The Girvan factory makes chocolate crumb: a key ingredient in chocolate manufacture. Nestlé UK is undertaking a programme of investment and capital works to reduce energy and water consumption.
SPS has been working with Nestlé's team over the last 18 months, providing a DAF plant on hire to assess its capability and suitability for load reduction for treatment of Girvan factory effluent.
The SPS D50 unit uses established solid and liquid separation technology to generate 'whitewater' by dissolving air under pressure and then releasing the pressure to form microfine air bubbles.
Solids and other particulates attach preferentially to the air bubbles and rise to the surface of the DAF unit where they are collected, thickened and removed by a motorised scraper. The treated water can then be reused or discharged offsite as necessary, while the collected material can be disposed of via recycling routes. This process ensures that companies meet discharge consent compliance and incur reduced disposal charges.
