In our modern society, recycling waste water is important. Hence, many countries are using the waste water purification system. This is the process whereby contaminants from water that is used and wasted is collected and processed in the name of recycling. There are many ways to go about it which includes using chemicals, doing it physically and doing it organically.
It can be treated close to where the sewage is created which is known as decentralized or an onsite system. It put in septic tanks, aerobic treatment system or in bio filters. Another alternative and the most used process is collection and transportation of network pipes and pumps stations to a municipal treatment plant popularly known as a centralized system.
Waste water comes from institutions, residential places, industrial and commercial establishments. As of household, the water is generated by toilets, bathrooms, kitchen, showers and sinks. Waste will include the industry and commerce desecrate. In developed states, the division and drainage of sewer water to black and grey water is common later being used for irrigation or flushing toilets.
It may include storm water runoff. The sewerage systems have the capacity to handle the storm water known as combined sewer system. As rainfall travel over the roofs and on grounds, it does pick up various contaminants that include soil, animal waste, oil/grease, heavy metals, and expected to ooze organic compounds. Storm water should receive some level of treatment before being let into water ways according to some jurisdictions. Treatment processes used for storm water include retention basins, buried vaults, wetlands, and media filters.
Industrial waste matter receives pre cure at the factory themselves so as to reduce the toxin load before allowing it to the sewer. The procedure is referred to as industrial waste treatment. Industrial waste contains pollutants which are irremovable via conventional sewage treatment. Allowing industrial waste directly would be harmful to the biological treatment system.
Reasons for treating sewage is for production of an effluent that does less harm as its allowed to an environment curbing pollution. The stages of treatment include the primary, secondary and tertiary treatment even though production affordability play a role in this, there is also enviromental conciousness.
Primary treatment consists of temporarily holding the sewage at a particular location where the heavy solids settle at the bottom while lighter solids float. The floating materials are removed and the liquid may be discharged or subjected to secondary treatment.
Secondary treatment involves removing is whereby suspended bio matter that is dissolved. As a means to manage the habitat, there is control in treating it; there is tertiary treatment where it involves chemical disinfection of water before leaving the controlled habitat as ir flows to other streams.
Pollution rate caused by waste water has reduced over the years and credit should be given to the system of water purification. Water wastage has also reduced as the same water can be used for other important and useful ways.
