Get contacts for EWC 10 01 06EWC 10 01 06 is a specific sub-code under EWC 19 09 — Wastes from the preparation of water intended for human consumption or water for industrial use. The classification guidance below applies to this waste stream.
EWC 19 09 covers wastes from the preparation of drinking water and industrial process water. Sub-entries: 19 09 01 (solid wastes from primary filtration and screenings), 19 09 02 (sludges from water clarification), 19 09 03 (sludges from decarbonation), 19 09 04 (spent activated carbon), 19 09 05 (saturated or spent ion exchange resins), 19 09 06 (solutions and sludges from regeneration of ion exchangers) and 19 09 99 (wastes not otherwise specified).
Water treatment sludges (19 09 02) from drinking water works are predominantly aluminium or iron hydroxide coagulant sludges from clarification of surface water. Composition reflects raw water quality — upland reservoirs produce low-metal sludges suitable for agricultural application or construction fill; groundwater treatment produces manganite and iron sludges. Heavy metal contamination of source water is reflected in sludge quality.
Spent ion exchange resins (19 09 05) from water softening and demineralisation contain concentrated calcium, magnesium, sodium, chloride and sulphate from regeneration. Resins from condensate polishing in power plants may concentrate radioactive isotopes (Cs-137, Sr-90) and require radiological assessment before disposal. Spent activated carbon (19 09 04) from granular activated carbon (GAC) filtration may be regenerated thermally at specialist facilities.
Typical Generators
Established valorisation pathways for EWC 10 01 06, ranked by economic value and market depth.
Dewatered aluminium hydroxide water treatment sludge (19 09 02) from clean surface water sources applied to agricultural land as soil conditioner and pH buffer. Must meet heavy metal limit values equivalent to sewage sludge standards under national provisions in absence of EU-specific regulation.
Spent granular activated carbon (19 09 04) thermally regenerated at temperatures 800–950°C in rotary kilns. Reactivated GAC returns to service; typically 5–10% mass loss per regeneration cycle. Regeneration reduces virgin activated carbon demand and disposal costs significantly.
Water treatment sludges not suitable for land application dewatered by belt press, centrifuge or filter press and disposed at non-hazardous landfill. Alum sludge from contaminated catchments may require hazardous landfill if heavy metal content exceeds WAC limits.
These are the established routes for EWC 10 01 06. Which one your stream qualifies for depends on its composition, volume and region.
