Create electric lighting from toilet wastewater

The project Creating lighting electricity from toilet wastewater of two students of Duy Tan University, Da Nang won the first prize in the Green Solution Competition for the city.

Utilizing waste water from human hygiene activities to generate electricity to clean the toilet - This is the project that won the first prize in the Green Solution Competition for the City - Go green in the city 2017.

The project has a strange name: 'Toilet mini generator' - 'Mini generator and battery generating urine', is the study of Nguyen Cong Tin and Nguyen Thi Thanh - Duy Tan University student, Da Nang under the guidance of Dr. Tran Nhat Tan - School lecturer.

According to a survey of the two of you, at present many public toilets in the city have a constant number of people going in and out but the lighting system is very limited, causing inconvenience to users, especially at night. .

Besides, the amount of wastewater from human hygiene activities (mainly urine) is quite large, on average each public toilet uses 8-9 m3 / month of water, for households. Many families can get up to 15m 3 / month. This amount of wastewater is a potential energy source for running small generators.

'Taking advantage of this energy source to light electric lights on the spot will create a circulating, economical and environmentally friendly system , ' Nguyen Cong Tin said.

With the idea of ​​installing a motor and propeller in the water pipe, the motor will create an electric current that can be used for lighting in public toilets, the two of you have started working on the project under support. of teachers and school.

This mini generator can be installed in many types of faucets, sinks, . and many other areas outside the toilet. The machine uses urine as a main material to generate electricity.

The battery from this urine operates in the form of an electrochemical battery, the electricity generated from it will be stored for lighting in public places without a complete electric light system.

Since urine is a regular source of raw materials in toilets, it is constantly renewed so users do not have to worry about running out of battery when the machine is operating.

Currently, the project is still being completed by Tin and Thanh before being widely deployed. The two of you also hope, the product will be chosen by cities in the near future.

The 'Toilet mini generator' project won the first prize at the Go green in the city 2017 Contest.

According to the jury of the Go green in the city 2017 competition , the project is a reasonable solution to save energy, suitable for the trend of green - clean - beautiful development in urban areas.

After winning the first prize in the country at the Go green in the city 2017 competition in Ho Chi Minh City, Tin and Thanh's group will be the only representative of Vietnam to compete in Go green in the city in East Asia. , held in July 2017.

Go green in the city is a competition organized by the global energy group Schneider Electric - based in Rueil-Malmaison (France). So far, the competition has been held 7 times with the participation of tens of thousands of students from 170 countries and territories worldwide.

The goal of the competition is to find and develop effective and innovative energy use solutions in smart cities; educate and build awareness for the young generation about the need for smart energy management.
