在海水淡化过程中，藻华会导致膜污染。高压反渗透 （RO）膜受到通过膜的产酸有机物（AOM）的影响 预处理。当预处理技术为低压微滤（MF）或 超滤（UF），它被AOM和藻类细胞严重污染。AOM在大小上是不均匀的 因为藻类在自然细胞溶解过程中或通过泵和阀门中的剪切作用被分解。这个 这项工作的主要假设是，一定尺寸的AOM是污染最严重的。 长凳- 规模试验表明，在高压和低压过滤中， 尺寸在0.22至2µm之间的颗粒AOM往往是表面上高度污染的部分 目前大多数应用中使用的膜。生物高聚物的吸附几乎没有影响 颗粒物质不存在时的污染可能性。包括15个参考文献、图表。

Algal blooms cause membrane fouling in seawater desalination. High-pressure reverse osmosis (RO) membranes are affected by algogenic organic matter (AOM) that passes through pretreatment. When the pretreatment technology is low-pressure microfiltration (MF) or ultrafiltration (UF), it is severely fouled by AOM and algal cells. AOM is heterogeneous in size because algae are broken apart during natural cell lysis or by shear in pumps and valves. The main hypothesis of this work is that a certain size class of AOM is the most highly fouling. Bench-scale experiments revealed that in both high-pressure and low-pressure filtration, particulate AOM between 0.22 and 2 µm in size tends to be the highly fouling fraction on the membranes currently employed in most applications. Adsorption of biopolymers had little fouling potential when particulate material was not present. Includes 15 references, figures.
