POLLUTION PREVENTION MEMBRANE WITH PROTECTIVE NET
PROBLEM TO BE SOLVED: To provide a pollution prevention membrane with a protective net capable of preventing sticking of pollution to a membrane surface of the pollution prevention membrane via contact between the membrane surface side and the protective net, and capable of preventing damage of the pollution prevention membrane and reduction in water permeability caused by sticking the pollution, by installing the water permeable protective net on the membrane surface side of the pollution prevention membrane.SOLUTION: For preventing diffusion of pollution, a water permeable protective net 3 is installed on the membrane surface side of a pollution prevention membrane 1 installed in the water (b) of fresh water or seawater.SELECTED DRAWING: Figure 1
【課題】汚濁防止膜の膜表面側に通水性の保護ネットを取り付けることにより、膜表面側と保護ネットとの接触を通じて、汚濁防止膜の膜表面に汚濁等が付着するのを防止でき、汚濁等が付着することに起因して汚濁防止膜の破損や透水性の低下を防ぐことのできる保護ネット付き汚濁防止膜を提供することにある。【解決手段】汚濁の拡散を防ぐために淡水又は海水の水中ｂに設置される汚濁防止膜１の膜表面側に通水性の保護ネット３を取り付けた。【選択図】 図１
