6-1 Role of chemical Unit Processes In Wastewater Treatment The principal chemical unit processes used for wastewater treatment include(1)chemical coagulation, (2) chemical precipitation, (3)chemical disinfection, (4) chemical oxidation, (5)advanced oxidation processes, (6)ion exchange

Operations used for the treatment of wastewater in which change is brought about by means of or through the application of physical forces are known as physical unit operations. Because physical unit operations were derived originally from observations of the physical world. they were the first treatment methods to be used. Today, physical unit operations, as shown on Fig. 5-1, are a major part of most wastewater

The constituents of concern found in wastewater are removed by physical, chemical, and biological methods. The individual methods usually are classified as physical unit operations, chemical unit processes, and biological unit ds in which the application of physical forces ohysical unit operations include pr T3clarifiers

Determining wastewater flowrates and constituent mass loadings is a fundamental step in initiating the conceptual process design of wastewater treatment facilities. Reliable data for existing and projected flowrates affect the hydraulic characteristics, sizing, and operational considerations of the treatment system components. Constituent mass loading, the product of constituent concentration and flowrate
