The catering wastewater undergoes two-stage pretreatment:

• First stage: Basket grid or sundry separator removes large particle sundries including bones, shells, and vegetable leaves
• Second stage: Fine dregs such as rice grains and minced meat are deposited in the conical bucket for further treatment

• Solid-liquid separation device intercepts solid slag effectively
• Dedicated sedimentation tank collects small sundries and sediment for regular discharge
• Integrated solid slag bucket and oil collecting bucket maintain clean appearance
• Special overflow diversion pipes stabilize water flow and improve oil separation efficiency
• Oil temporary storage area enables high-density oil accumulation with automatic discharge
• Siphon drainage system ensures low oil content in discharged sewage with stable water flow
• 304 stainless steel fully sealed structure prevents odor and corrosion
• Complete ventilation bridge system discharges dirty air from equipment interior
• Advanced oil diversion system increases separation efficiency while reducing equipment footprint
• Temperature control probe and heating system prevent oil hardening and optimize separation

Our equipment achieves 95% oil removal efficiency, significantly outperforming conventional equipment (60%) and traditional oil separators (45%). This represents more than double the treatment effectiveness of older systems.
