Siemens Water Technologies has launched the MemPulseT Membrane Bioreactor (MBR) System.

The system features a mechanical device that supplies irregular pulses of air to the MBR module, and has been designed to increase scouring effectiveness, and decrease operation and maintenance costs, and energy consumption. The system can be used in a wide range of municipal and industrial wastewater treatment applications. Siemens also says it can be retrofitted easily to existing plants wishing to replace conventional clarification processes with membrane separation.

ITT Corp has announced a strategic partnership with Mercy Corps, a global relief and development agency, as part of its corporate philanthropy program, ITT Watermark.The partnership includes a three-year, US$1 million commitment to help provide safe water during emergencies created by natural catastrophes such as floods, droughts and earthquakes.

When natural disaster strikes, access to safe and potable water is often the most critical need. Through this new partnership, ITT will support Mercy Corps' relief and recovery efforts, which include the provision of dewatering and water purification equipment. In addition, ITT will help Mercy Corps' on-the-ground staff with rebuilding and recovery of water and sanitation infrastructure long after a disaster.

Dow Water Solutions has announced two new FILMTECTM 8 inch salt water reverse osmosis (SWRO) membrane elements for desalination applications.

At 99.80%, Dow says the FILMTECTM SW30XHR-400i has the highest salt rejection consistently demonstrated in the industry, and can remove boron and other dissolved solids to help plant operators and municipalities meet increasingly stringent drinking water standards. With a guaranteed active area of 400 ft2 and flow rate of 6,000 gpd, the elements have been designed to enhance productivity and demonstrate high performance over operating lifetime. The automated fabrication allows for the use of shorter membrane leaves, which can reduce fouling and improve efficiency.

The total worldwide market for indoor air filters will rise almost 22% by 2012, to over US$7.7 billion, according to an online report by McIlvaine Company. The report, Air Filtration and Purification World Markets, predicts Asia will see the largest revenue growth, increasing 28.6% by 2012.

While Asia has the largest growth rate, the Americas has the largest market share of total world revenues for indoor air filters. The Americas holds 39.3% of the market in 2008, and although estimated to experience a slight loss of market share by 2012, this region will remain in first place with 38.3% of the total revenue. Asia is in second position, and will remain so until 2012.

Millipore Corp has opened a new membrane casting manufacturing facility in Carrigtwohill, County Cork, Ireland. The 30,000 ft2 facility almost doubles the company's membrane production capabilities in Ireland.

The new US$83 million membrane casting facility, which will employ more than 580 people, is expected to produce a majority of the company's membrane. As a core technology, these membranes are used in a wide range of Millipore products.

The gases generated by electrolysis and other electro membrane processes contain a mixture of hydrogen and oxygen. Technical installations require safe removal of this potentially explosive gas mixture. We take a look at an integrated equipment concept for degassing and the direct combustion of gases from electrolytical processes.

Introduction

FilterSense has launched the Model DP 20T (differential) and SP 20T (static) pressure transmitters. Both of which have a non-clogging design for mounting on the dirty side of a fabric filter baghouse or cartridge style dust collector. FilterSense says the transmitters are more reliable than tube style electronic and mechanical gauges.

Siemens Water Technologies’ Forty-X disc filter is now compliant with Title 22 of the State of California Water Recycling Criteria. As a result, the disc filter is an accepted filtration technology for projects that require Title 22 certification.

The Title 22 regulation requires filtration technologies to reliably meet specific performance parameters for wastewater reuse applications.

VWS Westgarth, a Veolia Water Solutions & Technologies company, has been awarded a US$20 million contract by SBM Inc to supply a complete water injection treatment package to the Petrobras P57 deep water oil development in the Jubarte field, Espirito Santo basin, offshore Brazil.

The VWS Westgarth package includes a membrane based Sulphate Removal Process (SRP). These membranes remove sulphate and other divalent ions from the sea water prior to injection, greatly reducing the tendency for barium sulphate and strontium sulphate scale to form in the reservoir and production system.

Lydall Inc has announced plans to close its manufacturing facility in St.Johnsbury, Vermont, USA and consolidate its North American automotive production into its Hamptonville, North Carolina, USA site. Approximately 190 employees will be affected by the closing of the St. Johnsbury operation, and more than 100 new jobs will be created at the Hamptonville facility.

Dale G. Barnhart, president and chief executive officer of Lydall, commented:"Due to the current downturn in the US automotive market, our two North American automotive plants are running at less than 50% capacity. Consequently, we looked at all possible options to rationalise our North American automotive production in the face of this increasingly difficult automotive market."

For filters to work successfully in the machine and processing environment, related equipment must also be managed correctly. This article takes an overview of steam traps, an integral part of steam heating and process plants.

Introduction
A steam trap is a device attached to the lower portion of a steam filled line or vessel which passes condensate,but does not allow the escape of steam. It is also a piece of equipment that automatically controls the condensate removal,air and carbon dioxide from a piping system with minimal steam loss. The hot condensate removal is necessary to prevent water hammer, which is capable of damaging or misaligning piping instruments.

Aqwise's AGAR® (Attached Growth Airlift Reactor) technology has been chosen for use at a new wastewater treatment plant, in the Golan Heights' southern region, situated near Kibbutz Meitzar, Israel.

The technology, has been designed for enhanced BOD and nutrients removal and will help the plant address the challenge of inflow peaks, associated with regional conditions, and allow gradual project scalability so as to adapt wastewater treatment capacities to the anticipated regional growth.

The Meitzar project is expected to be in operation by the beginning of 2009.
