Rochem BioFilt — MBR Sewage Treatment

About

Rochem® BioFilt is a membrane bioreactor (MBR) system for black and grey water treatment. It uses proprietary Flat Sheet ultrafiltration modules in an oxygen-rich bioreactor to produce 94 to 97% clean waste water.

Overview

BioFilt may well be the most thorough sewage treatment system available for marine applications. As one of the world's best known yacht builders has confirmed: "if you are serious about keeping your guests' swimsuits white, it may be the only one that is fit for purpose."

Cleaning is straightforward and involves no smells or mess. You can leave BioFilt running at all times, including when guests are swimming around your boat. You can sail anywhere, including into marine sanctuaries restricted under the marine protection code MEPC 227(64) for protected areas.

BioFilt can be combined with a Rochem freshwater generator to reach German Trinkwasser drinking water specifications, identical to those used on German Navy ships.

Scalable from small yachts up to 1,000 passengers or more.
