Waste Water Treatment Processes
Industrial and domestic processes lead to various forms of waste including water, solids and gases. The wastes are absorbed into the environment and cab harmful, 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 choice of treatment plant is dependent 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.
Wastewater from homes is normally treated in septic systems. The septic system is simple and should always be functional. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume 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. A project plan is made according to the unique circumstances surrounding it. 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. The water released from these systems are quality clean and therefore used at commercial levels.
There are three main stages in the water treatment process. water flows through pipes by means of pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. This process happens in the presence of centrifugal force. The stage removes about 60% of the suspended solids. Removal of solids can be increased through addition of chemicals. water is then pumped to the secondary stage which is referred to as the organic stage. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. The organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients 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. 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. Chlorine is used by several firms though it have become a subject of debate in the recent.
When water is being pumped into the treatment plant; it 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.
