Chemical Tank Cleaning Eliminates Town's Chlorine Demand   Water & Wastes Digest May 2003   Ulrich Reimann-Philipp, Ph.D.
Finished water quality often declines in storage facilities. Traditional tank cleaning methods have some effect in removing loose debris and sediment, but leave most of the scale, metal oxide deposits and biological growth in place. Chemical cleaning methods have been widely applied in Europe for years and have become an essential part of preserving water quality in systems which operate with minimal or no chlorine.

Aeration for Ponds and Cisterns   Water Quality Products January 2003   Jeff Roseman, Aqua Ion Plus+ Technologies
Using oxygen for the natural cleansing of water is becoming a viable alternative for pond and cistern owners in reducing the use of chemicals to fight the bacteria and algae that can become a nuisance. An aerobic bacterium needs oxygen in order to maintain the balance of nature. This article will take a look at some methods for increasing oxygen content, Henry's Law and applications that benefit from increased levels of O2.

Portable Tanks Help In Gas Pipeline Expansion Project   Water & Wastes Digest May 2002
By reclassifying the existing pipeline, PG&E avoided the enormous expense of laying 38 miles of new pipe. The primary objectives of the project were to safely raise natural gas pipeline pressure without increasing the release of nitrogen oxide (NOx) into the atmosphere. These objectives were achieved by relocating two pressure limiting stations, retrofitting two internal combustion compressors, and performing pipeline hydrotesting operations.

Tanks Pull Double Duty   Water Engineering & Management February 2002   Dan Zienty
Following the adoption of the Telecommunications Act of 1996, water storage facilities have become fair game for the installation of antennas and associated ground equipment. A storage tank pulling double duty raises maintenance and safety issues for consideration by municipalities and their system operators.

Minimizing Out-of-Service Time During Tank Painting   Water Engineering & Management February 2002
Tank painting projects can cost many thousands of dollars, but often the most costly aspect of tank rehabilitation is having your tank out of service. What can be done to get your tank back in service sooner? One approach is to control the environment and minimize delays due to poor weather. Another is to use coatings that tolerate a wide range of climatic conditions and cure quickly at ambient temperature. By combining these methods, down-time can be greatly reduced.
