1. Role and Effects ofPolyaluminum Chloride(th copy)PAC)

Action-

संगृहः PAC इत्यस्य विकल्पो पोलिमरासंगृहः। उपायः - ई colloids neutralize negative charges on suspended solids, colloids (np. oil, fine dust), and some heavy metal ions in the wastewater, causing them to destabilize and form micro-flocs.

4. कीलसम्बन्धाः

Jar Testing is Essential: Bench-scale tests are necessary to determine the optimal types, dosages, and ratios of PAC and PAM (typical range: PAC 50-200 mg/L, PAM 0.5-5 mg/L).

Sludge Management: The combined use can increase sludge volume, necessitating proper thickening and dewatering equipment.

अन्तिः

In steel plant wastewater treatment, PAC primarily provides "coagulation" for removing suspended and colloidal matter, while PAM enhances "flocculation" to speed up settling and improve sludge dewatering. Their synergy enables cost-effective and high-performance wastewater purification, making this combination a cornerstone for pretreatment and advanced treatment. Henan Secco Environmental Technology Co., Ltd. is committed to supplying reliable, high-performance PAM and PAC products, backed by technical expertise, to help steel plants achieve their water reuse and environmental compliance goals efficiently.
