Stormwater filter
The ClearWater BMP is a stainless steel filter train design that allows storm water flows to be screened, triple settled, and then filtered, all within the confines of an existing concrete curb inlet drain box. The design significantly reduces concentrations of trash, sediment, hydrocarbons, metals, and nutrients. Testing from San Diego State University established that the unit will remove 97% of TSS, 86% of hydrocarbons, 83% of zinc, and 81% of lead.

Filter vessel
Parker-Hannifin has introduced the new ParMax™ Filter Vessel, a high-flow capacity filtration solution for municipal water systems and other liquid applications. The filter vessel combined with ParMax™ Select filter cartridges can reduce the overall cost of filtration when compared to vessels containing traditional 2.5" diameter filter cartridges by yielding high-flow rates with fewer cartridges in a smaller, lower-cost vessel.

Differential pressure transmitter
The Ashcroft® Model GC52 is a compact wet-wet low differential pressure transmitter, ideal for measuring pressure drop across filters and membranes. With the push of a button, the GC52 can also provide direct flow readings by measuring dp across a deliberate restriction. Available in uni-directional ranges from 0-4 to 0-400 Inches W.C. and bi-directional ranges up to 200 Inches W.C., the GC52 operates on line (static) pressures up to 300 psi. A rugged aluminum NEMA 4X / IP65 enclosure measures only 2.56" in diameter and incorporates an LCD display for local reading.

Filtration systems
Orival now provides complete water filtration systems designed for specific municipal and industrial applications. These systems include filters, manifold, valves and control. The ORG and OR series of automatic self-cleaning filters are designed to withstand the day-in and day-out rigors of POTWs. A wide range of filters are available from ¾" to 24" and filtration degrees from 5 to 3000 microns. Many of the company's filter models demonstrate low pressure loss, occupy minimal footprint, use only a few gallons of water for cleaning and need no electrical power to operate their cleaning mechanism; thus requiring less energy than conventional treatment methods.

Submerged membranes
iSep™ ultrafiltration (UF) membranes from TriSep were designed specifically for some of the most difficult and aggressive wastewater applications. Their key design feature is the integration of the UF membrane and process tank into a single module. The encapsulated membrane design allows for frequent draining, reducing fouling as all solids are easily purged from the system.

Filter pilot unit
The new MD-4 Cloth Media Pilot Unit is a fully enclosed, 53 foot, drop deck trailer. At its core is a 1-disk Aqua MiniDisk® cloth media filter with several aesthetic, operational and functional upgrades providing greater flexibility for each unique customer application. The MD-4 unit includes a fully equipped lab area with the ability to accomplish on-site analysis for most operating parameters such as total suspended solids monitoring and particle size analysis.

Cartridge filters
Hurricane filters from Harmsco Filtration separate dense solids prior to cartridge filtration for extended filter life, increased dirt holding capacity and reduced maintenance costs. Components include an outer chamber for particle separation, inner chamber for cartridge filtration, and built-in drain for purge, if required. Deep angled pleats are directed toward rotational flow for increased dirt holding capacity. The rational flow improves the filter's performance.

The WesTech SuperDisc™ is an efficient microfilter provided in either stand-alone stainless steel tanks or for installation into concrete tanks. Filtration is achieved down to 10 micron with separation efficiencies of up to 98 percent. Applications include effluent polishing of wastewater, raw water filtration, water reuse, process water filtration, and cooling water filtration, among many others. Raw water is guided into the rotor drum and flows by gravity into the filter discs. The water then passes outward through the filter media on the attached radial disc sectors.

Compressible media filter
The Schreiber Fuzzy Filter® is a high rate, compact, modular filter applicable to a wide variety of water and wastewater applications. The filter uses a nominal 30" deep media bed comprised of individual 1.25" diameter compressible synthetic fiber spheres, and achieves a high rate of solids removal down to 4 microns. The total porosity of the filter bed can be mechanically altered to suit influent characteristics by mechanically compressing the media.

Flat-bottom flume filter
Although a Leopold® FilterWorx® filter can be arranged with a front flume, center flume or H flume to achieve the best layout, the Leopold Flat-Bottom Flume® Filter is offered as a new design. The FBFF arrangement allows substantial cost savings in excavation and support structures. The magnitude of these savings can be greatly amplified where poor subsurface conditions, such as rock or groundwater, exist. The flat-bottom flume features a completely flat floor in new construction or certain existing situations.

Disc filter
The woven polyester pleated panel design of the Forty-X™ disc filter from Siemens Water Technologies provides increased treatment capacity and an ultimate barrier for suspended solids in tertiary treatment processes. The pleated media design increases the true cloth area available for filtration by 40% over flat panel designs. This assures a more sustainable operation in terms of throughput, better feed distribution and fewer backwash cycles.

Membrane bioreactor
Based on its existing Airlift™ Membrane BioReactor (MBR) technology, Norit X-Flow developed a new modular concept for municipal wastewater treatment, the Megablock. The pre-fabricated modules minimize plant engineering, on-site construction and help reduce total installed costs. The system is composed of modular sections, each consisting of 36 ultrafiltration (UF) membrane modules that can be expanded to a maximum of six sections for a total of 216 modules per unit.
