Stages of Waste Water Treatment Process.
There is release of variety of waste from both domestic and industrial such as water, solids and gases. These types of wastes are directed into the environment and cab e hazardous. The harm made to the environment can, however, be reduced by taking waste through treatment plants. The end products from the waste treatments plants include recycled products, clean water and safe, 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 is carried out in three phases.
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 help with the design and construction of wastewater treatment plant. They will design the plan according to the project specific needs. They have engineers who will oversee the whole project from the design stage to the monitoring and maintenance tasks. These types of plants are huge capital investments and are also sophisticated. 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. There is removal of floating and suspending solids in the reservoirs. Centrifugal force is applied at this stage. The process can remove the about 60% of the suspended solids. Removal of solids can be increased through addition of chemicals. The water is then directed to the second phase also known as secondary stage or 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. More than 80% of impurities in the water are 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. The phase is referred as the tertiary level and the water released is usable for a variety of uses. 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 company responsible for releasing water with industrial chemical should take responsibility by establishing a treatment plant at their base to remove the chemicals.
