treatment systems remove contaminants from household or industrial sewage and wastewater. The systems use biological, chemical and physical processes to remove the biological, chemical and physical contaminants. Treated wastewater should be environmentally safe for reuse as fertilizer, garden and lawn watering, industrial applications, aquifer recharge and dust suppression. There is the advanced technology today that makes it possible to treat sewage to be safe to reuse as drinking water.
Contaminated water comes from household waste from toilets, showers, bathtubs, sinks and kitchens. It also comes from industry and commerce. Greywater does not contain human waste and is treated to be used for landscape irrigation and wetlands that are artificially created to restore wildlife habitats for migratory and native birds and land reclamation.
Blackwater has pathogens that must be decomposed before they are safe for the environment. This can be done through composting if the water content is low enough. The heat created from thermophilic microorganisms will raise the compost to over 60 degrees Celsius. This will destroy dangerous pathogens and the blackwater will be ready for safe fertilizer after about a year.
Wastewater treatments systems are available for companies that have contaminated effluent or run-off water and would like to treat it and reuse it. These systems can be very compact to fit in small areas and are easily transported. They can also be quite large for treating huge amounts of greywater every day.
There are different systems for different types of wastewater, but the basic steps for treatment are:
Pre-treatment that removes large pieces and debris such as branches.
Screening also removes large pieces that are smaller than the debris removed in pre-treatment including plastic packets, cans, rags and sticks. This is usually done with a raking bar but can be done manually.
Removal of grit includes removing sand, small stones and broken glass. This is mainly done in large systems, because in small systems the grit may be removed during the screening.
In larger systems fat and grease is removed with skimmers that collect what is floating on the surface. This is done in most plants with mechanical surface skimmers as primary clarifiers.
Primary treatment is used to settle sludge through sedimentation. There are scrapers that drive the settled sludge towards a container for further treatment.
Secondary treatment is to degrade the biological content from sewage that comes from human and food waste as well as soap and detergents. There are several types of secondary treatment systems.
If the wastewater is to be discharged into a fragile ecosystem such as coral reefs, low-flow rivers or estuaries, there is a tertiary treatment after secondary treatment to disinfect the water chemically or physically. If it is satisfactorily purified, it can be used to recharge groundwater or irrigate crops.
Collectively, the effect of CUSTOM on industrial society has been to eliminate wastewater solutions and drastically reduce the time long associated with wastewater solutions.
To be the safest, most progressive domestic CUSTOM, relentless in the pursuit of customer and employee excellence.
A wholesaler should have many wastewater solutions based products that could help you if you have a wastewater solutions problem. It is better to treat the problem early rather than have to deal with it later. Qingdao Jinwantong Environmental Science and Technology Co., Ltd. is your best choice.
We persevere in keeping the customers pleasant and supporting them with CUSTOM at a reasonable price.
