Currently in water filtration, reverse osmosis membranes and nanofiltration membranes are the most commonly used membrane elements, but many users have a vague understanding of reverse osmosis membranes and nanofiltration membranes. Today Jun Xin will introduce to you what the differences between RO and NF membranes are, as well as the commonalities and differences. Read More

Reverse osmosis membrane is the key equipment of the reverse osmosis system, the system for a long time in continuous operation, the water calcium and magnesium plasma will be constantly precipitated and attached to the surface of the reverse osmosis membrane, the formation of scaling blocking the membrane pores, which will affect the efficiency of the reverse osmosis system water, damage to the reverse osmosis membrane. As the reverse osmosis membrane is more expensive, so in the operation of the system, to increase a section of the dosing system, water treatment equipment in the water with reverse osmosis scale inhibitor, delay the precipitation of calcium and magnesium ions and membrane surface scaling.

The printing and dyeing industry consumes a lot of water, usually 100-200 tons of water per ton of textile printing and dyeing, of which 80%-90% is discharged as printing and dyeing wastewater. Commonly used treatment methods include recycling and harmless treatment. The use of membrane separation technology to remove impurities, purify and concentrate the reaction product liquid in the production of reactive dyes can not only concentrate the product, but also obtain high-quality liquid products. The system implements componentized design, with a high degree of equipment automation, which can realize PLC control, easy operation and maintenance, and easy standardized management. Read More

The food and beverage industry has a wide range of raw materials and a wide variety of products, and the amount and quality of discharged wastewater vary greatly. We have developed a feasible treatment process for soybean protein isolate and whey wastewater, extracting soluble protein and oligosaccharides separately, recycling high-concentration organic matter that cannot be easily degraded by raw materials, and at the same time ensuring that the wastewater can be reused after treatment. during production process. The application of this technology has opened up a new way to solve the problem of protein isolate whey wastewater treatment in the soybean industry. Read More

We design a closed circulation treatment and reuse system for heavy metal wastewater, which can purify wastewater and recover heavy metals. The concentration, recovery and separation technology of heavy metal wastewater not only solves the problem of environmental pollution in the industry, but also creates economic benefits for enterprises.
