Grime Scene


Following on from the successful Grime Scene competition, we have decided to continue the theme for another year, but with a twist. This year, we are asking for photographs of the grimiest pictures you can find accompanied with another photograph of how the ‘scene’ has been improved by your maintenance or cleaning.

We will display the photographs in each of the Waterline editions throughout 2024. The ‘most improved’ picture will be chosen by WMSoc members via an online vote. The winner will receive a £25 Amazon Gift Voucher after the Winter 2024/25 edition has been published.

Product & Service Spotlight

Secondary disinfection options from B & V Chemicals:

We can offer our customers several secondary disinfection options to control issues like biofilm formation and harmful bacteria proliferation

Genox or chlorine dioxide
For water usage above 60m³/day, we recommend installing either a chlorine dioxide unit or a Genox unit. The Genox units generate hypochlorous acid from brine electrolysis with running costs as low as 4.0 pence/m³.

Ultralox 40 or SuPerSil
For smaller systems, continuous dosing with Ultralox 40, a hypochlorous acid solution, is a cost-effective alternative with few safety risks.
Similarly, silver peroxide dosing suits low to medium water usage systems.
