GreaseShield® is a Pro-Active Mechanical Grease Trap

  GreaseShield EFFUELENT  
 

GreaseShield® is a Pro-Active Mechanical Grease Trap operating in real time, taking advantage of waste thermal energy present in effluent being discharged from commercial kitchens to remove emulsified FOGs, particularly saturated animal fats before they solidify. GreaseShield® removes and dewaters organic solid matter (by means of a Pre Filter or FilterShield® and optional internal Automatic Solids Removal / Transfer system) that is typically entrained in the effluent preventing anaerobic foul smelling conditions brought about by biological activity, depleting dissolved oxygen present in the effluent. Because biological degradation of organic matter in water is substantially prevented, BOD, COD, FOG and SS loadings are significantly reduced.

GreaseShield® recirculates grey effluent internally pulsing 5 Min on 5 min off, to promote greater efficiency of FOG removal and to assist in removing “floaty” dairy products. This process avoids the usage of potable water.

GreaseShield® incorporates a vortex flow controller to regulate flow without causing an impediment to entrained wastes.

GreaseShield® Low Level units incorporate touchless sensing methods (n the process of patents being applied for), to detect FOGs by innovative means and in conjunction with a PLC controller transfers the FOGs to the main GreaseShield® unit for safe removal. Grease is prevented from solidifying before safe removal.

All GreaseShield® units incorporate zero maintenance FOG removal means to provide maximum contact with effluent internally. The Removal Means is pulsed 5 Min on 5 min off, to promote greater efficiency of FOG removal.

   
  Inside the GreaseShield   The internal of all GreaseShield® tanks are manufactured from virgin random polypropylene co-polymers that are tolerant of high temperatures and resistant to changes in pH levels.

The tanks are injection moulded in one piece and then contained with a 304 Stainless Steel Cabinet.

The choice of material avoids the problems experienced by polyethylene which reacts and contributes to the production of malodours which is exacerbated by anaerobic conditions associated with food waste remaining in water at a typical temperature of 40 Celsius.

 
 

GreaseShield® fitted with Prefilters and / or FilterShields® are equipped / issued with a Water Spray gun and hose to facilitate clean down of the inside of the Prefilters and / or FilterShields®.

GreaseShield® units have integral anti-flood and recalibration procedures and are supplied with threaded bleed screw sampling points to enable end users to sample the discharge effluent without the need for any tools.

GreaseShield® units support in situ bioremediation by passing effluent through a series of co-operating magnetic baffles comprised of maintenance free wet type anisotropic barium ferrite magnets which are axially magnetised. The magnetic baffles have three purposes.

 
 

These are :-

  • the electro-magnetic processing of waste water effluent to prevent scaling of sewage pipework by calcium and metal deposits which is a contributory factor to blockages recurring in sewage systems in areas where the water is hard or mineralised.
  • to contribute to the lathering effect of the wetting agents typically found in commercial surfactants and making them more readily available (soap lathers easily) in breaking down accumulations of FOGs in the sewage system.
  • Passing indigenous bacteria (entrained in effluent) through the magnetic fields alters the cell walls permitting the absorption of mineral crystals. Filter life is also extended with co-operating magnetic water treatment, i.e. slime build-up is reduced. This is attributable to the consumption of polysaccharides by the magnetically affected bacteria. Accumulation of algae downstream is inhibited by virtue of the organic and inorganic matter having been bio converted.

GreaseShield® LL units deal effectively with either Convection or Steam Combi ovens and are designed to accept the effluent discharge from double stacked ovens and floor length ovens.

Kitchen staff are discouraged from accessing the internal of the GreaseShield® units. The Lids have an integral SS lock to prevent unauthorised access.

Greaseshield® is pioneering the harvesting of a renewable energy resource.

GreaseShield® has an electrical consumption of 16 watts per hour. This compares to GRU models, the smaller models of which have an electrical consumption of 1500 watts per hour or 93.75 times more than a GreaseShield® LL Unit. The difference is accounted for by the fact that GreaseShield® utilizes waste thermal energy.

All GreaseShields® are issued with laminated wall posters re Best Practice Management and Do’s and Don'ts, to overcome the problems associated with high turnover of staff and ongoing training.
