 en Factors that Can Interfere with Virus Concentration from Wastewater when Using Zeta Plus 60S Filter Membranes
APS Queiroz; FM Santos; CM Hrsi; JMG Candeias; TA Monezi & DU Mehnert


Zeta plus filter membranes (ZP60S) have been shown to be efficient for rotavirus concentration from wastewater and for the reduction of cytotoxicity for cell cultures. Recently a variability in both properties was observed. In view of the low costs and the high virus recovery rates obtained in the past, we re-evaluated the application of ZP60S filter membranes for virus concentration from environmental samples. Some factors that could interfere with the concentration strategy using ZP60S were also considered and assessed including the type of water to be filtered and the possible release of toxic substances from the membrane matrix during filtration.

rotavirus, cytotoxicity, positive charged membranes
