Wastewater treatment plants, or facilities at plants producing wastewater, are expensive investments that do a lot of good in the world. Wastewater is any water that has been used by people to make products, wash themselves and their items, or carry away sewage. Wastewater treatment includes reclaiming water from sewage systems, industrial waste and even storm runoff so that water can be put back into the environment safely.
Healthy Environment and Individuals
Decaying organic matter is one of the things that is removed by wastewater treatment companies and their equipment. This matter, if left in, can use up the suspended oxygen that aquatic animals rely on and can be a breeding ground for harmful bacteria. Heavy metals, carcinogens and toxic chemicals are also removed by this process, so they do not create health hazards for the people, plants and animals relying on freshwater. By the end of the treatment process, both the water and removed solids are tested several times for harmful substances. The solids can sometimes be used to fertilize crops, but are disposed of by safely burying or burning depending on test results and composition.
More Water To Go Around
While not everyone is comfortable drinking reclaimed water, it is safe, and many municipalities do. Even when not connected to your tap, reclaimed water can be used for lawns, crops or industrial purposes and reduce the demand on freshwater supplies. As the population grows, demand on water sources is increased and it is better for the environment to supplement freshwater supplies with reclaimed water than it is to truck or pipe in water from remote locations.
Wastewater treatment not only helps keep harmful substances from the environment, it can lower freshwater demand when used on crops and can even be safe to drink. The treatment process filters out particulates, decaying organic matter and harmful chemicals with specialized equipment. The substances filtered out can be made into fertilizer or safely disposed of in other ways.
