Kitchen grease trap BIOMAST

for wastewaterfor restaurantpolyethylene

Description
The BioMast NG 4 grease separator reduces fat content and controls pH for wastewater from kitchens and institutional catering. Designed for kindergartens, schools, restaurants and food distribution centers serving over 400 meals/day, nursing homes and similar facilities. The system performs mechanical separation of solids and fats, combined with biological fat degradation and integrated pH regulation. It includes a dosing cabinet with bacteria and a dosing station with a peristaltic pump for controlled NaOH dosing.

How it works

• Incoming wastewater enters the separator where an initial compartment reduces flow velocity to allow sedimentation of solids and sludge.
• Fats, being lighter, rise to the surface and are separated from the effluent.
• A dosing cabinet at the inlet houses a biological dosing station and a peristaltic pump for pH control.
• NaOH (base) is dosed at the inlet to adjust acidity and meet required outlet pH limits.
• Bacteria supplied by the dosing station biologically degrade fats into CO2 and water.

Applications

• Kindergartens and schools
• Restaurants and catering operations (recommended for >400 meals/day)
• Food distribution businesses (>400 meals/day)
• Nursing homes and other institutional kitchens
