Wastewater treatment is a method by which pollutants are removed from effluent and converted into wastewater that can return to the water pipes. As the wastewater returns into the water cycle, wastewater has a reasonable effect on the surrounding or reuse for a variety of applications (so-called water reclamation). The treatment procedure done in a wastewater treatment plant. There are different types of effluents that can treat in the right kind of treatment plant. In the case of local sewage (also known as municipal sewage), the wastewater treatment plant is known as a sewage treatment plant. In the case of industrial effluent, the treatment done in another industrial sewage treatment plant. Other types of sewage treatment plants are leachate treatment plant and agricultural treatment plant.
The main goal of wastewater treatment is to enable the safe disposal or reuse of purified wastewater. However, in order to use the correct wastewater treatment method, you need to consider the choice of disposal or reuse prior to treatment.
Types of treatment plants
1) Sewage Treatment Plants
Wastewater treatment (or domestic wastewater treatment, urban wastewater treatment) is wastewater treatment aimed at removing pollutants from wastewater and producing wastewater that is suitable for discharge into the environment or for expected reuse. It is a type of sewage that prevents sewage from being polluted. Wastewater treatment. The wastewater includes household and commercial wastewater as well as industrial wastewater that can be pretreated. There are many methods of wastewater treatment. These can range from distributed systems (including on-site sewage treatment plants) to large centralized systems that include a network of pipelines and pumping stations (called sewers) that carry wastewater to treatment plants.
There are many wastewater treatment technologies, most of which use biological purification procedures. Engineers and decision-makers must consider technical and economic criteria, as well as the quantitative and qualitative aspects of each option, when selecting the appropriate technology. In general, the main selection criteria are the aspects of the expected quality of the wastewater, expected construction and operating costs, space availability, energy requirements and sustainability. In less densely populated rural areas and developing areas, the sewer system is generally not treated via the sewer system, but via a large number of on-site wastewater disposal systems. These systems have a septic tank linked to drainage area, on-site sewage systems (OSS), earthworm filter systems, and more. On the other hand, modern and relatively expensive wastewater treatment plants in affordable cities can include tertiary treatment and disinfection, as well as fourth-stage treatment to remove traces of pollutants.
2) Industrial wastewater treatment plants
This process explains the process by which industrially generated effluent is treated as a bad by-product. After treatment process, the output sewer water can reuse or discharge into environmental sewers or surface water. The wastewater generated in some industrial plants may also treat in sewage treatment plant.
For most industrial processes such as oil refineries, chemical plants and petrochemical plants, make sure that the concentration of pollutants in the treated wastewater meets the requirements for discharging wastewater into sewers, rivers, lakes or the sea. It has its own special wastewater treatment system. Installations. Regulation. It is suitable for industries that produce wastewater that contains high concentrations of organic substances (such as oils and fats), toxic pollutants (such as heavy metals and volatile organic compounds), or nutrients such as ammonia.
3) Agricultural wastewater treatment plants
Agricultural wastewater treatment is agricultural management to control pollution caused by restricted animal activities and surface runoff that may be contaminated by fertilizers, pesticides, animal manure, crop residues or chemicals in irrigation water. It’s an agenda. Agricultural wastewater treatment is necessary for continuously restricted animal farms (e.g., milk and egg production). This can be done in factories that use mechanized treatment facilities similar to industrial wastewater. When using a pond, the seasonal conditions of the breeding or harvesting cycles can lower the operating costs of settling basins and transmitter ponds.
