Waste Water Treatment Processes
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 from the waste treatments plants include recycled products, clean water and safe, biodegradable products. The treatment process for the waste depends on the source and type of waste. Wastewater is a produced in typical all process including homes and industries. There are different stages of the wastewater treatment process.
The septic system is used to treat water in most homes. 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. Large water treatment plants for use in large factories and high residential areas are however available. There are manufacturers of wastewater treatment plants that can help you design and manufacture a treatment plant. A project plan is made according to the unique circumstances surrounding it. 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 either by pumping or gravitational force to large reservoirs. In these reservoirs, there is removal of floating and suspending solids. This process happens in the presence of centrifugal force. About 60% of solids will be removed at this stage. Chemicals can be used at times 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. More than 80% of impurities in the water are removed at this stage. The water that is released into the environment at this stage is not harmful.
The third stage is however introduced to make the water pure. The phase is referred as the tertiary level and the water released is usable for a variety of uses. Various chemicals are applied to remove the impurities and ensure that it is safe. 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.
