Phytorid Technology for Sewage and Industrial Wastewater Treatment Introduction:- PHYTORID is a scientifically developed systematic treatment methodology for waste water. PHYTORID combines Physical, Biological and Chemical processes. Works on gravity No electric power requirement Scalable technology Easy to maintain Adds to aesthetics Cost effective TYPICAL DESIGN FEATURES The general concept design for the Phytorid system is presented in Figure 1. However, the design may be further modified as per specifications and land availability. Figure 1: Cross Sectional View of Phytorid System Bed Sectional Plan View Next Inlet Parallel System Combined Series System Outlet The sub-surface flow type, Phytorid system is proposed for the treatment of sewage or domestic or industrial wastewater which will consists of a basin or a channel with a barrier to prevent seepage, but the systems/ cells/ beds contain a suitable depth of porous media. A primary treatment facility would also be constructed along with basic for effective removal of solids and thus reduces the marginal BOD. The porous media also supports the root structure of emergent vegetation. The design of the Phytorid system assumes that the water level in the cells will remain below the top of the filter media. The vegetation to be utilized for the said Phytorid system is very important. Various species of aquatic plants have been utilized to attain maximum efficiency in the treatment of domestic wastes. These include species like Phramites australis, Phalaris arundinacea, Glyceria maxima, Typha spp., Scirpus spp., other common grasses etc. ADVANTAGES OF PHYTORID TECHNOLOGY Treatment efficiencies for the removal of faecal coliforms, BOD, COD, nutrients are up to 95%, which is greater than the traditional chemical methods. It is a very cost effective technology when compared with the traditional wastewater treatment methods. Since it utilizes natural vegetation and rhizosphere microorganisms, it is eco-friendly method of treating sewage. An important factor to be considered is the aesthetic improvement that is provided by this methodology. No mosquitoes and odour nuisance The treated water can be used for enhancement of environmental architecture such as roadside fountains. The quality of treated water is comparable to irrigation standards TREATMENT EFFICIENCIES Phytorid system being natural method, the final efficiencies as indicated in Table 1, will be achieved after the system is stabilized which may require a period of 6 months after commissioning. Table 1: Performance of PHYTORID for urban waste Pollutant Performance (% removal) Total suspended solids 75 – 95 Biochemical oxygen demand 70 – 80 Chemical oxygen demand 60 – 75 Total nitrogen 60 – 70 Phosphate 50 – 60 Fecal coliform 85 – 95 Quality of Treated Water: The treated water will meet the quality suitable for gardening purpose. OPERATION AND MAINTENANCE This technology is natural system; as a result operation is mostly passive and requires little operator intervention. Requirement for area can change on various factors such as load (kg BOD/day), ambient temperature, topography of the region, flow characteristics, etc. Maintaining uniform flow across the Phytorid system through inlet and outlet adjustment is extremely important to achieve the expected treatment performance. Sampling of inlet and outlet will be carried out for a period of 3 months every fortnight after stabilization of the treatment systems for first one year.
