Development, current state and future trends of sludge

Nov 1, 2020 · Similarly, sludge composting has been used in 25 out of 27 countries in Europe, which accounted for as much as 42% of total sludge production in 1995 (3 million Mg of dry matter in suspend solids), and it quickly increased to 59% in 2010 (Collivignarelli et al., 2019), finally being used for agricultural utilization.

HUBER Solutions for Septic Sludge Treatment

After composting, the treated septic sludge is land applied as fertilizer and for soil improvement. We treat filtrate from sludge dewatering in a HUBER Membrane Bio-Reactor and recycle the effluent as process water (wash and spray water). Surplus effluent can be reused for irrigation.

sludge composting - principle and conditions governing its use

Composting is controlled fermentation that converts organic matter aerobically and produces stable humic and pre-humic compounds (figure 1). Aeration will only be effective if the medium is air-permeable. Dewatered sludge often has a low porosity; a bulking agent has to be added, usually in the form of a carbonaceous support (20% of the mixture

Phytoextraction of As by Pteris vittata L. assisted with

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.

Sewage sludge - European Commission - Environment
