Mar 10, 2024 · Large-scale composting tests were conducted in two different locations (hereafter marked as A and B) in the Czech Republic. Composting mixtures composed of sewage sludge from municipal wastewater treatment plants, finely crushed tree barks, urban greenery waste, soil, and amounts of ash from power production plants or digestate from an agricultural biogas plant at varying proportions.

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. To determine the quality and agronomic value of the SS compost products, analyses on pH, electrical conductivity, organic matter

Jan 14, 2021 · 28 Citations. Metrics. In present study, the effects of carbon sources on compost process and quality were evaluated in the lab-scale sewage sludge (SS) composting. The composting

Sep 1, 2023 · Settled sludge from sludge treatment ponds has also been used to ‘mix’ compost from solid waste, as shown in Accra, Ghana; farmers in Ghana, Mali, and Benin have been known to bribe septic truck drivers to deposit fecal matter in their fields [50]. The most critical aspect is the SS quality, as it will influence the stabilization procedure

Oct 1, 2022 · According to the current study, metal ions and chloride ions remaining in the sludge after utilizing inorganic flocculants can cause corrosion issues in subsequent incineration equipment, and PAM-like polymers left in the sludge may also provide long-term environmental threats (Liu et al., 2020a). In recent years, numerous studies have adopted

May 1, 2021 · Abstract. Municipal sewage sludge is a significant by-product in the conventional treatment of municipal wastewater. Its output has greatly increased with the progress of urbanization and industrialization. The harmless disposal and resource utilization of municipal sewage sludge has become an urgent problem to be solved in the environment field.

Aug 30, 2023 · Complementary characteristics of rice straw (RS) and sewage sludge (SS) create a suitable mixture to be used in a composting process. This work studies industrial-scale RS and SS composting to assess both its viability and optimization. Windrow composting was conducted during two seasons.
