What is a wastewater treatment plant?
A city or municipal water treatment facility that’s treating water you drink or use in an industrial process. A city, municipal or industrial facility that’s treating wastewater. A heavy metal commonly regulated by wastewater permits.
What is a wastewater parameter?
A wastewater parameter that refers to the entire amount of toxic organic compounds present. EPA has developed a specific list of chemicals that are defined as toxic organic compounds. A type of membrane filtration that’s similar to reverse osmosis, but not as restrictive.
What is influent wastewater treatment?
Influent The untreated wastewater or raw sewage coming into a wastewater treatment plant. Influent Screens Screens used to remove large inorganic solids from the waste stream. Innovative and Alternative (I&A) An EPA term for wastewater treatment systems that reuse all or part of the wastewater.
What are permits in wastewater treatment?
These terms refer to the amount of wastewater flow over a given time period. Most wastewater permits include daily flow limits, so facilities track the flow of treatment systems to stay within overall permit parameters. A wastewater treatment technology that combines biological treatment with physical treatment involving membrane filtration.
What is a Wepa?
In Puerto Rican Spanish, wepa is a versatile slang interjection that apparently originates as an imitation of the English Woo-hoo!. The term rose to prominence in Puerto Rico thanks to the 1974 song “El Jogorio (Wepa Wepa Wepa)” by Alfonso Velez. The song was a hit in Puerto Rico and became popular throughout Latin America and the Caribbean.
Why do people use "wepa"?
The exclamation is variously used to express amazement or great happiness, often in reaction to good news. It’s particularly popular at events where people are singing or dancing, encouraging high energy, movement, and partying. Internet users tag social-media posts with “#wepa” to express the sentiment, as well.
What is a tank in wastewater treatment?
Usually in municipal wastewater treatment, a chamber or tank in which primary influent is slowed down so heavy typically inorganic solids can drop out, such as metals and plastics.
What is the process of adding a substance to wastewater?
The process whereby a chemical or other substance is added to wastewater to trap or attract the particulate suspended solids into clusters or clumps of floc or flocculent, wooly looking masses.
What is TSS in water?
As the name implies, the total solid particles that are suspended (as opposed to dissolved) in the wastewater. TSS must be filtered out, flocculated, digested and so on for removal in the treatment of wastewater. Though not necessarily pollutants TSS is considered to be a measure of pollutants in water by the EPA in the US.
What is a constructed wetland?
type of constructed wetland in which primarily treated waste flows through deep gravel or other porous substrate planted with wetland vegetation. The water is not exposed to the air, avoiding problems with odor and direct contact.
What is industrial ecology?
Industrial Ecology (IE) focuses on combining perpetually desirable outcomes in environment, economy and technology sustainably. The primary tenet is that all systems mimic nature and are thus closed loop, continuous, circular. In wastewater treatment industrial ecology would mean that all so called "waste" is re-input into the same or other process. For example, biosolids as fertilizer can be considered a use of sludge consistent with industrial ecology. Recycling wastewater into the treatment plant, manufacturing or other process is another example.
What is floc in wastewater?
Particulate and or bacterial clumps forming wooly looking clusters in wastewater. In biological processes such as extended aeration or activated sludge and others the floc contains aerobic or anaerobic microorganisms. For industrial applications flocculants are used.
What is a riparian wetland?
An artificially created wetland usually with a waterproof lining for wastewater purification. Detention, flow rates, types of plants and other parameters are controlled to improve BOD, SS and N removal. Typical riparian plants like cattails and reeds are used to provide bacteria with an oxygenating root zone.
What is wastewater permit?
These terms refer to the amount of wastewater flow over a given time period. Most wastewater permits include daily flow limits, so facilities track the flow of treatment systems to stay within overall permit parameters.
What is a control parameter for treating hexavalent chromium wastewater?
A measure that indicates the capacity of wastewater to gain or reduce electrons during a chemical reaction. It is used as a control parameter for treating hexavalent chromium wastewater in the metal finishing industry.
What is PSI in wastewater treatment?
A measurement of pressure. It’s often used when discussing physical wastewater treatment technologies involving filtration, but is also used with pumps. Filtration system PSI can indicate when it’s time to backwash or change a filter.
Why is UV light used in wastewater treatment?
In some industries, ultraviolet light is used to sterilize water treated wastewater prior to reuse or recycling. UV light keeps algae and other bacteria from growing in the recycled wastewater.
What is biological water treatment?
A biological water treatment technology commonly used in municipal wastewater treatment systems. Sometimes private industry will harness this technique to reduce certain pollutants, such as BOD and COD (see definitions below), but usually only due to compliance concerns.
What are visible solids in wastewater?
Visible solids present in wastewater that can be filtered out through traditional physical treatment technologies. In the metal finishing industry, for example, FOG (fats, oils and grease) and dirt particles might make up part of the total suspended solids.
What is RO in filtration?
RO: Reverse Osmosis. A physical treatment technology based around the use of a membrane for filtration. It provides the greatest degree of filtration available and is very effective for filtering out small or even dissolved pollutants. It is subsequently the most expensive type of filtration.
