Why a FOGFILTER unit is required
When fog is contaminated by detergents, dairy/ice cream/milk shakes, cleaning products with surfactive properties /surface-active materials it can’t be efficiently separated by most good GRU /GAD technologies. Once this fog enters into suspension, it simply cannot separate in the short time it would normally pass through a GRU/GAD system. These GRU and GAD systems are designed to separate during fast flow rates , usually between 0.75 litres per second to 3.15 litres per second.
Put simply, once fog is contaminated and goes into suspension, It becomes heavier than water and rather that float on the water to be separated, it sinks and stays mixed throughout the water for 3 days or more. This is why a GRU or GAD requires a polishing filter /cartridge to catch this fog that is deep in emulsion.
WHERE DO THESE EMULSIFIERS COME FROM WITH THE FSE ?
Typical sources for these emulsifiers within the FSE are :
Hot dairy based drinks/beverages, latte coffee and others
These products have varying effects on the waste stream /waste water depending on type of dairy product. A dairy Curd can form which is separated settled or floated phase of dairy products comprised of proteins and fats which form as a result of Calcium Phosphate at ZPC pH suspended or emulsified in the waste stream. The densities float or precipitate in various measure which can affect a GRU/GAD process.
Like Milk waste, the GRU /GAD technologies differ from one producer to another so it is difficult to cover the exact effect on each technology. Fogfilter takes the guessing out of this by helping the FSE to reduce the volume of silt that enters the GRU/GAD.
Fogfilter offers a simple solution. We advise the FSE to install a custom made stainless steel mesh basket within the Mop Drop sink to offer primary separation of the silt Reduce the volume of silt and surfactants that enters the GRU / GAD . This silt could be regularly scooped out of this mesh basket to prevent it quickly clogging up a Fogfiler unit or GRU/GAD unit. It is always simpler to separate waste at source. The waste stream is then routed via the stand alone Fogfilter unit and the clean waste effluent discharged safely to the receiving drain fog free and within the FSE’s Discharge Consent.
The waste stream can either be routed through the GRU with a bolt on fogfilter unit or via a stand alone fogfilter unit with a direct discharge to the main drain . The advantage of using a stand alone fogfilter unit on a mop drop sink is that the hydraulic load is reduced to the GRU / GAD when the mop drop waste stream is safely discharged to the main drain fog free. This will enhance the operation capabilities of the GRU / GAD.

The Fogfilter patented technology is designed to make it much simpler for Food Service establishments (FSE’ s) to meet and exceed their discharge consent standards.
