MBR system

The Titan MBRTM system marries the wastewater treatment engineering expertise of Smith & Loveless with Flat-Plate Membranes. Submerged in the aeration section of the MBR tank, the Flat-Plate Membrane - rated at the microfiltration level - maintains high permeability and flux rates even at peak-day rates. Because the system employs air scouring to prevent fouling, it does not require back-pulsing or the associated equipment and chemical costs typical of other systems. Because of its robust support, flat-plate units also experience less wear and tear than hollow-fiber types and can be cleaned in place. The MBR systems come in standard and custom designs, and result in smaller footprints than conventional systems. The submerged membrane eliminates clarifiers and sand filters while still producing significantly better effluent quality.

NF, RO membranes

Koch Membrane Systems has received certification of compliance with NSF/ANSI Standard 61 for nanofiltration (NF) and reverse osmosis (RO) elements. These elements include the Fluid Systems® TFC®SR®2, TFC-S, TFC-HR, TFC-XR and TFC-ULP® spirals, in sizes from 8" to the industry-leading 18" diameter MegaMagnum® RO elements. Certification was provided by NSF International. The newly certified MegaMagnum elements provide significant economies of scale and reduced space requirements for water treatment facilities. A single 18" x 61" MegaMagnum spiral element contains 2,800 square feet of membrane surface area, compared to 400 square feet in commonly deployed 8" x 40" products.

Turbidity monitoring

The Clarity II, available from Emerson Process Management, offers low level accuracy ensuring precise measurements of turbidity levels for filter bed monitoring. This measurement ensures compliance with either EPA or ISO approved reporting requirements. Operators can choose from single- or dual-channel sensor input. The dual channel design enables two sensor channels to be monitored simultaneously with independent ranges and analog outputs.

Optimizing pretreatment systems (clarifiers, filters, etc.) is the key to maintaining performance of downstream equipment such as Reverse Osmosis. Chemtrac’s streaming current monitors help optimize the addition of coagulants prior to filtration. The particle counter, Model PC2400D, and particle monitor, Model PM2500, provide a level of on-line, continuous, monitoring not achievable with SDI (silt density index) or turbidity measurement.

JWC Environmental’s Bandscreen MonsterTM, part of the Monster Separation SystemTM, screens wastewater to remove problem solids and provide protection for membrane bioreactor treatment plants (MBRs). The 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 2 mm openings lift the unwanted solids out of the channel to prevent them from clogging MBRs.

Amiad offers the new MT-44, a 200 gpm, 3 micron, automatic, self-cleaning, string-wound cartridge filter. The filter was developed using the same thread, plastic material and overall dimensions of the previous cassette. However, this release is made of a stronger construction and a denser thread stacking, which has reduced the diameter of the pores and improved its filtration capabilities.
