Stages of Waste Water Treatment Process.
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. However, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. The end products from the waste treatments plants include recycled products, clean water and safe, biodegradable products. The treatment process for the waste depends on the source and type of waste. Wastewater is common in most process including in homes and industries. There are different stages of the wastewater treatment process.
Most homes treat their water using the septic system 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 waste water treatment plants for use in large residential estates and factories. 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. Engineers at the manufacturers will oversee the project from its design stage to monitoring and maintenance works. These are a sophisticated process that requires large investments. These systems remove quality clean water and thus used at commercial levels.
The wastewater treatment plants involve three main stages. 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. 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 taken to the second stage of treatment known as the secondary stage of 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. More than 80% of impurities in the water are removed at this stage. The water that is released into the environment at this stage is not harmful.
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. There is application of different water treatment chemicals to make it 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.
