A Northampton based Waste Recycling company was evaluating membrane technology to replace an old DAF system which was treating landfill leachate at a site in North Lincolnshire.

The requirement was to establish a system that could handle the specific site conditions at the same time meet the local water discharge requirements.   Axium Process was contacted to help evaluate the suitability of membrane filtration for this particular site and conduct a series of pilot trials using one of our membrane filtration test plants to process the sample leachate taken from the actual site.

The results were highly successful and enabled the selection of the optimum membrane suited to the North Lincolnshire site conditions.  Our engineers  designed  and built a self-contained ultrafiltration system which was used to treat around 140,000 litres of landfill leachate per day.  Because the system did not  require the use of  dosing chemicals and was designed for minimal maintenance, the company also benefitted from significant cost savings in terms of reduced down time and disposal costs.

Membrane filtration is a proven technology in the treatment of landfill leachate as it can dramatically reduce the COD (-85%) and suspended solids content (-100%) typical of leachate effluent.

Ultrafiltration of leachate enables extended digestion of solids and provides a controlled discharge flow. The process requires no dosing chemicals resulting in significant cost savings.
