Apr 4, 2024 · The characterization of compost compositions on the basis of sewage sludge and structural materials (straw, sawdust, bark) composting is described. A comparison of the most often used for composting and characterization of structural materials is also presented. Sewage sludge and structural materials were mixed in different ratios and composted in piles (laboratory scale) for 3 months
Nitrogen (N) fertilizer is highly significant in agricultural production, but long-term N addition causes changes in quality indicators, such as soil organic matter (SOM), thus affecting the absorption and accumulation of organic pollutants. Therefore, paying more attention to organic fertilizers in
Aug 8, 2023 · Two years of research were carried out to evaluate the effects of various sewage sludge and nitrogen doses on the turf performance of perennial ryegrass (Lolium perenne L.) under Mediterranean-type climatic conditions. Four nitrogen sources (NS) [NS1: ammonium nitrate (26%), NS2: Bursa City’s wastewater treatment plant’s waste, NS3: biogas production plant reactor waste, and NS4: food
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.
4. Using treated municipal wastewater effluents and sludge on agricultural land provides an production of crops. Sewage sludge and wastewater effluents can provide essential plant nutri-ents the physical condition of the soil and render it a more favorable environment to manage the nutrients and water. However, unlike manufactured fertilizers
Jun 24, 2022 · Moreover, four bio-enhanced degradation scenarios of FQs were set up according to the different temperatures and carbon–nitrogen ratio (C/N) in the sewage sludge composting stage, and the molecular dynamic (MD) simulation assisted by protein–protein docking was used to screen the external environmental factors that promote the degradation
Oct 27, 2015 · Sewag e sludge (SS), or bi osolid, is a by-product of wa stewater treatm ent plants that re-. mains after muni cipal wastewat er treatment (Kalde ris. et al. 2010). Considering that SS contains

The movable covers enable temperatures to be monitored throughout the process, which, during the first stage, rise above the critical point of 55 degrees—the temperature necessary for the organic
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
Apr 1, 2023 · One of the most pressing environmental problems worldwide is sewage sludge (SS) management. Every year, wastewater volume increases and thus, the amount of SS produced increases as well. The disposal of SS in landfills, as practiced in many countries, is not a sustainable solution. Instead, SS, rich in organic matter and other nutrients, can be used as an alternative soil additive or

Sludge Composting. According to statistics there are nearly 600 sewage treatment plants in China at present. And the sludge generated during the sewage treatment process is about 0.3-0.5% of the sewage treatment capacity. If we calculate based on this data, China’s municipal sewage treatment plants discharge is about 1.4 x 10t/a of dry sludge.
In 2022, Iguá's operation in Cuiabá (Águas Cuiabá) launched a project to transform sewage sludge into agricultural fertilizer, in partnership with local research centers and in alignment with the granting authority. Sewage sludge goes through a series of physical-chemical and biological treatments to prepare it for use in soil.
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and
