Calcium Nitrate Applications in Wastewater | USP Technologies
Practical curative dose rates for calcium nitrate vary anywhere from 1 to 2 gallons per pound H2S depending on the application. Nitrate Pricing and Sources. The most common form of nitrate on the market for hydrogen sulfide control is liquid calcium nitrate solution. Typical pricing for calcium nitrate solutions is $2.00 to $2.50 per gallon.
Dynamics of nitrite in wastewater treatment plants In Activated Sludge (AS) systems Nitrite (NO 2 ) develops as an intermediate product of nitrification and denitrification (1). Nitrite concentration in WWTP's is very low under normal conditions (around 0.1 mg/l).

What Are the Causes of High Nitrates & Nitrites in Wastewater?
The primary goal of municipal wastewater treatment is to remove soluble contaminants, notably nitrates and nitrites. Wastewater must first go through a series of pre-processing treatments to remove rags, tampons, condoms and grit. After these treatments, biological and chemical processes are used to remove nitrates and nitrites.
