Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • In the actual procurement process of water treatment equipment, it is recommended to match the requirements based on key technical parameters such as treatment capacity and effluent quality. For example, in industrial ultrapure water scenarios with conductivity ≤ 10 μ S/cm, a secondary reverse osmosis configuration should be selected.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers usually have more practical experience in the field of power plant circulating water treatment or high-purity water preparation in the electronics industry.
  • For different application scenarios such as boiler feedwater or pharmaceutical purified water systems, attention should be paid to the material corrosion resistance and modular design differences of the chemical water equipment. 316L stainless steel material is more suitable for high chloride ion environments.
  • The pre-treatment unit configuration of the water treatment equipment needs to be combined with the fluctuation of raw water quality. It is recommended to add multi-media filtration and softening process units in high hardness water source areas in the north to reduce the risk of membrane fouling.
