Sulphate monitoring for wastewater effluent
Explore online measurement options for industrial wastewater and final-effluent applications, with support from PMA on method and installation.
Choose a method around the sample
Sulphate occurs naturally in water. Elevated concentrations can also be associated with industrial discharge, making monitoring relevant to some effluent control programmes.
The monitoring requirement, sample matrix and site conditions should guide the analyser selection.
Optical and electrode approaches
Sulphate is commonly measured by an optical turbimetric method. Where background turbidity makes an optical measurement difficult, an ion-selective electrode approach may be considered. PMA can discuss which method is appropriate for your site.
Products for this application
Two online analyser routes are shown below. The suitable choice depends on the measurement method, sample and operating arrangement.
3S sulphate analyser
A compact, programmable online colorimeter for sulphate monitoring in industrial water applications.
Discuss your effluent monitoring point
Tell PMA about your discharge objective, sample turbidity, site arrangement and service requirements. Our team can help you assess the measurement route.
