What causes grease build-up in commercial/industrial kitchens?The main source of grease in a kitchen can be attributed to pot/plate washing sinks, steam ovens and floor drains. Grease Guardians can also treat pre-rinse sinks for dishwashers.
What is a grease trap and why do I need one?Grease traps have been around for more than 100 years. The concept is quite simple. Wastewater (usually from commercial kitchens)containing fats, oils and grease (or simply F.O.G.)enters a receptacle. F.O.G. does not mix with water and as F.O.G. is lighter than water it rises to the top. The clear water escapes under an outlet baffle. A traditional grease trap needs to be opened and the F.O.G. pumped out once a month.(an Automatic Grease Guardian removes the trapped grease automatically every day).Without the inclusion of a grease trap in commercial kitchens the health and safety of the establishment may be compromised. Grease will cause blockages and foul odours if left untreated. It is common for government bodies to fine owners who fail to install some form of grease treatment and consequently create grease problems. Remember, your grease may be causing someone else trouble and it is usually not difficult to trace the source of the problem.
What are the common forms of treating grease?There are various ways of treating grease. A static grease trap can be installed under ground and collects grease over a period of several weeks. The trap then needs to be emptied to maintain efficiency. Automatic Grease Removal Devices (Grease Guardian) perform the task of other grease traps but also remove the grease daily and provide the highest efficiency if looked after correctly. Enzyme, bacteria and other chemical treatment can be used to attempt to break down grease. These systems work by dosing solutions down pipework at regular intervals. Grease Guardian recommends using dosing systems when no other option is available.
Why is Grease Guardian the best solution?At FM Environmental Ltd, we believe that the Grease Guardian is the most efficient form of grease treatment on the market as the Grease Guardian is installed at the source of the problem and removes grease on a daily bases. In-ground traps lose efficiency as grease builds up obliging regular cleaning, which can prove costly over time. Enzyme systems though useful at removing some grease from pipes and traps can emulsify grease and pass the problem on to someone else once the grease solidifies again. Compared to direct competitors our biggest advantage is quality. The Grease Guardian unlike its’ closest rivals does not use moulded plastic to hold liquids, instead the tank is fully sealed stainless steel. The Grease Guardian has also the highest capacity per flow rate category meaning that much more grease will separate and can be stored within the tank compared to other brands. The Grease Guardian employs a energy efficient back up heating device to ensure even tough solid fats are skimmed. We back up our quality claims with up to 10 years warranty. The Grease Guardian is a modern way of treating an old problem.
What is a Fatberg?A Fatberg is a congealed blob of grease, sometimes as big as a bus, that block sewer lines and cause flooding. Fatbergs form over time when fats, oils and grease from commercial kitchens cling onto wet wipers, toilet paper and other solid waste allowed into the sewers. They cost thousands in repair work every year in most major cities. Click on our FATBERG SURVIVAL GUIDE for more details.
I am not happy with my current grease treatment system, what is the problem and what should I do?Passive Traps – Unfortunately, unless maintained every couple of weeks grease trap efficiency will drop and grease will escape or build up and overflow. This is common where the grease trap was undersized or business has expanded. You need to empty your system at least once a month but this can prove costly.Perhaps an Automatic Grease Removal device should be considered. Grease Guardian can be installed at the source of the problem, i.e. potwash sinks, ovens etc. and will extract trapped grease each day preventing any grease build up that could result in a drop in efficiency. Enzyme/Bacteria systems – These systems may not break down the grease efficiently and allow the grease to build up. Furthermore, they need to be topped up regularly, which can prove costly. Your local council may be unhappy that you are using such a system as it takes grease away from your premises only to see it reform somewhere else. Other Grease Removal devices though claiming high flow rates actually have very small tank sizes and therefore allow grease to escape easily. Many are made of plastic which is prone to leaks. A Grease Guardian protects you and the local environment and does not require enzymes or bacteria.
What can be done with waste grease collected from Grease Guardians?Grease collected by Grease Guardians should be stored in the same way as spent fryer fat and given to grease rendering companies who will recycle the waste. This is common practice in most markets and costs little if anything. Grease is being increasingly used in the preparation of bio-diesel. Demand for grease for this purpose is therefore growing.
How exactly does a Grease Guardian work?Waste enters the Grease Guardian and solids are collected in a strainer basket. The wastewater continues into a second chamber where it separates into clean water and waste grease and oils. The clean water passes under a baffle and out of the unit and the grease and oils rise to the top of the chamber where, through a periodic system of heating and skimming, they are removed and collected into a container that can be taken away. No enzymes or chemicals are required to assist in the process.
Does the Grease Guardian only work if the heating element is running?No. Instead of having the heating element running all day and all night, we conserve energy and yearly costs by only heating the grease for 2 hours per day which is the normal daily requirement and only when the temperature of the effluent is less than 40 degrees. The grease will remain trapped inside the unit for between 12 – 24 hours until it is skimmed off as part of a 2 – 3 hour period of “heating and skimming”. In economy mode the heater can be turned off.
What maintenance does the Grease Guardian require?A Grease Guardian requires daily maintenance that takes no longer than a couple of minutes. This involves simply emptying the removable solids basket and plastic grease container. It is recommended to clean the wiper-blades regularly. It is also a good idea to empty the unit completely and clean the inside every 4 – 6 months.
Are Grease Guardians suitable for installation inside kitchens?The Grease Guardian is ideal for kitchens. The product is CE rated and therefore complies with latest European safety standards. Grease Guardian has achieved HACCP on its grease removal units. Food Hygiene is not compromised in the stainless steel Grease Guardian.
How do I choose a Grease Guardian to suit my requirements?The sizing of a Grease Guardian depends on the kitchen appliances entering the unit. For an idea of what unit best suits your establishment contact your local distributor.
Do I need to connect my dishwasher?The general policy is not to connect dishwashers to Grease Guardians although some very small units can be connected without adverse effects. The effects of emulsification by dishwasher detergents can cause oil and grease to pass through any grease trap in suspension. Therefore where possible fats, oils and greases must be restricted from entering dishwashers. The adoption of good housekeeping practices is required from the outset to maximise efficiency. FM recommends rinsing down all utensils into a pre-rinse sink that is connected to a Grease Guardian. Heavier solids should be scraped into a bin prior to rinsing.
Where is the Grease Guardian sold?The Grease Guardian has been sold in over 40 countries worldwide. For 20 years the system has been supplied to the top hotel, restaurant, supermarket and fast-food chains aacross the globe. For a reference near you contact us.
Does the Grease Guardian have moving parts?Yes, as do nearly all effective machines. Some argue that moving parts are a negative feature as they deprediate over time. The Grease Guardian has few moving parts (wheel, motor and gears). They operate for only 30 to 60 mins a day and have a very long life expectancy. Other systems rely on natural processes which are often hard to control and predict, where as the Grease Guardian is guaranteed to do what it is programmed to do.
