FilmTec, a subsidiary of The Dow Chemical Company, has introduced the new Filmtec™ LP-4040 membrane element, designed to operate at low pressure in commercial applications. The element allows commercial systems to deliver high-quality water at low-pressure operation. It replaces many "first generation" low-pressure membrane elements and will purify more water in older systems, especially those operating with cold feed water. At the same time, FilmTec has improved the flow of its other 4040-size elements.
High rejection membranes
Hydranautics has introduced the new CPA2-HR (Composite Polyamide) High Rejection membranes to its line of ultrapure water treatment products. The new 365 ft2 membrane provides the highest salt rejection of any standard element available. The high rejection membrane will save up to 20% on the cost of downstream ion exchange polishing while providing a robust membrane suitable for surface water treatment. The 99.7% nominal salt rejection (99.6% minimum) membrane provides 10,000 gallons per day of ultrapure water. The elements are 8 inches in diameter and 40 inches long. They can be used as either a stand-alone product or part of the company's Integrated Membrane Solution™ (IMS).
The Mars Co. Fabricated Spools, Meter Test Spools and Fittings come in many sizes, lengths and configurations and can also be custom designed and fabricated to meet specific needs. By providing a precise fit, corrosion resistant coatings such as epoxy or nylon, excellent strength and short laying lengths, they work well in any application.

Membrana-Charlotte announces the release of GasCAD™ version 3.0 used for sizing Liqui-Cel Membrane Contactors. The sizing program has been used for more than 8 years to accurately predict Liqui-Cel Contactor system performance for the removal of oxygen and carbon dioxide from liquids. The program also provides vacuum pump sizing and sweep requirement information. Manufacturing improvements, additional application testing and 10 years of active system installations supported the decision to update the regression used in sizing various Liqui-Cel Contactor Systems. The contactors are used for adding or removing O2, CO2 and N2 to or from liquids in the Semiconductor, Power, Pharmaceutical, Photographic, Food and Beverage, and many other general industries.
Acidic wastewater treatment
Green Turtle Technologies has developed a new technology to treat acidic wastewater that combats the problems associated with current treatment systems. Known as PHIX, it is designed to treat acidic wastewater in process and/or prior to discharge into a water body or municipal sewer system. The pH is adjusted to within by-law limits or specific levels if required, resulting in by-law compliant sewer discharges. The system offers a flow-through design, small footprint, low maintenance, no requirement of control devices. It has been designed to allow better control over the effluent pH, and to do so with the use of an all-natural and safe media that eliminates the need for special storage or handling required by traditional hazardous caustic chemicals.

Self-cleaning water filter
Orival Filters protect heat exchangers and prevent clogging of nozzles, tubes and other narrow passages by removing dirt particles down to micron size, of any specific gravity, from once-through and recirculating cooling water systems. Line pressure powered, the filter cleans itself without external power, and does not interrupt system flow. Available from 10 to 10000 gpm.
RootX foaming root control is designed to eliminate damaging root growth in pipelines. By simply adding water, the product creates a root killing foam which will reach to the top of the pipe where 90% of root growth occurs. It can be applied with existing sewer cleaning equipment or directly from the package.

New polymeric ultrafiltration (UF) membranes from PCI Membrane Systems extend the company's range of membranes to include the lower molecular-weight cut-offs required for a variety of industrial applications including effluent treatment. Encased in a stainless steel or plastic shroud, and crafted from polymeric PVDF material, the new 6-mm diameter FPT03 and FPT10 membranes are suited as replacement cores for the A5 module, while the new FPA03 membrane is produced as 12-mm tubular replacement cores for the A19 module. Both the FPA03 and FPT03 have a nominal molecular weight cut-off of 30 kD. Like the existing A-Series membranes, they are particularly well suited to processing liquids containing high levels of suspended solids, which makes them ideal for effluent treatment where the flux is found to be stable. The FPT10 has a nominal cut-off of 100 kD, is of smaller pore size compared with the FPT20, and its use can result in more stable fluxes.

Pipe penetration seals
Proco's Pen-Seals have been designed to assist in achieving a mechanical seal between pipes passing through walls, floors, tanks, pipeline casings, and vaults. The seals are designed to be gas and watertight. All sizes have been tested to withstand a hydrostatic seal up to 20 psig or 40 feet of head pressure in addition to withstanding temperatures up to 250°F. The standard elastomer is EPDM, which is suitable for most water applications—above ground and direct burial. The seals use glass-reinforced plastic for the pressure plates and all hardware is manufactured from steel zinc dichromate.
The Ashcroft® multi-instrument assembly allows a pressure gauge, switch and transducer or any combination of two, on one iso-ring and flanged unit. In flow-thru applications when it is necessary that pressure instruments be isolated from the process, an iso-ring is used. Often, more than one type of pressure instrument is needed, requiring several iso-ring/instrument assemblies. Now, only one iso-ring and flange assembly is required for up to three Ashcroft pressure instruments, with no effect on accuracy. A built-in needle valve dampens pulsation and allows the process to be locked off for safe removal of the instruments for recalibration. Assemblies are available for pipes from 1 in. to 20 in.
The Eclipse #2 Post Hydrant is ideal for wash-down or any other plant application requiring 2+ inches of water supply. The hydrants are manufactured with all brass working parts and cast iron exterior. They are self-draining for freeze protection and are easy to service. Options include hand-wheels and flanges for installing the hydrants in floors or decks. AutoCad installation drawings are available on the company's website.

The Hydroxyl Fluidized Fixed-Film Return Activated Sludge (F3RAS) treatment approach provides a solution to biological wastewater treatment upgrades. Building upon widely accepted activated sludge technology, the process incorporates a proprietary Free Floating Carrier (Hydroxyl-PAC media) in existing activated sludge basins. The media provides a large area for attached growth biofilm to supplement the suspended growth biomass in an activated sludge basin. The substantial biofilm growth provided by the media facilitates increased capacity (including nitrogen removal) of existing activated sludge plants without increasing any solids load on the final clarifiers and with minimal or no modifications to the existing plant.
Ondeo Nalco's High Performance Polymers are proprietary, high molecular weight liquids specifically designed for biosolids thickening and dewatering, and wastewater clarification.

New self-cleaning filters from Reclaim Filters and Systems provides a solution for high flow rates without having to change filter bags. Incorporating a stainless steel filter housing from Micron Technologies, the systems incorporate a stainless steel frame and filter housing to eliminate the problems of corrosion and rust through. The self-cleaning filter uses a permanent stainless steel filter element that is automatically backwashed using compressed air to blow out the dirt and debris from the filter element. Preprogrammed cleaning keeps the filter permeable and prevents clogging. Use of optional ballast or twin alternating filter can achieve uninterrupted flow.
