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.

Self-cleaning filters

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.

Automatic filters

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.

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.
