Executive Summary

In December 2019, Shandong Huichuang Environmental Protection Equipment Co., Ltd. successfully completed and passed the official site acceptance test for a massive 400m³/h ultra-pure water treatment system engineered for Shandong Lubei Chemical Group Co., Ltd.

Designed to meet the stringent water purity requirements of high-pressure power plant boilers and large-scale chemical processing, this turnkey engineering project integrates advanced Ultrafiltration (UF), Reverse Osmosis (RO), and Mixed Bed Ion Exchange technologies. The facility delivers a continuous supply of high-purity water, protecting critical boiler infrastructure from scaling and corrosion while reducing overall chemical consumption.

Project Background & Client Challenges

Shandong Lubei Chemical Group is a renowned industrial conglomerate specializing in fertilizers, eco-chemicals, and power generation. To support its expanded chemical production lines and power plant utility boilers, the group required a high-capacity water treatment solution to tackle several challenges:

  1. Massive Volumetric Requirement: A continuous, high-volume supply of 400m³/h pure water with high system reliability (24/7 uninterrupted operation).
  2. Stringent Purity Standards: Raw water needed deep desilting and ion removal to achieve ultra-low conductivity (<0.1μS/㎝ ) and high resistivity to prevent thermal boiler fouling.
  3. Fluctuating Intake Water Quality: Complex raw water parameters demanded a resilient pre-treatment matrix to protect downstream high-precision membrane elements from rapid fouling.

Technical Solution & System Architecture

To ensure multi-stage protection and optimal energy efficiency, Shandong Huichuang designed a complete process flow combining physical pre-filtration, membrane separation, and deep ion polisher exchange:

Key Technological Highlights:

  • High-Efficiency Ultrafiltration (UF) Skid: Utilizing PVDF hollow-fiber UF membranes as pre-treatment to intercept colloids, microorganisms, and fine particles, ensuring the Silt Density Index (SDI) remains consistently below 2.0 to safeguard the downstream RO membranes.
  • Double-Stage Reverse Osmosis (RO): Equipped with premium-grade high-rejection RO membrane elements and Grundfos energy-efficient high-pressure pumps, achieving a overall desalination rate exceeding 98.5%.
  • Mixed Bed Deep Deionization: Mixed cation-anion resin polisher beds reduce residual ion concentration to micro-quantities, elevating water resistivity to meet strict power boiler feed standards.
  • Smart Automation & PLC Central Control: Outfitted with Siemens PLC and SCADA human-machine interface (HMI) for real-time online monitoring of pressure, flow rate, pH, and electrical conductivity, offering automated backwashing and CIP (Clean-in-Place) functionality.

Performance Results & Project Impact

Since its successful commissioning in December 2019, the 400m³/h ultra-pure water plant has delivered exceptional performance metrics:
