Stages of Waste Water Treatment Process.
Industrial and domestic processes lead to various forms of waste including water, solids 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 common in most process including in 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 not complicated but should always be functional mode. However, septic systems serving large populations are complex since they have to absorb lots 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. A project plan is made according to the unique circumstances surrounding it. Engineers at the manufacturers will oversee the project from its design stage to monitoring and maintenance works. These types of plants are huge capital investments and are also sophisticated. The output of the system is high grade usable water hence is used at commercial levels.
The wastewater treatment plants involve three main stages. Water flows to reservoirs either by pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. The process involves use 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. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates in the water. This stage removes over 80% f the water impurities. Water passed through his phase is not hazardous to the environment.
water is however made pure by
taking it to the third stage. 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. Chlorine is used by several firms though it have become a subject of debate in the recent.
Water pumped to the treatment plant should not contain industrial chemicals. The company that is producing water containing chemicals should remove these chemicals by having a treatment plant at their base.
