Membrane-Based Technology for Landfill Leachate - Waste and Recycling - Landfill
While this class of wastewater typically requires several treatment steps, high performance membranes are at the heart of meeting stringent discharge regulations including zero liquid discharge (ZLD) applications. In fact, RO membranes are the only treatment technology that can consistently provide high quality treated effluent, even if the feed varies.
In the table, we show the performance of a ST+ RO membrane landfill leachate treatment system. Per the process diagram, the leachate was acidified and then mechanically prefiltered before being fed to a two-stage ST+ system. Excellent permeate quality results from this RO membrane process.
The AquaZoom™ reverse osmosis membrane module technology has been used in more than 81 landfill leachate treatment installations over the last 10 years.
With your flow, feed quality, and discharge requirements, we can recommend the membrane and module configuration to meet your needs. Talk to us about your situation and we can help optimize overall throughput and membrane performance.
