  • × Bleeding cash AGAIN by paying stringent wastewater discharge fees.
  • × Factory production is highly vulnerable to regional drought and water scarcity.
  • × Non-compliant with modern ESG and ISO 14001 corporate mandates.
WANDONG Water Reuse Solutions
  • ✓ Recover Up to 85%: Dramatically slash incoming water bills and discharge fees.
  • ✓ Drought-Proof Operations: Secure your own independent process water supply.
  • ✓ Superior Quality: Recovered RO water is often purer than local municipal tap water.
  • ✓ Rapid ROI: Most systems pay for themselves within 1.5 to 3 years.

> INITIATING SYSTEM OVERVIEW: WANDONG ENVIRO represents the pinnacle of skid-mounted industrial water reuse integration. By treating secondary biological effluent with advanced dual-membrane (UF+RO) technology, our plug and play reuse skids recover up to 85% of plant wastewater, transforming it into highly profitable process water.
> PROCESS ANALYSIS: The heavy-duty reuse process architectures are built exclusively utilizing Tier-1 fouling-resistant membranes (DOW Fortilife). Whether the application requires cooling tower make-up for a textile dyeing plant, boiler feedwater for food & beverage manufacturing, or acting as the primary concentrator for a Zero Liquid Discharge (ZLD) facility, the design philosophy guarantees maximum uptime.
> ENGINEERING PROTOCOL: All turnkey reuse solutions undergo rigorous FAT testing. The Siemens PLC fully automates UF Chemically Enhanced Backwash (CEB) and RO flushing cycles to actively combat organic and biological fouling. The result is a guaranteed longest membrane lifespan and the lowest Total Cost of Ownership (TCO).

How the Industrial Water Reuse Process Works (Engineering Details)

Step 1: Fenton Advanced Oxidation (For High COD). For complex industrial effluents with COD up to 4000 mg/L, the process begins with a Fenton Oxidation reactor. By utilizing Fe2+ as a catalyst and H2O2, powerful hydroxyl radicals (·OH) are generated. This advanced oxidation process (AOP) breaks down refractory organics into biodegradable micro-molecules, preparing the water for biological treatment.

Step 2: Biological Effluent & UF Pre-treatment. The wastewater is biologically treated (via MBR or AO) and pumped through an Ultrafiltration (UF) skid. This crucial industrial water reuse pre-treatment stage reduces the Silt Density Index (SDI < 3) and guarantees zero suspended solids, acting as an absolute physical barrier to protect downstream membranes.

Step 3: Fouling-Resistant RO (FR-RO) Separation. Powered by premium Grundfos vertical centrifugal pumps, the filtered wastewater is forced through fouling-resistant reverse osmosis membranes (such as DOW Fortilife™). These specialized wide-spacer elements tolerate much higher organic and biological loads than standard brackish water membranes. The system recovers 65-80% of the water as high-purity permeate, leaving behind a concentrated brine.

Step 4: ZLD Pre-Concentration (Optional DTRO). For clients pursuing Zero Liquid Discharge (ZLD) or facing extreme discharge penalties, the RO brine is sent to a Disc Tube RO (DTRO) system. Operating at extreme pressures (up to 120 bar), the DTRO further concentrates the brine, recovering additional pure water and reducing the final waste volume to merely 5-10%.

Step 5: Thermal Evaporation & Pure Water Delivery. The highly purified permeate from both the RO and DTRO stages is routed back to the factory for use in cooling towers or low-pressure boilers, slashing municipal water bills. The tiny remaining volume of extreme brine is sent to a thermal evaporator (MVR/MED) for final crystallization, successfully achieving a turnkey Zero Liquid Discharge (ZLD) wastewater solution.

Hardcore FAQ.
Engineering-Grade Answers.

Standard UF+RO recovers 70-85% due to osmotic pressure limits. To achieve 100% (Zero Liquid Discharge), a DTRO and Thermal Evaporator must be added to treat the final brine.
Absolutely not. Shipping heavy, hazardous chemical liquids overseas is a massive waste of your budget due to extreme freight and customs costs. Instead, we provide the exact chemical formulas, concentrations, and dosing pump settings. You purchase these standard chemicals locally, saving thousands of dollars.
This is why UF pre-treatment is absolutely necessary (to guarantee SDI < 3). Furthermore, we use specialized Fouling-Resistant (FR) RO membranes with wider feed spacers (34mil) designed explicitly for high-organics.
Absolutely NOT. Raw sewage must first pass through a biological treatment plant (like MBR or AO) to reduce BOD/COD to acceptable levels before it can enter a membrane reuse system.
The RO permeate has TDS < 50ppm, making it superior to tap water. It is perfect for cooling tower make-up, boiler feedwater, washing lines, and general process water.
Yes. While our systems are plug-and-play and support remote video commissioning, we can dispatch our senior process engineers globally to supervise installation and train your local operators.
