Severe Wastewater Testing Programs for Rapid Evaluation of Coatings and Linings: An update

Severe Wastewater Testing Programs for Rapid Evaluation of Coatings and Linings: An update
Available for download

High performance protective coatings are often failing in the severe headspace environments of wastewater environments. These failures are attributed to many factors including glow permeability properties to resist H2S and other corrosive gasses present within these environments. Although the chemical and physical properties of coating systems can be determined in the lab, this is not the case for application variables and the effects of environmental factors.

High performance protective coatings are often failing in the severe headspace environments of wastewater environments. These failures are attributed to many factors including glow permeability properties to resist H2S and other corrosive gasses present within these environments. Although the chemical and physical properties of coating systems can be determined in the lab, this is not the case for application variables and the effects of environmental factors. Due to a dearth of testing practices for wastewater conditions, specifiers are faced with product selection based upon unsubstantiated claims by manufacturers for use in these severe environments. This paper discusses the advancement of a novel laboratory testing program designed to simulate the effects of a severe wastewater headspace environment and produces interpretable data in a period of 28 days.

On July 28, 1986 a tornado struck an area outside of Sioux City, IA, destroying one of the four power generation plants at Port Neal. The tornado registered an F4 on the Fujita scale, indicating that “devastating damage” had taken place on the ground. Although there were no major injuries to the employees at the plant, severe damage took place on the equipment.

On March 8, 1862 in Hampton Roads, Virginia the first iron clad vessel on the seas, the CSS Virginia (known to Northerners as the Merrimac), had its way with the navy of the Union. It was able to sail unmolested among the ships of the Union Navy and fire at will while taking hits itself with impunity. When dusk arrived the Virginia went to anchorage to wait for sunrise when it could inflict more damage.

This paper will offer general guidance regarding preservation by liquid applied coatings to the owners and operators of coastal and inland working vessels. The paper will discuss both new construction and maintenance painting and will offer suggested coating systems for the main areas of these vessels.
