Wastewater can be anything from the water that flows down the sink or toilet to the runoff from rain that may enter a storm drainage system. Wastewater treatment services remove a variety of contaminants from water to make it usable again. The benefits of such treatment depend on the nature of the contaminants in the water and the end use of the that is being water treated.
In nature, water gets renewed and purified through evaporation and rain. But when we use this water for residential and commercial purposes it can become contaminated and needs to be cleaned again before it can be used. Nature will slowly clean wastewater over a period of time, but we have to be careful with water since only a small portion of it is potable or drinkable for humans.
1. Wastewater treatment services
Wastewater treatment services are the mechanisms and processes used to treat wastewater that is produced as a by-product of residential or industrial activities. Once it has been treated it can be reused or released to a sanitary sewer or into surface water in the local environment. Almost every industry produces some wastewater but in recent years developed countries have tried to lessen production and recycle such wastewater within the production process. Some industries simply cannot completely reduce their production of industrial wastewater. They need a wastewater treatment services.
These industries must have system to treat their wastewater products and ensure that both safety precautions and discharge regulations required under regional and national legislation are met. This helps them reduce their impact on the environment and on human health, and also assists in making the products that are produced at their facilities more environmentally sensitive. They have little choice to but to do this because failure to meet the regulations will result in hefty fines and penalties. They might even lose their license to operate in some jurisdictions if they are not careful about how they handle their wastewater.
2. Components of wastewater treatment
The basic wastewater treatment system will have a number of components that are designed to perform certain functions. They will often have a clarifier, a chemical feed, a filtration sub-system and some measures for post treatment of the industrial wastewater. The clarifier is used to settle any suspended solids that may be present as a result of treatment.
The chemical feed helps to facilitate the precipitation, flocculation, or coagulation of any metals and suspended solids. The filtration process works to remove any leftover trace amounts of suspended solids before a final pH adjustment and any post treatment that may be required to meet the necessary regulations.
3. How does a wastewater treatment system work?
Wastewater treatment services are usually comprised of several individual technologies that address the specific wastewater treatment needs of any facility or locality. The wastewater treatment system should be able to handle a number of different factors including process variations in contamination and flow and the variations in water chemistry needs. It should also be capable of dealing with the required chemical volumes adjustments and possible changes in water effluent requirements.
4. Removing dangerous chemicals
Wastewater treatment services will remove biochemical oxygen demand, or BOD. That refers to the amount of dissolved oxygen needed by aerobic biological organisms to break down organic matter into smaller molecules. The system also removes nitrates and phosphates that can lead to excessive growth of harmful weeds, algae, and phytoplankton.
These can kill any nearby living organisms and lead to environmental dead zones. Wastewater treatment gets rid of pathogens that may be in the form of bacteria, viruses, fungi, or any other microorganisms that can contribute to many health concerns and spread illnesses and diseases. These might include cholera, dysentery, salmonellosis, hepatitis A, botulism, and giardiasis.
5. Removing harmful metals
Wastewater treatment services will also remove metals that can cause extensive damage to the environment and human health and total suspended solids that can harm aquatic life. These solids can decrease levels of oxygen in aquatic environments and kill off insects. The treatment will also remove pesticides and chemicals that are dangerous to both human and animal health. Some of these dangerous chemicals might include diethylstilbestrol, dioxin, PCBs, DDT, and other pesticides.
