Treatability study of whey processing effluent was undertaken in a single stage ultrafiltration pilot plant using a commercial hydrophilic polyethersulfone flat sheet membrane. The pure water permeability of the membrane was found to be 1.065 × 10^-7 m³/ (m².s.kPa). The flux of permeation was observed to decrease steadily at all pressures and the maximum flux was recorded to be 10.42 × 10^-6 m³/m²s at 2.94 × 10² kPa after around 15 minutes of operation. The initial and final characteristics of dairy wastewater sample were determined in the form of pH, BOD, COD and TDS at an ambient temperature. The BOD, COD and TDS removal were found to be 44 %, 64% and 38% respectively. The results, thus obtained underscore the importance of ultrafiltration as a supplement to the existing wastewater treatment processes.

使用亲水性聚醚砜膜在超滤中试工厂中乳清处理废水的可处理性

使用商业亲水性聚醚砜平板膜在单级超滤中试工厂中进行了乳清加工废水的可处理性研究。膜的纯水透过率发现是1.065×10 ^{- 7}米³ /（米² .s.kPa）。观察到渗透的通量在所有压力下稳定地降低，并且最大通量被记录为10.42×10 ^{- 6}米³ /米² s的2.94×10 ²操作约15分钟后的kPa。在环境温度下以pH，BOD，COD和TDS的形式确定乳制品废水样品的初始和最终特征。发现BOD，COD和TDS的去除率分别为44％，64％和38％。由此获得的结果强调了超滤作为现有废水处理工艺的补充的重要性。
