GT-Reactor Technology-Intelligent dosing system, developed from the whole system perspective, is a professional reagent recipe and process technology to control the membrane fouling. This technology use specific reagent recipe for different water quality, prevent the membrane fouling, decrease the chemical cleaning frequency, and even cancel the off-line chemical cleaning. Membrane system is recovered through backwashing, thus the lifetime of the membrane could be lengthened, and the operation efficiency of membrane system is increased.
