This study examined the use of modified palm oil fuel ash (POFA) prepared from agricultural waste as key material for fabricating the POFA hollow fibre ceramic membrane (PHFCM) to trap arsenite, As(III), and arsenate, As(V), from water. In this study, the ozonation technique was employed where the effects of pre- and post-ozonation on the adsorption capacity of PHFCM and fouling mitigation were investigated respectively. The highest sintering temperature of 1150°C (PHFCM-11500) delivered maximum adsorption capacities that corresponded to 95.62 and 98.34 mg·g⁻¹ of As(III) and As(V). PHFCM-1150 with sufficient mechanical strength (52.84 MPa) and excellent pure water flux (250.73 L/m².h) were selected for further exploration with ozonation study. Pre-ozonation increased the adsorption performance while the fouling problem of PHFCM was successfully treated by post-ozonation. Additionally, the post-ozonation treatment offers a cost-effective application of PHFCM-1150 with only 3 min of optimum reaction time that enables the integrated reuse of the sorbent, with the practical and effective removal of As for industrial effluent/wastewater treatment. This study also demonstrated that PHFCM-1150 was effective and its respective As removal met the maximum discharge limit of 10 μg/L set by the World Health Organization and the national legislation in Malaysia.

本研究中使用从农业废物制备密钥材料用于制造POFA中空纤维陶瓷膜（PHFCM）以捕获砷，改性棕榈油燃料灰（POFA）的作为（III），和砷酸盐，如（V），从水。在这项研究中，采用臭氧化技术，分别研究了臭氧化前和臭氧化后对PHFCM吸附能力和污垢缓解的影响。最高烧结温度1150°C（PHFCM-11500）的最大吸附容量相当于95.62和98.34 mg· g ^-1的As（III）和As（V）。选择具有足够机械强度（52.84 MPa）和优良纯净水通量（250.73 L / m ² .h）的PHFCM-1150进行臭氧化研究，以进行进一步的研究。预臭氧化提高了吸附性能，而后臭氧化成功解决了PHFCM的结垢问题。此外，臭氧化后处理提供了具有成本效益的PHFCM-1150应用，最佳反应时间仅为3分钟，从而使吸附剂能够集成再利用，并且能够切实有效地去除As用于工业废水/废水处理。这项研究还表明，PHFCM-1150是有效的，其各自的砷去除量达到了世界卫生组织和马来西亚国家立法所设定的最大排放限值10μg/ L。
