In November 2014, PWNT, in partnership with METAWATER and MPU, started a one-year pilot study of ceramic membranes directly on the water from Lake Michigan. This unit includesdequipment for pre-coagulation and a ceramic micro filter with a single, full-scale 269 sqft (25 m2) membrane module.
The key pilot results are:
- Very stable operation (i.e., cleaning only every >10 months) at an operational flux of 175 lmh.
- CeraMac® performed extremely well in combination with pre-coagulation for Lake Michigan water.
- No ozone was cleaning treatment necessary – standard cleaning chemicals worked well.
