超滤

超滤(UF)是一种低压膜工艺,通过尺寸筛分去除悬浮物、胶体、细菌及绝大多数病毒,广泛用于饮用水澄清以及反渗透的前处理。

在处理流程中的作用

UF provides an absolute physical barrier to particulate and microbial contaminants without chemical coagulant doses that sedimentation requires, producing consistent low-turbidity filtrate regardless of feed swings. It does not remove dissolved salts or small organics, so it is paired with RO/NF when demineralization is required.

As RO pretreatment, UF delivers a stable, low-fouling feed that extends membrane life — a pairing standard in modern desalination and reuse plants. Hollow-fibre UF is manufactured at large scale by suppliers including Litree, Toray and DuPont.
