Stages of Waste Water Treatment Process.
Industrial and domestic processes lead to various forms of waste including water, solids and gases. These types of wastes are directed into the environment and cab e hazardous. 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 processes involved in the treatment of these wastes differs depending on the source and the 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 Though the septic system is simple, it should always remain 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. The process needs to be carried out per the circumstances. The manufacturers have engineers who handle the project since its inception to monitoring and maintenance works. These types of plants are huge capital investments and are also sophisticated. These systems remove quality clean water and thus used at commercial levels.
There are three main stages in the water treatment process. Water flows to reservoirs either by pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. The process involves use of centrifugal force. The stage removes about 60% of the suspended solids. Removal of solids can be increased through addition of chemicals. 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. Water passed through his phase is not hazardous to the environment.
However, to make the water pure, the third stage is incorporated. It is referred to as the tertiary stage and water can be used for a wide range 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 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.
