Optimizing filter backwashing
Optimum filter performance has become a critical component of surface water treatment. For conventional and direct filtration systems, LT1ESWTR requires the combined filter effluent turbidity be less than or equal to 0.3 NTU’s for 95% of the readings taken each month. At no time may the readings exceed 1 NTU. As regulations change and filtration is pushed toward the lower limits of turbidity measurements, excellent filter operations with optimum backwashing techniques are needed.
