The use of a ceramic membrane is not only a new and modern technique, but reduce the use of chemicals and coagulants as well, and also having high mechanical and chemical resistance reduces costs over consecutive years. The aim of this research was to remove turbidity and biological agents such as Diatoms, Chlorophyte, Cyanophyceae, Protozoa, and Nematodes by using of ceramic membranes. A ceramic pilot plant was designed and constructed. Titanium oxide (TiO) and aluminum oxide (AlO) ultrafiltration membrane with the length, diameter and pore sizes of 25 cm, 2.7 cm, and 50 nm was used. The inlet flow was the effluent resulted from the backwashing of a sand filter. This data showed that the possibility of removing of this agent was high by comparing the size of the agents and ceramic membrane pore size. Therefore, the construction of a pilot plant of ceramic membranes with 50 nm pore size and dimension ( = 1.5 m, = 20 cm, = 50 cm) was offered a constant flow filtration, and sampling was performed at different times. The results showed that all biological agents except diatoms have a removal efficiency of 100% and the effluent׳s turbidity was 0.1 NTU.
使用陶瓷膜不仅是一种新型的现代技术，而且还减少了化学药剂和凝结剂的使用，并且其高机械和化学抗性在连续几年中降低了成本。本研究的目的是通过使用陶瓷膜去除浊度和生物制剂，如硅藻、绿藻、蓝藻、原生动物和线虫。设计并建造了一个陶瓷中试装置。使用了长度、直径和孔径分别为25厘米、2.7厘米和50纳米的氧化钛（TiO）和氧化铝（AlO）超滤膜。进水是砂滤器反冲洗产生的出水。通过比较生物制剂的大小和陶瓷膜孔径，该数据表明去除这种制剂的可能性很高。因此，提供了一个孔径为50纳米、尺寸为（长 = 1.5米，宽 = 20厘米，高 = 50厘米）的陶瓷膜中试装置进行恒流过滤，并在不同时间进行采样。结果表明，除硅藻外，所有生物制剂的去除效率均为100%，出水浊度为0.1 NTU。
