UAE’s Largest Sewage Treatment Plant Delivered Ahead of Schedule

Whether we are chatting about a natural or chemical treatment system, large or small basins, or simple or sophisticated installations, water purification has the same purpose. Wastewater treatment consists of reducing the pollution present in the water. This pollution results from human activities: through domestic use or in industrial networks. Wastewater treatment is used to ensure its quality. Indeed, the treated water, considered “clean water,” will be used in human activities or discharged into the natural environment. These environments can be of different natures: river, sea, lake, etc. It is important not to reject materials that are harmful to species that live in the natural environment. These discharges are regulated by legislation and prefectural orders.

Are we aiming for quality comparable to drinking water?

The treatment quality of a station will be highly dependent on the environment in which the treated water will be discharged. There are indeed very sensitive environments, such as small rivers, that require very thorough purification, aiming for almost perfect water quality. On the other hand, discharges can be collected in common networks, to be directed later to municipal stations, which will finish the treatment. In this case, the initial treatment does not need to be too extensive.

Thus, the purpose of the treatment is not to make the water drinkable but to get rid of its pollutants (waste), such as suspended (solid) or dissolved matter, of a chemical, natural or organic nature (such as stools, etc.). For this, a wastewater treatment plant can use various combined techniques and technologies such as activated sludge treatment (biological), secondary and primary treatment, etc. The use of industrial gases (mainly nitrogen, oxygen, and CO2) is interesting and even necessary in certain sanitation stages in wastewater treatment plants. In particular, we can cite the safety inserting of sludge with nitrogen, doping, and therefore, the extension of the capacity of a pure oxygen station or the adjustment of the pH of wastewater with CO2.Toxic micropollutants, such as medicines and personal care products, are the primary source of micropollutant contamination from sewage treatment plants (PPCPs)

Drinking water has. A valuable resource

Water is an abundant resource on Earth, as the seas and oceans cover nearly 71% of its surface. This represents approximately 97% of all the water on the planet. However, this water is salty. The remaining 3% is made up of freshwater, but glaciers and ice caps account for almost 80%. Only the rest is accessible for human consumption, which makes fresh water a rare resource, available in rivers, reservoirs (lakes), and groundwater.

In addition, freshwater reserves are very unevenly distributed on the planet. The cold, temperate, and equatorial zones are, on the whole, quite well provided. On the other hand, the lack of fresh water is evident in the equatorial regions, including, of course, the desert areas. Additionally, then two billion citizens in the world are affected by difficulties in accessing drinking water (less than 5 L per person per day).

Production and treatment of drinking water

Freshwater drawn from nature is rarely drinkable as it is. It is often necessary to subject it to several treatments in order to clean it up. The purpose is, in particular, to eliminate the presence of germs, pollutants, etc., which would present a danger to health. The UAE largest sewage treatment plant, REKAS, offers tailored solutions for all of your water treatment requirements.
