   Worm o’ Filter  Wastewater Treatment Technology  Introduction ã Vermifiltration is an natural biological waste water treatment system which works with live earthworms and microbes. ã The earthworms’ gut act as a bioreactor  whereby there is reduction in the sewage wastewater’s solid and liquid organic wastes through ingestion and expelling these as vermi-compost. ã Vermifiltration significantly decreased the sewage water’s physicochemical parameters.   ã The vermi-treated sewage achieves the pollution control board set standards for irrigation water. ã Vermifiltration technology can therefore be applied as an environmentally friendly and an economically viable  technique for treatment of sewage water & use it in Irrigation  purposes.  ã It has been found that Municipal wastewater when treated with vermifiltration technology, there was a considerable reduction in the ã Biological oxygen demand (BOD5) by 95%, ã Chemical oxygen demand (COD) by 85%, ã Total soluble solids (TSS) by 95%, ã Turbidity by 95% ã Increase in Dissolved oxygen levels up to 4 and ã No odour. ã Vermifiltration significantly decreased the sewage water’s   physicochemical parameters. ã The vermi-treated sewage water compared well with the set standards for irrigation water. ã Vermifiltration technology can therefore be applied as an environmentally friendly and an economically viable  technique for treatment of sewage water treatment for & use it in irrigation purposes .   Cont …    Photographs
