Jan 18, 2023 · Dewatered sludges from twenty-two sewage treatment facilities were characterized to develop the quality control indices in India. This study used fertilizer index (FI) and clean index (CI) as a tool for categorizing sludge utilization into different classes (A, B, C and limited use classes LU-1, LU-2, LU-3) by their fertilizing potential, toxicity level, pathogen presence, and vector
In addition to the organics in MSW, some commercial and industrial sources of organic waste also make excellent feedstock for compost production. Examples of such feedstock include: fish processing waste, bark and sawmill waste, biosolids such as animal manure, leaf and yard waste, and untreated paper and wood waste. Biosolids from sewage sludge

Oct 27, 2015 · In order to use sewage sludge (SS) composts in agriculture, it is extremely important to estimate the quality of compost products. The aim of this study was to investigate the quality of composted SS as a fertilizer and soil amendment especially in semi-arid areas.
Oxygen is an important parameter for organic-waste composting, and continuous control of the oxygen in a composting pile may be beneficial. The oxygen consumption rate can be used to measure the degree of biological oxidation and decomposition of organic matter. However, without having a real-time online device to monitor oxygen levels in the composting pile, the adjustment and optimization of
Jan 12, 2024 · 2 Sewage sludge generated in w astewater treatment plants should be differ entiated from fecal sludge accumulating in on-site sanitation systems like septic tanks ( septage ) or pit latrines.
Aug 17, 2021 · In this study, the operations of six industrial composting facilities that process municipal solid waste and sewage sludge were evaluated from the point of view of the sanitation achieved and the quality of the compost produced. In addition, the results were compared using the model of industrial compost from green waste.
Jan 2, 2024 · Sewage sludge in natura is rich in nutrients, water, and organic matter and is essential for plant development. However, sewage sludge is diluted with water when composted, which could hamper plant growth. Therefore, supplementation with chemical fertilization may be necessary. This study evaluated the performance of composted sewage sludge (CSS) in producing Peltophorum dubium (Spreng.) Taub
