Steps Undergone During Green Wastewater Treatment

By Anna Turner


Very bad odor occurs as a result of waste water that is left unattended to. This has bad effect to the organisms living around and even those present in it. Green wastewater treatment is very useful as it helps in converting the water that was originally a waste into a form that can be used by human being and other organisms. This is a type of environment conservation and it is of benefit to the organisms living around and in it.

Too much accumulation of the organic matter limits the amount of the oxygen entering to the interior meaning that organisms underneath are not likely to carry out the respiration process which is essential in energy production. It is therefore very important to treat it so as to conserve those that live within it.

There is very bad odor produced which makes the people and other organisms living around it find life uncomfortable. Upon noticing such odor, it vividly shows the need of cleaning it. Some of the contaminants may be toxic to phytoplankton and may end up killing the organisms, due to starvation after there is no more phytoplankton.

Before commencing the process of water treatment, it is very essential to screen the water as it enters the place to be treated. One needs to be very careful during this stage otherwise the treatment equipment may be destroyed if the large debris not properly eliminated. Another importance of removing the debris is avoiding the blockage of the pipes that may occur if carelessly done.

It is very essential to pass it through the grit chamber as it helps in the removal of grit. The speed during this stage should be high to ensure that the organic sediments do not settle. The high speed also prevents aerates from mixing. Some of the plants may skip this stage but it becomes important for quality treatment.

Sewage components are usually separated in the sedimentation tank. This makes the liquid clearer than before. At this stage the sludge is separated and removed for the next step. Together with the scum are directed to the next point which is processing unit. Scum is composed of the oils and the soap components.

The next is the filtration process where iron and the calcium are eliminated. This process is done by passing the liquid through the sand debris. At the end of this stage the water is very clear. However, it still contains other contaminants such as the bacteria which make it harmful for consumption. If need be, more filtering is done. Bacteria are killed through chlorination.

In many cases the chlorine remaining in the water is treated with other chemicals with the intention of neutralizing it. The cleansed waste water is then disposed to various destinations. Some of it may be used for the irrigation and other domestic purposes. In other cases the cleaned water is disposed to the rivers and even the oceans. It is now considered clean and has no harm to the organisms.
