North British Distillery: Anaerobic Digestion Plant

North British Distillery: Anaerobic Digestion Plant




Project Overview

The North British Distillery Company Limited undertook a major sustainability project to install a state of the art Anaerobic Digestion & Water Treatment plant. The project was split into three phases:

Phase1 comprised development of a process to mix process condensate and distillery spent wash to provide a conditioned feed in terms of pH and temperature suitable for treatment in a new Anaerobic Digestion (AD) Plant.

Phase 2 was to expand the AD process and to install a water treatment plant to clean the AD effluent allowing approximately 40% of the water to be recycled with the remainder being discharged to the local sewer.

Phase 3 was to install a gas engine to produce electricity from the biogas produced by the AD reactors
