Stages of Waste Water Treatment Process.
Industrial and domestic processes lead to various forms of waste including 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 treatment process for the waste depends on the source and type of waste. Wastewater is common in most process including in homes and industries. The wastewater treatment process involves various stages.
Wastewater from homes is normally treated in septic systems. 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 that can help you design and manufacture a 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. The output of the system is high grade usable water hence is used at commercial levels.
The water treatment process ahs three main phases. water flows through pipes by means of pumping or gravitational force. In these reservoirs, there is removal of floating and suspending solids. The process involves use of centrifugal force. The process can remove the 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. At this level, the remaining biodegradable and suspending particles are provided as food to organisms such as fish. The organisms consume the biodegradable components in the water and remove the phosphates and nitrates 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.
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. 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 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.
