-At present, nitrate pollution is becoming more and more serious, which not only causes pollution to the environment, but also causes harm to the human body. Nitrate can be changed to toxic nitrite in the digestive tract. Then nitrite can oxidize low methemoglobin to high ferrous erythroprotein in human body. This compound can block oxygen transport and make people feel difficult to breathe. Excessive intake of nitrate can cause dullness, dizziness, and coma. Moreover,Long-term drinking water containing high concentrations of nitrate can poison humans and animals.
For that, many methods for removing nitrate have been developed, in which using ion exchange resin is more efficient and convenient. Suzhou Bojie Resin Technology Co., Ltd. provides several kinds of resins to remove nitrate from industrial wastewater, domestic sewage and drinking water.
-According to different technical sites, there are not only resins to remove nitrates. Common recommended methods include ion exchange, reverse osmosis, electrodialysis / reversal electrodialysis, biological denitrification and chemical denitrification.
If an ion exchanger is planned to be installed, there are several parameters to take into consideration, including the content of the water in suspended solids, the composition of the water including sulphates and bicarbonates. Also, if sodium chloride is used to regenerate the resins, it must be taken into account that there will be a significant increase in cl- ions.
-Yes,Tamie is right. if use ion exchange resin special for Nitrate and keep a high rate of removal , there will be several parameters to consider to design the ion exchange column, all the design is depending on the input water parameters and output standard. a whole solution delivery will be more thoughtful and easy to achieve, including the resin supply, scheme design, equipment installment, commissioning, training, and Turnkey, and even after-sale service and technology support.
