UV ozone
a powerful wastewater treatment process employing ozone in solution and ultraviolet light; oxidises COD and toxic substances, removes colour and disinfects ...
wastewater treatment works A facility that receives influent wastewaters (and sometimes runoff accumulated in the collection system) from domestic and/or industrial sources and, by a combination of physical, chemical, and biological processes.
Wastewater treatment: The processing of wastewater for the removal or reduction of contained solids or other undesirable constituents.
Wastewater Treatment Plan: A facility containing a series of tanks, screens, filters, and other processes by which pollutants are removed from water. Most treatments include chlorination to attain safe drinking water standards.
Wastewater Treatment Plant: A facility that receives wastewater (and sometimes runoff) from domestic and/or industrial sources, and by a combination of physical, chemical, ...
Wastewater treatment: Any of the mechanical or chemical processes used to modify the quality of wastewater in order to make it more compatible or acceptable to humans and the environment.
on-site wastewater treatment systems
Systems that treat wastewater where it is produced and release treated wastewater back into the environment. These systems are smaller in scale than municipal central sewer and treatment plants.
osmosis ...
A wastewater treatment unit that is designed to treat wastewater that does not meet the sewage discharge standards so that it meets or exceeds those standards. Pretreatment units usually require a permit from a local agency.
A wastewater treatment unit that contains medium material with bacteria. The stream of wastewater is trickled over the medium and the bacteria break down the organic wastes. Bacteria are collected on the filter medium.

Wastewater treatment - A facility designed to receive the wastewater from domestic sources and to remove materials that damage water quality and threaten public health and safety when discharged into receiving streams or bodies of water.
Advanced wastewater treatment The removal of any dissolved or suspended contaminants beyond secondary treatment, often this is the removal of the nutrients nitrogen and/or phosphorus.
...
Advanced Wastewater Treatment
Any treatment of sewage that goes beyond the secondary or biological water treatment stage and includes the removal of nutrients such as phosphorus and nitrogen and a high percentage of suspended solids.
A advanced wastewater treatment
Definition (english only)
The process which remove pollutants not adequately removed by secondary treatment, particularly nitrogen and phosphorus; accomplished by means of sand filters, microstraining, ...
Bar Screen- In wastewater treatment, a device used to remove large solids.
First steps in wastewater treatment; screens and sedimentation tanks are used to remove most materials that float or will settle. Primary treatment removes about 30 percent of carbonaceous biochemical oxygen demand from domestic sewage.
Pristine ...
Digester: In wastewater treatment, a closed tank; in solid-waste conversion, a unit in which bacterial action is induced and accelerated in order to break down organic matter and establish the proper carbon to nitrogen ratio.
Here sludge from a wastewater treatment facility is being applied to a forest site. This will increase the organic matter on the site.
secondary treatment Stage of wastewater treatment wherein bacteria are used to break down organic materials and significantly reduce biochemical oxygen demand.
PRETREATMENT: A process in wastewater treatment where metal screens are used to remove large objects and chunks of debris.
PRIMARY TREATMENT: The first process in wastewater treatment where solid matter is removed.
The biological portion of wastewater treatment which uses the activated sludge process to further clean wastewater after primary treatment.
Sedimentation
The settling of solids in a body of water using gravity.
Primary treated water. First major treatment in a wastewater treatment facility, usually sedimentation but not biological oxidation.
Residual: The amount of a pollutant remaining in the environment after a natural or technological process has taken place, e.g., the sludge remaining after initial wastewater treatment, ...
Comminution: Mechanical shredding or pulverizing of waste. Used in both solid waste management and wastewater treatment.
Decomposition of complex organic materials by microorganisms. Occurs in self-purification of water bodies and in activated sludge wastewater treatment.

The most effective emission controls involve the redesign of the process so less waste is produced at the source. Common emission controls are wastewater treatment plants, stack scrubbers and in-plant, solid waste reduction programs.
Disposal Facility
A landfill, incinerator, or other facility which receives waste for disposal. The facility may have one or many disposal methods available for use. Does not include wastewater treatment. ...
