摘要： Provided is a clogging resistant biofilm-based water treatment system. The system includes a membrane-enclosed water flow pathway including at least one water-impermeable, oxygen-permeable membrane wall portion extending along the pathway and at least another wall portion extending along at least part of the pathway. According to the subject matter provided, biofilm growth and consequent clogging generally takes place along the water-impermeable, oxygen-permeable membrane wall portion and biofilm growth and clogging does not take place along the another wall portion.

摘要： The present disclosure provides a water treatment module, a bioreactor comprising one or more of such modules and a receptive water treatment system. Also provided herein is a method making use of the above module, bioreactor and system. The water treatment module comprises (i) at least one elongated gas enclosure comprising a gas inlet and two vertical walls, at least one vertical wall comprising a water-impermeable and gas-permeable membrane having a water-facing side and a gas-facing side, the two vertical walls separating between water external to the enclosure and gas within the enclosure, the gas enclosure being in a rolled or folded configuration to thereby define a convoluted horizontal path and one or more water-treatment spaces formed between opposite water facing sides of the enclosure; and (ii) a diffuser arrangement comprising gas diffusers configured for introducing a stream of gas into the one or more water treatment spaces.
