Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water 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 waste treatment process produces harmless products such as water, recycled products and harmless, biodegradable 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.
Wastewater from homes is normally treated in septic systems. The septic system is not complicated but should always be functional mode. 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 assist you in design and construction of wastewater treatment plants. 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 systems are complex and require large capital outlay. The water released from these systems are quality clean and therefore used at commercial levels.
The wastewater treatment plants involve three main stages. water flows through pipes by means of pumping or gravitational force. In the reservoirs, there is separation of floating and suspending solids from the water. This process happens in the presence of centrifugal force. The process can remove the about 60% of the suspended solids. Chemicals can be used at times to increase the removal of solids. The water is taken to the second stage of treatment known as the secondary stage of organic stage. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates in the water. More than 80% of impurities in the water are removed at this stage. The water that is released into the environment at this stage is not harmful.
However, to make the water pure, the third stage is incorporated. This phase is known as tertiary level, and the water released here can be used for different purposes. The water may be treated using various chemicals to ensure its safety. Chlorine is used by several firms though it have become a subject of debate in the recent.
Water pumped into the wastewater treatment plant should not contain industrial chemicals. The individual factory releasing such waters should take individual responsibility by establishing a treatment plant at their base before releasing such water.
