Aluminium‐based drinking water treatment residual (Al‐DWTR) has been used as an emergent substrate in laboratory‐scale and pilot‐scale biofiltration systems (biofilters and constructed wetlands) for its good affinity for phosphorus (P) adsorption. However, there is a concern about whether the P adsorption process will contribute to substrate clogging. Two laboratory‐scale up‐flow biofiltration systems were set up to identify the contribution of the P adsorption process to clogging under various operation conditions.

磷吸附会堵塞基于矾泥的生物过滤系统吗？证据和见解

铝基饮用水处理残留物（Al-DWTR）由于对磷（P）的吸附具有良好的亲和力，已被用作实验室规模和中试规模的生物过滤系统（生物过滤器和人工湿地）中的新兴底物。但是，人们担心P吸附过程是否会导致基质堵塞。建立了两个实验室规模的上流式生物过滤系统，以识别P吸附过程在各种操作条件下对堵塞的贡献。
