Waste Water Treatment Processes
There is release of variety of waste from both domestic and industrial such as water, solids and gases. These wastes are absorbed into the environment and can be dangerous. However, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. The end products of the waste treatment plants includes clean water, harmless biodegradable and recycled products The choice of treatment plant is dependent 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. 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 and can assist you in design and construction of wastewater treatment plants. The process needs to be carried out per the circumstances. 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. These systems remove quality clean water and thus used at commercial levels.
The wastewater treatment plants involve three main stages. Water flows to reservoirs either by pumping or gravitational force. In the reservoirs, there is separation of floating and suspending solids from the water. This process happens in the presence of centrifugal force. The stage removes about 60% of the suspended solids. 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. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates in the water. About 80% of water impurities is removed at this stage. Water passed through his phase is not hazardous to the environment.
However, to make the water pure, the third stage is incorporated. The phase is referred as the tertiary level and the water released is usable for a variety of uses. The water may be treated using various chemicals to ensure its safety. Some firms use chlorine to remove all impurities though it has become a subject of discussion in the recent.
Water pumped to the 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.
