Waste Water Treatment Processes
There is release of variety of waste from both domestic and industrial such as water, solids and gases. These types of wastes are directed into the environment and cab e hazardous. However, taking these wastes through treatment process reduces harm made to the environment. 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.
Most homes treat their water using the septic system The septic system is not complicated but should always be functional mode. Nevertheless, septic systems that serve several homes are more 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. 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 are a sophisticated process that requires large investments. These systems remove quality clean water and thus 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. The water is then directed to the second phase also known as secondary stage or organic stage. In this phase, the remaining biodegradable particles are provided as food to controlled 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. More than 80% of impurities in the water are removed at this stage. The water that is released into the environment at this stage is not harmful.
The third stage is however introduced to make the water pure. The phase is referred as the tertiary level and the water released is usable for a variety of uses. Various chemicals are applied to remove the impurities and ensure that it is safe. 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 individual factory releasing such waters should take individual responsibility by establishing a treatment plant at their base before releasing such water.
