Instructions for operation of the wastewater treatment plant or operation of the wastewater treatment package include all methods, instructions and tips that are used to repair, maintain, operate, operate and operate wastewater treatment systems.
Proper operation can increase the efficiency of water and wastewater treatment systems and on the other hand optimize operating costs.
Familiarity with the operation of different units of wastewater treatment plant for proper operation
Different wastewater treatment units are determined according to the type of wastewater entering the treatment plant, such as sanitary, hospital and industrial wastewater, and following that, the selected processes and methods for treatment. The greater the number and complexity of these units, the more specialized the operation of the wastewater treatment plant. Here are the most common ones:
Trash: Usually the first unit in a wastewater treatment plant.
Primary sedimentation: Used to remove suspended solids that may have gravitational sedimentation.
Degreasing: Used to remove fat and ranges from simple gravity degreasing to a variety of advanced processes such as DAF.
Balancer and sewage pumping station: It is used to balance and pump the incoming sewage to the treatment plant.
Aerated activated sludge: Aerated by surface or deep aeration of wastewater and provides growth conditions for aerobic microorganisms.
Biological sedimentation: In this unit, activated sludge is sedimented by gravity and separated from wastewater.
MBR membrane unit: In membrane processes, wastewater is treated by passing through a membrane or semi-permeable membrane. Operation of membrane treatment plants requires high expertise.
Disinfection: In this unit, wastewater is disinfected by various methods.
Pumping unit: In different parts of the treatment plant, for example, before pressurized filters are used to pump wastewater with a specific flow rate and pressure.
Filtration and membrane unit: Filtration can include sand filter, carbon filter, micro-filter and ultrafilter. Sand and carbon filters may be designed and operated by gravity or pressure. Membrane methods include RO reverse osmosis and NF nanofiltration methods.
Physical-chemical unit: In this process, adding chemicals to the wastewater and effluent causes coagulation, clotting and precipitation of wastewater contaminants and then these contaminants are deposited in the chemical sedimentation unit.
