Testing with Hanna Instruments to ensure compliance
Coating Systems, Inc. must adhere to stringent requirements and meet Industrial Discharge Permit regulations. The wastewater parameters that are frequently treated and tested for at this facility include copper, nickel, zinc, and chromium. The final pH that is discharged is continuously checked as well. Coating Systems, Inc. depends on Hanna Instruments Dual-Channel Universal Process Controller (HI520) to easily monitor and control pH/ORP automatically. Prior to using Hanna Instruments, Coating Systems, Inc. struggled to collect consistent ORP readings with the controllers that were utilized at the time. ORP results were always off by a zero. For example, if the controller displayed an ORP reading of “25”, then the actual correct ORP reading would be “250”.
Reliable results at critical facility checkpoints
After switching to Hanna Instruments Process Controllers for their facility, Coating Systems, Inc. was able to achieve more precise pH/ORP readings. This provided greater visibility into wastewater parameter levels and improved effluent management. With exact pH/ORP measurements, Coating Systems, Inc. was better equipped to make the necessary pH adjustments for zinc treatment and rectify pH and ORP fluctuations for chrome.
“Hanna’s availability and willingness to reach out and provide on-site assistance has been a plus.”
- Frank Getek, Waste Treatment Manager, Coating Systems, Inc.
In addition to Process Controllers, Coating Systems, Inc. regularly tests with Hanna Instruments Portable Field pH/ORP/ISE Meter (HI98191) to spot check pH/ORP levels in the quality lab or on the production floor. The versatility and durability of this meter paired with its accuracy, make it the perfect fit for the industrial applications Coating Systems, Inc. performs.
“Changing out a probe is very straight forward. We have only had to replace the pH probes once a year at most. The probes are calibrated monthly.”
- Frank Getek, Waste Treatment Manager, Coating Systems, Inc.
