The sewage treatment plant in Dubai is one of the main areas of wastewater treatment in Dubai. It has been significantly expanded in recent years. We explore the process of wastewater treatment and its challenges and The capital has declared its intention to reuse all wastewater by 2020, with the through to a sewage treatment plant in Dubai.

The sewage treatment plant in Dubai

The wastewater that flows into the existing sewage treatment plant in Dubai is 1/4th of Dubai's daily flow of 600 million liters. The overall effluent discharge capacity of the plant is about 60 million liters per day. The treatment of wastewater is the first stage of wastewater treatment. The treated water can be used for non-potable purposes such as industrial and commercial purposes. The wastewater is transferred to the plant's pumping station through an underground pipeline. It travels through a series of hydraulically-powered processes until it reaches the incineration unit. In the incineration process, the water is transferred through a very large gas burner (in this case the waste gas). This heat is then used for the process.

The history of sewage treatment plants

In the past, we were directly connected to the sea. Our sewage was not treated in the sea. The sea is now polluted with sewage and bacteria, which enters the sea through the coastline and is heavily diluted with fresh water. These bacteria produce a lot of nitrogen, which can cause problems with the water system. Some of the discharge from the wastewater treatment plants contain waste energy. The plant works to recycle this energy for reuse in cooling towers. In the 1960s, the Emirates started to experience serious problems with rapid development and the growth of population. This put pressure on the sewage treatment plant. The wastewater was not properly treated.

The process of sewage treatment

The process of sewage treatment begins with an infiltration process to allow water from the body to pass through the system. The recycled water is called "non-potable" or sewerage water. The first wastewater is called "sewage" water, which is the water that flows into the sewage treatment plant, after exiting the stormwater drain and coming in contact with the sewage system, due to water runoff from a house or a drain. It is used to power the plants' motors and systems, to flush the wastewater, to flush the toilets, to wash the cars, and to do the cleaning of the vehicles. It is also used for cooling, lighting, air conditioning, heating of the building, and for other domestic activities.

Challenges of sewage treatment plants

Not all wastewater produced by the population is adequately treated. The problem with these communities is that they do not have easy access to the sewerage system. It is possible for all the wastewater from the end of the water supply chain (i.e. from the municipality, consumers, and disposal of the wastewater into the sewer system) to reach the sewers. However, some of the treatment plants are unable to handle the wastewater so far removed from the sewers. Some of the pollutants such as organic waste or sewage sludge can cause blockages and water quality can decrease when they are disposed of in the sewer system. Another challenge is that the population does not contribute to the maintenance of the infrastructure of the water and sewage system.

The future of sewage treatment plants

New water-efficient sewer systems "In the 1980s, Dubai was running 40 million gallons of sewage a day. With 30 percent of the population living in public housing, high-rise buildings, factories, shops, and office blocks, the city's sewage was regularly spilling over into the Persian Gulf, exposing over a quarter of Dubai's coastline to the possibility of sewage pollution. In the 1990s, Dubai's municipal government made a plan to minimize the number of homes using the sewer system by half and was able to do so by building a smart sewer network.

Conclusion

The Highways Department in Dubai has set out a strategic framework for installing pump stations and is establishing their capacity, which has greatly increased the size of the DEDP project. Some of the pumps installed are placed on average 20 kilometers away from residential areas to prevent noise and avoid any possible damage to people and buildings. The DEDP has recently decided to install pump stations in the city. Currently, there are 42 pump stations in Dubai. To build each of the pump stations, a minimum of five are required to carry out the construction of the water and sewer network in Dubai. This creates a significant bottleneck due to the lack of pipelines in the areas where these pumps will be placed.
