Electro-chlorination Systems in India gets a boost with Increasing Investments in Power and Municipal Sectors, notes Frost & Sullivan

Mumbai, India – 30th November, 2011 - Electro-chlorination has been accepted globally as the most cost-effective and suitable disinfectant for water. With 72 percent of the Indian population living in rural areas, electro-chlorination will emerge as a big market to tap into, due to the pressing requirement of clean water here. The Indian Government has earmarked 20 percent of Accelerated Rural Water Supply Program funds for water quality and electro-chlorination is expected to play a crucial role in addressing the same.
Industrial investments, coupled with urban and rural water quality requirement, will make electro-chlorination an evergreen and preferred choice for water disinfection for government bodies and industries alike.
Electro-chlorination is used for polishing or disinfection of water after it has undergone tertiary treatment. The major application areas for electro-chlorination equipment in India include the power sector, cooling towers, rural water supply, municipalities, and swimming pools. The power sector, cooling towers, and municipalities generally use continuous chlorinators. They have the necessary expertise to control and efficiently manage the equipment. Swimming pools use both continuous and batch chlorinators, while in rural areas batch chlorinators are preferred. Batch chlorinators are bulky, but are easy to operate and maintain. As people in rural areas lack the necessary skills and expertise to handle complex equipment, batch chlorinators are used in these areas. Continuous chlorinators are compact, but users need the right education to understand the technology and expertise to operate and maintain them. Hence, these are used in organised sectors such as in heavy industrial segments like Power, and Oil and Refineries etc.
Electro-chlorination is an efficient and proven technology for disinfecting water from disease-causing pathogens and bacteria. Sodium Hypo Chlorite (SHC) is produced by the electrolysis of seawater. SHC is used as a chlorinating agent for disinfection. Alternatively, brine prepared by mixing salt and water could be used as raw material, and electricity as an external agent to carry out electrolysis, wherein Hydrogen and SHC is generated. The liquid SHC obtained is very corrosive to metallic materials, so plastic containers are used for storage. Onsite production or generation of SHC is a preferred option in many countries and across end-user industries.
Disease causing pathogens such as E-coli, Giardia cysts, and Cryptosprodium spores can be found in cattle faeces and come in contact with water while it seeps in ground or mixes with rainwater. Another pathogen, Legionella, is generally found in water from cooling towers, swimming pools, and domestic hot water systems. These can be effectively controlled through electro-chlorination.
Worldwide, 50 million tonnes of chlorine is produced annually, of which 2.5 million tonnes or US $1.4 billion is used for disinfection of water. Universally, it has been accepted as the best disinfectant. European countries are contemplating the use of ozone as a disinfectant for municipal water, but electro-chlorination remains the preferred technology for industrial water disinfection. Even though alternative disinfectants have several benefits, electro-chlorination has been accepted as the most preferred disinfectant for water. The reasons are:
· Easy and cheap availability of raw materials such as salt or seawater, water, and electricity
· Onsite easy generation of SHC
· Can be easily controlled
· Storage is not a problem if concentration is below 1 percent by volume
Most companies providing electro-chlorinators in India have an ISO 9001:2000 certification and abide by the Bureau of Indian Standards. The CPCB (Central Pollution Control Board) under the Water (Prevention & Control of Pollution) Amendment Act 1988 is responsible for monitoring the water quality and maintaining standards. It advices the Central Government concerning any matter related to water and air pollution and provides technical assistance to State Boards on these matters. According to a CPCB directive, chlorine concentration of less than 0.2 mg/l should be maintained at the customer's tap. Anything in excess of this limit is carcinogenic in case of prolonged use.
The major factor which restrains this market in India is the low awareness among end-user segments. As a result, the electro-chlorination market size has not grown much in the past 2-3 years as commented by industry experts.
The Brihanmumbai Municipal Corporation (BMC) utilizes 4,300 tonnes of chlorine, expending about INR 130 crore per year for disinfection of water. This reflects on the huge electro-chlorination market potential in India. Although the market is large, it has not grown much in the past few years. According to industry experts, it will take 5-10 years more for electro-chlorination to be accepted as a potential disinfection technology.
