PAH Monitor for Water Effluent
PAH Monitor for Water Effluent
(OP)
As I mentioned in BTEX thread, looking to monitor PAH online for an industrial wastewater treatment control loop.
Water will be filtered so oil and grease/TSS or not a concern. Monitor should be cyanide/sulfide resistant.
PAH conc. 0-100 mg/L. Any recommendations?
Measure of BTEX in ppm range would also be a welcome bonus.
Plant scale is ~0-10 m3/h ~ 40 USGPM.
Thanks.

RE: PAH Monitor for Water Effluent
What sort of process plant discharge applies?
What regulations apply?
Where is the water sampled, etc.?
I think that there is lots on the web but I have not looked for PAH. Check the EPA or other standards and methods such as EPA Methods 610, 8270C or 1625 (referenced in some articles).

'Oil in water' analyzers seems to be a broad category that include BTEX and PAH components.
As you mentioned PAH can be measured offline using HPLC/GC (APHA methods).
Online methods seem to use UV-fluoresence.
