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. 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 a produced in typical all process including homes and industries. The wastewater treatment process involves various stages.
Most homes treat their water using the septic system The septic system is simple and should always be functional. 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. 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 through pipes by means of pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. This process happens in the presence of centrifugal force. 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. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates 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. 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. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
When water is being pumped into the treatment plant; it 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.
