Praestol is often used where stable floc structure is important for continuous operation. This is typically seen in biological sludge where uniformity is critical to equipment performance.  <\/p><p>Zetag is often chosen when the load varies and there is a need for rapid flock formation and robust flocks that can withstand mechanical impact.<\/p><p>The choice between Praestol and Zetag depends on sludge type, dry matter, mechanical load and filtrate quality requirements. Therefore, the product should be evaluated together with dosage, solution and the equipment that will handle flocs in operation. <\/p><h3>Polymer selected according to sludge, filtrate and equipment<\/h3><p>Praestol and Zetag must be selected based on dry matter, particle structure, floc strength, filtrate quality, dosage and solution. At the same time, the polymer must be suitable for the equipment that handles sludge or process water in daily operation. <\/p><p>This makes it easier to achieve the correct dosage, keep the filtrate cleaner and make belt filters, decanters or disc filters work more uniformly.<\/p><h3>Polymer in wastewater and industrial processes<\/h3><p>Polymer applications are broad in both wastewater and industrial applications, including sedimentation, sludge dewatering and process water treatment, where challenges such as <a href=\"https:\/\/dankalk.dk\/en\/struvite-that-stops-functioning-and-creates-deposits\/\">struvite<\/a> , particles and varying solids can affect flow, filtrate and operation. <\/p><p>In plants with fluctuating loads, polymer becomes a crucial factor in maintaining capacity. The wrong polymer quickly results in poor separation, while the correct choice ensures that the equipment works as expected. <\/p><p>With the right Praestol or Zetag polymer, it becomes easier to handle changing loads, keep the filtrate cleaner and avoid unnecessarily high polymer consumption.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-5de2be1 e-con-full e-flex e-con e-child\" data-id=\"5de2be1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b70dd6d elementor-widget elementor-widget-text-editor\" data-id=\"b70dd6d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h3>FAQ &#8211; Frequently asked questions about praestol polymer and zetag<\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-351dcb0 elementor-widget elementor-widget-n-accordion\" data-id=\"351dcb0\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;n_accordion_animation_duration&quot;:{&quot;unit&quot;:&quot;ms&quot;,&quot;size&quot;:200,&quot;sizes&quot;:[]},&quot;default_state&quot;:&quot;all_collapsed&quot;,&quot;max_items_expended&quot;:&quot;one&quot;}\" data-widget_type=\"nested-accordion.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"e-n-accordion\" aria-label=\"Accordion.
