Presentations

Specific methods used were automation of localized water storage system, elimination of water wastage by providing timer for water supply, constructing pond for harvesting rain water, optimisation of paint sludge pit cleaning, installation of screw compressors without cooling tower compressors, installation of spot cooling system, inst

The company has achieved this through recycle and reuse of wastewater, reducing water consumption by process changes, improving water efficiency in existing processes, implementing zero discharge effluent and reverse osmosis projects, reducing soft water consumption, eliminating water softener usage and using a new liquid surface conditioner.

 This has been carried out through strengthening its water monitoring system by installation of water meters at source points, recycling of effluent of reject pit discharge to abandoned mine pit, zero effluent discharge by providing sedimentation tanks and re-utilisation of effluent. Apart from water, work was also done on reducing Greenhouse gas emissions.

This work that included domestic waste-water recycling, reduction in river water usage, and by close circuiting of process water.won the 

It has achieved this through the use of dry low NOx burners, air cooled condensers, rainwater harvesting through building a pond, improving recovery in its reverse osmosis water treatment process and by increasing the cycle of concentration in its auxiliary cooling tower.

This is a detailed introductory presentation about ground water and hydrogeology, and helps to understand the basics of ground water & aquifers. The branch of geology dealing with surface & subsurface water is known as groundwater. The science of hydrogeology is defined as hydrology with emphasis on geology.

A concise explaination of the techniques used for groundwater exploration.Electrical well logging is a kind of geophysical logging tool for ground water exploration. It involves the continuous recording of electrical resistance, resistivity and spontaneous potential (SP) of formations of a drilled bore hole. This helps to identify the formations and also delineate freshwater aquifers from saline aquifers.It is also used to delineate the fracture system in hard-rock terrain, for rejuvenation of poor/low-yielding bore wells.

A consultation was organised by Arghyam Trust in September 2009, to share experiences on Sustainable and Ecological Sanitation with the Planning Commission.

The following case studies on drinking water management, describe the efforts of Pravah and its partner organisations, in organising drinking water at the village level, along with rural communities of Gujarat.
