- Aquatech awarded a major desalination contract for India’s First Ultra Mega Power Project
Aquatech has been awarded a contract to Design, Build, and Operate a Seawater desalination plant for India’s First Ultra Mega Power Project (UMPP) at Mundra in Coastal Gujarat. The 4,000 MW coal fired plant is owned by Coastal Gujarat Power Limited (CGPL), a Tata Power group company. Tata Power is India’s largest private sector power utility with an installed generation capacity of over 2300 MW. THE CGPL UMPP, awarded on a 20 year BOOT basis, will be India’s first private sector power project using supercritical boiler technology; and is expected to be the most energy efficient plant in the country.
CGPL will draw seawater from along the Mundra coast for various utilities and for their main boiler. For this very critical desalination application, CGPL has placed their trust in Aquatech for execution of this seawater Desalination plant, which is based on Reverse Osmosis (RO) Technology. TCE Consulting Engineers, Bangalore, are the owner’s consultants for this project.
One of the larger desalination projects to come up in India in recent years, the plant, utilizing Sea Water Reverse Osmosis (SWRO) technology, will produce 25,200 m3/day of desalinated water for various end user applications. A part of desalinated water will further be treated through a Brackish Water Reverse Osmosis (BWRO) system and ion exchange to mal4 high purity water for boiler makeup.
The system pretreatment includes lamella clarifiers followed by two-stage pressure filtration. The SWRO system consists of 4 Streams of SWRO banks followed by 2 banks of BWRO. The plant will be designed for 40% permeate recovery on a difficult feed water, with Total Dissolved Solids (TDS) content varying from 42000 mg/I to 46000 mg/I and a maximum feed water temperature of 35°C. This has however not deterred Aquatech from committing stringent treated water quality of less than 450 mg/I TDS levels at the outlet of SWRO and 5-7 mg/I TDS levels at the outlet of BWRO Systems.
Aquatech will be supplying this project on Engineering Procurement & Construction (EPC) basis along with an O&M contract, and is targeting to produce 12,000 m3/Day of treated water by November 2009 and to commission the entire SWRO plant by mid 2010.
Aquatech has won this project against tough competition from renowned international bidders, on the basis of its strength in technology and innovation, a track record of performance, quality, and sustained growth.
Mr. Devesh Sharma, Managing Director, Aquatech Eastern, stated, “Winning this prestigious project further validates Aquatech’s position as leader in desalination and will provide a platform to the company for future EPC business in this space.”
- NHAI constructing dustbins along GST Road
The National Highways Authority of India has started constructing dustbins along the Grand Southern Trunk Road (National Highway 45) as part of ensuring the ‘road traffic worthiness’ of the arterial road. The yellow dustbins have been installed all along GST Road between Tambaram and Chengalpattu as part of the NHAI’s steps to keep the carriageways and service lines free from litter. NHAI engineers told that ever since improvement works on GST Road (NH 45 connecting Chennai and Dindigul) commenced as part of the Golden Quadrilateral project under the National Highways Development Project, they were attaching a lot of importance to improving the quality of amenities for both motorists and people living in localities adjacent this stretch. NHAI engineers said they had been urging both urban and rural bodies to keep the main carriage ways free of litter and mess. However, both the traveling section –– be it those on private or public transport and local residents –– continued to dump huge quantities of refuse on the arterial roads. Hence, the contractor entrusted with the task of carrying out improvement works on GST Road was also asked to make sure that litter in any form did not come in they way of smooth flow of traffic. NHAI, the engineers said, had given the job of widening and improvement works on GST Road to private infrastructure major GMR on a Build–Operate-Transfer basis. The private firm, the engineers said, was building the dustbins as part of the mandatory contract with NHAI.
