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 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. The wastewater treatment process is carried out in three phases.
The septic system is used to treat water in most homes. Though the septic system is simple, it should always remain functional. However, septic systems serving large populations are complex since they have to absorb lots 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. These systems remove quality clean water and thus 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. The process involves use of centrifugal force. The process can remove the 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. 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 released to the environment at this stage is not harmful.
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 individual factory releasing such waters should take individual responsibility by establishing a treatment plant at their base before releasing such water.
