Use grease control to protect your drainage run either to a packaged sewage treatment plant or to the mains sewer.

Left unchecked, grease builds up creating horrible smells, blockages and ultimately equipment failure. You must deal with it regularly.

Grease is also the subject of legislation. Refer to Building Regulations BS8301:1985 CoP Building Drainage and The Water Industry Act 1991, Section 111.

Preactivated dosing systems

This device is usually located within the kitchen as close as possible to the main potwash area and within close proximity of a fused electrical spur, a cold water supply and a waste pipe connection to allow the biological solution to be discharged.

Usually once a day, at a regular pre-programmed time, the Grease Guzzler dilutes , heats and activates a mix of bacteria and enzyme strains which are released (dosed) into the drainage system. The solution digests grease, cooking oils and animal fats, degrading them naturally to base elements, prevent the main cause of drain blockage. As the bacteria and enzymes within the solution digest the grease they also continue to multiply which further increases the rate of biological activity and therefore the system effectiveness.

Pros
Easy to install in new and retro fit applications
Releases fully active bacteria
Works with or without a grease trap
Very effective with packaged sewage treatment plants
Dosing regime can be tailored to suit any site
Highly economical: precise product metering stops wastage
Solution breaks down into base elements leaving no harmful chemicals

Cons
Must adjust pump station control system to restrict flow for optimum bacteria contact time.

Active Electro-Mechanical Systems

These devices provide a very effective option if sited in the right location, one close enough to prevent solidification of the grease before it enters the system. They are usually located under the kitchen sink or worktop.

Kitchen waste flows into the unit, food debris is separated out, the liquid then flows into the main holding tank where the grease rises to the surface and solidifies. During low flow periods the contents of the tank are heated and the grease liquified. The integral rotating wheels then skim and lift the grease. In turn, wiper blades clean the wheels and the grease runs into a collecting channel pouring into an external container for legal disposal.

Pros
Easy to install in new and retrofit applications
Very efficient if you empty it every day
Easy to maintain

Cons
Blocks if you don’t empty it every day
Can be smelly
Location and flow rate are critical

External multistage grease traps

An effective option if in the right location, these devices separate grease and fat from other liquid kitchen waste using a series of baffles.The flow pattern created by the baffles causes the grease and fat to rise to the surface whilst at the same time encouraging the heavy food debris to fall and settle in the bottom of the trap. Location is all-important. Too far from the kitchen and the grease cools and solidifies before it gets there. You must empty the grease (and the rest of the content) regularly (once a month depending on trap size) to keep it working well.

Pros
Very effective. Will minimise disposal costs if sized correctly for the volume of waste.
Low capital cost
Easy to install on new build

Cons
Waste disposal costs are escalating
Can be ineffective if incorrectly sized
Difficult to retro-fit
Strong risk of blockage if not serviced regularly or if sited incorrectly
Can be smelly
