If things go as planned, the city of Jamshedpur will soon become a shining example of waste treatment and environmental conservation in India. The city administration is setting up an enormous waste water treatment plant that will purify all of the city’s effluents and supply recycled water for industrial purposes. This will not only prevent the sewerage from entering nearby water bodies, but also create an additional source of water for the industries.
Initiative by JUSCO:
The Jamshedpur Utilities and Services Company (JUSCO), a Tata Steel subsidiary, has undertaken the task of building a water treatment plant at Bara. This plant will have a capacity of treating upto 30 million litres of sewerage water per day. Together with the existing plant located at Bistupur, the whole system will be able to treat upto 40 million litres of sewerage per day, effectively recycling the entire sewerage discharge of Jamshedpur. Note that the industrial city ranks 4th in terms of India’s per capita water consumption.
Use of the ZLD technology:
The recycling plants will use the technology called ZLD (Zero Liquid Discharge) which employs the most advanced wastewater treatment technologies to purify and recycle virtually all of the wastewater produced. This is the process which is followed:
1. The waste water is pre-treated with ultra-filtration and reverse osmosis processes, which help in concentrating the dissolved solids.
2. The water is then passed through an evaporation stage where the dissolved solids precipitate down and are removed.
3. The water vapour from evaporation is condensed and returned to the process as purified water.
The project is expected to get completed by early 2017. This is not the first eco-friendly project undertaken by JUSCO. In 2015, it had created ripples by using plastic waste to construct roads in Jamshedpur. Such initiatives by the company are truly remarkable and worthy of emulation nationwide.
The Logical Indian appreciates the efforts of JUSCO to make Jamshedpur India’s first Zero Sewerage Discharge city and encourages other city administrations to take up similar projects in the interest of the environment.
