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 from the waste treatments plants include recycled products, clean water and safe, biodegradable products. The processes involved in the treatment of these wastes differs depending on the source and the type of waste. Wastewater is a produced in typical all process including 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. 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 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 systems are complex and require large capital outlay. The water released from these systems are quality clean and therefore used at commercial levels.
There are three main stages in the water treatment process. Water flows through pipes either by pumping or gravitational force to large reservoirs. In these reservoirs, there is removal of floating and suspending solids. Centrifugal force is applied at this stage. About 60% of solids will be removed at this stage. Sometimes, chemicals can be used to increase the removal of solids. water is then pumped to the secondary stage which is referred to as the 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.
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.
When water is being pumped into the treatment plant; it 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.
