What is pH monitoring?

Within industrial wastewater sampling, pH is a measurement used to determine how acid or alkaline a substance is. pH levels are measured on a scale from 1-14, with values below 7 indicating acidity and values above 7 indicating alkalinity. pH is a critical component of wastewater makeup as its value has a direct impact on how it is treated. Even small changes in pH levels can pose serious environmental issues, as they can impact the health of biological systems and chemical dosing required so it’s essential that they are tested using accurate and robust equipment.

As a Partech partner, we offer highly accurate pH testing equipment to ensure consistently reliable results.

Partech 7300w² Monitor

Part of the WaterWatch² range, the 7300w² monitor allows for monitoring of a range of values including pH and turbidity and can comfortably accommodate up to eight sensors, with additional sensors a possibility depending on site capacity.

Partech says:

The 7300w² contains an inbuilt trending display, customer configurable, that shows the last 24 hours data for any measurement point on an easy to navigate graph. This can also be downloaded for reporting purposes. An external USB port and data logging function allows users to log and retrieve all stored data for a site in a standard .csv format without the need for specialist SD cards or compatible hardware.

Combining sensors provides a very cost effective way of simultaneously monitoring parameters such as dissolved oxygen and suspended solids in an activated sludge plant, or pH and turbidity at a treatment works outfall where the sensors can be located close together.

WaterTechw² pH8000 pH Sensor

The WaterTechw² pH8000 pH Sensor provides reliable and accurate results when measuring pH levels and temperature within industrial wastewater sampling applications.

Partech says:

The sensor uses a flat surfaced electrode which includes an extended reference path, these features combine to provide an extremely robust pH measurement, suitable for use in surface water, waste water and drinking water applications.

The electrode uses field proven flat surface, self-cleaning technology. The reference system is enhanced by the Extended Path Reference (ERP) design which provides a complex path to protect the reference in the presence of interacting ions such as proteins, silver and sulphides.

What is pH flow sampling?

Industrial wastewater sampling using pH flow sampling allows us to test the pH levels in wastewater to ensure it is correctly treated before being discharged to bodies of water.

Chemical contamination in wastewater can damage standard pH electrodes, so we recommend using a specialist pH glass combination electrode which produces a millivolt potential proportional to the pH – this is them amplified inside the pH instrument to give an instantaneous value.

pH flow sampling solutions

SIRIS offers a robust and cost-effective electrode system for the continual measurement of pH industrial wastewater sampling in open vessels such as tanks, sumps or pits – manufactured up to 3000mm in length to ensure that the pH is being measured at the correct point.

The pH electrode can be easily and quickly removed for periodic calibration and buffering. Ownership is low cost and replacement pH electrode inserts are affordable and simple to install.
