One year on Water Tecnik take a look back at Mauds Ice Creams installation

One year on Water Tecnik take a look back at Mauds Ice Creams installation of a Turnkey Effluent Treatment System & the results!

NI Water perform regular trade effluent sample analysis, to ensure the various parameters on the sewer discharge consent agreement, on parameters of COD (chemical oxygen demand), SS (suspended solids) and PH are adhered to. More recently NI Water have added FOG (fats oil and grease) to the discharge consent agreement, at a limit of 100mg/L.

Mauds business had grown substantially since their site was built in 2000 and the current grease trap system was not providing enough effective control of the fats, oils and greases, meaning Mauds were struggling to achieve the target of 100ml/L.


Water Tecnik Supplied and installed a complete turnkey effluent treatment system for Maud's. From electrical and mechanical installation, right through to commissioning and customer training, all tasks were completed directly by Water Tecnik, ensuring continuity for our customer throughout the project.

Results include,

  • 40% reduction in COD (chemical oxygen demand) *
  • Through our efforts jar testing the incoming effluent we identified a more cost effective treatment regime. This lowered chemical costs by 49%.
  • 80% reduction in SS (suspended solids).
  • 96% reduction in FOG (Fats, Oil and Grease) - went from 650mg/L to 26mg/L.

*remaining COD is due to the high levels of dissolved sugars present in ice cream production effluent.


Mauds Ice Creams are now fully compliant with all discharge consent limits, and this project has proven to be a huge boost to the continual environmental improvement plans for their business

Since installation Mauds have signed up a service, maintenance and chemical supply agreement with Water Tecnik. We look forward to our continued working partnership with Mauds Ice Creams.
