Behavior of Sludge Dewaterability and Nutrient Contents after Treatment with Cellulose-Based Flocculants with Combined PTS and Catalytic Behavior of Sludge towards Tetracycline Degradation

Wastewater treatment plants are increasingly interested in adopting inorganic coagulants and organic flocculants their sludge process since disposal costs more than half of the overall operational costs. This study synthesized poly titanium sulfate (PTS) by different molar ratios used best one with cellulose-based for conditioning. PTS a 1:2 ratio showed lowest capillary suction time (CST) was selected further studies flocculants. As bio-based have gained popularity due to current environmental problems, cationized (Ce-CTA) were this work or without treatment. After coagulation–flocculation, dewaterability enhanced, Lowry Anthrone method assess proteins polysaccharides. Next, metal content nutrients such as total phosphorus, phosphate, nitrate measured ICP-OES IC, we found promising results phosphate especially at pH 3. Higher phosphorus 3 9, even 6 after PTS+Ce-CTA In addition, PTS-treated materials also catalytic behavior, suggesting new research avenue future development. Based on study, combination is nutrient recovery, along possibility valorization materials.
