The Aqua-Aerobic® MBR process specifically uses a unique time-managed, sequential aeration process to promote biological nutrient removal within a simplified unit process. The integration of Puron® submerged membranes, manufactured by Koch Membrane Systems, provides direct filtration of high-level MLSS. In comparison to conventional membrane bioreactor (MBR) technologies, the MBR process offers advantages by addressing equalization, nitrification and denitrification within a single reactor while minimizing power costs through reduced energy needed for mixing, pumping and aeration. The process is ideal for end users who require high quality treated water for water reuse.

The UF Membrane System from Miller-Leaman is designed to remove suspended particulate, bacteria, colloidal, and high molecular-weight contaminants from source water. Target industries/applications include wastewater, reuse water, municipal, textiles, pulp & paper, pharmaceutical, plastics, and electronics. The system is ideal for pre-filtration of RO membranes. Filtering between 0.1 and 0.01 microns, the system provides high quality effluent water, removing all total suspended solids with more than a 95% recovery ratio and producing output water turbidity of less than 0.4 NTU. The system operates at less than 22 PSI, reducing energy costs compared to other systems. It has an integrated Maxim controller for backwashing. Triggered by the trans-membrane pressure, the air-pulse-actuated backwash cycle will remove suspended solids from the outside membrane surface, therefore extending the time between chemical cleaning cycles. Systems can be manifolded to meet any flow rate and come complete on a stainless steel skid with variable frequency drive pumps.

MBR system

The Titan MBR™ marries the wastewater treatment engineering expertise of Smith & Loveless with Flat-Plate Membranes. Submerged in the aeration section of the Titan tank, the Flat-Plate Membrane 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 easily 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. Flow capacities range from 5,000 gpd to 3 mgd. The system will meet effluent requirements of less than 3 mg/L BOD, 1 mg/L TSS, 2 mg/L TKN, and 1 mg/L NH3. Cleaning is in-place and is typically accomplished on a semi-annual basis in about four hours.

IMAS™ (Integrated Membrane Activated Sludge), available from Ashbrook Simon-Hartley, provides membrane quality effluent, while minimizing capital and operating costs by individually optimizing the performance of the biological and membrane filtration unit processes. BOD and TSS reduction, nitrification, denitrification and phosphorous removal are all easily achieved to meet current and anticipated future discharge limits. The ultra-low membrane fouling environment inherent in the process allows high membrane flux, low energy and chemical consumption and a compact footprint. The system uses SpiraSep spiral wound membranes.

The Trident® HS system is a multi-barrier packaged membrane treatment unit that addresses the Long Term Enhanced Surface Water Treatment Rule and other regulations. A high-rate, two-stage clarification system removes both settling and non-settling solids while providing built-in redundancy. After clarification, treatment is completed with an integral media filter and UV disinfection unit. Since its introduction in 2005, the system has proven its effectiveness at reducing turbidity, color and TOC in surface water supplies. The unit also can provide pretreatment for NF/RO high pressure membrane systems. The two-stage clarifier may be used to provide micro- or ultra-filtration membrane pretreatment. In addition to drinking water treatment, the Trident HS design is ideal for ultra-low-level phosphorus reduction and water re-use for wastewater applications.

The Title 22-approved DynaLift™ MBR system from Parkson combines out-of-basin ultrafiltration tubular membranes with a simple biological wastewater treatment plant to produce high-quality effluent. The biological process is a long-sludge-age design that provides excellent BOD removal and nitrification. Anoxic and anaerobic zones are added as needed for nutrient removal. Increased mixed liquor concentrations mean more biological treatment capacity within the same footprint. Long sludge age treatment results in less waste sludge production, excellent process stability, low membrane fouling and lower overall operating costs.

The Muni-Disk® cloth media wastewater filter manufactured by Municipal Filtration Co. combines patented gravity flow hydraulics and unique cloth media technology to eliminate pumps, drive motors, chain gears, backwash/sludge manifolds, and other complicated mechanical wear items, resulting in a simple yet effective tertiary treatment system. The system uses a combination of differential head and a series of open-close pneumatic valves to provide wastewater filtration and backwash flow control in a compact package. Cloth panels are locked in place during normal operation – which reduces mechanical complexity and maintenance issues – but can be removed from the flow stream for media replacement while influent flow continues to other online elements. Vertically placed cloth media panels reduce equipment footprint and the modular design simplifies expansion for future flow increases. Standard stainless steel packages range in capacity from 400,000 gpd to 2.5 mgd.
