<\/a>What are the Green Technologies being used in Sustainable Water Management?<\/strong><\/span><\/h2>\n\n\n\n\n\n\n\n\n\n
Biofilters for storm water<\/strong><\/td>\nThe storm water is filtered by retrofitting conventional biofilters<\/span>. There is a submerged<\/span> (partly anoxic<\/span>) zone<\/span> with an embedded carbon source<\/span>. This helps in cleaning storm water.<\/td>\n<\/tr>\n
Denitrification<\/strong><\/td>\nDenitrification and removal of copper from storm water have significantly improved the storm water quality. The use of E.Coli<\/span> improves the water quality for secondary use.<\/td>\n<\/tr>\n
Bioreactors<\/strong><\/td>\nA bioreactor is a device containing bacteria and microorganisms<\/span> placed on a moving bed biofilm reactor. The waste is deposited on a packed or fibrous bed<\/span> and attached to a membrane to form a biofilm.<\/td>\n<\/tr>\n
Biofilters<\/strong><\/td>\nMicroorganisms or bacteria are allowed to grow on biofilters to make a biofilm. Wastewater is passed through biofilm<\/span> which will speed up the degradation of pollutants<\/span> and organic matter<\/span> present in the waste water.<\/td>\n<\/tr>\n
Bioremediation<\/strong><\/td>\nMicroorganisms are applied to the wastewater sites to remove dangerous species<\/span> or to convert toxins into less or non-toxic materials<\/span>.<\/td>\n<\/tr>\n
Electrowinning <\/strong><\/td>\nCurrent is passed through wastewater<\/span> with the help of electrodes. Metals are then electro-extracted from their oxidized forms<\/span> to deposit on the cathode. Heavy metals including copper<\/span>, nickel<\/span>, silver<\/span>, gold<\/span>, cadmium<\/span>, bismuth<\/span>, cobalt<\/span>, and others can be recovered
\nfrom wastewater through electrowinning.<\/td>\n<\/tr>\n
Desalination <\/strong><\/td>\nDesalination technologies are being used to produce freshwater from seawater.\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Other Green Technologies employed in the field of Water Management<\/p>\n\n\n\n\n\n\n
Forward Osmosis <\/strong><\/td>\nIt uses a new eco-friendly chemical compound<\/span> to draw the water molecules through a membrane leaving the salt behind. Then we separate the chemical from water<\/span> through a heating process. This
\nchemical can be reused in the process.<\/td>\n<\/tr>\n
Clathrate Desalination<\/strong><\/td>\nThis technique traps water molecules in carbon dioxide<\/span> and pressurises water molecules into clathrate crystals<\/span>. Later, these crystals are broken down to release freshwater.<\/td>\n<\/tr>\n
Dewvapouration <\/strong><\/td>\nThis technique humidifies a stream of heated air<\/span> by running a stream of saline water on a heated surface.<\/td>\n<\/tr>\n
Freeze<\/strong>
\nDesalination <\/strong><\/td>\n		It uses the phase shift of water from liquid to solid state<\/span> to remove salt from the ice crystals.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

<\/a>What are the advantages of using green technology for sustainable water management?<\/strong><\/span><\/h2>\n

1. Averting the water scarcity-<\/strong> The indiscriminate exploitation and poor management of water has reduced the per capita annual availability of water, from 1816 cubic metre (cu m) in 2001, to 1544 cu m in 2011 to 1140 cu m in the year 2050<\/span>. The use of green technology will help in averting the water scarcity.<\/p>\n

2. Countering negative effect of climate change-<\/strong>\u00a0 The use of green technology helps in augmenting the supply of water<\/span>, falling water table<\/span>, water quality<\/span>, and climate change.\u00a0<\/span><\/span><\/p>\n

3. Treatment of Waste water-<\/strong> Waste water treatment using green technology helps in increasing the water resource availability in the country. For ex-<\/strong> Use of Bioremediation<\/span>, electrowinning technology<\/span> helps in effective treatment of waste water.<\/p>\n

4. Economic Growth and Job Creation-<\/strong> The employment of green technology offers potential for job creation in manufacturing<\/span>, installation<\/span>, maintenance<\/span>, and research and development<\/span>.<\/p>\n

5. Improved Public Health-<\/strong> Green technologies in sustainable water management increases the pollutants removal-efficiency<\/span> and nutrient recovery. The <\/span><\/span>protection of human health and the environment improves with the employment of green technology in water management.<\/p>\n

<\/a>What are the Success stories of successful implementation of Green technologies?<\/span><\/strong><\/h2>\n

1. Deep Tunnel Sewerage System-<\/strong> The Deep Tunnel Sewerage System is a massive underground superhighway for Singapore’s used water management<\/span>. The DTSS has adopted green technologies like energy efficient pumps, advanced membrane bioreactors, and a cogeneration plant that converts biogas into electricity. This process has resulted in reduced <\/span>energy consumption<\/span>, lowered carbon emissions<\/span>, and increased resource recovery<\/span> from wastewater.<\/p>\n

2. Employment of Bio-remediating technique by Oil India-<\/strong> Bio-remediating technique by Oil India reduces oil contamination in water bodies<\/span> so that these areas can be made conducive to the growth of aquatic life.<\/p>\n

3. Werribee Treatment Plant in Melbourne-<\/strong> It has successfully implemented green technologies to achieve sustainable management of wastewater. Each year the plant produces 40 billion litres of recycled water<\/span> which is then used for irrigation of parks, golf
\ncourses, and agricultural lands.<\/p>\n

<\/a>What are the challenges in the use of green technology in sustainable water management?<\/strong><\/span><\/h2>\n

1. Scalability and Cost-Effectiveness-<\/strong> The scalability and cost-effectiveness of green technologies for small-scale or remote applications<\/span> is a major challenge for a developing country like India.<\/p>\n

2. Low Public Acceptance- <\/strong>There is low public acceptance of non-chemical water treatment method. It is also influenced by various factors, like economic conditions<\/span> and changes in government policy<\/span>.<\/p>\n

3. Huge requirement of Investment and Financing-<\/strong> The implementation of green technologies requires significant investment and financing<\/span>. The requirement of huge investment and finance is a challenge for governments, industries, and individuals.<\/p>\n

4. Environmental Impact-<\/strong> Green technologies can have unintended environmental impacts, such as changes in local ecosystems<\/span> or water quality<\/span>.<\/p>\n

5. Integration with Existing Infrastructure-<\/strong> Green technologies require integration with existing infrastructure. This is can be a challenge due to compatibility issues<\/span>.<\/p>\n\n\n\n

<\/a>What Should be the Way Forward?<\/strong><\/span><\/h2>\n

1. Research and Development-<\/strong> Continuous research and development are essential for identifying and implementing green technologies<\/span> that are suitable to the needs of the sector.<\/p>\n

2. Collaboration with the stakeholders-<\/strong> The researchers<\/span>, engineers<\/span>, and industry professionals must innovate and collaborate<\/span> to increase the adoption of green technology in water management.<\/p>\n

3. Public Policy for Green technology adoption-<\/strong> There must be emphasis on the development of Policy frameworks that include financial incentives<\/span>, tax breaks,<\/span> and regulatory requirements that drive the adoption of green technologies<\/span>.<\/p>\n

4. Public Awareness Programs-<\/strong> Massive public awareness programs along with behavioural change are the key to encourage the public and state<\/span> towards the embracement of green technology.<\/p>\n\n\n\n
