Under a pressure of no more than 2.5 bars, water, mineral salts and molecules / ions are smaller than filter holes (0.1 –...

Currently, biological wastewater treatment equipment such as activated sludge is being used extensively but in practice, the operation and management have been difficult. One of them is the phenomenon of occurring bacteria caused by sludge (Sludge bulking), if the phenomenon of bulking (cause mud foam and make the density of sludge is low, difficult to settle) occurs the separation of solids – Liquid in the settling tank is not effective,...
