The Watemark PDF and Older Versions

The Watermark was originally conceived as a way of sharing technical tips, new product launches and projects from each department within Automated Water & Effluent Since 2007 we've been circulating copies of The Watermark to our customers and constantly surprised at the positive feedback we receive from people.

Technology is always moving on so we like to keep our customers up to date with recent developments. There are some technical tips that are timeless - so we've kept a full archive of each Watermark we've sent out listed below available as a PDF.

The Watermark for Spring 2018 is now available to read online.

In the Spring 2018 issue of The Watermark we have a special feature on how to introduce reliable lime dosing to a pH correction system.

We also has have a brand new Temperature Controller - the SRT73 which is ideal for use with PRT devices such as a PT100 or PT1000.

Finally - we take a look at dosing pump spares, so that we can avoid unnecessary downtime and just keep on pumping.
