Scientific information about ammonia, how to measure ammonia, why it's important, basic overview of ammonia, what affects it in water, and the acceptable ranges
Gives an explanation of the importance in purifying water to ensure that there is no more ammonia in it. This website also gives diagrams and pictures of an ammonia purification system.
This website tells you what ammonia is, how it's used, how people can be exposed to ammonia, ammonia's mechanism of action, immediate health effects of ammonia exposure, and ammonia exposure treated.
Ammonia in wastewater is present as ion where pH is neutral. Ammonia is separated as gas from wastewater by raising pH of water with alkaline addition. Separation is enhanced by increasing the operating temperature of the tower
-Ammonia may be present in drinking-water as a result of disinfection with chloramine. -The presence of ammonia at higher than geogenic levels is an important indicator of faecal pollution.
Granulated activated carbon filtration (GAC) effectively removes organic contaminants from water, but this filter system collects nitrate during the treatment process and then releases it into the water. Since nitrification occurs frequently with ammoniated waters, monitoring the amount of ammonia in GAC filters can control nitrate levels. This system reduces total ammonia in the system.
Environmental regulation, increased pressure on water resources and rising cost for wastewater discharges make wastewater treatment for recycling an essential investment for many industries. Ammonia is a major pollutant in many industrial and agricultural wastewaters, and its elimination is essential for wastewater to be reused or meeting local discharge standards.
