What are the different types of wastewater treatment technology?

Sewage treatment plants use chemical and physical screening processes to remove sewage and other particles from the water.

Wastewater refers to any water that has been altered or affected by human actions or functions. This includes sewage, rainwater that comes into contact with streets or highways, and water that has been polluted by industrial means. There are several forms of wastewater treatment technology, each being used for specific levels of contamination. They are often used in combination to ensure that the water is returned to the most natural state possible and is safe for human consumption.

Methanol helps purify water by encouraging the growth of certain carbon-emitting bacteria.

Primarily, wastewater treatment technology is implemented in an on-site sewage facility. Water passes through pipes in homes and buildings, through underground sewer systems, and then into facilities where it is purified, sanitized and treated in a variety of ways. The overall objective is to eventually return the water to potable water reservoirs and other storage facilities where it will be available for reuse.

Newer systems use ozone to treat wastewater.

Aerobic wastewater treatment technology involves the use of “good” bacteria. These organisms are generally of an oxygen-dependent variety, meaning that adequate amounts of oxygen must be present in order for them to survive. Bacteria destroy harmful microorganisms and, in the process, release carbon dioxide and water as waste products. These compounds are harmless and necessary for the decontamination of drinking water.

Gates are sometimes used to control outflows of waste or other liquids in sewage treatment plants and systems.

Another type of wastewater treatment technology uses microfiltration or synthetic membranes. These are essentially filters designed small enough to capture even tiny microorganisms, removing them from the water. Waste water is moved through the filters more than once to ensure proper filtration. This method is usually used in combination with chemicals, which are added for further decontamination. Chemical additives such as chlorine can then be filtered back out of the water using the same filtration methods, leaving the water pure and fresh.

Waste water eventually becomes potable water.

Denitrification uses methanol to purify water, encouraging the growth of certain bacteria that release carbon. The carbon then neutralizes or removes nitrates from the water. Nitrates can be harmful for human consumption and have been linked to a number of health problems such as cancer. They are usually found in polluted waters that have been contaminated by roads or factories. This water can contain relatively high amounts of oil, fluids and tar residues; all containing nitrates and other harmful toxins.

Many municipal water treatment plants process millions of gallons of wastewater every day.

The latest wastewater treatment technology uses ozone, which is manufactured by an ozone generator. The generator produces bubbles containing ozone that are continuously percolated through the water for a certain period of time, neutralizing and decontaminating it. This method provides the same effects as the others, without the use of harsh chemicals. Ozone treatment can still be used in combination with other methods to get the best results.
