Membrane treatment

Pennwell web 175 300

The new T-Rack® Vario from inge watertechnologies is an ultra-compact rack system which features feed and drain pipes integrated in the end caps of the modules. The filtrate connections are welded to the module bodies and headers and there are no O-rings. All the flanges of the header pipes are mounted in the same plane. The modules can be arranged in either two or four rows and each row can be operated as a separate filtration line. This concept offers flexibility and helps keep investment and operating costs to a minimum.

Tank vents

Pennwell web 247 300

With environmental concerns having increased importance, the Shand & Jurs Expanda-Seal offers an unique advantage for weight/spring loaded conservation and emergency vents. The patented design allows pressure to build up on both sides of the seat ring, allowing the diaphragm to balloon around the seat ring. The company’s Expanda-Seal pallets are tested to 0.5 SCFH or less of air at 95% of the set point, which significantly reduces emissions and odors.

H2S monitoring

Pennwell web 300 258

The heart of the Jerome® H2S monitor from Arizona Instrument is the Gold Film Sensing Technology. A thin gold film, in the presence of hydrogen sulfide, undergoes an increase in electrical resistance proportional to the mass of hydrogen sulfide in the sample. When the sample button is pressed, an internal pump pulls ambient air over the gold film sensor for a precise period of time.
