Nitrate has the molecular formula NOˉ3, therefore it consists of one nitrogen atom surrounded by three oxygen atoms, with a net charge of negative one.
It is a stable and highly soluble ion which makes it difficult to remove using conventional water treatment methods such as precipitation and adsorption. The IX process is the most suitable for water suppliers contaminated by nitrate. This is due to its simplicity, effectiveness and relatively low cost.
Lanlang ® TA465D is one of the most suitable product to solve your water problem. For it removal, the resin exchanges chloride ions for nitrate and sulfate ions in the water. After treating many gallons of water, the resin will "run out" of chloride. Regenerating the resin with a concentrated solution of sodium chloride (you can use bicarbonate instead of chloride) recharges it for further treatment.
Contact Lanlang, our engineer to develop a customized solution for nitrate removal. For more information, Lanlang offers Ion Exchange for Nitrate Removal resin data sheet specifically for potable and groundwater treatment.
Nitrates are naturally occurring. All rainfall and groundwater aquifers contain some nitrate-nitrogen. However, contaminated rural water supplies provide a clue for discovering other nitrate sources. It accumulates in agricultural watersheds where farmers spread inorganic fertilizers and animal manures on cropland. Nitrogen not taken up by crops can leach through the soil to groundwater and then flow to recharge areas or private wells. Residents in rural communities typically use on-lot septic systems and some homeowners rely on lawn fertilizers. These too can be sources of nitrate in drinking water.
