Recently, I have come across a lot of customers, are cleaning wastewater, such as laboratory cleaning wastewater, production process of ultrasonic cleaning wastewater, surface treatment processes in the cleaning wastewater and so on. In the Suzhou Taihu Lake area, any nitrogen-containing or phosphorus-containing substances added to the production process are characterized as nitrogen-containing and phosphorus-containing wastewater, and are therefore subject to zero discharge.

The so-called zero discharge means no discharge, all recycling. Many customers do not have very high requirements for reuse water, basically as long as the colorless and tasteless, no particulate impurities can be used, so customers think that as long as the simple precipitation can be. In fact, this is not the case, simple precipitation can only deal with particulate impurities, the salt in the water can not be dealt with, if the wastewater has been recycled, it will lead to more and more salt in the water. So much so that it can not be recycled in the end. Therefore, even if the cleaning wastewater, to do zero-discharge, also need evaporator to remove salt.

  Suzhou Rongxuan Environmental Protection, a scientific and technological enterprise specializing in the production of low-temperature evaporators, can provide customized evaporators to meet the specific requirements of customers.
