Jan 1, 2023 · Aerobic composting was found to be an effective way to degrade triclosan in sewage sludge, as it effectively degraded and inactivated triclosan during the thermophilic phase, thus ensuring the stability and safety of the composting products.
Nevertheless, sewage sludge, especially if it comes from domestic or industrial waste, contains pathogens, heavy metals, and organic toxic pollutants that limit its land applica‐ tion [28,29].
Therefore, industrial composting of sewage sludge results in a bio-safe final product suitable for use in a variety of applications. Introduction. The accelerated appearance of antibiotic resistance has become a global health problem ( Abadi et al., 2019; Mobarki et al., 2019 ).
Nov 16, 2016 · Compost with nutrient-rich organic matter can be produced from renewable biomass materials such as municipal sewage sludge, landscaping waste and others. In this study, co-composting of municipal sewage sludge and landscaping waste as a soil amendment using 10 m3 pilot scale bioreactor system was tested. The temperature, oxygen level, moisture content and pH were monitored throughout the
Sep 16, 2022 · The Kwik Composter is a one-of-a-kind large scale composting equipment that is not only completely silent in its operation but is almost 100% odourless. Where most other industrial composting or regular composting produces an offensive smell during the breakdown process, the result of the creation of noxious gases from putrefaction, our Kwik
Sep 10, 2021 · to evaluate the technical feasibility of co-composting of four types of organic wastes, namely olive mill pomace (OMP), sewage sludge from vegetable processing (SS), fresh residues from artichoke processing residues (AR), and wheat straw (WS). To this purpose, a composting plant equipped with a machine for turning and shredding the windrow was
Jan 14, 2021 · 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 experiments were performed for
Aug 1, 2023 · The purpose of the strategy is to enable safe and sustainable sludge use on land. We want to contribute to the Department for Environment, Food & Rural Affairs’ ( Defra ’s) and Ofwat ’s
Dec 24, 2021 · Therefore, industrial composting of sewage sludge results in a bio-safe final product suitable for use in a variety of applications. Keywords: antibiotic resistance; biosolids; clostridia; compost; enterobacteria; fecal contamination; fecal enterococci; metagenomics.
2.1 Objectives and scope. To compare the carbon emissions of two sludge composting technologies, this study took 1 ton of excess sludge (80% water content) from a wastewater treatment plant as the research object. The two sludge composting technologies investigated were aerobic composting and vermicomposting.
Jul 1, 2017 · 1. Introduction. Due to the high volume of sewage sludge currently generated worldwide (8.9 million tons of dry solid matter in 2010 according to Eurostat, 2015), as well as its high concentration in heavy metals (especially cadmium), organic micropollutants and pathogens, this waste must be properly managed to prevent environmental problems and risks for human health (Hendrickx et al., 2009).
Oct 19, 2023 · Sewage sludge treatment and disposal remains a challenging problem. Composting of sewage sludges is gaining increasing attention due to its cost-effectiveness, operation convenience, advantages in lifecycle management, and low greenhouse gas emissions. Disadvantages, such as long reaction time, significant land area occupation requirement, potential risks of residual heavy metals, and emerging
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
Dec 4, 2023 · One of the most widely used for sludge treatment. Sludge is held in the absence of air for 15 to 60 days at temperatures of 68 to 131°F. Anaerobic bacteria feed on the sludge, producing methane and carbon dioxide. In some treatment plants, the methane is collected and burned to maintain the treatment temperature.
