Wastewater sludge requires additional processing \u2013 thickening, digestion, dewatering, and once the volume is reduced, reclamation or incineration.<\/p>\n\n<p class=\"wp-block-paragraph\">Sludge dewatering is important because, for example, the dry solids concentration of primary or excess biological sludge averages 1\u20133%, after thickening before digestion \u2013 4\u20135%, after dewatering with centrifuges \u2013 20\u201330%, and after drying, more than 90%. As sludge dryness increases, the volume of dewatered sludge decreases accordingly. <\/p>\n\n<p class=\"wp-block-paragraph\">In almost all cases, chemical reagents \u2013 flocculants (polymers) \u2013 are used for wastewater sludge dewatering. These are special polyacrylamide mixtures in liquid or powder form, specifically adapted for dewatering different types of sludge:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>For dewatering primary sludge from industrial wastewater.<\/li>\n\n\n\n<li>For thickening and dewatering municipal wastewater sludge \u2013 primary, excess, and digested sludge.<\/li>\n\n\n\n<li>For dewatering mixtures of primary and biological sludge in industrial facilities.<\/li>\n\n\n\n<li>For managing sludge from ponds, lagoons, and lakes.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The selection of chemical reagents \u2013 flocculants, dose adjustment, and maintenance are important for various sludge dewatering processes, such as sludge thickening with belt and drum thickeners; sludge dewatering with belt, screw, and plate presses; sludge dewatering with centrifuges, sludge dewatering with dewatering bags, and other equipment.<\/p>\n\n<p class=\"wp-block-paragraph\">If your company also needs sludge dewatering services, UAB Ekotakas is ready to assist you. The company selects and supplies chemical reagents \u2013 flocculants designed for sludge binding and separation from water, determines optimal doses, adjusts and monitors all sludge dewatering processes. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Large quantities of a secondary product \u2013 sludge \u2013 are generated during the treatment of industrial and municipal wastewater.
