63. For the wastewater discharge from the spray tower, is it better to have a separate outlet at the pump exit, or to install an automatic drain valve in the circulation tank along with a level-sensitive mechanism for automatic wastewater discharge?
The wastewater from the spray tower can be discharged through a separate line at the outlet of the spray pump, or an automatic drain valve and a level-sensitive mechanism can be installed in the circulation tank to discharge the wastewater automatically; the choice depends on the actual circumstances. If the amount of waste water discharged is small, a separate pipeline can be connected at the outlet of the spray pump for treatment ； If the amount of wastewater discharged is large, it is recommended to install an automatic drain valve in the circulation water tank, as well as a level-controlled system for automatic wastewater discharge. .
……It seems better to connect a separate pipeline at the outlet of the circulation pump. Generally, wastewater needs to be put into containers and transported to another location for recycling, which makes it easier to load it into containers; whereas the circulation water tank is usually located at a low height, which poses difficulties :)
