Seriously poor water resources in China, per capita only 1/4 of the world average. In recent years, the rapid development of the iron and steel industry has vigorously promoted economic construction. However, a large amount of waste water is discharged during the steel production. The direct discharge of these waste water causes serious pollution to water resources and aggravates the water shortage. Therefore, increasing the recycling rate of water, reducing the consumption of new water, and realizing the recycling of waste water are not only important means for the sustainable development of the steel industry, but also a great event for protecting the environment, benefiting the nation and benefiting the people and the benefit of future generations.

Process

The whole system consists of two parts: pretreatment and reverse osmosis. The part of the reverse osmosis unit before the pretreatment part, its role is to remove suspended solids, colloids, organic matter and microorganisms in raw water, these substances easily lead to membrane fouling. Whether the reverse osmosis unit can operate normally depends very much on the reasonableness of the design and operation of the pretreatment system.
