Insight into the enhanced sludge dewaterability by tannic acid

Viscosity is a crucial indicator of sludge dewatering performance, to a certain extent, reflecting the amount of sludge extracellular biopolymer (Zhen et al., 2012). As shown in Fig. 2, for raw sludge, the viscosity of sludge supernatant decreased significantly from 21.5 mPa·s to 8.5 mPa·s with lowering pH from 6.9 to 3.0.

Beryllium Extraction and Beneficiation

Unlike aluminum, it resists corrosion by salt water, etc. Its rate of expansion with heat is the same as that of cast iron. It alloys easily with aluminum. An alloy of beryllium 70% and aluminum 30%, is one-fifth lighter than aluminum, and resists corrosion much better. In tensile strength it greatly exceeds duralumin.
