Component Specifications

Definition
The collection bowl is a precisely engineered vessel within oil-water separation systems designed to receive and temporarily store separated oil, water, or sludge phases after gravitational or centrifugal separation. It features calibrated volume capacity, strategically positioned inlet/outlet ports, and often includes level sensors, sight glasses, or sampling valves for process monitoring. This component ensures controlled retention time for phase stabilization, prevents re-mixing of separated fluids, and facilitates batch or continuous discharge according to system automation protocols.
Working Principle
Operates on gravitational settling and phase separation principles where separated fluids flow into the bowl based on density differentials. The bowl provides quiescent conditions for final separation, with internal baffles or weirs preventing turbulence. Fluid layers form distinct strata (oil on top, water middle, solids bottom), with discharge mechanisms (pumps, valves, siphons) removing each phase independently at controlled rates to maintain separation efficiency.
Materials
Typically constructed from corrosion-resistant materials: 304/316 stainless steel (food/pharmaceutical), carbon steel with epoxy coating (industrial), polyethylene/polypropylene (chemical resistance), or glass-reinforced plastics. Material selection depends on fluid chemistry, temperature (typically -20°C to 120°C), pressure rating (0-10 bar), and compliance requirements.
Technical Parameters
  • Capacity 5-500 liters
  • Surface Finish Ra ≤ 0.8 μm (sanitary), 1.6-3.2 μm (industrial)
  • Wall Thickness 3-10 mm
  • Connection Ports DN25-DN100 flanged
  • Temperature Range -10°C to 80°C
  • Operating Pressure 0-5 bar
Standards
ISO 13500, DIN 19569, ASME BPVC Section VIII

Frequently Asked Questions

How often should collection bowls be inspected?

Weekly visual inspections for leaks/corrosion, monthly internal inspections for sediment buildup, with full cleaning every 3-6 months depending on contaminant load.

Can collection bowls handle emulsified oils?

Standard bowls require pre-treatment for emulsions; specially designed bowls with coalescing media can handle partially emulsified fluids up to 15% emulsion stability.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
