Closed discharge
Thread Content
In order to reduce environmental pollution and enhance operational safety, how can the sulfur-containing sewage in the device be discharged in a closed manner, and at the same time, consider the discharge of condensate during shutdown and purging?
Set up an underground collection tank, and then set up multiple discharge collection main pipes (which can be buried underground) to collect them and discharge them into the underground tank. Set a discharge connection point at the low point of the equipment or pipeline (you can set up a backwash or fixed discharge pipeline) and connect it to the discharge collection main pipe with a pipeline. The liquid collected in the underground tank is pressurized by a submersible pump and discharged into the sewage treatment system.
Take the ground wire...what you said above is also of great reference value.
