Our Engineering Standard

The Wandong Protocol

We don't guess. We engineer. Every system goes through this 5-step validation before it leaves China.

1. Water Analysis

You provide raw water report (TDS, pH, Hardness).

2. Site & Power

We confirm Voltage (V/Hz) and installation space.

3. Simulation

We perform professional ROSA / WAVE simulations to generate precise P&ID drawings.

4. Tier-1 Parts

Assembly with Grundfos, Dow, Schneider components.

5. Visual FAT

Live Video run-test before you pay the balance.

Select By Source

We categorize solutions by your water input TDS (Total Dissolved Solids).

TDS < 10,000 ppm

Ground / Brackish Water

Ideal for Boreholes, Wells, and High-salinity groundwater.

  • BWRO Membranes
  • SS304/316 Piping
  • Anti-scalant Dosing
