The Problems Caused by Fats, Oils, Grease & Inefficient Grease Management

Technology from the late 1800s!!!

Grease Interceptors suffer from the dual problem of twin contaminant layers comprising FOGs and Organic Contaminants separated  by a layer of oxygen depleted water giving rise to anaerobic conditions. Most grease traps are undersized. It is estimated  that > 55% of the entrained FOGs will simply pass through the grease trap to cause problems down-stream.

In accordance with the European Standard EN 1825 for Grease Management Systems passive grease traps should be pumped at least once monthly and preferably every two weeks. A costly recurring expense for  an inefficient process that does not eliminate problems downstream.

Dosing systems don’t work !

According to research carried out at the request of the USA Navy (Proceedings of the International Society for Bioremediation, QUB) advised that Pseudomonas aeruginosa ,which adversely affects human and aquatic health and was responsible for the tragic deaths of babies in the Royal Victoria Hospital, Belfast, has been found to be effective in emulsifying, by means of producing bio surfactants, an  average of 74.8% of animal fats.

False Claims Made By Mechanical Grease Traps or GRU’s!

Mechanical Grease Traps or GRU’s (Grease Removal Units) are small passive traps fitted with an internal heating  element and one or more rotating discs or ball valve arrangements to remove the retained FOGs. These units have very limited retention capacities. They are not effective at dealing with animal fats, which  quickly congeal and block the transfer trough so rendering such units inoperative.

Wholly dependant upon sustained kitchen  porter maintenance which is rare, anaerobic conditions tend to prevail and the bulk of FOG contaminants pass through to  cause drainage problems. Siphoning and smoke/fire related incidents are recurring issues.


Environmental Products & Services Ltd (EPAS)

In addition to our Stockport, Manchester factory, the Company has recently acquired new factory premises to accommodate increased production demand and to accommodate an R&D facility and Laboratory. The factory is situated in Carnbane Industrial Estate which is Newry’s main industrial area, ideally located adjacent to the Dublin Belfast motorway. We export 96% of our products outside of Northern Ireland to the rest of the world. We spend 10% of our turnover on R&D, innovating and delivering cost effective solutions, and new products to assist our distributors to meet their customers needs and grow their business profitably.

How GreaseShield® works

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.

GreaseShield® is a Pro-Active Mechanical Grease Trap that operates in real time, removing food wastes. A patented design of 7 x co-operating baffles, a reverse flow configuration and recirculation of grey effluent using waste thermal energy to remove emulsified FOGs for recycling and safe disposal, via a semi submersed rotating FOG drum, having oleophilic and hydrophobic properties, which is then wiped by a silicone wiper blade, with anti friction properties, results in the ‘Best Grease Trap in the World’.
