N0 electricity, manpower or chemicals used in reed bed plantation STP
The sixth industrial expo organized by SIIDCUL Manufacturers Association at Premnagar Ashram which concluded on Sunday proved that people’s interest is turning towards eco-friendly technologies be it biodigester toilets or sewage treatment plants and biodegradable plastics. In all 150 exhibits were put up by different industries out of which maximum were from Uttarakhand.
The president of SIIDCUL Manufacturers Association, Harendra Garg said, “Eighty percent of the exhibitors were out of the state of Uttarakhand this time. The whole purpose and aim of holding this expo could be met out to strengthen the base of local industries by bringing more response from other states. Industries from the northern and western part of India had come. It was packed with seminars and workshops with eco-friendly technologies on display. Unlike a fair which is crowded for small affairs, this expo invited serious buyers who were interested in specific products and machinery only.”
One of the exhibitors from Roorkee, Enviro Connect had industry services like rainwater harvesting, bio-digestor toilets, eco-tech based sewage treatment plants on display. Speaking to this correspondent, founder, and owner of Enviro Connect, Akshat Bhateja said, “Eco technology based STPs are gradually capturing minds of state machinery as well as medium sized enterprises. This sewage treatment plant is not run with any machinery but reed bed plantation. The sewage waste is passed through specially fabricated septic tank with reed bed plantation. No power, chemical or machinery is required. The sewage is treated by plants and this technology has been patented by Indian Institute of Technology (IIT) Mumbai. We are the sole promoter of this technology in Uttarakhand in private sector.”
Notably the technology was patented in 2015-16 and CSIR- NIRI is also promoting this technology. This technology is approximately 20 per cent cheaper than conventional STPs and recurring costs are even more less.
Bhateja further said that the state government was running a pilot project in Ibrahimpur near Roorkee. Earlier the sewage was going into a pond which had become a local threat as breeding ground of water borne ailments. But now the sewage outlet is connected to the STP with reed bed thus making the pond free of bacteria or any kind of contamination. The released water can be easily used for irrigation and washing purposes.
When asked about the life of the reed bed system, Bhateja said, the plant canna indica grows to flowering stage in three months. One needs to cut down the flowers of the plant and it has a cycle of three months to bloom again. “Theoretically the life of the plant bed is 30 years and practically we have seen this run for 10 years. After that plant bed may need replacement and some enzyme coating in the tank,” he informed. Read more posts…
