Regeneration procedures and guidelines for softeners and two-bed deionizers
Effective methods for cleaning biologically fouled resin
The Boomsnub site in the state of Washington was listed as a Superfund site in 1995. The site consists of two parcels of land, which previously contained two unrelated businesses that contributed separately to contamination of soil and groundwater.
Superfund site cleanup of chromate-contaminated groundwater
Higher pH solutions, through the addition or use of alkalis such as sodium hydroxide, sodium bicarbonate or sodium carbonate, will result in severely decreased uranium regeneration
Measures to reduce uranium in the drinking water supply
Let's take a closer look at the technology and operation of ion exchange resins and processes used today in industrial water treatment systems.
Nitrates have no detectable color, taste or smell at the concentrations involved in drinking water supplies, and they do not cause discoloration of plumbing fixtures, so they remain undetectable to our senses. Nitrate removal processes must be either foolproof or include extensive monitoring of the treated water to detect breakthrough or determine the need for regeneration.
