Here is a possible solution outline:

For this industrial wastewater, a combination of HPD membrane systems with pre and post-treatment steps would be effective. A possible solution might involve:

• **Pre-treatment:** * **Screening and Grit Removal:** To remove large debris and grit that could damage the membranes. * **Coagulation and Flocculation:** To remove suspended solids and reduce the organic load. * **pH adjustment:** To optimize the membrane performance and minimize fouling.
• **HPD Membrane System:** * **Nanofiltration (NF) or Reverse Osmosis (RO):** To remove organic pollutants, heavy metals, and remaining suspended solids. The specific choice between NF and RO would depend on the specific contaminants and desired purity level.
• **Post-treatment:** * **Disinfection:** To kill any remaining bacteria or viruses. * **Polishing:** To further improve water quality for potential reuse applications.

This HPD-based system would help the facility meet its environmental goals by:

• **Reducing water consumption:** Treated wastewater could be reused for non-potable purposes, lowering water demand.
• **Minimizing wastewater discharge:** The treatment system significantly reduces the pollution load discharged to the environment.
• **Improving environmental compliance:** The system ensures that the wastewater meets regulatory discharge standards for heavy metals and other contaminants.
