*4 This value is just a reference value and not a guaranteed value of Toray. Sustainable operating filtration
flow capacity varies among the plant depending on the type of wastewater, total process design, and
operating condition. In case of industrial wastewater application, it is strongly recommended to conduct
a pilot test before membrane tank designing.
