SLUDGE DEWATERING - Global Leader in Water-Soluble …

To do so, a medium range polymer is tested on the sludge by beaker to beaker pouring. The initial dosage is func- tion of the sludge concentration (ie: 5ml of a 3g/l solution in 200ml of 30g/l sludge). If a good floc- culation occurs at this dosage, the test is repeated at a lower dosage (ie: - 1ml).

OSE decanter for sludge thickening with starch polymer

Flottweg has developed an innovative method for thickening sewage sludge using starch polymers. Potato or pea starch serve as the basis for starch-based polymers. Prior to the digestion process, the excess sludge must be thickened. With conventional systems, thickening is often carried out with the aid of belt thickeners.

Sludge Thickening Technologies Reduce Wastewater COD and ...

The installation allows for the use of a polymer to help the separation but polymer is not necessarily essential. The decanter centrifuge will thicken an activated sludge without polymer producing solids at an ideal 6%-dws for land spraying applications. However, the liquid centrate remains cloudy, 0.2%-dws,...

Maximizing Polymer Value for Improved Sludge Dewatering

- Soft water helps polymer molecules fully-extend faster - Hardness over 400 ppm may need softener Oxidizer (chlorine): detrimental to polymer chains - Should be less than 3 ppm Temperature*: higher temperature, better polymer activation o- In-line water heater for water lower than 40 F - Water over 100 oF may damage polymer chains

Sewage sludge dewatering & sludge thickening | Decanters

Thickening of sewage sludge means concentrating the surplus sludge from the biological stages from 0.5 to 1 percent total dry solids to 6 to 8 percent. This reduces the sludge volume by 90 to 95 percent. The thickened sewage sludge can then be pumped into a digester.

Sludge Thickening - an overview | ScienceDirect Topics

Sludge thickening is a process in which the solids concentration is increased and the total sludge volume is correspondingly decreased, but the sludge still behaves like a liquid instead of a solid. Thickening commonly produces sludge solids concentrations in the 3% to 5% range, whereas the point at which sludge begins to have the properties of a solid is between 15% and 20% solids.

HUBER Solutions for Sludge Thickening - HUBER SE

HUBER Solutions for Sludge Thickening. 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.

Polymer Optimization for Centrifuge Dewatering

Re-treatment of solids (thickening, digestion and dewatering) Impact of inert solids on activatedImpact of inert solids on activated sludge mass calculations Throughput Pounds per How centrifuges are sized and sold hour Polymer dose Active pounds per Operating costs sw510s1.pptx/16 pounds per dry ton

Sludge Thickener - Centrisys Equipment THK Series

The Most Efficient Solution to Thicken Sludge The Centrisys Sludge Thickener (THK Series) is specifically engineered to achieve high-performance thickening of biosolids. The non-conical design results in greater G-volume, allowing for the highest capacity of flow to the centrifuge.

Sewage Sludge Thickening Without the Use of Polymer - YouTube

Feb 10, 2016 · The Deggendorf sewage plant is concentrating the surplus slurry without the use of polymer. This is a unique way of thickening sewage sludge, made possible by the Flottweg OSE Dekanter and saves ...
