pall’s sales and earnings surge

from Canadian company ZenonEnvironmental Inc.

California has been experiencinggrowing water shortages. The City ofRedlands is optimizing the use of itslimited drinking water supply byreusing wastewater for non-potablepurposes. According to DouglasHeadrick, chief of Water Resourcesfor the city, the efficient use of recy-cled water will free up around 7600million litres (about 2 billion gallons)of limited water resources, making itavailable for use as drinking water.The recycled water produced byZenon’s ZeeWeed MBR will be soldto industrial, commercial and agricul-tural customers.

“With the implementation ofmembrane technology, we now viewour treated wastewater as a valuableasset instead of a liability,” saidHeadrick. He says that making thechoice to use membranes was an easyone. The State of California has verystrict discharge requirements andZeeWeed membranes are certified tofully satisfy Title 22 regulations.

In addition, the local power-gener-ating plant, one of the utility’s largestrecycled water customers, has its ownstringent water requirements. Hesays that the use of the MBR by thecity will eliminate the need for therecycled water at the power plant toreceive further treatment before it isused it in the cooling towers, in thegeneration of electricity.

Koch unveils itsnew UF cartridgeKoch Membrane Systems (KMS)Inc of Wilmington, Massachusetts,USA, recently unveiled its 10-inch(25-cm) diameter ultrafiltration(UF) hollow fibre cartridge.

Evolving from the widelyinstalled KMS 8-inch (20-cm) car-tridge, this product contains 60%more membrane area and, claimsthe company, provides 60% moreproduct water per cartridge than itssmaller predecessor.

According to the company, thecartridge can reduce system floorspace requirements by up to 50%,depending on flow demand and

stage design. Furthermore, its useallows smaller systems to be designedand built that require fewer valvesand pumps. This, in turn, reducescapital equipment costs.

The cartridge is available in twohigh area, cost-saving sizes – a 48-inch (122-cm) long model, con-taining 51 m2 (or 550 ft2) of mem-brane area, and a 72-inch (183-cm)long model, containing a mem-brane area of 81 m2 (870 ft2).

These UF membranes have anominal 100 000 molecular weightcut-off for better than 4-logremoval of Cryptosporidium,Giardia and viruses. They canaccept a pH range of 1.5–13, andcan tolerate up to 200 ppm chlorineduring a cleaning cycle.

Hydranauticsawarded Florida-city contractUS-based membrane technologycompany Hydranautics has beenawarded a contract by the City ofBoca Raton, Florida, USA, to sup-ply a potable water plant, rated atover 150 million litres (about 40million gallons) per day.

This plant, which is believed tobe the largest in the USA, and per-haps the world, will use over 8000Hydranautics’ low-fouling ESNA1-LF nanofiltration membranes.

The plant will consist of 10 pri-mary softening trains, each capableof producing about 14 million litres(around 3 676 000 gallons) per dayof permeate water operating at 85%recovery. The system will alsoinclude two nanofiltration concen-trator units that operate as a thirdstage and produce 6 million litres or1 620 000 gallons per day, per train.These trains operate at a recovery of50% and add a total of 12 millionlitres (3 240 000 gallons per day) ofadditional treated permeate water.

According to Hydranautics, theESNA1-LF provides salt rejection of90% and controlled hardnessremoval, eliminating the need forhybrid membrane system designs. Italso claims that these low-pressuremembranes can significantly reduce

operating costs by lowering powerconsumption, while providing anon-aggressive low total dissolvedsolids permeate water. The mem-branes also use low fouling technolo-gy, which reduces the cost of chemi-cals and labour that are oftenassociated with cleaning membranes.
