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, The harm made to the environment can, however, be reduced by taking waste through treatment plants. The waste treatment process produces harmless products such as water, recycled products and harmless, 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.
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. There are however wastewater treatment plants for use in high factories and residential estates. There are manufacturers of wastewater treatment plants and can help with the design and construction of wastewater treatment plant. A project plan is made according to the unique circumstances surrounding it. The manufacturers have engineers who handle the project since its inception to monitoring and maintenance works. These systems are complex and require large capital outlay. 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. Centrifugal force is applied at this stage. About 60% of solids will be removed at this stage. 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. In the second stage, the remaining biodegradable and suspending articles are given as food to organism such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates in the water. This stage removes over 80% f the water impurities. Water released to the environment at this stage is not harmful.
water is however made pure by
taking it to the third stage. It is referred to as the tertiary stage and water can be used for a wide range of uses. There is application of different water treatment chemicals to make it safe. Chlorine is used to purify the water though it has been disputed in the recent times.
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.
