TREATMENT OF PIGGERY ANAEROBIC DIGESTATE LIQUID USING WOODCHIP BIOFILTERS

摘要

The Nitrates Action Plan [1] has restricted the amount of land area suitable for the landspreading of pig manure. Treatment of the separated liquid fraction of pig manure would greatly reduce the volume of manure to be landspread. The solid fraction of the pig manure can be retained and used as a nutrient rich fertiliser or as a substrate for creating compost and fuel.
