Schematic diagram of water treatment process. Suspended particles get stuck to the chemicals to form floc. Flow diagram of municipal wastewater treatment plant. These diagrams show the flow of chemicals and the equipment involved in the process. The design of process flow sheet involves selection of an appropriate combination of various unit operations and unit processes to achieve a.
Figure 1 1 illustrates the wtp process schematic including model inputs and outputs. The four processes are. Process flow diagrams pfds are used in chemical and process engineering. The removal of bod is done by a biological process such as the suspended growth treatment process.
Surface water is more often treated rigorously than underground water as it has less contaminants. Drinking water treatment process flow diagram. Text in this example. As already stated preliminary treatment involves the removal of floating materials leaves papers rags and settleable inorganic solids.
Alum and other chemicals are added to the water at this stage. Drinking water treatment sedimentation the heavy particles floc settle to the bottom and the clear water moves to filtration. An important part of the municipal wastewater treatment is the bod removal. Flocculation clarification tank lake reservoir or river coagulation filtration.
Generally a process flow diagram shows only the major equipment and doesn t show details. The diagram below shows a basic water treatment process for surface water.

Water treatment process before arriving at your tap water is treated at the hanahan water treatment plant to remove sediment bacteria and other impurities.
The water then flows through pipes to homes and businesses in the community. Oil refining hydrodesulphurization. The process flow sheet or flow diagram is a graphical representation of the sequence in which various unit operations and unit processes are adopted for treatment of sewage at any sewage treatment plant. The plant is a member of the partnership for safe water and meets or exceeds all water quality standards.
The model simulates the following dbp formation. Choice of water treatment process choice of treatment process depends on choice of treatment process depends on. Storage water is placed in a closed tank or reservoir for disinfection to take place. The wtp model version 2 0 includes the treatment processes and disinfection options shown in table 1 1.
Real time decisions for individual public water supplies. Quality of raw water. 1 preliminary treatment 2 primary treatment 3 secondary or biological treatment and 4 tertiary or advanced treatment.
