3. Hella Water Customized Solutions

3.1 Process Design: Integrated Electrocoagulation-Flotation-Sedimentation Technology

The solution adopts a “electrocoagulation → in-situ flotation → sludge separation” integrated process, realizing agent-free wastewater purification:

1. Electrocoagulation Stage:
   • Steel electrode plates generate metal hydroxides (coagulants) through electrolysis, which adsorb and aggregate suspended solids, colloids, and organic pollutants in wastewater.
   • Adjustable voltage (0-12V) and current (<1000A) adapt to different water quality conditions, ensuring stable treatment effects.
2. Flotation & Sedimentation Stage:
   • Bottom aeration device generates micro-bubbles, which adhere to flocculated pollutants and float to the water surface.
   • Top slag scraping system automatically removes floating sludge; bottom sludge collecting bucket and discharge system realize continuous sludge separation, avoiding equipment clogging.
3. Integrated Control:
   • Stainless steel electrical control box integrates rectifier and operation switches, simplifying parameter adjustment and equipment start-stop control.
   • Compact design (2500×1000×1500mm) integrates all functions, reducing installation space to ≤5 m².

6.4 Operational Cost

Q: What is the estimated daily operating cost of the equipment?

A: The main operating cost is electricity. The power consumption is ≤1.2 kW·h/m³, and the daily electricity cost for 12 m³/d treatment capacity is about USD 1.3 (based on 0.1USD/kW·h electricity price). There is no chemical agent cost, and the annual maintenance cost is about USD 200 (including electrode plate cleaning and spare part replacement), with a total daily operating cost of ≈USD 1.8.

6.5 Safety & Compliance

Q: Is there any safety risk during equipment operation (e.g., electric shock, gas emission)?

A: No. The equipment adopts low-voltage design (≤12V electrolysis voltage) and is equipped with a leakage protection device; the aeration system generates only oxygen and hydrogen micro-bubbles (diluted to safe concentration), with no toxic gas emission. It complies with national electrical safety and environmental protection standards.

Q: Can the treated water be directly reused for production or irrigation?

A: The treated water meets GB 8978-1996 Class A discharge standard; for industrial reuse (e.g., cooling water), it can be used directly after simple filtration. For agricultural irrigation, it needs to meet agricultural water purification requirements (GB5084-2005) through additional pH adjustment or disinfection.
