The formation of sodium nitrate factory in the production of wastewater and recycle way - Appropriate chemical industry

sodium nitrate in the process of production will produce large amounts of waste water, waste water containing part of nitrite, damage to the environment is very big, so sodium nitrate manufacturers need to deal with the waste water and recycle.

is a manufacturer of sodium nitrate in the formation of wastewater by sodium nitrite and sodium nitrate in the process of evaporation and crystallization of secondary steam condensate, the waste water recycling as a soluble alkali is the most feasible way. But in the process of production of water in and out of the system is not balanced, still there will be a part of the waste water discharge.

sodium nitrate wastewater produced in addition to being exhaust and a small number of products brought out, the other is in the process of solution evaporation and crystallization in the form of secondary steam discharge, the secondary steam condensation in condenser can be condensate containing a small amount of sodium nitrite and sodium nitrate. At present, the manufacturer of sodium nitrate will contain sodium nitrite wastewater recycle all used for the preparation of the lye, contain sodium nitrate wastewater recycling, spare parts manufacturer of water treatment systems for processing.

now, there are also some sodium nitrate vendors using intermittent transformation of evaporation crystallization process, not for these secondary steam recycling, but direct emissions, it did a lot of pollution to the air and water, must condensate recovery measures as soon as possible.

sodium nitrate manufacturers often to cleaning of equipment and pipelines, to get rid of the bottom of the channel sediment or crystallization, generally to clean up with water, after the discharge of liquid recycle, so as to achieve no pollution, efficient and safe production mode.
