EWC 16 10 covers aqueous liquid wastes destined for off-site treatment. This sub-chapter distinguishes 16 10 01* (aqueous liquid wastes containing dangerous substances) from 16 10 02 (non-dangerous aqueous liquid wastes), and 16 10 03* (aqueous concentrates containing dangerous substances) from 16 10 04 (non-dangerous aqueous concentrates).
This entry applies to process effluents, wash waters and liquid wastes that cannot be discharged via sewer or on-site treatment systems and require transport to an off-site treatment facility. Classification depends on contaminant identity and concentration against HP thresholds. Aqueous wastes are distinct from non-aqueous liquid wastes treated under chapters 7, 13 and 14.
Volume reduction strategies (evaporation, membrane filtration, reverse osmosis) may convert liquid waste to concentrated sludge, changing applicable EWC code. Generators must characterise all dissolved substances in the waste water matrix to enable hazard assessment. Mixing of different waste streams may create new hazardous properties (e.g. cyanide + acid generating HCN gas).
Typical Generators
Established valorisation pathways for EWC 06 01 99, ranked by economic value and market depth.
Contaminated aqueous wastes treated by neutralisation, coagulation/flocculation, precipitation and DAF. Resulting clarified water discharged to sewer or watercourse under permit; sludge dewatered for separate disposal.
Biodegradable organic-laden aqueous wastes treated in industrial wastewater treatment plants using activated sludge or biofilm processes. Pre-treatment to remove inhibitors required before biological stage.
Highly contaminated aqueous liquid wastes with organic content incinerated by liquid injection into rotary kiln or liquid injection incinerator. Energy content of organics offsets fuel costs; aqueous fraction increases steam demand.
These are the established routes for EWC 06 01 99. Which one your stream qualifies for depends on its composition, volume and region.
