Waste Water Treatment Processes
Industrial and domestic processes lead to various forms of waste including water, solids and gases. These wastes are absorbed into the environment and can be dangerous. 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 processes involved in the treatment of these wastes differs depending on the source and the type of waste. Wastewater is a produced in typical all process including 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. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume 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. 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. These systems remove quality clean water and thus used at commercial levels.
The wastewater treatment plants involve three main stages. Water flows through pipes either by pumping or gravitational force to large reservoirs. There is removal of floating and suspending solids in the reservoirs. This process happens in the presence of centrifugal force. About 60% of solids will be removed at this stage. Removal of solids can be increased through addition of chemicals. The water is taken to the second stage of treatment known as the secondary stage of organic stage. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. These organisms consume the biodegradable components in the water and remove the nutrients such as phosphorus and nitrogen present. More than 80% of impurities in the water are removed at this stage. Water released to 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. 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 responsible for releasing water with industrial chemical should take responsibility by establishing a treatment plant at their base to remove the chemicals.
