As an advanced membrane separation water purification equipment with performance between ultrafiltration and reverse osmosis, the nanofiltration water treatment system adopts a unique nano-scale membrane pore size and charged membrane structure. Relying on the dual purification principles of size exclusion and charge repulsion, it has strong selective water treatment capacity. It is also a core promoted solution for deep water purification, water softening and water resource reuse launched by Qingzhou Foren Water Treatment Equipment Co., Ltd.. Different from the single purification effect of conventional filtration equipment, the nanofiltration water treatment system does not carry out full desalination of water. While effectively intercepting various impurities and harmful pollutants in water, it can reasonably retain minerals beneficial to human bodies and production, adapting to the water purification and quality improvement requirements of various working conditions.
In practical engineering applications, the nanofiltration water treatment equipment is suitable for the purification of most common water sources. For municipal tap water, the equipment can complete in-depth water purification, effectively remove residual trace organic matter, pesticide residues, antibiotics and various disinfection by-products in the water, simultaneously reduce water hardness and improve drinking water taste, so as to produce safe and high-quality drinking water. For surface water such as rivers, lakes and reservoirs, as well as underground well water with excessive hardness, nitrate, sulfate and fluoride, the nanofiltration system can efficiently remove natural organic matter, colloidal impurities, color and peculiar smell in the water, achieve an ideal balance between water desalination purification and mineral retention, and fully ensure stable and qualified water supply quality.
In the field of industrial water treatment, the nanofiltration water treatment system of Qingzhou Foren Water Treatment Equipment Co., Ltd. also plays a key role. It is widely used in the production wastewater treatment and reclaimed water reuse projects in textile printing and dyeing, electroplating, petrochemical and many other industries. It can not only effectively separate and recover valuable materials such as heavy metals and dyes in wastewater to improve resource utilization rate, but also realize high-proportion recycled reuse of wastewater, helping enterprises save water, reduce consumption and achieve green production. It can also complete advanced purification treatment for highly difficult wastewater such as landfill leachate. At the same time, the system can also be used as an excellent pretreatment process for seawater desalination projects. It effectively removes calcium and magnesium hardness ions and sulfate ions from seawater, avoids scaling problems of subsequent reverse osmosis equipment from the source, reduces the operating load and energy consumption cost of the entire seawater desalination system, and improves the operational stability and service life of the whole water treatment project.
With the core technical advantage of selective separation, the nanofiltration water treatment system can efficiently remove bacteria, viruses, colloids, macromolecular organic matter and divalent ions such as calcium and magnesium in water, and realize water softening and partial desalination as required. It is a preferred comprehensive water treatment equipment covering domestic drinking water purification, industrial production water quality improvement, wastewater reuse and seawater pretreatment.
