Operating principle of grease and starch separators

Grease and starch separators are designed for the treatment of wastewater contaminated with fatty substances (vegetable and animal fats) and/or containing starch before it is discharged into the sewer system. These substances do not dissolve in water or dissolve only to a negligible extent (starch foams heavily), so their direct entry into the sewer system causes a number of operational problems (clogging of pipes and sewers, corrosion of equipment, unpleasant odour), which prevents the proper operation of wastewater treatment plants/sewer systems. It should be emphasised that the above-mentioned separators cannot receive "black" sewage, rainwater runoff or sewage containing light liquids and mineral oils.

Separators are flow-through devices, i.e. they mechanically separate grease from the rest of the wastewater as it flows through the system (in the case of starch, the foam formed is neutralised). The separation process is made possible by the phenomenon of flotation due to the lower density of fatty substances relative to the density of water. Due to their mode of operation, separators also retain part of the easily settling suspended solids, which accumulate in the settling chamber at the bottom of the unit (sedimentation).

The basis for the correct operation of a separator is the correct determination of the nominal flow rate (the amount of wastewater flowing through the device [l/s]). This determines the basic characteristics of the separator, such as the inlet and outlet diameter, the volume of the sedimentation chamber and the volume of the separation chamber. Grease and starch separators from Gastroservis, spol. s r. o. are designed for the treatment of process wastewater with flow rates from 0.5 to 30 l/s (standard range). At the customer's request, we also supply units with a higher flow rate.

Construction of the grease and starch separator

Grease and starch separator - Grease and starch separators in the kitchen

Application of grease and starch separators

The separators are manufactured in accordance with the PN-EN 1825-1 standard and bear the CE marking.

They are used in establishments such as – restaurants, hotels and guesthouses, catering facilities, canteens, bars, fast food - quick-service outlets, pubs, motorway restaurants, the food industry - meat processing plants, slaughterhouses, dairies, cheese factories, etc.

Advantages of grease and starch separators

- The units are manufactured in accordance with the European standard PN-EN 1825-1
- Verified efficiency ensured by the manufacturer and a notified body
- Products with CE marking in accordance with European Union directives,
- Possibility of installing the units at great depths, in areas with motor vehicle traffic, above ground level (free-standing), as well as at high groundwater levels,
- Made of PE polyethylene with a density of not less than 935 kg/m3 – low weight of the unit with relatively high strength; this material is resistant to corrosion, weathering, UV radiation and chemical compounds contained in the wastewater,
- Easy installation (low weight of the unit)
- Easy operation
- Possibility of additional equipment (extension shaft, automatic grease level sensors with alarm devices).

Automatic grease separators GS are the right solution for grease management with:

1. Verified Environmental Product Declaration
2. Global Green Tag - Platinum Health Check
3. PAS 2060 carbon neutrality.

GreaseShield removes food waste and fats, oils and grease (FOG), including saturated animal fats, protecting drain pipes from repeated blockages and expensive pump-outs, offering excellent operational, environmental and cost-saving benefits:

Operational benefits:

• The world's best grease removal unit. User-friendly, no access to the inside of the separator required.
