Treatment of Paper and Pulp Wastewater Using Coagulation-Flocculation with Alum: Optimization and Performance Evaluation
Industrial wastewater poses significant environmental and health risks due to its diverse pollutant composition. This study investigates the effectiveness of coagulation-flocculation treatment using aluminum sulfate (alum) for treating paper and pulp wastewater. The results highlight the significance of pre-biological treatment, pH optimization, alum dosages, and pre-filtration in enhancing removal efficiency for total solids (TS), total dissolved solids (TDS), total organic carbon (TOC), and ion concentrations. Pre-filtration significantly improved treatment performance, resulting in a 67% reduction in TS. Ion chromatography provided insights into post-treatment ion concentration changes. Under optimal conditions, including a treatment with 500 ppm alum dosage, alkaline pH of 11, and pre-filtration, the highest TS and TOC removal efficiencies were (52%) and (77%), while TDS reduction reached a maximum of 40% at lower alum dosages (100 mg/L). This study contributes crucial insights into optimizing alum coagulation-flocculation for paper and pulp wastewater treatment, offering potential solutions to mitigate industrial pollution and secure water resources.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
