1. Smart system for Waste water treatment management
Shaimaa Ahmed

2. One of the main challenging in wastewater treatment is the mixing between Gray water and black water, because the size of black water increases thus time, cost & energy required for treatment.
Gray water is all of the wastewater that comes from washer, sinks, bathtub or shower.
black water is water coming from the toilets

3. The new management system divide the process of collecting wastewater to two systems or two pipe system, where one collects gray water and the other collect black water.

5. Gray water usage
Part of Gray water can be recycled in the basement of the building and reused in providing water for toilets water
The recycling unit in the basin depends on the geothermal energy to vapor gray water.
Vapors can be collected and produce fresh water. (this will take time so we will use part of the gray water)

6. a Gray water going to the treatment unit
Treated water that is going to be reused

7. Other usages Swage water It can be used for house garden irrigation
For housing areas, the rest of gray water can be collected and treated and then reused in public garden.
In addition, gray water is more cleaner than the black water, thus gray water treatment is easier and safer to be used in agriculture activities .

8. GIS/GPS usages
GIS/GPS system is required for water quality assurance and management.
It is important to have devices in main treatment units to conduct regular sampling for both gray and black water.
These devices collect the main data about water parameters in the wastewater treatment system.

9. These devices are linked with online GIS system that enable health and city officers to monitor the treatment process and to fix any problem before it accumulate.

10. GPS system is essential to monitor any water leakage
GPS system is essential to monitor any water leakage. In addition, it is a need to estimate the water quantity required to be reused in each building, gardens and public gardens.
Only part of the gray water is going to be reused in buildings.

11. black water treatment
The treatment units are allocated outside the city and the main energy source are solar energy generated by solar plants or courtyards units (another idea that was posted by me)
The whole treatment process can be done using Courtyard wind energy and thermal energy magnified by lenses which is installed in domes

12. Example to the system Vault contain lenses That magnifies solar rays

13. Individual share
GIS and GPS system also can calculate how much clean water gallons is consumed by each individual ( average value based on the house water system)
GIS/GPS system located in the black water treatment also can calculate average water waste is produced and cost of energy ..etc
Based on that the system in later phases can limit the average individual consumptions

14. How?
Each bathroom and kitchen can supply a certain amount of water and this system is controlled by GIS/GPS system.
This is for environmental needs and if water is needed, an online system can facilitate that and the family has to pay more money to get more water.

15. Using Red Sea’s mangroves as wastewater treatment facility
Some may argue that reusing treated gray water is not healthy and it should be released into the sea again. However, this also may affect marine life in the sea.
I thought that using Red Sea’s mangroves in treating gray water may be an environmental friendly solution.
In the desert, it is possible to constructed mangrove wetland system as a secondary municipal wastewater process.

16. Mangrove usage
Mangrove usage may be limited to gray water or to black water too. The decision is based on
Environmental Impact assessment because this was not implemented before in the MENA desert, and the effect of the treatment on mangrove is not clear either. Thus field experiments should be conducted before implementing this idea on large scale.

17. Next?
Water resulting from mangrove treament unit can go through several sand filter and then it can feed another constructed mangrove area for shrimp farming or agriculture.

18. A published study can be found on
and
and Beyond the desert: Exploring Saudi Arabia’s mangroves

19. Advantages Less clean water usage in houses and in garden irrigation
Less time, cost, energy and effort for black water treatment.
More control and easier management because of sensing devices attached to treatment units
Healthier environment because less black water equals less risk for leakage and less health risk

20. Challenges
This system has to be implemented gradually in order to overcome any challenges such as People culture. Cost. GIS/GPS problems.
