这项工作报告使用硅藻土（DE）废物和有机粘合剂来自黄麻，当地称为“Mrenda”的设计中的一个有效的水过滤膜。加入炭粉以提高膜的孔隙率。烧制在700.0 °C至1150.0 °C的温度下进行。DE废料样品的SiO2质量分数为79.0%，总熔剂质量分数为11.0%，而Porter's粘土的SiO2质量分数为50.0%，Al_2O_3质量分数为28.8%，总熔剂质量分数为7.0%。另一方面，“Mrenda”粘合剂含有6.5%的总有机物质。使用的植物来源的粘合剂的机械强度提高了52.7%的生坯和152.2%的烧制膜。制造的DE废物为基础的膜比粘土为基础的陶瓷膜在类似的条件下制备的强15.0%。900.0 °C的烧结温度对于生产每小时过滤4.1升水的多孔膜是最佳的。由DE废物制造的膜的孔径仅在2.0 nm-99.0 nm之间。在微生物过滤效果方面，DE废液基膜和活性炭质量分数为5.0%的DE废液基膜对大肠杆菌的去除率分别为99.9%和88.4%。大肠杆菌和轮状病毒。
This work reports on the use of diatomaceous earth (DE) waste and organic binder derived from Corchorus olitorius, locally known as “Mrenda” in the design of an efficient water filtration membranes. Charcoal powder was incorporated to enhance the porosity of the membrane. The firing was done at temperatures varying from 700.0 °C to 1150.0 °C. The DE waste samples comprised 79.0% silica (by mass) and 11.0% total flux content compared to porter’s clay that had 50.0% silica, 28.8% AL_2O_3 and 7.0% total flux content. On the other hand, the “Mrenda” binder contained 6.5% total organic matter. The use of the plant-derived binder enhanced the mechanical strength of the greenware by 52.7% and the fired membranes by 152.2%. The fabricated DE waste-based membranes were 15.0% stronger than clay-based ceramic membranes prepared under similar conditions. A sintering temperature of 900.0 °C was optimal in producing porous membranes for filtering of 4.1 liters of water per hour. The pore diameter of the membranes fabricated from DE waste only ranged between 2.0 nm–99.0 nm. On micro-organisms filtering efficacy, the DE waste-based membranes and those fabricated with 5.0% charcoal were 99.9% and 88.4% effective in the removal of E. coli and Rotavirus respectively.
