Abstract: The present disclosure provides systems and methods that can treat feeds with elevated organic levels, e.g., feeds with ?300 Pascals (Pa) organic osmotic pressure, with one or more enhanced filter membrane modules, which may be referred to herein as membrane modules or simply modules. Preferably, a filter membrane module consistent with the present disclosure include one or more plate and frame modules, one or more spiral format modules, or a combination of plate a frame and spiral format modules. The systems and methods provided herein can provide reliable performance when used to treat feeds with elevated organic levels.

Abstract: The present disclosure is directed to filtering technologies that combine elements of continuous and batch NF/RO based on the constraints of the end-user facility to achieve a target balance between, for instance, recovery and power consumption, and to reduce long term operating cost of a plant. A method for extending batch operation into a second induction period with antiscalant injection is also disclosed herein, with the second induction period allowing for yet higher water recovery.
