Why add chlorine to treated wastewater?
This refers to the addition of chlorine, usually to treated wastewater, for the purpose of disinfection – to kill off most of the harmful bacteria that may still be in the liquid at this point.
How much chlorine should be added to wastewater?
Usually enough chlorine is added so that there will be, at least, 0.5 parts per million of chlorine in the mixture after 20 minutes of contact time. The actual amount and contact time will be specified by the regulatory agency.
Where does treated plant effluent go?
Treated plant effluent usually goes into a river, lake, or stream. Users of this water downstream from the plant are called downstream users.
What is activated sludge?
A method of biological treatment which produces a high quality effluent. It is a secondary process, usually following primary treatment. The activated sludge removes finely divided, suspended and dissolved organic matter remaining in the wastewater. When we talk about activated sludge, we are referring to the biological communities of microorganisms which are developed in the aeration tank. If supplied with enough dissolved oxygen, they will aerobically decompose organics in the waste water. Activated sludge is settled from wastewater and returned to the aeration tank for reuse.
Why is oxygen important in wastewater treatment?
The oxygen helps the bacteria to digest the pollutants faster. The water is then taken to settling tanks where the sludge again settles, leaving the water 90 to 95 percent free of pollutants. The picture below shows the settling tanks in the Winnipeg Wastewater Treatment Plant.
How do Cities Treat Wastewater, to Make it Safe for Discharge?
There are several levels of wastewater treatment; these are primary, secondary and tertiary levels of treatment. Most municipal wastewater treatment facilities use primary and secondary levels of treatment, and some also use tertiary treatments. The type and order of treatment may vary from one treatment plant to another, but this diagram of the Ottawa-Carleton wastewater treatment plant illustrates the basic components.
What about industrial waste? Can public wastewater treatment plants really remove all of those toxic chemicals?
Commercial and industrial waste is not sent directly to public wastewater treatment plants, because the public wastewater treatment system cannot effectively remove all of the contaminants. Wastewater from commercial and industrial processes is usually divided into the following four categories and dealt with accordingly:
Who is Responsible for Making Sure that Wastewater is Treated Properly?
Similar to drinking water provisions, the federal government has delegated responsibility for wastewater treatment to the provinces and territories. There are two federal acts, however, that may apply to wastewater. The Fisheries Act prohibits the release of harmful substances into waters that fish live in. The Canadian Environmental Protection Act governs the release of toxic substances into the environment and allows the federal government to develop regulations for the use of toxic substances.
How to reduce pressure on septic system?
Following some water conservation practices can greatly reduce pressure on your septic system. For more information about conserving water, see the fact sheet about Water Consumption. Here are a few things that you can do to care for your septic system: 1 Do not use your drain or toilet as a garbage disposal; avoid putting dental floss, diapers, coffee grounds and paper towel down the drain, as they can clog up your septic system. 2 Spread your loads of laundry out over the week. When too much water is added to the septic tank, it does not have time to treat wastes, and you could be flooding your drainfield with wastewater. 3 Plant grass on your drainfield, but keep trees and shrubs away from it, because roots can clog the system and cause damage. 4 Do not drive on your drainfield, because this can compact the soil and damage the septic system components.
How is sludge treated?
The sludge that is removed from the settling tanks and the scum that is skimmed off the top during the primary steps are treated separately from the water. Anaerobic bacteria (anaerobic bacteria do not require oxygen) feed off of the sludge for 10 to 20 days at temperatures around 38 degrees Celsius. This process decreases the odour and organic matter of the sludge, and creates a highly combustible gas of methane and carbon dioxide, which can be used as fuel to heat the treatment plant. Finally, the sludge is sent to a centrifuge, like the one shown in the picture below. A centrifuge is a machine that spins very quickly, forcing the liquid to separate from the solid. The liquid can then be processed with the wastewater and the solid is used as fertilizer on fields.
How much oxygen is removed from water?
The primary treatment generally removes up to 50 percent of the Biological Oxygen Demand (BOD; these are substances that use up the oxygen in the water), around 90 percent of suspended solids, and up to 55 percent of fecal coliforms.

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 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 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 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.
Is wastewater treated industrial or municipal?
Paper and pulp mills' treatment of wastewater is an example of industrial wastewater treatment. Municipal wastewater treatment would be an example not considered to be industrial.
What is biological water treatment?

What is wastewater treatment?
Wastewater treatment, also called sewage treatment, the removal of impurities from wastewater, or sewage, before it reaches aquifers or natural bodies of water such as rivers, lakes, estuaries, and oceans.
What are the processes used in wastewater treatment?
Sewage treatment facilities use physical, chemical, and biological processes for water purification. The processes used in these facilities are also categorized as preliminary, primary, secondary, and tertiary. Preliminary and primary stages remove rags and suspended solids. Secondary processes mainly remove suspended and dissolved organics.
What is the polluted form of water generated from rainwater runoff and human activities?
Wastewater is the polluted form of water generated from rainwater runoff and human activities. It is also called sewage. It is typically categorized by the manner in which it is generated—specifically, as domestic sewage, industrial sewage, or storm sewage (stormwater).
Why is water polluted?
In broad terms, water is said to be polluted when it contains enough impurities to make it unfit for a particular use, such as drinking, swimming, or fishing. Although water quality is affected by natural conditions, the word pollution usually implies human activity as the source of contamination. Water pollution, therefore, is caused primarily by ...
Why is pretreatment important in wastewater treatment?
For example, pretreatment of industrial wastewater, with the aim of preventing toxic chemicals from interfering with the biological processes used at sewage treatment plants, often became a necessity.
Where does industrial wastewater come from?
Industrial wastewater comes from discharges by manufacturing and chemical industries. Rainwater in urban and agricultural areas picks up debris, grit, nutrients, and various chemicals, thus contaminating surface runoff water. Read more below: Sources of water pollution.
Does dilution prevent pollution?
Densely populated communities generate such large quantities of sewage, however, that dilution alone does not prevent pollution. This makes it necessary to treat or purify wastewater to some degree before disposal. Get a Britannica Premium subscription and gain access to exclusive content. Subscribe Now.
Preliminary treatment
Here we have our focus on removing inorganics, sand/grint and rubbish. To protect downstream equipment like pumps. For the inorganics it is also because we are not interested to have it in the (primary or secondary) sludge otherwise.
Primary treatment (or pre-treatment)
With our focus on biological wastewater treatment we aim for a proper preliminary, primary or pre-treatment. Ideally all those compounds should be removed from the water, that could otherwise negatively impact the performance off downstream bioreactor (s), instruments, membranes, etc.
Secondary treatment
Secondary treatment is what we describe as the main treatment to be done. Basically it is done in a biological pathway.
Tertiary treatment
Sometimes the purified wastewater (from secondary treatment) is not of good enough quality for discharge. In such cases additional purification might be needed. Some examples:
Sludge treatment
From the primary treatment (pre-treatment) and secondary treatment (bio-treatment) a sludge will be separated. That sludge contains also carbon, nitrogen and phosphorus. By removing the sludge from the WWTP also those components are removed (from the water line). Nevertheless, it is not just like that.
