Approved Rate - Supply, delivery, erection and commissioning of following capacity of micro processor based water disinfection equipment using Silver Ionization process based on Oligodynamic technology, suitable to provide directly to pumping main, or to sump or to overhead tank, with bypass arrangements, controlling valves, microprocessor based control panel, in built transformer, relay miniature circuit breaker, tool kits, spares etc. The water chambers are made of corrosion free stainless steel confirming to SS 304 investment casting, capable to withstand a pressure of 10 Ksc with inbuilt electrodes mounted on a powder coated (mild steel) cabinet of 20g thickness with universal lock and key for safety. The control panel will have Electrode active indication to show that the water is flowing inside the chamber, and the electrode is working, and Change Electrode indication to show that electrode is nearing completion, for easy maintenance of the equipment. The control panel will have two dosage modes of Low dosage and Normal dosage. Low dosage will give 0.005mg/lit of silver and Normal dosage will give 0.01mg/lit of silver. The dosage can be adjusted by press of a button. The flow rate setting can be adjusted by pressing increase/decrease buttons in steps of 250 LpH or 500LpH. The silver ions produced by the electrode will be totally nontoxic as permitted by BIS standards and the residual effect of the disinfectant will be long lasting for more than 2 days. The equipment is powered by a single phase 220V /50 HZ power supply and provided with an onsite disinfectant analyzing kit with consumables to do a minimum of 10 tests. An evaluation of efficacy of Silver Ionization Equipment for disinfection of drinking water from CSIR NEERI must be provided. The product should be tested and analyzed by CSIR NEERI and should have given a final report of its performance. The disinfection equipment must have constant current technology so that it can work well in both summer and winter and it should be endorsed by CSIRNEERI. The product must be purchased from manufacturers having CSIR NEERI appraisal only and not any dealer or agent, so that the guarantee of the product can be full filled. The product should have residual protection for minimum 48 hours and it should be endorsed by CSIR NEERI. The test kit provided by the manufacturer must be endorsed by CSIR NEERI.(APPROVE RATE ) 3000 LPH
