Smart parallel water

Water treatment which Polymer to remove the dye and then multimedia filtration containing activated carbon to get rid of most suspended solids merged with Arduino helps the flow of water.

An unbearable pressing water crisis is consistently and continuously plaguing Egypt. The water crisis is due to the unmeetable increasing demand on water and crops. Alongside other factors, water scarcity hinders the country’s development. This project solved this fatal scarcity by providing an upgraded water treatment method. Based on the idea of simple distillation, a solar still device was constructed to purify salty water. The introduced device uses chemicals, physical processes and Arduino to treat textile wastewater. Water produced by this device was desired to be used in the industry again to help water consumption.

Our globe is 70% covered by water; therefore, it is natural to assume that there will always be a bountiful supply of fresh water, which we need to drink, bathe with, and irrigate our farm areas, which is exceedingly scarce. Fresh water makes up only 3% of the world's total water supply, and two-thirds of that amount is hidden in frozen glaciers or inaccessible to humans in other ways. So, we must treat some polluted wastewater to reuse it to fill the need for freshwater for many domestic uses.

The treatment is two staged processes. The water passes through a chemical treatment and a physical one.

The chemical process

The first process is coagulation. Coagulation is used to large the pollutant particles by attracting and neutralizing them, as the chemicals used for the process have the opposite charge of the pollutants. As the pollutant particles get more prominent, it is easy to remove them by a physical process. Textile wastewater contains a high pH value and high dissolved and suspended solids concentration. We use chitosan(C56H103N9O39) and hydrochloric acid (HCl) as a polymer to remove these undesired pollutants in the sample. Final HCl and chitosan concentrations in the latter solution were 0.5 M and 1.0% (w/v), respectively. As the polymer attracts the particles responsible for the high TDS and pH values, the new larger particles are either precepted or suspended in the water.

The physical process  The second process is multimedia filtration. As the water passes through the filter, it holds the large particles of the passing water. It comes as a complementing process for the coagulation process. The multimedia filtration is ordered from the height porosity to the lowest in three layers. Porosity is the void spaces in a material. The first layer is the gravel, it keeps the large particles enough to be held. The second layer is activated carbon, it contributes to removing the particles responsible for the undesired color of the water sample. The third layer is the sand, which is used to complete the filtration process by holding the smallest particles of the water after passing through the coagulation process.

Our solution addresses the people who lack a clean source of water to use and by treating wasted water we can serve them a clean start to use to improve their health.

I am the leader and recorder and got the experience and knowledge to do this while working in extracurricular activities.

Ziad is the researcher and the writer and got enough skills to do this from the competition and training he had participated in.

Badr is the software man who did all the software work and wrote the Arduino codes.

So, according to our search and research papers we read, the tests we did, and the data collected from the analysis of the results, we got a solution to treat our polluted sample from the dye and other suspended solids through polymer and multimedia filtration.

By solving this problem, we solved many related problems such as increasing Egypt's industrial and agricultural basis, addressing and reducing pollution fouling on air, water and soil, improving the use of arid areas and working to eradicate public health. Using Arduino with the chitosan and multimedia filtration treated our sample from different pollutants.

By looking at all of this, we had achieved the design requirement we have considered and overcame the challenge that faced us this term. Our polluted water has a pH of 8.4 and a TDS of 680 ppm but after treatment, both pH and TDS decreased to 6.7 and 100 ppm respectively.

As we use Arduino with simple water treatment processes. It can reduce the expected errors and increase efficiency.

We want to apply our project to all the desired factories.

Arduino is used to sense its environment by receiving inputs and readings and interact with us by controlling lights, motors, etc... We started with coding by downloading the libraries and organizing the output pins in the code, then we started in the loop that we put the time that each motor will work according to each process. In the first process, we get the water we want to filter and put the water level sensor on 150ml. We made a delay of 2sec, then the second motor transferred the amount of the mixture of HCL and chitosan and waited 5min while stirring the water sample to mix it with the polymer. The third pumper work to take all the mixture to the multimedia filtration to hold the last treatment process. This process has a delay of 5min to provide enough time until the process is completed. The fourth motor will then pump the treated water to the last container to be used again in the textile industry.

We haven't applied it yet, but we can conserve clean water to serve 2 million people in the next two years.

The cost of the energy we need to use in our system.

We work on our own. We haven't worked with any organizations.

We didn't have time to do one.

From the factories that will buy the system of treatment.
