Stages of Waste Water Treatment Process.

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, However, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. 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 a produced in typical all process including homes and industries. The wastewater treatment process is carried out in three phases.

Wastewater from homes is normally treated in septic systems. Though the septic system is simple, it should always remain functional. 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 assist you in design and construction of wastewater treatment plants. They will design the plan according to the project specific needs. 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 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 to reservoirs either by pumping or gravitational force. There is removal of floating and suspending solids in the reservoirs. The process involves use 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. 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. This stage removes over 80% f the water impurities. The water that is released into the environment at this stage is not harmful.

However, to make the water pure, the third stage is incorporated. 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 by several firms though it have become a subject of debate in the recent.

Water pumped into the wastewater 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.
