Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water and gases. The wastes are absorbed into the environment and cab harmful, However, taking these wastes through treatment process reduces harm made to the environment. The waste treatment process produces harmless products such as water, recycled products and harmless, biodegradable products. The choice of treatment plant is dependent 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.
Most homes treat their water using the septic system Though the septic system is simple, it should always remain 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 and can help with the design and construction of wastewater treatment plant. The process needs to be carried out per the circumstances. The manufacturers have engineers who handle the project since its inception to monitoring and maintenance works. These are a sophisticated process that requires large investments. The water released from these systems are quality clean and therefore used at commercial levels.
The water treatment process ahs three main phases. Water flows to reservoirs either by pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. The process involves use of centrifugal force. The process can remove the about 60% of the suspended solids. Removal of solids can be increased through addition of chemicals. 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. The organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients in the water. More than 80% of impurities in the water are removed at this stage. Water passed through his phase is not hazardous to the environment.
The third stage is however introduced to make the water pure. The phase is referred as the tertiary level and the water released is usable for a variety of uses. Various chemicals are applied to remove the impurities and ensure that it is safe. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
Water pumped into the wastewater 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.
