Its crystalline aqueous compound is heptahydrate at room temperature, soluble in water, and almost insoluble in ethanol. Its aqueous solution oxidizes slowly in the air when it is cold and oxidizes quickly when it is hot. The coagulation effect is strong, the decolorization effect is good, and it can effectively remove sulfide phosphate and other substances.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Scope of application<\/strong><\/p>\n<ul>\n<li>It is used for flocculation purification of water, as well as for phosphate removal from municipal and industrial effluents.<\/li>\n<li>It is especially used for the decolorization treatment of bleaching and dyeing wastewater, and the effect is better.<\/li>\n<li>It is used as a precipitant to prevent eutrophication of water bodies. As a reducing agent, it can be used for the reduction of hexavalent chromium in electroplating plants.<\/li>\n<li>As a nutrient for microorganisms in the biochemical system, it enhances biological activity.<\/li>\n<li>As pigments, raw materials for the electronics industry, hydrogen sulfide deodorant, soil conditioner, etc.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong><b>Quality Standards<\/b><\/strong><\/p>\n<p>&nbsp;<\/p>\n<table>\n<tbody>\n<tr>\n<td rowspan=\"2\" width=\"180\">\n<p style=\"text-align: center;\"><strong><b>Item<\/b><\/strong><\/p>\n<p style=\"text-align: center;\">\n<\/td>\n<td colspan=\"2\" width=\"348\">\n<p style=\"text-align: center;\"><strong><b>I<\/b><\/strong><strong><b>ndex<\/b><\/strong><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td width=\"195\">Refined product<\/td>\n<td width=\"153\">Drying type<\/td>\n<\/tr>\n<tr>\n<td width=\"180\">Appearance<\/td>\n<td width=\"195\">Light green solid<\/td>\n<td width=\"153\">Light green solid<\/td>\n<\/tr>\n<tr>\n<td width=\"180\">Ferrous sulfate, %<\/td>\n<td width=\"195\">\u226585<\/td>\n<td width=\"153\">\u226598<\/td>\n<\/tr>\n<tr>\n<td width=\"180\">Titanium dioxide, %<\/td>\n<td width=\"195\">\u22641.0<\/td>\n<td width=\"153\">\u22640.05<\/td>\n<\/tr>\n<tr>\n<td width=\"180\">Insoluble matter, %<\/td>\n<td width=\"195\">\u22640.5<\/td>\n<td width=\"153\">\u22640.1<\/td>\n<\/tr>\n<tr>\n<td width=\"180\">Free acid, %<\/td>\n<td width=\"195\">\u22642.0<\/td>\n<td width=\"153\">\u22640.5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong><b>Usage<\/b><\/strong><\/p>\n<p>Generally, it is prepared into a 10%-25% aqueous solution and fully dissolved, and then added to the front section of the primary sedimentation tank of wastewater treatment or the back end of biochemical treatment, which can greatly increase the removal effect of phosphorus and COD.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Use in combination<\/strong><\/p>\n<p>Ferrous sulfate and Polyaluminum chloride\uff1aEnhance flocculation effect,Strong phosphorus removal effect.<\/p>\n<p>Click\uff1a\ud83d\udc49<span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/www.wingkeji.com\/zh\/product\/pac\/\">Polyalumium Chlorine &#8211; Shenzhen Wing Tech Co., Ltd<\/a><\/span><\/p>\n<p>Ferrous sulfate and aluminum sulfate \uff1aEnhanced flocculation effect,,improved removal of organic matter.<\/p>\n<p>Click\uff1a\ud83d\udc49<span style=\"color: #ff0000;\"><a style=\"color: #ff0000;\" href=\"https:\/\/www.wingkeji.com\/zh\/product\/aluminum-sulfate\/\">Aluminum Sulfate &#8211; Shenzhen Wing Tech Co., Ltd<\/a><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Packaging, storage and transportation<\/b><\/strong><\/p>\n<ul>\n<li>25kg bag,50kg bag,500kg bag,1000kg bag,1200kg bag, stored in a cool, ventilated warehouse.<\/li>\n<li>Keep away from fire and heat sources.
