In India, the need to treat wastewater is a goal set by municipal authorities everywhere. But, to comply to the set goals, the task is daunting. It goes without saying that if the country could deploy adequate technology to treat water, it could significantly expand its water supply and better water means.
Council’s lead partner, Xylem is supplying advanced wastewater treatment technology to the first-ever sewage treatment plant in Sehore, Madhya Pradesh. The new plant, which is expected to be operational by August 2018, is being developed to accommodate rapid industrial growth in Sehore. The plant will play an important role in improving the environment, since a 2015 study found that river stretches in the Madhya Pradesh region had some of the highest rates of pollution.
Nearly 1,00,000 people in the city of Sehore will be benefited, further enriching the quality of life in the region. Xylem’s contract includes designing the treatment process, supplying and installing all treatment technology, and commissioning the plant. The treatment technology will include the Sanitaire ICEAS Sequential Batch Reactor (SBR) system, diffusers, decanters, and control and instrumentation technology.
Enhancing water quality
Xylem will provide wastewater treatment expertise and technology, including a Sanitaire ICEAS Advanced SBR system. The system will support the treatment of 12 million litres of wastewater per day, and meet wastewater discharge quality standards set by the Madhya Pradesh Pollution Control Board.
Xylem’s Sanitaire ICEAS Advanced SBR is a continuous flow biological treatment system that provides multiple advantages versus conventional activated sludge and other SBRs by bringing together process, aeration, decanting, and control in a single treatment tank. It is fully automated and includes a completely integrated process design consisting of the aeration system, blowers, pumps, mixers, effluent decanters, monitoring and control equipment, and a comprehensive process control system.
The ICEAS Advanced SBR is designed to reduce complexity of operation. Unlike conventional activated sludge plants, there is no need for primary or secondary settlement tanks or return sludge pumps. All treatment is done in a single basin. Continuous inflow distributes variations in flows and loads evenly across all basins – simplifying day-to-day operations and operational changes, as well as accommodating single basin operation for low flow and maintenance conditions.
The intelligently-designed process control system with simple, intuitive, time-based control and trending capability provides a full system overview, making it easy to optimize plant performance, predict maintenance and reduce operating costs – taking the complexity out of SBRs.
Xylem’s ICEAS Advanced SBR can handle flows from 100 m3/day to 300,000 m3/day. Thanks to the unique basin design and actively controlled decanter, the ICEAS Advanced SBR can be designed to accommodate up to six times average daily flow while assuring high effluent quality across the entire flow range. The ICEAS Advanced SBR process can also be designed to remove nitrogen and phosphorus from wastewater through biological nutrient removal (BNR) processes.
