Soil Biotechnology alias SBT system of wastewater recycling has been developed by Indian Institute of Technology Bombay (IITB) indigenously after two decades of research. Dr. Avinash Kadam, MD of SUGAM has been associated in the development of this technologyat IITB. SUGAM has tied up with SINE IITB uncubated company for promotion of this technology and to unterface with the end users at national and international levels.
Its a green engineering approach and is considered as notable technology contributions from IITB to waste management. It has several national & international credentials. SBT is based on a bio-conversion process, practically maintenance free, does not produce biosludge & foul odour, consumes least energy, gives River water quality and has green aesthetic. Its operation is simple, economical & energy efficient.
It has served industries, housing societies, resorts, schools/universities/ashrams, hotels, municipal corporations & air ports. It can be applied to: (i) Sewage recycling for reuse in construction, cleaning & gardening, ground water recharge; (ii) Industrial air purification (volatile organic emissions); (iii) Primary purification of drinking water as well swimming pool water; (iv) Purification of Industrial effluent of organic nature (e.g. Pharma, Specialty chemicals, Dairy, Distillery, Wineries, Paper & Pulp mills, etc).
SBT systems are typically housed in RCC, stone-masonry or soil bunds and consists of an impervious containment. It starts with a underdrain layer, above which lies a layer of media housing culture and bioindicator plants. Water first passes through the additive layer and subsequently passes through the media. The process can be run as single stage or multistage depending on water quality desired. The recirculation is provided for further polishing if required. Following figure depicts the typical sectional view of SBT system.
It has served industries, housing societies, resorts, schools/universities/ashrams, hotels, municipal corporations & air ports. It can be applied to:
SBT Technology holds the promising solutions for water security of the country via:
Some of the national & international credentials of SBT are as:
In Industry, technology is being extended for zero liquid discharge for following applications:
