As a high-flux operation mode of thin film composite-forward osmosis(TFC-FO)membrane,active layer facing draw solution(AL-DS)mode suffers from the severe membrane fouling tendency,which is not addressed ***,we introduced a photocatalyst(Anatase titanium dioxide,A-TiO_(2))onto the support layer of TFC-FO membrane via the bonding of polydopamine(PDA)and polytetrafluoroethylene(PTFE),and prepared two photocatalytic membranes,A-TiO_(2)/PDA@TFC and A-TiO_(2)/PTFE@*** with the pristine TFC-FO membrane,both A-Ti O_(2)/PDA@TFC and A-TiO_(2)/PTFE@TFC had an improved water permeability(10.5 L m^(-2)h^(-1)and 9.5 L m^(-2)h^(-1),respectively)and reduced reverse Na Cl flux salt(0.8 g m^(-2)h^(-1)and 0.7 g m^(-2)h^(-1),respectively)in the AL-DS mode using 1 mol/L Na Cl as draw solution and pure water as feed ***,in the 16 h fouling experiment using 200 ppm bovine serum albumin(BSA)solution as a representative pollutant,the flux decline rate of both photocatalytic membranes was dramatically alleviated from 39.7%and 21.7%in the darkness to 8.5%and 9.7%under UV irradiation,respectively,indicating a significant anti-fouling capacity of photocatalytic *** all,the presence of A-TiO_(2)endowed membrane with high permeability,high rejection efficiency and excellent anti-fouling capacity under UV *** bonding agent,PTFE provided the modified membrane with a high photocatalytic effect and high self-cleaning capacity,while PDA increased the membrane permeability and protected membrane against photocatalytic *** work provides a simple and feasible method to improve the anti-fouling capacity of TFC-FO membrane in AL-DS mode.

Water budget closure is a method used to study the balance of basin water storage and the dynamics of relevant hydrological components(e.g.,precipitation,evapotranspiration,and runoff).When water budget closure is connected with terrestrial water storage change(TWSC)estimated from Gravity Recovery and Climate Experiment(GRACE)data,variations in basin runoff can be understood *** this study,total runoff variations in the yangtze River Basin(YRB)and its sub-basins are examined in detail based on the water budget closure *** compare and combine mainstream precipitation and evapotranspiration models to determine the best estimate of precipitation minus *** addition,we consider human water consumption,which has been neglected in earlier studies,and discuss its *** evaluate the effectiveness and accuracy of the combined hydrological models in estimating subsurface runoff,we collect discharge variations derived from in situ observations in the YRB and its sub-basins and compare these data with the models’final estimated runoff *** estimated runoff variations suggest that runoff over the YRB has been increasing,especially in the lower sub-basins and in the post-monsoon season,and is accompanied by apparent terrestrial water loss.
