In-Pipe Monitoring of Water Quality Parameters

s::can (Austria) and Hawle have developed a new solution for monitoring water quality parameters in the distribution network. With the Hawle sensor adapter the i::scan probe can be directly mounted in pressurised water pipes.

The i::scan is a miniature spectrophotometer that is not much more expensive than a good turbidity meter, but can measure up to four parameters online in real-time, all within a single instrument. Measurable parameters include turbidity, organics (e.g. TOC or COD), colour and UV254.

The i::scan uses a new light source technology which leads to reduced costs and only needs minimal maintenance. Due to its low power consumption (typically less than 1 W) it can be easily powered by solar panels and used in unmanned stations. 

The proven Hawle technology allows drilling of all kinds of water pipes under pressure. This makes it possible to mount the i::scan without any interruption to the water supply and also allows for easy maintenance access for the i::scan.
