2025-12-08 – Weekly Water Treatment News : Portable turbidity meters for 24/7 use

Last week, our community was buzzing with discussions about both the technical and practical aspects of water treatment. Members shared insights on the latest tools and technologies, debated the merits of various treatment methods, and offered advice on regulatory compliance. One hot topic was the ongoing challenges of managing contaminants like PFAS, particularly in relation to new plant designs. Another recurring theme was the importance of reliable equipment for continuous monitoring.

Feel free to explore these discussions and contribute your expertise. Here’s to another week of learning and sharing.

I’ve been running a portable (Hach 2100Q) on 24/7 rounds; keep dedicated, scratch-free cuvettes per site and stash desiccant packs in the case — foggy optics will “invent” NTU at 3 a.m., and like @maria_r says, “trust but verify” with a 0 and mid-range check before the night shift. If you’re seeing drift with temperature swings, let the meter sit for 5 minutes to equilibrate; it’s like a bathroom scale — move it and it lies. For continuous alarms, an inline low-flow turbidimeter can shoulder the load while the handheld stays for grab confirmations.

Quick example: ‘zero + 1 NTU’ check before rounds; cold temps skew readings — pre-warm the meter or insulate.
