Ultrafiltration membrane bioreactor
Koch has announced its PURON® MBR ultrafiltration membrane bioreactor series, ideal for industrial wastewater treatment to reduce energy, minimize downtime and increase flux in a cost-efficient manner. This patented module features reinforced polyvinylidene fluoride hollow fibers that are fixed only at the bottom, virtually eliminating the buildup of hair and fibrous materials. Solids and particulates, including bacteria, remain on the outside, while permeate is drawn through the membrane to the inside of the fibers. PURON systems have a low energy demand, and the robust braided membrane fibers of the modules lead to minimal downtime and breakage.

Dual treatment system
Aqua-Aerobic's Aqua BioMax dual treatment system is ideal for low-flow applications involving, for example, construction sites and industrial wastewater. Combining rotating biological contactor (RBC) technology with cloth media filtration, the unit utilizes multiple RBC disks that are vertically-mounted and closely spaced on a steel shaft, providing a large surface area for bio film growth. The disks rotate out of the wastewater to provide aeration for efficient biological oxygen demand (BOD) removal and nitrification. A cloth media drum filter follows the RBC to collect and remove the biological solids prior to the effluent discharge.

Water treatment plant
The Trident® HS package water treatment plant from WesTech provides multi-barrier protection for difficult-to-treat surface water, groundwater, industrial process water, and tertiary wastewater. The Trident system design consists of packaged high-rate settling, adsorption clarification, mixed media filtration, and optional ultraviolet disinfection. These innovations allow the Trident to handle very high raw water turbidity and solids loading and achieve total organic carbon reductions of up to 70% or more. In addition, all of these benefits can be achieved with a nearly 50% reduction in waste production.
Bernoulli System's multi-basket self-cleaning BMG-range filters reduce a number of elements in natural water sources and protect sensible process equipment from clogging and fouling. By using multiple smaller filter baskets in one filter body, the systems offer fine filtration down to 100 microns, even at large capacities. The filters serve as pre-filters and act as an additional protection for finer filtration technologies such as ultrafiltration and multimedia filtration. With desalination, they also act as pre-filters before reverse osmosis. The filters are used in power generation, petrochemicals, steelmaking, pharmaceuticals, pulp & paper, and food & beverage.
The Amiad SAF Series includes sophisticated, easy-to-operate, automatic filters, with a self-cleaning mechanism driven by an electric motor. The filters support flow rates of up to 400 m³/h (1,760 GPM), with various screens designed to cover a range of 800-10 micron filtration degrees. Further, they are available in inlet/outlet diameters of 2" to 10". Raw water enters the filter inlet through the coarse screen, which protects the cleaning mechanism from large debris. The water then passes through the fine screen, trapping dirt particles that accumulate inside the filter. Next, clean water flows through the filter outlet.

Membrane brine concentrator system
Oasys Water's Membrane Brine Concentrator (MBC) System, a complete forward osmosis offering, is a solution for high-salinity industrial wastewater that uses membranes and the principles of osmosis to separate water from salt and other dissolved solids at a fraction of the energy and cost of traditional evaporation. The MBC system can desalinate 4,000 barrels of water per day and is ideal for the oil and gas industry where it can achieve up to 85-percent water recovery, discharging brine of concentrations up to 25 percent salt.
AXEON SDF-Series Sediment Depth Filters are available in 2.5" and 4.5" diameters and provide an economical option for numerous pre- and post-filtration applications. SDF cartridges can be used as a single stage of filtration for particulate reduction or as an integrated stage of filtration within a water treatment system. These filters are engineered to create an outside-in flow that allows the outmost layer to capture larger-sized particles and the inner layer to capture the stated micron rating of the filter. In addition, the trapping of various-sized particles layer-by-layer provides a high dirt-holding capacity.

Drum screen system
The Screenmaster RT internally-fed drum screen from Franklin Miller employs a rotating drum to provide effective fine screening of a variety of materials. The unit's cylindrical screen is constructed of perforated stainless steel, wedgewire or filter cloth. As the material is fed into the unit's inlet, it is distributed along the internal screen surfaces by a weir, which moves the solids along the screen length as the drum rotates. The liquids are then discharged out the unit's bottom, and the solids are conveyed to the unit discharge flange. Drums up to 60" diameter and 156" (4 m) length are offered.
