Greencore Food to Go are the world's largest pre-packed sandwich manufacturers, with eight facilities for this section of the business in the UK.

Due to the nature of the business, the untreated waste water from Greencore Food to Go contains fats, large vegetable solids, grains, etc.

A full trade effluent treatment plant was installed, which includes a screen filter, balancing tank, DAF unit, pH control and correction, chemical supply and dosing and all necessary equipment.

Suspended solids levels across the plant are massively decreased from over 3800mg/L to a range less than 100mg/L, with resultant savings of over £800 per day.

The site also benefits from monthly service visits, which includes the sampling and analysis of the waste water both before and after treatment, examination and inspection of equipment, recommendations for optimisation and advice on how to maximise efficiency with the treatment plant as a whole.
