Polyethersulfone　(PES),　polyvinylidene　fluoride　(PVDF),　and　polyacrylonitrile　(PAN)　were　prepared　to　purify　micropolluted　source　water　via　a　pilot-plant　test.　Integrative　devices　of　in-line　coagulation/ultrafiltration　(UF)　were　proposed.　Then　the　treatment　performance,　operation　stability,　clean　methods,　and　fresh　water　recovery　rate　were　assessed.　The　results　showed　that　the　membrane　materials　and　operational　modes　did　not　result　in　significant　difference　of　the　removal　efficiency　of　turbidity,　CODMn,　and　NH4-N.　The　uniform　distribution　porosity,　better　hydrophilicity,　and　higher　thermal　stability　of　the　PES　membrane　made　its　specific　flux　(SF)　more　than　double　those　of　two　other　membranes;　in　addition,　the　transmembrane　pressure　(TMP)　of　PES　membrane　appeared　to　be　the　least　influenced　by　temperature　change.　The　hydrophilicity　of　UF　membrane　was　not　a　conclusive　factor　with　the　critical　flux.　The　inside-out　module　with　higher　fouling　load　presented　higher　decay　rate　of　SF　under　fixed　flux　operation　compared　with　outside-in　modules　in　single　filtration　duration.　The　way　of　gas　washing　of　outside-in　modules　as　a　supplement　resulted　in　recovery　improvement.　The　acid-base　staggered　method　of　inside-out　module　to　carry　out　chemical　enhanced　backwash　(CEB)　can　effectively　intensify　the　effects　of　backwashing　by　water.
