The present study examines the efficiency of modified bone char (BC) with C–MgO nanoparticles (MBC-C–MgO) as media in a cartridge filter as an antibacterial agent to produce a new filter. The filters were operated in a continuous mode using a pre-static pump. MBC-C–MgO were produced and modified with sucrose through the co-precipitation method. The microbial quality of effluent water samples was compared with commercial refrigerator cartridge filters using a heterotrophic plate count (HPC) test and SEM analysis. The results showed that the effluent water from the filter with MBC-C–MgO media had the lowest HPC (177 CFU/mL) compared to bioceramic (271 CFU/mL) and carbon (500 CFU/mL) under similar experimental conditions after 4 months of operation. Maximum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests were determined using the broth dilution method on Escherichia coli (ATCC 25922) and Enterococcus faecalis (ACC 29212). The MIC results for E. faecalis and E. coli were 156.25 and 312.5 µg/mL, respectively. Furthermore, the MBC results for E. faecalis and E. coli were 312.5 and 625 µg/mL.

The experimental results obviously showed the antibacterial properties of C-MgO nanoparticles and the MBC-C-MgO.

本研究研究了使用C-MgO纳米颗粒（MBC-C-MgO）作为盒式过滤器中的介质作为抗菌剂生产新过滤器的改性骨炭（BC）的效率。过滤器使用静态泵以连续模式运行。MBC-C–MgO是通过共沉淀法生产并用蔗糖改性的。使用异养板计数（HPC）测试和SEM分析，将出水样品的微生物质量与商用冰箱盒式过滤器进行了比较。结果表明，在相似的实验条件下，经过MBC-C–MgO介质过滤后的废水在4个相似的实验条件下具有最低的HPC（177 CFU / mL），而生物陶瓷（271 CFU / mL）和碳（500 CFU / mL）最低。运营数月。大肠杆菌（ATCC 25922）和粪肠球菌（ACC 29212）。粪肠球菌和大肠杆菌的MIC结果分别为156.25和312.5 µg / mL。此外，粪肠球菌和大肠杆菌的MBC结果分别为312.5和625 µg / mL。

实验结果清楚地表明了C-MgO纳米颗粒和MBC-C-MgO的抗菌性能。
