Stages of Waste Water Treatment Process.
There is release of variety of waste from both domestic and industrial such as water, solids and gases. These wastes are absorbed into the environment and can be dangerous. However, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. The end products of the waste treatment plants includes clean water, harmless biodegradable and recycled products The treatment process for the waste depends on the source and type of waste. Wastewater is a produced in typical all process including homes and industries. The wastewater treatment process involves various stages.
The septic system is used to treat water in most homes. The septic system is simple and should always be functional. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume of waste. There are however wastewater treatment plants for use in high factories and residential estates. There are manufacturers of wastewater treatment plants that can help you design and manufacture a treatment plant. They will design the plan according to the project specific needs. The manufacturers have engineers who handle the project since its inception to monitoring and maintenance works. These types of plants are huge capital investments and are also sophisticated. These systems remove quality clean water and thus used at commercial levels.
There are three main stages in the water treatment process. Water flows to reservoirs either by pumping or gravitational force. In the reservoirs, there is separation of floating and suspending solids from the water. Centrifugal force is applied at this stage. The stage removes about 60% of the suspended solids. Chemicals can be used at times to increase the removal of solids. The water is then directed to the second phase also known as secondary stage or organic stage. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. This stage removes over 80% f the water impurities. Water released to the environment at this stage is not harmful.
The third stage is however introduced to make the water pure. This phase is known as tertiary level, and the water released here can be used for different purposes. There is application of different water treatment chemicals to make it safe. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
Water pumped to the treatment plant should not contain industrial chemicals. The company responsible for releasing water with industrial chemical should take responsibility by establishing a treatment plant at their base to remove the chemicals.
