The application object is relatively single, mainly consisting of municipal sludge, some livestock, and poultry manure. The research of greenhouse composting system focuses on the different solar heating method such as single solar greenhouse, solar-heated water, and solar-heated air.
Jan 1, 2023 · The substrates used in the anaerobic co-digestion were sewage sludge, wine vinasse and poultry manure in ratio (S:V:PM) (49.5:49.5:1). This ratio was studied in previous work, where it was determined as the optimal mixture of these three substrates with the help of biochemical hydrogen and methane potential tests [34], [35]. The sewage sludge

Jan 1, 2017 · PDF | On Jan 1, 2017, K. Jeevanrao published Effect of Urban Compost, Sewage Sludge and Poultry Manure with Chemical Fertilizers on Yield, Nutrient Content and Uptake in Brinjal-Cauliflower
Composting is more than just piling the mate-rial and letting it sit, however. Composting is the active management of manure and bedding to aid the decomposition of organic materials by micro-organisms under controlled conditions. Efective composting is afected by four major factors: Aeration. Nutrient balance.
Jul 21, 2023 · Jain et al. designed a rotary drum composting machine, achieving ideal mixing effects in aerobic composting of waste such as water hyacinth, vegetable waste, sewage sludge, and industrial sludge. Yu et al. [ 27 ] and Li et al. [ 28 ] designed composting systems with automatic control systems to manage temperature, mixing, and ventilation.
Feb 15, 2022 · A completely randomized factorial design was used to evaluate: 1) dose: 100 and 600 kg N/ha and 2) type of amendment: poultry manure, compost, digestate, and fertilizer (urea).
Feb 18, 2016 · The main objectives of this study were to investigate the compostability of wastewater treatment sludge (WTS) containing different bulking agents (BAs) and to determine the most efficient BA. Four different compost trials consisting of mixtures of wheat straw (WS), plane leaf (PL), corncob (CC) and sunflower stalk (SS) with WTS were performed
E-479 06-08 Composting Manure and Sludge John M. Sweeten and Brent W. Auvermann* C omposting is a controlled, microbial process that converts biodegradable, organic materials into a stable, humus-like product.
