DIHALOGENO-HYDROXYDIPHENYLETHER AS ANTIMICROBIALS IN WATER TREATMENT |
摘要 |
<p>The use of dihalogeno-hydroxydiphenyl ethers as antimicrobial agents in water treatment processes, such as in purification and decontamination of drinking or waste water, is claimed. Preferably the water treatment is performed in a membrane filtration system. The antimicrobial agents protect the membrane system against bacterial and/or algal decay and assist in maintaining a high efficiency of the membrane filtration process. Methods of maintaining membrane filtration efficiency using dihalogeno- hydroxydiphenylethers as well as aqueous antimicrobial rinsing liquors comprising dihalogeno-hydroxydiphenylethers are also claimed.</p> |
