It is advised that these devices be connected to the main raw water supply line as per Fig 1 above. Only in rare cases, if installation as per Fig 1 above is not possible, then it can be installed as per Fig 2 above. The valves used should be of the type that will not restrict the flow very much, such as ball valves or gate valves. During operation it will be necessary to take samples downstream of the unit to check the chlorine residual. The sample must be drawn after the chlorinated flow has merged with the bypassed flow. A sample tap might be installed for this purpose. In operation, the water flows by gravity through the bypass line (Fig 1) or in a pressurized bypass line (Fig2) through our units. In this arrangement adequately chlorinated water is mixed in raw water to have desired free chlorine. The dose should remain relatively constant regardless of the rate of flow. The chlorine dose so adjusted should be sufficient to satisfy the chlorine demand and provide a residual level in the distribution system. If it adds more chlorine to the water than is needed for these purposes, the chlorine dose can be controlled by the amount of water bypassing our unit. To increase or decrease the dose the bypass valve may be adjusted to divert more or less water through the unit. During operation the bypass valve will normally be partially or completely closed for flow control and the isolation valve will be partially or wide open. The valves once adjusted are seldom required to be changed for a site, unless there is a marked change in raw water parameters- viz flow rate. The technology has been supplied in more than 9000 units of different models in different States in India and abroad. The Technology has already Won many awards on National and International Front on its Innovative concept like ” the Most Innovative New Technology of the Year 2016″  at the World CSR Congress & Awards and the Golden Peacock Awards 2019 at Dubai, for Best New Technology in Water Disinfection.
