Recycling waste water from kitchen, dining halls, and bathing halls to water the plants
A Waste Water Recycling Plant was installed in 2006 designed to process 20000 liters per day (LPD) waste water with the support, design and installation help from Central Leather and Research Institute, Chennai (CLRI). Waste water is collected from kitchen, dining halls and bathing halls. Treated water is used for watering the plants inside our campus.
The present strength of our inmates is almost doubled and the usage of water is around 60000 LPD. To treat the excess water the Waste Water Recycling Plant is upgraded to process 60000 liters per day (LPD) with the addition of FICCO reactor and other upgradations.
We expect full utilization of waste water after treatment will add to water conservation. The upgraded plant will help in - very low COD (Chemical Oxygen Demand), efficient treatment of water, reduction in sludge generation, foaming and odor and others.
A biogas plant for recycling kitchen and vegetable waste
The Biogas plant is considered to be a cheap source of energy. Biogas formed after decomposition of organic wastes in biogas plants is piped to kitchen for cooking. Biogas is produced in a no "oxygen is present" environment or in an anaerobic environment, when certain bacteria decompose organic material like kitchen waste and vegetable waste. The whole process is referred to as anaerobic digestion (AD). The Biogas plant is considered to be a cheap source of energy.

Biogas is produced in a no "oxygen is present" environment or in an anaerobic environment, when certain bacteria decompose organic material like kitchen waste and vegetable waste. The whole process is referred to as anaerobic digestion (AD).
The process produces a renewable energy source like methane. The byproduct produced during the process is a solid residue which is high-grade manure. Biogas is used for cooking in a specially designed burner. In the Students Home the Bio Gas plant was installed on a trial basis and upgrading the plant is under consideration.
