The Hadwaco system for treatment of industrial and municipal waste water, leachate from landfills and for preparing drinking and process water has in a relatively short time become an attractive alternative to conventional evaporation solutions.  Based on mechanical vapour recompression (MVR) and the falling film principle, the system is reported to have several benefits when compared with competing technologies. The advantages include, for example, good purification results, lower energy consumption and lower investments costs. 

Turbo blowers offer greater economic benefits when compared with compressors and other competing equipment in producing the large amounts of compressed air that are needed in aeration basins at waste water treatment plants.  According to ABB Fläkt Oy in Finland, benefits include lower investment and running costs, reliable and trouble-free operation, and a short delivery time. Four blowers from the company's turbo blower range for aeration, known as Exvel Bio, are now in operation at the Glenelg waste-water treatment plant in Adelaide, Australia.

A new metro car – Vagn 2000 – is now being launched on the international market.The ride is very comfortable and the noise level is low, according to manufacturer Adtranz Sweden.Passengers are informed about the current station via electronic signs and loudspeakers.

The new TEX 05P from Atlas Copco Construction Tools is a lightweightdesign that builds on the company's established range of versatile chipping hammers.

A new range of radar level gauges based on advanced radar technology (FMCW) is about to be launched. There are three versions designed to be used in both simple and complex measuring applications. The radar level gauges claimed to be very reliable even under severe conditions, such as turbulence, or high temperatures and pressures. As a result, their sensitivity is much greater than that of earlier systems, according to Saab Tank Control AB, the Swedish company that developed the instrument.

A new network mirroring software solution, said by its manufacturer to provide the first continuous data protection for Sun Solaris systems, has been introduced by Qualix Group, Inc. The product, Qualix DataStar, reduces potential data loss, allows data recovery in minutes and speeds the resumption of business operations in the event of a system failure or disaster.

Computerised processing helps firms speed up visitor logging and internal changes to the access control system. At the IFSEC Fair, Bewator, a major supplier of access control solutions, launched Bewapass/Entro, a PC-based access control system, developed for ease of installation and use.

A new pacemaker, Polarity, offers a solution to an old dilemma. Using a new method to sense spontaneous heart activity, the more flexible and long-lived type of unipolar lead can now be used in the atrium as well. ”This is an important step forward, especially for children who need a pacemaker,” says the manufacturer, Pacesetter.

The large German shipyard in Wismar is the first in the world to build supertankers under cover. The ships are built in an indoor dry dock with an accordion-type door claimed to be the biggest in the world.The door is 64 metres high, 72 metres wide, weighs 280 tonnes and can handle wind forces up to 150 km/h. Several leading door manufacturers competed to win the prestige order.
