  • Tank Mixing & Spray Aeration Helps Stop "Flushing For DBP / THM Compliance"

    Disinfection By-Products (DBPs) can be very difficult to remove in certain areas of a water system especially dead-end & low demand areas where water can sit for an extended period of time. In the case of trihalomethanes (THMs), the longer water sits, the more THM formation potential there is. Many systems have had no other alternative but to flush out the old water and replace with more ...

  • Effect of first flush on storage-reliability-yield of rainwater harvesting

    Rainwater harvesting (RWH) entails capture of rainwater falling on a roof and conveyance to a storage tank for later use as domestic water supply. During dry weather, dust and pollutants accumulate on the roof surface and are subsequently washed off with the ‘first flush’ at the beginning of the next rain. Diverting the first flush can improve the quality of stored water but at the cost of ...
