Wastewater treatment systems remove contaminants from domestic or industrial sewage. These systems use biological, physical, and chemical processes to remove contaminants.
Treated wastewater must be environmentally friendly for reuse such as fertilizer, garden and lawn irrigation, aquifer filling, industrial applications, and dust suppression.
Today there are modern technologies that allow the treatment of sewage to be safely reused as drinking water. Contaminated water comes from household waste in toilets, bathtubs, showers, sinks, and kitchens. It also comes from the industry.
Wastewater treatment systems are available for companies that are contaminated with wastewater or wastewater and wish to recycle and reuse them.
There are different systems for different types of waste, but the main treatment steps are:
The pre-treatment removes large cuttings and deposits as branches. Sieving also removes a smaller portion of the waste that is disposed of during pre-treatment, including plastic packaging, cloth, boxes, and sticks.
The primary treatment used to settle sludge is sedimentation. There is a settled sludge scraper that is pushed towards the container for further treatment.
Secondary processing is to degrade the biological content of waste originating from human and food waste, as well as soap and detergents.
If the wastewater is discharged into sensitive ecosystems such as coral reefs, low-current rivers, or estuaries after secondary treatment, then tertiary treatment is carried out to sterilize the water both physically and chemically.
