Stages of Waste Water Treatment Process.
Both domestic and industrial processes leads to variety of waste including solids, water and gases. These types of wastes are directed into the environment and cab e hazardous. 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 processes involved in the treatment of these wastes differs depending on the source and the type of waste. Wastewater is common in most process including in homes and industries. The wastewater treatment process is carried out in three phases.
The septic system is used to treat water in most homes. The septic system is not complicated but should always be functional mode. Nevertheless, septic systems that serve several homes are more 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. 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 are a sophisticated process that requires large investments. These systems remove quality clean water and thus used at commercial levels.
The wastewater treatment plants involve three main stages. Water flows through pipes either by pumping or gravitational force to large reservoirs. In these reservoirs, there is removal of floating and suspending solids. The process involves use of centrifugal force. About 60% of solids will be removed at this stage. Removal of solids can be increased through addition of chemicals. 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 organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients in the water. About 80% of water impurities is removed at this stage. Water released to the environment at this stage is not harmful.
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. The water may be treated using various chemicals to ensure its safety. Chlorine is used to purify the water though it has been disputed in the recent times.
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.
