UF membranes for O&G, iron and solid removal before electrodialysis reversal (EDR) in a commercial produced water desalination application CASE STUDY PolyCera ® Titan Overview • Reuse and recycle of oil and gas produced water constitutes a new frontier of desalination. Traditional salt removal technologies such as reverse osmosis (RO) and electrodialysis reversal (EDR) have been impractical in this application without reliable pretreatment. Conventional oil-field pretreatment processes do not have the ability to sustain a consistently low-level of free oil & grease, iron, turbidity and SDI in their effluent. • A produced water treatment facility in Central Wyoming, USA, was seeking a process solution to consistently and dependably treat their produced and fracking water to meet
