Waste Water Treatment Processes
Both domestic and industrial processes leads to variety of waste including solids, water 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 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 simple and should always be functional. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume of waste. There are however waste water treatment plants for use in large residential estates and factories. There are manufacturers of wastewater treatment plants and can assist you in design and construction of wastewater treatment plants. 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 systems are complex and require large capital outlay. The output of the system is high grade usable water hence is used at commercial levels.
The water treatment process ahs three main phases. 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. The process involves use of centrifugal force. 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. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. This stage removes over 80% f the water impurities. Water passed through his phase is not hazardous to the environment.
However, to make the water pure, the third stage is incorporated. This phase is known as tertiary level, and the water released here can be used for different purposes. 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.
