A REVIEW OF FILTER PRESS BASICS AND ISSUES VERSUS ALTERNATIVE BATCH OR CONTINUOUS REPLACEMENT TECHNOLOGIES

INTRODUCTION

Filtration experts, over the years, have discussed and debated filter presses and have indicated that soon they would be a thing of the past; the last filter press would be replaced by more modern equipment. Given that filter presses were amongst the ... (read more)

Edwards, a leading global supplier of vacuum and abatement equipment and services, today introduced the Sirius™ 6000 abatement system. Designed for low cost-of-ownership, the Sirius 6000 system addresses greenhouse gas abatement challenges arising from dielectric and polysilicon etch processes used in semiconductor manufacturing.

Uni-Filters - FLSmidth Uni-Filters provide de-centralized dust collection from widely separated sources, reducing piping and power costs involved in large centralized systems. (read more)

HarmonicGuard drive-applied harmonic filters are used where drives are or will be installed, and harmonic reduction is necessary. Prime candidates for filtering are installations of variable frequency drives or adjustable speed devices in facilities where those drives represent a significant portion of the load, or when specifications call for limited harmonics (like IEEE 519, 1992).
