In order to reduce the impacts on sludge treatment facilities caused by impurities such as fibers, hairs, plastic debris, and coarse sand, an innovative primary sludge pretreatment technology, sludge impurity separator (SIS), was proposed in this study. Non-woven micromesh with pore size of 0.40 mm was used to remove the impurities from primary slu...

... Pseudomonas aeruginosa into artificial wastewater to achieve biofouling, they revealed that the build-up of higher cell counts and biofilm thickness, especially for the dead cells, led to an adverse impact on the retention of PhAC; however, the higher concentration of extracellular polymeric substances on the membrane surface in the later stage of biofouling resulted in an increase in PhAC retention. & An innovative sludge pretreatment technology proposed by Mei et al. (2018) enable effective impurities removal from primary sludge using non-woven micromesh. & Zhang and Li 2017 highlight the feature of low-organiccontent sludge digestion, and explain its intrinsic mechanism of deterioration effect on energy recovery. ...
