Industrial pure water

Characteristics of industrial pure water

—— "Basic water source" for high-quality manufacturing in all walks of life

Industrial pure water is widely used in many industries such as electricity, chemical, electronics, photovoltaic, medicine, food, machinery, etc., and is an indispensable key medium in the production process. Although its water quality is not as strict as ultrapure water, it still has high requirements for indicators such as conductivity, organic matter, hardness and suspended solids. Once the water quality does not meet the standards, it will directly affect the equipment operation efficiency, product quality and even safety.
Typical characteristics of industrial pure water include:
Strict conductivity requirements: Depending on the industry use, the conductivity of industrial pure water generally needs to be controlled at <10μS/cm, and <1μS/cm may be required in power plant boiler water replenishment, battery manufacturing and other fields.
Almost no hardness and impurities: The concentration of calcium and magnesium ions is close to zero, and the total hardness needs to be controlled at <0.03mmol/L to avoid scaling, corrosion and other problems.
Organic matter and microbial control: TOC is controlled at ≤500ppb, and the number of bacteria is controlled at ≤100CFU/mL, meeting the needs of industrial-grade water quality cleaning.
Strong continuous operation stability of the system: The pure water system needs to support 7×24 hours of continuous water supply and have protection mechanisms such as automatic monitoring and abnormal interlocking to ensure the stability and uninterrupted production line.

Huadian Capabilities

As an experienced water treatment general contractor, Huadian deeply serves the water use pain points and refined needs of industrial users, and provides customers with a complete industrial pure water solution, from raw water testing, system design, equipment selection to installation, commissioning and operation services, to build a set of efficient, economical and easy-to-maintain pure water systems.

Professional process customization

According to the raw water source (well, municipal, tap water) and the purpose of water production, the "multi-media filtration + activated carbon + reverse osmosis + EDI or mixed bed + ultraviolet disinfection" and other processes are flexibly combined, and the water conductivity can be as low as 0.2-5μS/cm.

Automated control system

Equipped with PLC + touch screen + online conductivity monitoring system, it realizes water quality visualization, intelligent operation and alarm automation.

High-standard equipment selection
