Vision Earthcare (VEC) is the Prime Technology Provider providing design, specialties, project management, commissioning and O&M/AMC services for natural ecofriendly technologies developed by various Research Groups (Public and Private) under Soil Bio Technology®/ CAMUS®/ SBT® brand. VEC provides Nature-Based Technologies for Sewerage and Sanitation which includes STP/ETP, Lake/Nallah Rejuvenation, Septage Management and Solid Waste Management. The initial technology Constructed Soil Filters type Soil Bio Technology (CSF-SBT) was patented by IIT Bombay in 2002 as an outcome of research efforts from 1990s to 2000 on Pheretima Elongata GeoPhagus Earthworms and Red Soil as Bio Media. Post this research Vision Earthcare collaborated with Prof HS Shankar (hss@iitb.ac.in) to improve the process to address market imperatives. The research collaboration from 2005 to 2013 resulted in the advanced version of SBT using vastly superior soil ecology deploying Acarine Orbatid Soil Mites and Granular Porous Natural and Artifical Bio Media being promoted as Continuous Advanced Multistage System using Soil Bio Technology (CAMUS-SBT). A note explaining the diference between CSF-SBT and CAMUS-SBT is outlined in this advisory by Prof H.S Shankar. Differences between CAMUS-SBT technology and CSF-SBT Technology The main improvement was a 4 fold reduction in space requirements from CSF-SBT (2sqm/KLD) to CAMUS-SBT (0.6 sqm/KLD) in 2022. Further reductions in space incidence from 0.6sqm/ KLD to 0.2sqm/KLD is underway by the VEC team. VEC functions as a green technology firm with the mandate to create/integrate sustainable waste recycling technology alternatives by understanding the genius encoded within the earth's ecosystems, together with engineering innovations that make Sewage Treatment very simple. VEC has used the unique power of soil ecology for waste recycling called Soil Bio Technology ® marketed under the brand CAMUS ®-SBT ® (Continuous Aerobic Multistage System using Soil Bio Technology). Soil Bio Technology ® has proven track record to treat sewage (domestic wastewater) and other industrial waste water effectively and economically with over 300 nos (with an installed capacity ~300MLD) CSBT type Sewage and Effluent Treatment Plants (ETP/STPs) have been installed across India over the last 20 years. CAMUS®-SBT® consumes less energy i.e. almost 1/3 of the conventional STPs and due to constant research the space requirements also approach conventional technologies such as MBBR/SBR/ASP. The technology was developed by Prof H.S Shankar's group at I.I.T Bombay and in over 30 years of sustained work multiple PhD, Masters, Bachelor students and Research scholars have developed methods to harness the power of soil. Technologies developed under this aegis have been patented in India and US. VEC has demonstrated these technologies in its service to various industries, institutions and communities across India and the World. More than 300 SBT plants have been successfully running across India with an installed capacity of ~300 MLD (~Water generated by 30 Lac people equivalents) until April 2022. 300 MLD of project using CAMUS-SBT constitutes largest portfolio of nature based waste water treatment globally. Our vision is to provide smart sanitation and wastewater treatment solutions to create a sustainable world. We are proud to share that our technology contributes directly to the Goal 6: Sustainable Water Management and Sanitation of the Sustainable Development Goals-2030.
