反渗透运行污染的化学清洗

Chemical Cleaning of Reverse Osmosis Contamination

介绍了化学除盐水站反渗透技术的应用情况,针对反渗透在运行过程中出现的无机物结垢、胶体颗粒物沉积、微生物的滋生、化学污染等问题进行了分析,提出了解决方案。通过定期对其进行化学清洗,提高了反渗透膜的运行寿命。

The application of antipenetration technology at chemical desalting water station is introduced in the paper. Problems such as inorganics scaling,colloidal particle sedi-ment,microorganism growth,chemical contamination and etc. at reverse osmosis running are analyzed and solutions are proposed. The service life of reverse osmosis membrane is prolonged by periodic chemical cleaning.
