We are happy to announce the completion of our membrane plant ORP analyzer project in Coral Springs, Florida. Coral Springs Improvement District (CSID) performs a routine maintenance program on their raw water production wells using high concentrations of sodium hypochlorite (chlorine). While the chlorine is flushed to waste after being used, CSID desired to have an Oxidation Reduction Potential (ORP) analyzer installed as a fail-safe to shut down the membrane system if a high ORP (indicating the possible presence of chlorine) is detected. The passage of such could damage the nano-filtration membranes. Globaltech was requested to provide and install the ORP analyzer.
Disinfection Control & Cost Efficiency
The new ORP was inserted directly into the raw water flow stream by using a tapping saddle and an insertion mount probe. New power and signal wiring were routed from the control room located in the membrane building to the new meter.
The new meter will assist in controlling disinfection and will detect potential oxidants like chlorine that could damage the thin film material located in the membrane cartridges. Chlorine damage to the membranes can lead to lower salt rejection and poor quality permeate, which in turn could result in costly membrane replacement and down time.
Programming modifications were made to the Supervisory Control and Data Acquisition (SCADA) system to provide alarm and automatic shutdown of the treatment system if a potential hazard were to occur.
