It decreases the heat transfer efficiency and causes corrosions under deposit, which shortens the service life of the equipment.
the corrosion caused by circulating water is mainly electrochemical corrosion. Contributing factors are equipment manufacturing defects, oxygen in the water, corrosive ions (Cl-, Fe2+, Cu2+), and microbial mucus slime. If the corrosion is not controlled, the heat exchanger and pipeline will be damaged in a short period.
the circulating water is suitable for the growth and reproduction of microorganisms. This is because of the sufficient dissolved oxygen, proper temperature and eutrophic conditions. Without timely control, this will rapidly leads to the deterioration of water quality and mucilaginous deposition. The heat transfer efficiency will decrease substantially and increase the equipment corrosion. To prevent this, microorganisms in the circulation water treatment must be controlled. Treatment and recycling of the cooling water can significantly save the water resource and reduce the environmental burden. Pretreatment and demineralization is an effective process. The Xiga or Aquaflex membranes are the ideal solution to control suspended contaminants and microbiology in the water and protect further downstream demineralization process running with safety, reliability and lower maintenance.
We offer the unmatched superior expertise in UF membranes. The membranes can help achieve safe, reliable, and sustainable operation of the water as pretreatment of RO membrane used for boiler feed makeup and cooling water recycling.
