Look at the heating element of a washing machine or dishwasher in a hard water area and you will see a white encrustation containing hardness salts. This commonly is referred to as limescale and is an example of domestic fouling.
Industrial fouling poses a far greater problem than anything in the domestic sector. Huge volumes of fouled fluids are handled, and the systems that contain the fluids can become fouled as well. The quality of water streams used by industry varies widely and gives rise to numerous fouling problems.

Revisiting the Selection of Stainless Steel in Water and Wastewater Treatment Environments: Part 3

Based on the City of Hollywood’s experience, the use of 316L stainless steel should be evaluated carefully due to the potential for problems in the erection and construction of water treatment facilities that will be in contact with high chloride water and/or other corrosive chemistries. As with many membrane facilities, much of the stainless steel is exposed (not buried), which subjected it to atmospheric as well as water quality problems. Therefore, unless the quality control of the raw and reject water (chemical, physical and microbial) can be assured, 316L stainless steel may not be the appropriate material for engineers to specify.

Sulphur Water Solution

Goulds Pumps
For more than 220 years people have journeyed to White Sulphur Springs, W. Va., to indulge themselves in baths of mineral water flowing from mountain springs. As inviting as the sulphur water may be, it is equally harsh on the pipes and pumps that transport it. Eight years ago Greenbrier decided to stop the corrosion once and for all by installing an all-stainless model manufactured by Goulds Pumps.

Aerobic bacteria (Crenothrix, Gallionella) primarily are encountered in the fresh surface waters, although anaerobic sulfate-reducing bacteria and facultative strains also are encountered. Ground waters are more likely to contain anaerobic and facultative bacteria, as well as Gallionella than surface waters.3 Sulfate-reducing bacteria also are found in seawater.3

Hydrogen Sulfide Control in Wastewater Collection Systems
Water Engineering & Management

Tony Palmer, Paul Lagasse and Maureen Ross
When most environmental professionals think about hydrogen sulfide control in their wastewater collection systems, they are concerned with odor and corrosion. Instrumentation is now available to measure sulfides online, providing the opportunity to optimize the chemical dosage and monitor sulfide control.
