The FLOTAMET™ process consists of a mixed anaerobic reactor, GWE’s ANAMIX™, followed by a sludge flotation – GWE’s SUPERFLOT™ – GAS. Anaerobic sludge separation via flotation works particularly well in applications with high suspended solids (TSS) and/or fats, oils and grease (FOG) concentrations or with salt-rich wastewaters. It is suited for wastewaters with COD values up to 100,000 mg/l and even higher, and can handle single waste streams or a combination of several.
In the ANAMIX™ reactor portion of the FLOTAMET™, the actual anaerobic treatment takes place. This is a completely mixed reactor, equipped with an agitation system to prevent sludge settling or flotation. Dissolved and suspended organic matter is largely degraded by anaerobic bacteria (sludge) and converted into biogas. As it is an anaerobic process, very little sludge growth takes place during this process, ensuring a minimal amount of waste sludge to manage.
