SS316 Automatic Backwash Filter | New Zealand Electrocoagulation Wastewater Pilot Project

📍 New Zealand · 🌱 Wastewater Treatment Pilot · 📦 Automatic Backwash Filter
 
Pilot wastewater treatment projects demand high-precision, flexible and operationally stable filtration solutions to adapt to variable test water quality and phased experimental requirements. This case focuses on our customized SS316 Automatic Backwash Filter solution for a New Zealand electrocoagulation (EC) wastewater trial, covering demand analysis, technical optimization and final project delivery.

Project Background & Client Requirements

The New Zealand environmental protection client launched an electrocoagulation wastewater treatment pilot at a local community sewage treatment plant. To refine the effluent from the EC reaction tank and match the subsequent sludge dewatering press process, the client needed a professional automatic backwash filter for terminal water polishing and solid-liquid separation.
 

📌Core Technical Requirements

  • Application Scenario: Post-electrocoagulation wastewater advanced treatment
  • Core Function: Remove suspended sediments, flocculated inorganic solids and residual organic matter
  • Initial Filtration Precision: ≤25 micron (customizable upgrade required)
  • Design Treatment Flow: 1 m³/h (small-scale pilot system)
  • Influent Water Quality: TSS 20–50 mg/L after sedimentation tank, solid content about 3%
  • Material Standard: Full SS316 stainless steel corrosion-resistant construction

Technical Communication & Customized Solution Optimization

1. Baseline Solution Recommendation

Based on the client’s initial 25μm precision and 1m³/h flow demand, we firstly recommended the JX-XF-300 SS316 Automatic Backwash Filter as the standard matching solution, which fully met the basic filtration and stable operation requirements of the pilot project.

2. High-Precision Upgrade Feasibility Verification

During technical docking, the client put forward a higher demand for experimental testing: exploring whether the equipment could achieve 5 micron ultra-fine filtration to improve water polishing effect. After professional verification, we confirmed that the JX-XF-300 filter equipped with a 5-layer sintered mesh filter element can stably reach 5μm filtration accuracy, supporting the client’s high-precision test demand.

3. Operational Risk Optimization & Final Configuration Confirmation

Combined with the actual water quality characteristics (residual organic matter and polymer residues in wastewater), the client raised a key operational concern: a single 5μm fine filter element would easily cause rapid pressure rise, frequent backwashing and intermittent equipment operation, affecting the stability of long-term pilot tests. Therefore, the client hoped to adopt a dual-element alternative test scheme.
We provided one-on-one professional technical guidance for weeks, answering all questions regarding backwash water supply scheme, supporting pump selection and overall process flow design. After comprehensive evaluation, the client confirmed the final optimized configuration:
  • Equipment Model: JX-XF-400 SS316 Automatic Backwash Filter
  • Design Treatment Capacity: 800 L/h (adapted to pilot stable operation)
  • Customized Configuration: Equipped with 25μm + 5μm dual filter element sets for switching trial
 

Project Outcomes

The customized SS316 JX-XF-400 Automatic  Backwash Filter has been successfully delivered to the New Zealand site. The dual-element flexible configuration perfectly matches the client’s phased pilot test plan: the 25μm filter element ensures long-term stable daily operation and avoids frequent backwashing, while the reserved 5μm high-precision element supports subsequent advanced water treatment trials. The solution balances operational stability and experimental flexibility, fully meeting the differentiated needs of EC wastewater pilot projects.
