Membrane Fouling Reduction Field Test Plan - Processing Shale Gas Flowback and Produced Waters
The purpose of the pilot test is to compare the operational parameters of coated and uncoated UF and RO membranes while processing pretreated oilfield frac flow-back and produced waters. The coated membranes utilize Advanced Hydro fouling
resistance coating technology.

Pretreatment is provided the Fountain Quail water recycling facility and comprises the following steps:
pH adjustment up to 10.0 – 10.5 with caustic soda (NaOH) to cause partial softening via precipitation of CaCO3. This also causes a reduction in TSS via the coagulation effect of the precipitated solids.
Addition of anionic flocculant to enhance settling of precipitated/coagulated solids
pH adjustment down to 3.5 – 4.0 using HCl to stabilize the treated water to minimize downstream scaling.
