2025-09 PHOSPHORUS PROCESS ANALYZER

The Town of West Warwick is seeking bids for a Phosphorus Process Analyzer for the West Warwick Regional Wastewater Treatment Facility. The analyzer should be able to measure total phosphorus concentration in a sample using the molybdenum blue colorimetric method. The system should have a measurement range of 0.05 to 10 mg/l and be able to provide multiple 4 to 20 mA analog outputs. The analyzer should also have a configurable program for automated cleaning of the internal systems and contain a supply of cleaning solution. • The analyzer should be a digestive, colorimetric/photometric device with integral transmitter/electronics. • The system should be capable of sampling up to 10 ppm with direct sampling and up to 50 ppm with an integral dilution system. • The analyzer should have a standard one-year warranty period from the date of shipment and a labor warranty of one-year from the date of final installation. • The analyzer should be able to extract a sample from an open vessel or bypass line with a low solids content and particle size less than 800 µm. • The analyzer should have remote access to measured values, configuration, and diagnostics through an optional integral ethernet-based web server.
