Case History In Optimizing Filtration
To Reduce RO Fouling| PDF
File (1629 KB)
A large utility in the southeastern
U.S. originally installed RO’s in 1994 and had experienced
fouling problems since the first day they were put online.
The RO’s would require weekly cleanings, sometimes
after just 3 or 4 days of operation. Based upon a successful
Streaming Current installation and a Particle Detection
study performed at another utility site, Chemtrac was
invited to look at what could be done to help the new
plant resolve their RO fouling problem. |

Chemtrac's
Treatment Control System model TCS 4000, optimizes coagulant
dosage for water treatment systems using clarifiers, direct
filtration, flotation units, etc... The system responds
to change in raw water flow, solids concentration (turbidity),
color, etc... and automatically maintains the proper coagulant
feed rate. |
