Wastewater treatment systems remove contaminants from domestic or industrial sewage and wastewater. Treated wastewater must be environmentally safe for reuse as fertilizer, garden and lawn watering, industrial applications, aquifer recharge, and dust suppression.
Greywater does not contain human waste and is used for landscape irrigation and wetlands that are artificially created to restore habitats of migratory and native birds and wildlife for land reclamation. You can find the best wastewater treatment via the web.

Wastewater treatment systems are available to companies that have contaminated or flowing water and would like to treat and reuse it. These systems can be very compact to fit small areas and are easily transportable. They can be large enough to treat large amounts of greywater every day.
There are different systems for different types of wastewater, but the basic steps for treatment are:
- Pre-treatment removes large pieces and debris such as branches.
- Screening also removes small pieces of debris extracted in pre-treatment, including plastic packets, cans, rags, and sticks. This is usually done with a raking bar but can be done manually.
- Grit removal involves removing sand, small stones, and broken glass. This is mainly done in large systems, as the grit can be removed during screening in small systems.
- Larger systems remove fat and grease with skimmers that collect as they float on the surface. This is done in most plants with a mechanical surface as the primary explanation.
