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. 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.
Wastewater from homes is normally treated in septic systems. The septic system is simple and should always be functional. However, septic systems serving large populations are 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. They will design the plan according to the project specific needs. They have engineers who will oversee the whole project from the design stage to the monitoring and maintenance tasks. These systems are complex and require large capital outlay. The water released from these systems are quality clean and therefore used at commercial levels.
The water treatment process ahs three main phases. Water flows through pipes either by pumping or gravitational force to large reservoirs. 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. Sometimes, chemicals can be used to increase the removal of solids. The water is taken to the second stage of treatment known as the secondary stage of 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. About 80% of water impurities is removed at this stage. Water passed through his phase is not hazardous to the environment.
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. Various chemicals are applied to remove the impurities and ensure that it is safe. Some firms use chlorine to remove all impurities though it has become a subject of discussion 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.
