Wastewater Treatment (ETP Solutions)

At HNJ Hydro Chem, we design and deliver industrial wastewater treatment and Effluent Treatment Plant (ETP) solutions for clients in Pakistan and international markets. Our systems help you meet regulatory discharge limits, reduce environmental risk, and lower lifecycle costs through efficient treatment, reuse, and recycling. From influent study to commissioning and long-term support, we provide a complete, performance-focused solution built around your effluent.

What We Deliver

1) Engineered ETP Systems (End-to-End)

Every wastewater stream is unique. We start with effluent characterization and design a treatment train aligned to your compliance and reuse targets.

• Pre-treatment & hydraulics: screening, grit removal (where required), equalization, oil/grease separation (where applicable)

• Primary treatment: pH correction, coagulation–flocculation, clarification/settling for turbidity, TSS, and colloids

• Secondary (biological) treatment: reduction of BOD/COD using stable biological processes supported by aeration and process control

• Tertiary polishing: multimedia filtration, activated carbon adsorption, disinfection (as required)

• Sludge management support: handling philosophy, dewatering guidance, and disposal recommendations (as applicable)

2) Chemicals, Consumables & Process Optimization

We supply a complete range of ETP treatment chemicals and support their optimization, including:

• Coagulants & flocculants
• pH adjusters (acid/alkali)
• Disinfectants/biocides (where required)
• Bio-cultures for biological stability
• Specialty additives (antifoams, odor control, etc., where required)

3) Dosing, Automation & After-Sales Support

• Chemical dosing systems (selection, sizing, calibration, commissioning support)
• Monitoring & controls to stabilize operation and reduce manual variation
• Preventive maintenance, troubleshooting, and performance reviews
• Operator guidance to minimize chemical consumption and downtime

Reuse & Recycling Applications

Depending on influent and treatment level, treated water may be suitable for cooling tower make-up, gardening, and non-critical process applications (subject to required quality and site-specific standards).
