CE Certification Water Reuse And Recycling Suppliers & Manufacturer

To accurately design and engineer a multi-stage water reuse and recycling system, we require an in-depth raw water analysis including: Total Dissolved Solids (TDS) or electrical conductivity; specific cation/anion balance (calcium, magnesium, barium, strontium, sulfates, alkalinity, chlorides); reactive and colloidal silica (SiO2); Chemical Oxygen Demand (COD/BOD); Total Organic Carbon (TOC); free oil & grease; Silt Density Index (SDI15) or Turbidity (NTU); and heavy metal concentrations (iron, manganese). Additionally, operating temperature ranges, desired permeate recovery rate (typically 75% to 92%), daily throughput capacity (m³/day or GPD), and available site utility power ratings (voltage, frequency, phase) are required.

Our CE certification is supported by certified Technical Construction Files (TCF) audited in alignment with European Notified Bodies. For electrical and control panels, we design and build in strict adherence to the Low Voltage Directive (2014/35/EU) and Electromagnetic Compatibility (2014/30/EU), utilizing CE-rated components. For mechanical assemblies, compliance with the Machinery Directive (2006/42/EC) and EN ISO 12100 is demonstrated via comprehensive risk assessments and interlock designs. When pressurized vessels, piping networks, and membrane housings exceed Category I thresholds, the Pressure Equipment Directive (PED 2014/68/EU) is fulfilled with full material traceability and hydrostatic test documentation, ensuring smooth site permitting across EU member states.

High-ratio water reuse from chemical, textile, or food processing operations often carries elevated COD and biological activity. We address this using a tri-stage barrier philosophy: First, advanced pre-oxidation (ozone or advanced oxidation processes - AOP) coupled with biological aerated filters (BAF) or ultrafiltration (UF) reduces COD and eliminates suspended solids down to SDI < 2.5. Second, specialized anti-fouling reverse osmosis (FR-RO) membrane elements with 34-mil feed spacers and modified hydrophilic surfaces are configured to limit biomass adherence. Third, our programmable automated clean-in-place (CIP) skids feature automated chemical batch heating, bi-directional flushing, and pH-adjusted cleaning regimes to maintain membrane flux throughout operation.

Yes. For harsh maritime coastal environments, offshore platforms, or high-salinity chemical sites, our containerized envelopes are fabricated from heavy-gauge Corten steel with high-durability epoxy-polyurethane marine-grade paint systems (C5-M corrosion category). Internally, all structural skids undergo hot-dip galvanization or are welded from 304/316 stainless steel. Wetted piping manifolds handle corrosives through Duplex 2205/Super Duplex 2507 stainless steel or schedule 80 UPVC/PVDF piping. Standard high-cube containers are insulated with mineral wool sandwich panels and equipped with industrial corrosion-resistant HVAC systems to maintain optimal electrical operating conditions.

Standard skid-mounted units (10 to 50 m³/h capacity) maintain an accelerated production timeline of 4 to 6 weeks from approval of final P&ID and mechanical drawings. Customized multi-train Zero Liquid Discharge (ZLD) plants or explosion-proof ATEX-rated oilfield produced water systems typically require 8 to 12 weeks. Every unit undergoes complete mechanical, electrical, and pressure testing (FAT) with wet tests before packing. Overseas logistics are routed through Shanghai Port via standard ocean container (20GP, 40HQ) or flat-rack carriers, accompanied by export crates and rust-preventive packaging.

We deploy a hybrid operational support model: Every system is fitted with an industrial edge IoT router that connects securely via VPN to our Shanghai telemetry center. Our process engineers monitor differential pressures, permeate conductivities, flows, and valve statuses in real-time, assisting local technicians with troubleshooting and baseline normalization. For on-site commissioning, our field engineers travel to customer project sites across Europe, Southeast Asia, South America, and the Middle East to supervise piping tie-ins, coordinate electrical loop testing, verify instrument calibrations, and conduct classroom and hands-on training for plant operators.
