Industrial waste water treatment

Industrial Waste water Treatment Industrial Waste water Treatment Industrial water is different from the sewage waste water and the sea water and thus requires special processes to be treated for the use in the environment or for the drinking purposes. As given, the industrial water contains oil residues, harmful chemicals and has a pH of 10. The pH 10 means that the chemical composition of water is of Basic nature. On the other hand, the oil residues remain heterogeneously mixed with water and can be skimmed off the surface of water through skimming mechanism.
The industrial waste water treatment process include the oil skimming process, treatment of reacted ions and then utilizing the biological indicators for determining, if the water is fit for drinking or should it be allows to be penetrated into the environment. The oil or grease are lighter than water and can be collected over the surface of the water through simple process of skimming.
After undergoing research, it is clear that the utilization of the membrane technology for the treatment of industrial water is not suitable as membranes are much sensitive to the chemicals. Thus, vapour compression processes are perfect for treating the industrial water. as, mechanical vapour compression produces water with the highest quality and is more energy efficient as compared to the thermal vapour compression, it is suitable for the industrial water treatment of the given composition. As, the water has a pH showing the more concentration of basic ions, it is important to acid acidic ions to precipitate the basic ions.
Oxygen and nitrosamines are added to convert the NH3 into NO2 that is good for the plants or can be extracted easily from water through next process. The Phenols can be removed by utilizing the active carbons and UV oxidation. The treatment of the thio-cyanate can be controlled by utilizing alkaline chlorination and ozonation. NaNO2 can be removed by utilizing the sulfamic acid, which reduces the NaNO2 to nitrogen gas that can be collected or released to the atmosphere. Bacteria can be added to the water to eat COD and produce bio gas that can be used to produce power for the plant. Calcium or aluminum ions can be added to reduce the amount of PO4 in waste water.
The next step would be the purification of industrial waste water through the mechanical vapour compression. Mechanical vapour compression gives the same purification as that of the distilled water and utilized the similar procedure for the purification. There is essential to utilize the high density platinum steel in the compression chamber that would restrict the corrosion or the rust odour in the water.

The next step is the utilization of the biological indicators to evaluate whether is fit for drinking or can it be allowed to penetrate into the environment. The important biological indicators are biological algae, bacteria, etc. These biological indicators are sensitive to the water conditions and are unable to remain alive in bad water or water with higher concentration of harmful chemicals. The examination is time taking.
