Tank farm sewage tank
Thread Content
In the past, for atmospheric pressure storage tanks, the drains for wastewater after water separation were equipped with wastewater tanks measuring 800x800. These days I see that many designs no longer include such tanks; I’m not sure whether they should still be provided
Is the purpose of setting up a sewage tank to prevent splashing? Currently, regulations require that sewage be transported in a sealed manner; discharge to the ground is not allowed, so such systems are generally not installed. In reality, many repairs are carried out by the users themselves.
We’re not performing closed-discharge either; the waste is discharged into the drain. Which standard requires closed-discharge?
Unified Provisions for the Professional Design of Water Supply, Drainage and Fire Protection 20130106
The oil and wastewater systems are not permitted to be drained directly to the ground, in accordance with the Unified Regulations for the Professional Design of Water Supply, Drainage, and Fire Protection
The water after cutting off the flow is drained through the floor drain into the oily wastewater tank; we have a design for this.
