Decantor Vessels

Decantor Vessels are specialized borosilicate glass process vessels designed for efficient liquid–liquid and liquid–solid separation based on gravity settling. These vessels enable controlled separation of phases without mechanical agitation, making them ideal for delicate, purity-sensitive processes where visual monitoring and chemical compatibility are critical.

At Bhanu Scientific Glass Co., our decantor vessels are engineered to integrate seamlessly into glass process lines, reactors, distillation units, and pilot plants, offering reliable separation with high operational safety.

Decantor vessels function by allowing immiscible phases or suspended solids to settle naturally under gravity. Due to their transparent borosilicate glass construction, operators can clearly observe phase boundaries, settling behavior, and separation efficiency in real time

The geometry, outlet positioning, and internal fittings are carefully designed to ensure minimum turbulence, preventing remixing of separated phases during discharge.

How Decantor Vessels Work

1. Process fluid enters the decantor vessel through the inlet nozzle
2. Heavier phase or solids settle at the bottom due to gravity
3. Lighter phase remains on top
4. Separated phases are withdrawn through dedicated outlets or dip pipes
5. Visual inspection ensures controlled and accurate separation

This non-mechanical separation method reduces shear stress and contamination risk.
