SERI – Introduction

•    SERI started in 1995 with an aim towards the clean environment with the help of natural technologies, Eco-technologies to treat wastes. It has been well experienced that conventional physicochemical and biological treatment systems require high material and energy inputs to obtain desired results consequently leading to high capital and operating costs.

•    The major objective of SERI is to develop cost- effective, indigenous technologies based on natural, ecological engineering principles for the river basin management.

•    SERI has effectively and successfully employed pollution control technologies using ecotechnological principles to treat the pollution from point sources i. e. industries and residential areas and non-point sources like city drains.

•    SERI has conducted a number of Environmental Impact Assessment studies for industrial and infrastructural projects with public hearing, socio-economical aspects and impacts from 1998 onwards including for Pune Municipal Corporation’s Redevelopment Infrastructure Project of 1000 crores. It included environmental and social assessments for Road and transportation hub projects, cycle track projects to obtain funding from international financial institutions.

•    The range of treatment systems included from 1 cu m / day to 128000 cu / day in last 13 years. The SERI’s work started with one pilot plant study at industrial unit having mix of industrial and domestic wastewaters. Since, then using ecotechnological treatment systems SERI has treated wastewaters containing textile dyes, cyanide and toxic metals also to a satisfactory level.

•    Use of innovative horizontal filtration is unique kind of system SERI installed for the help of College of Military Engineering, Pune, in association with Clean River Committee, and Cummins Foundation in 2003. It has revolutionized the approach to treat the waste flowing through streams and rivers and control of lake pollution.

•    SERI has worked on control of pollution and ecological designing of about 25 lakes all over India including Konkan, Western Maharashtra, Marathwada and Vidarbha, Andhra Pradesh, and Rajasthan. A successful designing of management plan for Pandharpur  and Katol Lakes has received state grant for restoration programme.

•    SERI is well – known in water audit and assessments. SERI has designed a number of rainwater harvesting schemes for industrial, domestic units and colleges.

•    SERI has organized a number of educative and environmental awareness programmes for students and masses all over Maharashtra since its inception in 1995 under the leadership of Sandeep Joshi, Environment Technologist, including innovative programme of Ecology Day which was attended by world renowned scientists of ILEC, Japan.

Outstanding work
•    College of Military Engineering, Pune to treat 72 MLD (7.2 crores litres) wastewater by Natural waste treatment system (Sparkling Stream) and many more projects are in process for world-renowned institutions. Designed and guided respective agencies for the treatment of Ambil and Sandvik in Pune, Waldhuni in Kalyan, Jayanti nalla, Kolhapur and Paneri nalla, Palghar.

•    Entrusted by Mula - Mutha River Restoration Committee, River Action Group headed by INTACH, Pune Chapter, to design the systems for nalla and river water purification (schemes for three nallas were designed).

•    Worked on feasibility report for restoration of water quality of Pushkar Lake, Pushkar, Ajmer, Rajasthan. Evaluated the application of ecotechnological treatment for the control of lake pollution for 4 different water bodies in Hyderabad for HUDA.

•    Developed DPR for CETPs in Chikalthana, Waluj and Shendre MIDCs of Aurangabad.

•    EIA of Pune Redevelopment Project for Pune Municipal Corporation (2007). EIS for a road in Pune as required by the Experts’ Committee appointed by Hon. High Court, Mumbai (2010)

•    As a trusted “Ecological Designer for eco-restoration of water bodies like lakes and rivers” SERI is working on various projects including one prestigious project Manikonda Lake supported by WIPRO, Ahar River Ecological Restoration Project, Udaipur, Noyyal River Ecological Restoration Project, Tiruppur etc.

•    Working with Zoning Atlas Project Division of Maharshtra Pollution Control Board on one of the pioneering project of Eco-village Katewadi near Baramati.

•    Excelled in treatment of textile wastewater having dyes and pigments using ecotechnological systems

Some Examples

1. It has been experienced in school in Baroda that 50 cu m sewage without segregation of solids is being treated using Soil Scape filtration with use of 8 units electricity, since there is no gravity benefit. So, only pumping is needed. The treated BOD is less than 16 mg / L since from 2 years the plant became operational. By conventional method, they would have required at least 50 units of electricity every day with some additional cost for consumables.

2. In one food processing unit about 50 km from Pune, 30 cu m industrial wastewater having COD more than 1000 mg / L and BOD more than 440 mg /L is being treated from last 4 years with consistent outlet COD and BOD less than 80 mg / L and 32 mg / L respectively. They have found it very cost effective as far as electrical consumption is required for conventional mechanistic systems.

3. The coloured effluents from the textile units are also treated using Soil Scape filtration system. The colour reduction in two stage filtration system is consistently is more than 90%. These plants are successfully running in Baroda and Jaipur from last 3 years. The precursors of dyes and pigments are also treated considerably - upto 95% COD reduction – the biological system found to be adapted to such difficult pollutants.

4. Technique uses natural slopes of polluted drains, beds, banks of streams or pond to augment the aerobic activity in water by creating turbulence and providing shallow depths to allow sun – light to penetrate the water column. This is a simulation of stream flow in the wilderness. It facilitates the free flow of water splashing due to stones and cascades. It is observed in nalla treatment project in Pune installed in 2004 that the dissolved oxygen in the water increases multifold – in some already installed systems. This increase is upto 90 – 120 times i. e. (from 0.1 to 8 – 12 ppm).
