Landfill Leachate
You manage the world's waste; we'll help you keep it from impacting the world's water.Helping landfills better manage their leachate.
Leachate can be nasty stuff. We can equip you with proven, easy-to-use technologies to keep it at bay. Whether you need to meet your municipal treatment plant’s requirements or the toughest environmental discharge permits, we have the solution.
Ready for your high-strength, highly-variable BOD, COD, and ammonia
The high levels of ammonia, Biological Oxygen Demand (BOD), or Chemical Oxygen Demand (COD) in your leachate can be poisonous to receiving waterways or overload a municipal plant used to mostly household waste streams.
But high-strength and even highly-variable wastewater is no match for the BioPorts MBBR. It has a small, flexible footprint, so you won’t have a problem fitting it into your water treatment infrastructure, and it works by retaining more of the bacteria that treats the wastewater by growing it on plastic media retained within the basin, rather than just letting that bacteria wash out of the system with the cleaned water. (It also makes your aeration more efficient by breaking up the bubbles as they rise, and typically enables you to use low-maintenance coarse bubble aeration.)
Even in freezing water, you can treat ammonia to <1 mg/L
In cold climates where leachate may reach temperatures as low a 1ºC (34ºF), most traditional forms of treatment slow down to a crawl, meaning you either have to store your leachate through the winter or risk surcharges, fines, even an ecological and P.R. nightmare. Unless you have a SAGR for leachate treatment.
You can treat ammonia to <1 mg/L and polish BOD/COD to <10 mg/L in near-frozen water with a SAGR. It achieves this impressive feat by using the time when the water is warm to pre-grow the necessary bacteria that will treat the water when its cold. No more storing through winter, and you’ll sleep easy without worries about surcharges, fines, or worse.
