KUBOTA Submerged Membrane Unit® has microfiltration membranes rather than ultrafiltration membranes. Kubota’s membrane pore size decreases the amount of energy required to pull water through the membrane, this allows flexible filtration options that ultrafiltration membranes cannot support. KUBOTA Submerged Membrane Unit® filtration can be driven by Siphon alone (gravity option), pumps, or a combination of the two (Pump Assisted Gravity Filtration for peak hydraulic loads). Kubota MBR system can decrease operational costs by using only Siphon filtration if six to ten feet of water head are available at the proposed site.
Membrane materials have different affinities to water. Membranes with low hydrophilicity have to be stored at low temperatures in hydrophilic agent for immediate use. KUBOTA Submerged Membrane Unit® comes pre-treated with a hydrophilic agent and can be used either immediately upon arrival or after storage.
