Traditional membrane manufacturer wet testing procedures typically utilize a NaCl
solution at a specific concentration and applied pressure at a standard operating temperature
and percent recovery. The Deep Aquifer Treatment System (DATS), an 8-mgd (30280m3/day)
nanofiltration (NF) plant utilizes a negatively charged, organic selective membrane that was
specifically manufactured to remove natural color causing organics with low salt rejection. As
part of the performance criteria, the membrane was wet tested for color removal at the
manufacturer's facility. The paper presents an overview of this test along with membrane
selection process, previous piloting results and startup and performance testing of the full scale
DATS facility. Water quality issues (silt density index (SDI) and methane gas) experienced
during startup and methods to overcome them are highlighted.
