Scale Inhibitors
Scaling within reverse osmosis (RO) systems is a serious matter. Not only does scaling drastically reduce system performance, but the abrasive scale deposits may also cause irreversible damage to the rejecting membrane surfaces.

Cleaning Spiral Wound Membranes
All reverse osmosis (RO) systems foul over time. Symptoms of fouling include a decrease in normalized permeate flow, an increase in salt passage, or an increase in differential pressure.

The Role of Coagulants in Reducing Colloidal Fouling
Micromedia filtration (MMF) is the most economical means of removing colloids from within reverse osmosis (RO) feedwater. However, to be effective, in-line coagulation is required upstream of the filters. With coagulation, colloid removal rates of 95% to 99% are typical.
