There are however wastewater treatment plants for use in high factories and residential estates. 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 are a sophisticated process that requires large investments. The water released from these systems are quality clean and therefore used at commercial levels.
The wastewater treatment plants involve three main stages. water flows through pipes by means of pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. This process happens in the presence 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 this phase, the remaining biodegradable particles are provided as food to controlled organism 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. 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. 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. 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 that is producing water containing chemicals should remove these chemicals by having a treatment plant at their base.
