| Abstract: | It was analyzed that ZeeWeed500d of uhrafiltration membrane appeared problem of the membrane flux reduction resulted from scaling in operation. In order to prevent the blockade from the sealing and improve the flux, the aeration frequency was changed and the pH adjusted properly. The scaling on membrane made from polypropylene was cleaned effectively by ultrasound wave of frequency in 70-620 kHz. |
