Institute Offers Guide for Buying Precipitators

The Institute of Clean Air Companies, Inc., the national association of stationary source air pollution control and monitoring technology companies, released guidance on how to purchase and compare bids of wet electrostatic precipitator (WESP) equipment for electric power and industrial applications.

The guidance will improve the industry-accepted understanding of engineering principles and options for WESP designs and support technology considerations in the bid-purchase process.  

Although wet electrostatic precipitator technology has been applied since the early part of the 20th century, an increasing number of electric power and industrial applications are now requiring the installation of emissions control systems to address fine particulate and sulfuric acid mist emissions. This document was prepared by WESP manufacturers to help end users collect the necessary data to solicit bids from vendors, prepare bid documents, and evaluate bids received.  Explanations and commentary are included to aid the purchaser in writing complete specifications and properly define parameters needed for WESP design. The document furthers the contents of ICAC Bid Evaluation Form for Dry Electrostatic Precipitators, ICAC-EP-10, adopted in 1995, to focus on the requirements for wet electrostatic precipitator technology.
