Sludge is pumped from the primary clarifiers to the cyclone grit separators. The grit removed by the two separators is dewatered before disposal. The de-gritted primary sludge from SEP 1131 flows to the mixed sludge distribution chamber, where it is mixed with WAS and conveyed to the center feed well of the gravity thickener. Secondary effluent may

— As the rakes are turned by the drive shaft they cause the concentrate that has settled onto the bottom of the thickener to be pulled into the discharge chamber at the centre of the thickener. This is called the CONE. It is from this cone that the thickener underflow is taken. During normal operations of the circuit, the thickener may be pulled ...

— For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump box that causes this pressure …

— Cornstarch. Much like agar-agar, cornstarch is a great gluten-free and neutral-tasting thickening powder made from corn kernels. The ratio of cornstarch to liquid should be about one tablespoon of cornstarch per cup of liquid. If you wanna apply it to your sauce, just mix it with a small amount of water or other liquid to create a slurry.

A Thickener by definition produces thick mud - but how thick is enough? This is often best considered with reference to a Yield Stress Curve with yield stress in pascals plotted against underflow density.

Thickener . The Primary purpose of thickening is to increase the concentration of large quantity of suspended solids in the feed stream. It functions very similar to that of a clarifier but process result is different. Thickening process involves higher torques than Clariflocculator. Hence the gearbox and mechanism are of heavy duty.

— Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.
