Tirupur, the textile knitwear hub of India discharges about 100 MLD of dyestuff effluents with high salt content and multi colored effluents from as early as 1990s. It flanks and pollutes the Noyyal river course rendering it as a virtual effluent course as rainfall is hardly for 15 days only in a year.

When the city of American Falls, Idaho (USA) was looking to replace an existing chlorination system for the disinfection of municipal wastewater, a primary concern was for a disinfection system that eliminated the dangerous chemical byproducts of the chlorination process. To meet these demands, the municipality turned to ITT for the installation of a disinfection system using WEDECO ultraviolet technology.

The Water Services Corporation in Malta is one example of a forward-looking operator of a seawater reverse osmosis seeking to ensure the production of high quality drinking at an affordable price.

This case study reports on the application of fractional electrodeionization (FEDI) in the production of high purity deionized water. The advantages of this two-stage dual voltage technology over conventional electrodeionization (EDI) are discussed, including better quality of treated water, ability to handle feed water fluctuations, optimized power consumption, and quick on-site regeneration of media. Opening data and experience from one power plant is presented.

Treatment of Karnaphuli Paper Mills effluent was carried out by coagulation precipitation method.

Nalco 3D TRASAR for sugar automation technology was designed to help sugar and cogeneration power plants to reduce cooling towers and boilers fresh water usage.

In the present study, the main aim is to identify an appropriate RWH structure for a large scale automobile industry in India. The first step in designing any RWH structure is to determine the volume of water to be stored. In this case, it was achieved using four methods namely mass balance, Ripple diagram, analytical and sequent peak algorithm methods.

Because of a GIS work, Culver City, California has up-to-date printed citywide sewer GIS map book and online sewer access system to share data with public.

Heat exchangers and condensers are subject to fouling, corrosion, biofouling and scaling due to the quality of cooling water and operating conditions prevailing at the power stations. Scaling or fouling in the condensers result in loss of vacuum, increase in heat rate and consequently loss in generation, whereas corrosion results in damage to condenser tubes and damage to condenser tubes and damage to boiler tubes. Recently NETRA investigated and implemented remedial measures in respect of severe scaling and fouling of a power plant having two units of 110 MW each.

Thermax executed the largest augmentation job in India, by doubling the capacity of existing 68.1 MLD plant to 136.2 MLD at no extra space.
