Why Water Aren’t As Bad As You Think

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, if the wastes are taken through treatment plants, the amount of harm done to the environment could be minimal. 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. 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. Septic systems serving a larger number of people are more complex since they have to absorb a higher volume 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 and can help with the design and construction of wastewater treatment plant. 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 wastewater treatment plants involve three main stages. Water flows through pipes either by pumping or gravitational force to large reservoirs. In the reservoirs, there is separation of floating and suspending solids from the water. Centrifugal force is applied at this stage. The stage removes 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. In the second stage, the remaining biodegradable and suspending articles are given as food to 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. This stage removes over 80% f the water impurities. 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. This phase is known as tertiary level, and the water released here can be used for different purposes. There is application of different water treatment chemicals to make it 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.
