  Advance in UF module The latest offering of ultrafiltration systems from Evoqua Water Technologies (Alpharetta, Ga.; www.evoqua.com) incorporates an advanced polyvinylidene fluoride (PVDF) membrane into a hydraulically balanced, modular filtration system. Known as Memcor CPII, the product employs a PVDF membrane with a uniform, but asymmetric morphology that forms a dense, permeable “skin” layer over an open substructure. The membrane allows high permeability with good abrasion resistance and can achieve less than 5% flow variance among the filtration units, says Russ Swerdfeger, product manager for Memcor at Evoqua. The membranes are used with optimized modules that are assembled in up to 32-unit racks. The racks are very compact and easily accessible to minimize the footprint, reduce installation costs and simplify system operations. The new CPII system is being deployed as a pretreatment strategy for reverse osmosis units, and boiler feedwater. Improved pinch analysis Last month, the national PinCH-Center of the Lucerne University of Applied Sciences and Arts (HSLU: Switzerland; www.hslu.ch/tevt) introduced PinCH 2.0, a new version of its pinch-analysis software, which is now able to optimize processes with either…
