D407 is a macroporous polystyrene-based Nitrate selective chelating resin. It selectively adsorbs Nitrate and Nitrite from water and /or waste water containing various other anions. The capacity is high and the resin can be regenerated easily. This resin is widely used for the treatments of drinking water, industrial waste water and city waste water to reduce the total Nitrogen.
Product Description
HAL LAN ™ D407 Chelate Resin Nitrate selective resin:With the eutrophication of environmental water, the content of nitrate and nitrite in water is increasing, which has threatened the safety of drinking water. In addition, perchlorate, as a highly destructive ion, has been strictly limited in drinking water in Europe and the United States (no more than 1mg/l).
With the development of mariculture, more and more people pay attention to the effect of seawater quality on the farmed organisms. Among them, timely removal of excess nitrate is an important link to control the quality of seawater.
Chelate Resin Nitrate selective resin D407 is a kind of quaternary ammonium anion-exchange resin with special structure. Nitrate and nitrite ions can be selectively adsorbed from fresh water (drinking water).

Regeneration Method:
D407 resin is usually used in single column. The exhausted resin is regenerated by passing 2-3BV of 5-8% NaCl through the resin in 1-1.5 hours. Then wash with DI water or clean water until conductivity of the effluent close to that of the influent. Then the resin is ready for next run.
Note: The regeneration waste of D 407 resin will be NaCl solution containing about 1g/L of Nitrate. It could be reused as regenerant after that the nitrate content is reduce to less then 100mg/L by denitrification process.
