GREY WATER MANAGEMENT USING PHYTOREMEDIATION: GREY WATER MANAGEMENT USING PHYTOREMEDIATION PRESENTED BY ASWIN KUMAR K S III YEAR CIVIL DEPT CURRENT STATUS OF TAMILNADU:: CURRENT STATUS OF TAMILNADU: OBJECTIVE:: OBJECTIVE: To reuse the water To reduce the cost of treating waste water Natural way and simpler way Improve the quality of waste water Recycling aid which suits for all houses GREY WATER:: GREY WATER: GREY WATER:: GREY WATER: Waste water from Domestic Houses and Buildings Contains Salts Organic and Inorganic wastes Bathroom wastes and kitchen waste water cloths washing wastes Micro Solid wastes Light yellow to Grey colour PHYTOREMEDIATION:: PHYTOREMEDIATION: Phytoremediation is an emerging technology that uses various plants to degrade, extract, contain, or immobilize contaminants from soil and water. Types: Phytoextraction Phytostabilization Phytotransformation Phytostimulation Phytovolatilization Rhizofiltration PHYTOFILTERATION OR RHIZOFILTERATION:: PHYTOFILTERATION OR RHIZOFILTERATION: Rhizofilteration involves filtering water through a mass of roots to remove toxic substances or excess nutrients. Adsorption or precipitation onto plant roots or absorption of contaminants in the solution surrounding the root zone. Used to remediate extracted groundwater, surface water, and waste water with low contaminants. STAGES INVOLVED IN MANUFACTURING:: STAGES INVOLVED IN MANUFACTURING: MATERIALS USED: SAND GRAVEL: MATERIALS USED: SAND GRAVEL HOW DOES IT WORKS ?: HOW DOES IT WORKS ? Contaminated water is passed through the main pipe It is stored between the roots of rhizofiltrate plants The roots absorb the contaminated compounds in the water and purifies it Then the purified water is passed through a filtrate Which contains layers of coarse aggregate and fine aggregate The filtrate blocks the solid wastes The outlet water is clear and it is poured into the storage sump MODEL DIAGRAM: MODEL DIAGRAM TYPES OF PLANTS USED: : TYPES OF PLANTS USED: Plant species are selected for use based on factors such as: ability to extract or degrade the contaminants of concern adaptation to local climates depth root structure compatibility with soils growth rate ease of planting and maintenance ability to take up large quantities of water through the roots . PLANTS USED: TULSI(Basil): PLANTS USED: TULSI(Basil) Properties: Anti-pollutant Anti-bacterial Anti-fungal Anti-viral Slide15: CANNAS: Breaks down organic compounds in grey water Consumes inorganic compounds WATER HYACINTH PLANT:: WATER HYACINTH PLANT: REMOVES: Heavy metals Organic and Inorganic wastes One of aquatic plants Root is dense and bunchy HEDYCHIUM:: HEDYCHIUM: Antimicrobial Breaks down inorganic wastes of washing UMBRELLA PALM:: UMBRELLA PALM: Removes: Chemical compounds Pollutant in water as well as sludge's LEMON GRASS:: LEMON GRASS: Removes microbes Antifungal MAINTENANCE:: MAINTENANCE: Once the plants get decayed or cant able to do its work Removal of those plants have to be take place Replantation of required plants must be done Burying of the decayed plants is the best way to dispose the decayed or dead plants burning of plants may leads to production of new chemical compounds How long does Phytofilteration takes? : How long does Phytofilteration takes ? The time depends on: Type and number of plants used Type and amount of harmful substances present Time duration varies from 1 to 7 days PROS:: PROS: I n situ and E x situ applications. S olar energy only Avoiding microorganisms Cost effective A esthetically pleasing Household needs CONCLUSION:: CONCLUSION: Phytofilteration is an emerging technology that employs the use of higher plants for the cleanup of contaminated water. The possibility of using biotechnology to improve the efficiency of phytofilteration processes makes even better than any other existing methods. THANK YOU: THANK YOU
