This document discusses various advanced methods for waste water management, including the following key processes: 1. Chemical coagulation uses positively charged chemicals like aluminum sulfate to attract negatively charged particles in turbid water, causing them to clump together and settle out. 2. Centrifugation is a separation process that uses centrifugal force to promote accelerated settling of particles in a solid-liquid mixture. 3. Thermal desalination uses energy to evaporate water and subsequently condense it, providing an efficient option when waste heat or electricity is available.
