Construction Starts on the World’s Most Expensive Leachate Treatment Plant

Construction has started on the world’s most expensive leachate treatment plant which at $27 million will be the most expensive ever built in the world to date.  A number of plants are estimated to have been built at up to $15 million previously, but this one is significantly the most expensive in terms of the […]

The Principle of Reverse Osmosis Applied to Leachate Treatment

When leachate must be treated to a very high standard for watercourse discharges which require not only for the reactive components of leachate to be removed but also require non-reactive compounds to be removed such as the sodium chloride, which is always elevated in MSW landfill leachate, the technology of Reverse Osmosis may be the […]

How a Membrane Bioreactor is Used to Treat Landfill Leachate

In principle, a membrane bioreactor combines biological treatment with a separation process using microfiltration membranes. A Membrane Bioreactor consists of a reactor tank and a microfiltration unit. In the reactor, the micro-organisms (mostly bacteria) transform dissolved polluted matter into biomass, and ammoniacal nitrogen (“ammonia”) into nitrate. Thus biodegradable organic pollutants are eliminated by the bioreactor […]
