Sep 20, 2022 · Composting is one of the ways to return sewage sludge nutrients to the soil and thus keep them in the economic cycle. This well-known technique is still being developed in search of more advanced, optimal solutions. This study presents the results of an environmental and economic analysis of the sludge treatment processes used in a municipal wastewater treatment plant. The sludge (up to 4700
Jul 24, 2020 · The objective of the study was to characterise co-composting dynamics and maturity of the end products of sewage sludge/ green waste mixtures. We analysed all initial substrates and co-composts, sampled at different composting times for studying (1) physicochemical parameters and (2) organic matter biodegradation and biotransformation using pyrolysis coupled to gas chromatography and mass
Dec 22, 2020 · Conventional fertilization practices in agroecosystems concern the supply of bioavailable nutrients, such as mineral fertilizers. A consolidated alternative to restoring the long-term fertility of agricultural soils is their amendment with organic fertilizers. Soil amendment with biowaste compost or sewage sludge represents a sustainable strategy to avoid the landfilling of organic matter
Oct 15, 2023 · The objective of this study was to enrich the nutrient content of compost and to investigate the passivation and solubilization of plant micronutrients (Fe, Al, Cu, Ni, Zn, Na, Mn), macroelements (P, K, Mg, Ca), and heavy metals (Cr, Cd, Pb) during sewage sludge composting with nutrient-rich biomass ash additives. T0: 0%, T1: 3.5%, T2: 7.0%
Oct 1, 2008 · Abstract. To analyze metabolically active thermophilic bacteria, a high-temperature direct viable count (HT-DVC) method was developed and applied to sewage sludge compost made by a hyperthermal
Jan 14, 2013 · While the EPA has given the use of sewage sludge its blessing some of its own scientists disagree that it’s safe. And for good reason. When you spread sludge on farmland or use a bag of compost you bought at a nursery or home-and-garden supply that’s made with sludge, you’re also spreading contaminants.
Apr 1, 2023 · The changes in temperature values between compost piles are the result of increased microbial activity due to the balancing of low carbon and high moisture contents by the increase in the amount of rice husk added to the sewage sludge. The temperature in the compost pile containing only sewage sludge was in the fifth, and the temperature of the
Oct 1, 2023 · Pteris vittata L. (PV), an arsenic (As) hyperaccumulator, has a potential to extract As from As-polluted soils. Since available As in soils can be taken up by PV, As fraction variation associated rhizosphere environmental characteristics caused by municipal sewage sludge compost (MSSC) could provide possible to strengthen As phytoextraction by PV.
Those results suggested that HM bioavailability in high-N addition soil was lower than that in low-N addition soil when applied with SSC. Overall, this study found that increasing soil N content can inhibit the bioavailability of HMs when applying SSC, providing suggestions for optimizing the trialability and risk assessment of SSC application.
N2 - To analyze metabolically active thermophilic bacteria, a high-temperature direct viable count (HT-DVC) method was developed and applied to sewage sludge compost made by a hyperthermal composting method.
Nov 1, 2020 · As illustrated in Fig. 6 B, sludge compost was one of the most widely used technical routes for sludge treatment in China, exhibiting explosive growth during the past 10 years. Treatment capacity of the sludge compost plants built in China in 2009 was approximately 300 t/d ( W c , 80%), and it dramatically increased to 8140 t/d in 2015 and
Nov 5, 2020 · In the city of Sharjah, UAE, sewage sludge (SS), green waste (GW), and food waste (FW) are the most commonly produced organic wastes. For proper waste management in Sharjah, it is important to have a form of composting process using all of these types of wastes. Currently, the compost plant uses SS and GW for co-composting practice.
