Sanitaire has launched a new membrane bioreactor (MBR) solution for municipal applications. The dual stage system uses the company’s experience and expertise in diffused aeration and biological treatment, followed by a hollow-fiber immersed ultra-filtration membrane. This combination offers low operating costs with exceptional effluent quality in a compact footprint. Lower overall operating costs are achieved by optimizing the aeration and membrane systems individually which in turn reduces energy consumption and chemical usage.

Membrane antiscalants

Koch Membrane Systems offers its Kochtreat® antiscalants, a line of membrane pretreatment products. Formulated to prevent scaling and inorganic fouling, the antiscalants are ideal for enhanced operation of reverse osmosis (RO) systems producing potable water or high purity industrial water. A preventative maintenance program with using the antiscalants reduces membrane cleaning requirements and improves system performance. Koch Membrane Systems developed the antiscalants to be compatible with thin film composite and cellulose acetate RO membranes.

JWC Environmental’s Bandscreen Monster™, part of the Monster Separation Systems™, screens wastewater to remove problem solids and provide protection for membrane bioreactor treatment plants (MBRs). The unique inside-out flow pattern captures solids on the inside loop of the screen to prevent the bypass of solids, and the rotating perforated panels with 2mm openings lift the unwanted solids out of the channel to prevent them from clogging sensitive MBR systems.
