TISS (Toshiba Infrastructure Systems & Solutions Corporation) has signed a contract with Larsen & Toubro for three ozone generators at the Chandrawal Water Treatment Plant in Delhi, India, which is being built by the Delhi Jal Board. This is one of India’s most expansive ozonation systems for a water treatment plant.
The project is part of the Delhi Water Supply Improvement Project, which is funded by the Japan International Cooperation Agency.
The JICA-assisted 477 mld water treatment plant at Chandrawal, which is being built by L&T to replace existing water treatment plants, will be equipped with Toshiba’s ozonation systems, which will have three ozone generators each with a capacity of 31 kg per hour.
Dechlorination, deodorization, inactivation of viruses and bacteria, oxidation of organic and inorganic substances, and a reduction in trihalomethane formation during chlorination are all applications of ozone. Furthermore, because ozone simply reverts to oxygen after use, it has little negative impact on the environment.
Ozone treatment is widely used in large water treatment plants in Japan, particularly in urban areas. In the 1970s, Toshiba began developing and delivering ozonation systems. Toshiba has delivered over 130 ozonation systems for over 100 projects since then. Toshiba has secured this contract with L&T as a result of its strong track record.
