Most Filmtec™ brackish water elements are cleanable over a wider range than most competitors elements (1-13 pH) which allows better lifespan and performance on tough surface waters. BW30XFR elements from Filmtec™ offer superior salt and silica rejection for industrial process waters including any pretreatment of EDI or mixed bed ion exchange equipment. Many elements are now available wih iLEC™ end caps which reduces the possibility of o-ring leakage that can negatively affect permeate quality.
