How to Make Wastewater Treatment More Environmentally-Friendly

When your town is looking for environmentally friendly wastewater treatment, there are new technologies available for this purpose. Some cities have citizens who have filed complaints about the pollutants in wastewater because this water trickles into local waterways and groundwater. This can lead to contamination of clean drinking water, causing serious illnesses. However, some of the ways that scientists sanitize water is as dangerous as the pollutants are, so researchers are finding eco-friendly ways to clean wastewater. Here are the ways that a town can clean wastewater safely.

Looking for environmentally friendly - How to Make Wastewater Treatment More Environmentally-Friendly

Aerated Lagoon Systems

Small towns without a lot of money for wastewater treatment can use an aerated lagoon system. This natural process requires having enough land for the pond that holds wastewater, and it also requires using artificial aeration devices to circulate air through the sludge. There are both facultative and suspension-aerated lagoons that require different amounts of energy. Air circulation is completed by using compressed air or a variety of motor-driven aerator devices.

Vacuum Evaporation

The process of vacuum evaporation requires a large metal holding tank that can destroy the pathogens in an enormous amount of wastewater. This is a clean process that uses pressure to reduce the vapor pressure of the contaminated wastewater. The intense pressure from a vacuum evaporation device will boil the wastewater to destroy pathogens without using heat. This type of wastewater treatment is popular in industrial manufacturing plants.

Filtration Machines

Filtration machines are another way to remove bacteria and other particulates from filthy wastewater. With this method, wastewater must flow through specialized filters that will capture pathogens that cause illness in humans and animals. There is a wide variety of wastewater filtering devices, that are used for different purposes. The filters that capture the contamination in wastewater are sanitized with solvents, or the items are thrown away and replaced occasionally.


With bio-retention, contaminants and sediments are removed from wastewater using a natural treatment area that consists of plants, soil, mulch or sand. The wastewater passes through multiple layers of organic materials to filter particulates without using man-made chemicals. The center of a bio-retention pond is depressed so that the wastewater must flow through the materials. Not only is the wastewater cleaned, but also, it aerates the water during this process to reduce foul odors.

When cities, manufacturing plants or individuals are looking for eco-friendly ways to clean water, there are numerous choices that are perfect for different locations.
