduced volume of sludge removed from the water system. It optimizes the steps of conditioning, stabilization and dehydration by reducing the sizes of structures and operating costs.
Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and digested sludge can be better gravity thickened than secondary sludge.
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.
To meet diverse requirements of our prestigious clients, we are engaged in providing an excellent range of Sludge Thickeners. The offered thickeners are manufactured using the finest quality components and advanced technology in sync with industry norms.
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 .
Description. Conventional Thickeners are generally incorporated in heavy duty applications when the underflow density is high and substantial torques are required to convey the settled solids from the periphery to the central outlet for pumping away.
Rotary Sludge Thickeners is considered as amongst most demanded products that we are engaged in manufacturing and supplying these products in bulk as per the needs of our customers.
Good sludge thickening is required as a prerequisite for the efficient further treatment or dewatering of sewage sludge. The HUBER ROTAMAT174; Screw Thickener RoS 2 is a very high performance efficient system for thickening waste activated sludge

Best In Class Performance Municipal Sludge Thickener. The Monster Drum Sludge Thickener offers best in class performance for sludge wastewater treatment. This sludge dewatering equipment is designed for achieving 5 15% solids depending on the type of sludge.
The sludge thickening system is designed to take low concentrated sludge (1 2% solids) and increase the sludge concentration to 4 5% solids by means of gravity settling on a continuous basis.
Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs.
Sludge Thickeners are used to thicken sludge from settling tanks in both municipal and industrial purification plants. Functions The Sludge Thickener increases the concentration of the sludge due to its slow moving arms and vertical pickets.
The thickeners are designed to give the best possible concentration of solids into sludge. This reduces sludge volume, which means less need for dewatering and reduced overall sludge disposal costs. Optional features can include inlet diffusers, scum control and sludge blanket monitoring.
The remaining primary sludge and all of the waste activated sludge are mixed, diluted with plant effluent, and discharged to six gravity thickeners. The thickened sludge is discharged to two sludge holding tanks, 260,000 gal capacity each, and subsequently dewatered by vacuum filtration and incinerated.

All HUBER thickening systems guarantee an adjustable final solids content and meet the highest separation requirements. With regard to the economical further treatment and disposal of sewage sludge, it is necessary to reduce the sludge volumes produced within the course of the wastewater treatment process.

There are two basic types of high rate thickener units Lamina or tube settlers and solids recirculation units Lamina Thickeners They contain space cutting baffles that intercept settling paths at many levels. Solids settle out onto the baffles and are removed from suspension after settling only a short distance. Where and to the extent that removals are governed by settling rates, such
Starch thickeners give food a transparent, glistening sheen, which looks nice in a pie filling, but a bit artificial in a gravy or sauce. If you want high gloss, choose tapioca or arrowroot. If you want low gloss, choose cornstarch.
