How much chloride is in composting leachate?

Chloride concentrations measured in composting leachates range from 32 to 8667 mg/L (Table 2). Thus, chloride in composting leachate can reach concentrations ten times higher than the criterion. Concentration of total suspended solids (TSS) in composting leachates is also highly variable (86–33 680 mg/L).

Can tops be treated during composting leachate treatment?

However, no subsequent studies conducted on the treatment of composting leachates have assessed the presence of TOPs or the capacity of the different technologies to treat these contaminants. Thus, in the future, the fate of TOPs during the leachate treatment should be considered. 2.

What is composting leachate contamination?

Composting leachate contamination mainly occurs during the percolation of water (liquid phase) through the composting of organic waste. Organic wastes are a major source of biodegradable organic matter, heavy metals, as well as emerging contaminants such as plasticizers (Fig. 2).

Can coagulation-flocculation be used for composting leachate treatment?

The use of coagulation-flocculation as a standalone process for composting leachate treatment has been well discussed in terms of removal efficiencies for COD, TSS and heavy metals. However, studies are lacking information regarding some important contaminants such as ammoniacal nitrogen and phosphorus.

How does composting technology affect Leachate composition?

The composting technology affects the leachate composition in two different ways: (1) by controlling the water supply in the process, and (2) by influencing the oxic conditions in the composted waste.

Can composting leachates be reused?

While the compost itself can be reused as a beneficial soil amendment, composting leachates contain various hazardous substances that can have potential adverse effect on the environment, and that therefore need to be sufficiently treated prior to disposal (He et al. 2015; Mokhtarani et al. 2015).
