Waste Water Treatment Processes
There is release of variety of waste from both domestic and industrial such as 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 end products of the waste treatment plants includes clean water, harmless biodegradable and recycled 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 Though the septic system is simple, it should always remain functional. However, septic systems serving large populations are complex since they have to absorb lots 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. 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 process can remove the about 60% of the suspended solids. 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. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. The organism in the water eat the food particles in the water remove the phosphate and nitrates nutrients 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. The water may be treated using various chemicals to ensure its safety. Chlorine is used to purify the water though it has been disputed in the recent times.
Water pumped to the 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.
