Thickening and clarification. In challenging recycled fiber processes, reliable liquid clarification and thickening is critical for maintaining continuous and cost-effective operation. The aim of an efficient thickening and clarification system is to cost-effectively sustain a high production rate.

The advantages of sludge thickening in reducing the volume of sludge to be handled are substantial. With reference to Figure 9-3, a sludge with 1% solids thickened to 5% results in an 80% volume reduction (since 5% 1/20).A concentration of 20% solids, which might be achieved by mechanical dewatering (discussed in the next section), results in a 95% reduction in volume, with resulting savings ...

Its a good idea to understand the energy performance ratings of skylights so you can select your skylight based on the local climate and your homes design. For labeling energy-efficient skylights, ENERGY STAR has established minimum energy performance rating criteria by climate, based on more detailed ratings from the National Fenestration Rating Council (NFRC).

The ANDRITZ TD, a rotary screen thickener, is an excellent alternative to gravity belt thickeners for continuous dewatering of sludge thanks to its small space requirement. Due to the efficient and reliable thickening process and the high hydraulic capacity, the TD can remove up

Energy-Efficient Sludge Thickening. Thickening consumes far less energy than it saves during further sludge treatment. Primary and secondary sludge should be thickened separately to save power and polymer. Primary sludge can be gravity thickened to 4 6 % DS without flocculation. Sludge and supernatant removal should be automatically controlled.

The concentration efficiency is greatly accelerated, the concentration efficiency is 3 8 times of the ordinary thickener, and the underflow concentration can reach 60 70 %. 2. high - capacity drive systems and drive protection systems. The rotary rake frame is driven by a low speed hydraulic motor or drive motor through an efficient ...
