Stages of Waste Water Treatment Process.
Industrial and domestic processes lead to various forms of waste including water, solids and gases. These wastes are absorbed into the environment and can be dangerous. The harm made to the environment can, however, be reduced by taking waste through treatment plants. The end products of the waste treatment plants includes clean water, harmless biodegradable and recycled 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 is carried out in three phases.
Wastewater from homes is normally treated in septic systems. 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 waste water treatment plants for use in large residential estates and factories. 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. The output of the system is high grade usable water hence is used at commercial levels.
The water treatment process ahs three main phases. Water flows through pipes either by pumping or gravitational force to large reservoirs. 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. water is then pumped to the secondary stage which is referred to as the 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. The water that is released into the environment at this stage is not harmful.
water is however made pure by
taking it to the third stage. It is referred to as the tertiary stage and water can be used for a wide range of uses. 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 responsible for releasing water with industrial chemical should take responsibility by establishing a treatment plant at their base to remove the chemicals.
