Summary of the talk on Algal Biomass Production – Challenges - V Sivasubramanian

Algal biomass has become an important feedstock for the production of a variety of valuable compounds for human welfare. Nutraceuticals, pharmaceuticals, pigments, food colours, cosmetics and bio-fuels are some of the important applications of algal biomass. Seaweed cultivation for phycocolloids like agar, alginate, agarose and carrageenan are well known. CSMCRI, Bhavnagar has been involved in developing indigenous technologies for cultivation, harvesting and production of these phycocolloids and fertilizers from seaweeds and transferring the technologies to industries. Cultivation systems for seaweeds are well established and out of thousand and odd seaweed species in India only a few species are cultivated and there is a need to develop cultivation technologies for rest of the seaweeds.
With regards to micro algae production there are challenges and issues which should be addressed at every phase of technology development. Right from species collection, identification, isolation, cultivation in lab scale and at industrial scale we have several issues and bottlenecks which Indian scientists are trying to address to make the process commercially viable. The cost of algal biomass production is the major factor which determines viability. Nutrients costs constitute 30% of production cost apart from harvesting and processing costs. One of the suggestions provided by PERC, Chennai, which has been working on micro algae technology to treat industrial wastes for the last 15 years, is to integrate algal biomass production with wastewater treatment to cut down 30% cost. Production systems include photobioreactors, raceway ponds and hybridized systems. PERC recommends a vertical system which it has implemented with great success in industries in India and abroad which addresses the problem of CAPEX and OPEX, space restriction and many other drawbacks we find in other systems. Productivity issue could be addressed by improvement of algal strains through selection, metabolic and genetic manipulations, optimized designs of tanks, PBRs etc, growth engineering which involves nutrient input management and harvesting schedule and pond management practices.

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

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

Millions of tons of inadequately treated sewage and industrial and agricultural wastes are dumped into the world’s waters. Water contamination of natural ecosystems affects humans directly by destroying fisheries or causing other impacts on biodiversity that affect food production. Most polluted freshwater ends up in the oceans, causing serious damage to many coastal areas and fisheries and affecting our ocean and coastal resource management challenges. A wide range of human and natural processes affect the biological, chemical, and physical characteristics of water, and thus impact water quality. Contamination by pathogenic organisms, trace metals, and human-produced and toxic chemicals; the introduction of non-native species; and changes in the acidity, temperature, and salinity of water can all harm aquatic ecosystems and make water unsuitable for human use.

Micro algal technology provides an effective solution
Phycoremediation employs photosynthetic micro algae which are capable of removing inorganic nutrients and in symbiotic association with bacteria can also effectively handle organic load of natural water bodies thereby increasing dissolved oxygen levels (reduction in BOD and COD).
With a decade long experience in handling highly hostile industrial waste waters, Dr V Sivasubramanian (PERC) has developed a treatment system (which can be also customized) to restore water bodies which are heavily contaminated. TYPE I:
A simple algal treatment tank system with the conventional pretreatment facilities which can be installed at specific locations identified based on a pre-installation survey of water body. TYPE II: Micro algal treatment system with a sequence of algal treatment tanks with reduced retention time for more efficient treatment of contaminated water. Algal treatment tanks will be designed to suit the treatment site ( horizontal system or vertical systems). When the space available is sufficient micro algal treatment tanks may be installed as shallow high rate oxidation ponds. If the space is limited a vertical system supported by an advanced illumination/aeration panel (designed and developed by PERC) may be installed.

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.

FLUE GAS/CO2 MITIGATION USING MICRO ALGAE TECHNOLOGY AT ONGC PLANT

V Sivasubramanian has successfully installed and demonstrsted micro algae technology to mitigate flue gas at Hazira Natural Gas processing Unit of ONGC. Small scale algae system is successfully capturing flue gas at this demo plant- On an average dry weight of 0.5 g/L/day was achieved which is very significant in terms of productivity, as productivity is a measure of carbon fixation (for 1 g dry weight of algal biomass 1.86 grams of CO2 is fixed). The CO2 fixation potential of raceway pond is approximately 1 gram/L/day.
