Pharmaceutical Wastewater Treatment EPC Project

We are pleased to announce that our EPC general contracting project for wastewater at a pharmaceutical company has successfully passed its final inspection! 🎉

Project Overview
The wastewater treatment plant adopts an advanced process: Coagulation Sedimentation + Hydrolytic Acidification + Anaerobic + Contact Oxidation. Designed capacity: 250m³/day, operating 20 hours/day, processing 13 tons/hour to meet discharge standards.

Wastewater Treatment Highlights

✅ Designed Inlet Water Quality:

• BOD ≤ 300 mg/L

• SS ≤ 300 mg/L

• CODCr ≤ 1800 mg/L

• Ammonia Nitrogen ≤ 28.2 mg/L

✅ Discharge Standards Achieved:

• CODCr ≤ 500 mg/L

• Ammonia Nitrogen ≤ 45 mg/L

• SS ≤ 400 mg/L

• pH 6.5-9.5

• Total Phosphorus ≤ 8 mg/L

• Total Nitrogen ≤ 70 mg/L

Process Flow
1️⃣  Production wastewater is collected and pumped into the coagulation sedimentation tank, where PAC, PAM are added to remove phosphates.
2️⃣  The wastewater flows into a biological treatment system (anaerobic + aerobic + coagulation sedimentation).
3️⃣  Treated water is safely discharged, while sludge is directed to a sludge tank for further processing.

With this project now in operation, wastewater treatment efficiency and quality have significantly improved. We remain committed to high-quality, efficient, and rapid after-sales service to safeguard our clients' interests.
