Waste Water Treatment Processes
Industrial and domestic processes lead to various forms of waste including water, solids 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 treatment process for the waste depends on the source and type of waste. A typical waste product in both homes and industries is the wastewater. 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. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume of waste. Large water treatment plants for use in large factories and high residential areas are however available. 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 are a sophisticated process that requires large investments. 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 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. Sometimes, chemicals can be used to increase the removal of solids. The water is then directed to the second phase also known as secondary stage or organic stage. In this phase, the remaining biodegradable particles are provided as food to controlled organism such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. About 80% of water impurities is removed at this stage. Water passed through his phase is not hazardous to the environment.
However, to make the water pure, the third stage is incorporated. 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 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.
