It reduces proton leakage in acid concentration and acid recovery applications, thereby improving acid recovery rate and current efficiency. It is commonly used in diffusion dialysis and acid concentration electrodialysis systems.<\/p>\n<h2>Structure and Principle<\/h2>\n<ul>\n<li>Introduce a barrier layer or adjust the crosslinked structure in the anion-exchange membrane matrix to suppress co-migration of hydrogen ions.<\/li>\n<li>Anions can still pass through normally, while reverse migration of protons is restricted.<\/li>\n<li>With reduced proton leakage, the acid concentration in the acid chamber is maintained, and the recovery rate increases accordingly.<\/li>\n<\/ul>\n<h2>Product Features<\/h2>\n<ul>\n<li>Effectively reduces proton leakage during acid recovery and improves acid recovery rate.<\/li>\n<li>Helps improve current efficiency and reduce power consumption per unit treatment capacity.<\/li>\n<li>Good acid resistance and suitable for inorganic acid systems such as hydrochloric acid, sulfuric acid, and nitric acid.<\/li>\n<li>When used with diffusion dialysis membranes and bipolar membranes, it optimizes the overall efficiency of acid and alkali recovery processes.<\/li>\n<\/ul>\n<h2>Application Industries<\/h2>\n<ul>\n<li>Improved efficiency of waste acid recovery and acid concentration systems.<\/li>\n<li>Waste sulfuric acid and waste hydrochloric acid recovery in steel pickling, titanium dioxide, and electroplating industries.<\/li>\n<li>Online acid regeneration and acid recycling on pickling lines.<\/li>\n<li>Recovery and purification of acid catalyst solutions in fine chemicals.<\/li>\n<\/ul>\n<h2>Specifications and Models<\/h2>\n<div class=\"iw-table-wrap\">\n<table class=\"iw-table\">\n<tr>\n<th>Parameter<\/th>\n<th>Unit<\/th>\n<th>Typical value<\/th>\n<\/tr>\n<tr>\n<td>Membrane Type<\/td>\n<td>\u2014<\/td>\n<td>proton-blocking anion-exchange membrane<\/td>\n<\/tr>\n<tr>\n<td>proton leakage inhibition rate<\/td>\n<td>%<\/td>\n<td>Actual operating conditions apply (typical values vary by system)<\/td>\n<\/tr>\n<tr>\n<td>Area Resistance<\/td>\n<td>\u03a9\u00b7cm\u00b2<\/td>\n<td>2\u201310 (typical value)<\/td>\n<\/tr>\n<tr>\n<td>acid recovery rate improvement<\/td>\n<td>%<\/td>\n<td>Actual operating conditions apply (typical values vary by system)<\/td>\n<\/tr>\n<tr>\n<td>Operating temperature<\/td>\n<td>\u2103<\/td>\n<td>5\u201345 (typical)<\/td>\n<\/tr>\n<tr>\n<td>applicable acid types<\/td>\n<td>\u2014<\/td>\n<td>sulfuric acid \/ hydrochloric acid \/ nitric acid and other inorganic acids<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<p>The data in the table are common ranges for similar equipment and are for selection reference only;
