Online Turbidity Monitoring in Water Treatment
Author: Zhejiang Weilan Technology Co., Ltd.Source: Official sitePublished: Category: Technical Articles
Summary: Turbidity analyzer principles, range selection and typical applications in plant water, membrane protection and effluent monitoring.
Turbidity is both an aesthetic and a microbial-risk surrogate parameter.
Principle
90° nephelometry per ISO 7027 / EPA 180.1 dominates. The low range (<1 NTU) demands high-quality optics.
Applications
- Plant finished water: <0.5 NTU (or <0.3 in some standards)
- Membrane breach warning on sudden spikes
- WWTP effluent SS compliance
Selection & Care
Match sensor to range; mount away from vibration and light with easy bubble removal; calibrate with standards. See our turbidity analyzer.
