Alexandria Textile Mill — Wastewater Treatment
Chemical treatment system achieved 95% color removal and compliance with discharge limits.
Challenge
A textile dyeing facility in Alexandria was discharging highly colored wastewater that exceeded regulatory limits for color, COD, and suspended solids. The facility faced fines and potential shutdown.
Solution
CHIMI ART designed a two-stage treatment: ferric chloride coagulation for color and COD removal, followed by anionic polyacrylamide flocculation for solids separation. Dosing was automated based on flow rate.
Results
- 95% color removal across all dye types
- COD reduced from 1,200 mg/L to below 250 mg/L discharge limit
- Full compliance with Egyptian environmental regulations achieved in 6 weeks
