摘要
添加阻垢剂是反渗透系统重要的预处理方法之一,但膜在运行中还是会被反渗透过程中沉淀出的不溶性物质所逐渐污染。为了克服污染,必须对膜进行的定期清洗。反渗透市场上每年都会推出新的清洗剂,如何评价这些反渗透清洗剂及销售商提供的清洗程序至关重要。文章提供一种快速、方便、可靠的膜清洗剂试验方法。
One of the most important pretreatment of RO is dosing antiscalant, but membrane is fouled gradually by sparingly insoluble salts scaled in the reverse osmosis process. To overcome membrane fouling problems, periodic cleaning of the membrane must be implemented. The RO market yearly creates new types of special cleaning agents for RO plant. RO plant operators and technicians must evaluate these antiscalants on laboratory bench-scale before use in real plant to study the maximum possible water recovery that a certain dosage inhibitor can attain and the correct level of dosing. This paper tested a fast, simple and reliable laboratory technique.
