Research Focus and consultancy offered

Dr V Sivasubramanian is involved in reasearch and development of algae based bio-remediation technology (PHYCOREMEDIATION) to manage a variety of industrial effluents inluding chemical, textile and leather industries. He is a pioneer in taking algae based technology to industrial scale to manage effluents from chemical industries, petrochemical industries, pharmaceutical industries, steel industries etc. Major parameters like BOD, COD, and sludge are reduced. R/O rejects from dyeing and leather industries can be better managed and a pretreatment with algal technology reduces hardness of most of the industrial wastewaters thus increasing the life of R/O membranes.(V Sivasubramanian, V V Subramanian, M Muthukumaran and R Murali. 2012. Algal technology for effective reduction of total hardness in wastewater and industrial effluents…Phykos. 42(1): …51 ..PDF). Consultancy is also offered to install micro algae based systems to sequester flue gas/CO2 in power, steel and other industries. Algal biomass production to develop bioenergy is another area Dr V Sivasubramanian is providing research support and consultancy to install pilot and largesacle production facilities.

1. Phycoremediation (HINDU article) (BIO-REMEDIATION using Algae)

Effluent treatment employing micro algae, popularly known as PHYCOREMEDIATION,(Click here for FAQ on Phycoremediation) is a natural and eco-friendly way of treating effluents for safe disposal. Dr V Sivasubramanian undertakes feasibility studies under laboratory conditions and also at field level and suggests algal technology to treat the effluent. Over the years he has developed a culture collection of potentially valuable micro algae and technology to successfully employ them at the field level with a very high percentage of success. He also suggests technology to utilize the biomass generated through phycoremediation. Based on his research support World's First Phycoremediation plant was developed at Ranipet, India in 2006. The highlights of the technology includes 1. pH correction without using any chemicals 2. Reduction of TDS, BOD and COD 3. Prevention of sludge formation 4. Degradation and decolourization of dyes and very effective way of treating dyeing industry effluents. CLICK HERE FOR NEWS ITEM IN DECCAN CHRONICLE ON EFFLUENT TREATMENT .

Bio- Remediation technology in Management of R/O rejects : Dr V Sivasubramanian presented algae based BIOREMEDIATION technology to treat R/O rejects at a Brain Storming Session (BSS) and working group meeting on management of R/O rejects of Leather and textile industries organized by DST at Anna University, Chennai on 9th and 10th March 2013. It was appreciated by the participanting industries.

2. Algal farming for biofuels and other valuable products

Dr V Sivasubramanian has developed technology to cultivate micro algae including marine diatoms by employing a combination of open ponds (phototrophic) and bioreators (heterotrophic). He has also developed through collaborative research an economically viable photobioreactor technology to grow algal biomass. Simple, efficient and cost effective harvesting technology (PHYCOFLOC) has been develpoed and put into operation in a number of algal farms all over India. Oil cake is used to make aquaculture feed and cattle feed. For more details on algal farming click here

3. Algal inoculum for aquacultre ponds

Dr V Sivasubramanian and his team has developed a gel type micro algal product for aquaculture ponds. This product reduces the cost of fish feed to a great extent. Fish become more active associated with better growth and weight gain. more


4. CO2 sequestration and flue gas mitigation ( Click here for News item in Deccan Chronicle)

The advantages of algae based technology: The microalgae for CO2-mitigation strategy offers numerous advantages. The microalgal CO2bio-mitigation could be made more economically cost-effective and environmentally sustainable, especially when it is combined with other processes such as wastewater treatment.

TECHNOLOGY: Dr V Sivasubramanian has developed algae based technology to mitigate flue gas and produce valuable algal biomass. Culture collection at PERC has some of the robust freshwater and marine micro algal species which can be very effectively employed in largescale mitigation at various industries. The technology developed by Dr V Sivasubramanian is being implemented at pilot scale and largescale flue gas mitigation in some of the industries. Dr V Sivasubramanian is collaborating with JSW Steel, Bellary and ONGC, New Delhi and a few other plants to implement this technology.

Successful development of algal consortium for flue gas mitigation:

Dr V Sivasubramanian has recently identified and developed a consortium of micro algae which can be successfully employed at large scale sequestration plants for flue gas mitigation. In the recently concluded dmomstration project he has employed this algal consortium at ONGC's Hazira plant at Surat and demonstrated its efficiency to capture flue gas CO2.

Objectives achieved:
The objectives of selection of micro algae, growing in a pilot plant at Hazira using scrubbed water have been achieved. Very high growth rate and dry weight were achieved with raceway pond and this productivity will improve considerably if a hybridized vertical system with advanced illumination system (PERC’s) is installed while scaling up.
Scaling up:
A hybridized vertical system fitted with advanced illumination/aeration panel (PERC’s design – Patent pending) with a tank depth of not less than 2 meters is suitable and only viable process for large scale flue gas mitigation systems based on micro algae. This will address the problem of space availability (100 times lesser space required than the conventional system) and efficiency required to handle the flue gas generated by the industry.

4. Restoration of natural water bodies - Lakes, rivers etc


Phycospectrum Environmental Research Centre (PERC), Chennai, has been involved in developing and implementation of microalgae-based treatment technologies for handling industrial effluents in India and abroad. pH correction, color removal, odor removal, COD and BOD reduction, and sludge reduction have been successfully implemented by PERC algal technology. Recently microalgae technology has been found to be suitable for handling reverse osmosis (R/O) rejects from desalination plants, leather industries, textile industries, etc. replacing the more expensive and energy intensive multiple effect evaporators (MEEs). Integration of pulsed magnetic field (PMF) technology, jointly developed by PERC in collaboration with Madras Institute of Magnetobiology, Chennai, has been very effective in enhancing the efficiency of algae-based remediation systems. PERC has selected a few robust and natural microalgae and customized micronutrients to support them and converted them into a product, Phycoplus, a nanotechnology based product. If administered, the treatment results in breaking of the dominance of the polluting algae and stripping off essential nutrients for the duckweeds to make them disappear. MORE


Phycoplus technology which is the most advanced nano tech, has been developed after 15 years of intense research for restoration of polluted lakes, ponds, rivers and fish ponds.It contains millions of selected robust natural micro algae as seed material along with symbiotic beneficial bacteria and an unique formulation of essential micro nutrients and trace elements which make the product unique and special.

The advantage we have over other similar products in the market is we not only include vital micronutrients but also include robust well tested micro algae along with beneficial symbiotic bacteria which makes the product superior and more effective in recovering polluted water bodies at a rapid rate. These microbes have been selected based on more than a decade of research and application in waste water treatment process at pilot and large scale by PHYCOSPECTRUM.

Phycovolatilization of heavy metals:

Using algae to treat industrial effluents containing heavy metals presents an alternative to the current practice of using other biosorbents and physical and chemical methods. In this study, effluent from a leather-processing chemical industry in Ranipet, Tamil Nadu, India, was treated for the removal of heavy metals using the microalga, Chlorella
vulgaris, which was isolated from the effluent itself. The results of the study show that after 8 hours, Chlorella vulgaris exhibited a better adsorption capacity under sunlight compared to laboratory conditions (i.e., 30.6 mg/g dry weight vs 10.5 mg/g dry weight, respectively). Similarly, reduction of heavy metals and mass balance in pilot-scale field studies conducted in a high-rate algal pond showed that the microalga, apart from adsorption, complexation, and entrapment mechanisms, is likely to possess phycovolatilization capability probably via biotransformation processes.

Collaborative project with Plymouth Marine Laboratory, (PML), UK

Project entitled “Using flow cytometry and genomics to characterize, understand andoptimize micro algal:bacterial consortia cultivated on waste water for the production of biofuel” supported by DBT, India and BBSRC, UK. (Reference: BT/IN/Indo-UK/SuBB/23/NT/2013 dated 30th August, 2013)

Micro algae are considered as favourite organisms for biofuels due to their higher photosynthetic efficiency and productivity than higher plants. Algal production still seems to be very expensive due to  higher capex and opex costs. Integrating algal production systems with waste water treatment can reduce dependence on valuable freshwater and expensive  nutrients. PERC, India has been involved in installing micro algae based effluent treatment systems in India and has a collection of robust algal species isolated from industrial effluent treatment sites. Interaction between symbiotic bacteria and micro algae plays a significant role in remediation and algal biomass production. Presence of bacterial population also would help in harvesting micro algae due to bioflocculating potentials. In depth study of this micro algal – bacterial interaction would help us understand the system better. This knowledge may help us in improving algal productivity and oil content and reducing cost of production considerably. Plymouth Marine Laboratory, UK has the expertise and latest techniques to investigate this interaction and PERC and BDU, India have the expertise in handling micro algal – bacterial systems in pilot scale and beyond.
The present collaboration will benefit both the countries in gaining more knowledge on this very crucial aspect of bacterial and micro algal symbiotic association.
