2) Kubota

Permeate without SS

The membrane separation system removes not only SS but substances difficult to biodegrade such as detergent, by taking advantage of its longer SRT (Sludge Retention Time). Nutrients such as nitrogen and phosphorus can also be cleared. This enables the treated water to be re-used.

Simple Maintenance

Volume control of return sludge or microscopic observation of the microorganism is not necessary. All that is required control of trans-membrane pressure and basic water analysis, both of which can be easily learned. Telemetry is easily applied.

Energy Conservative Operation

KUBOTA Submerged Membrane Unit system is designed for energy conservation. Aeration plays two roles to save energy; oxygen supply for biological treatement and cleaning of membrane surface with turbulent flow.

Remarkably Small Footprint

KUBOTA Submereged Membrane Unit is installed in an aeration tank. Since it carries out high-concentration activated sludge treatment, no settling tank or sludge concentration tank is required. The size of the aeration tank is also minimized.
