Abstract: By using high-voltage discharge technology and capacitance effect, the electrode rod can make colloidal particles in water increase the particle potential instantly, increase the surface charge density, and improve the mutual repulsion between particles in water. This can prolong the operation cycle of reverse osmosis membrane device and improve the production efficiency. During the abnormal operation period, the operation time of RO with electrode rod is twice longer than that without electrode rod; during the stable operation period, the RO with electrode rod produces 19.65% more reuse water than that without electrode rod.

Key words: electrode rod, reverse osmosis (RO) device, wastewater reuse
