Sustainable fat, oil and grease removal from wastewaters with BiOWiSH^® Aqua FOG

Foodservice operators know all too well that FOGs are an unavoidable result of food preparation and meal service. Still, these accumulations can lead to decreased dissolved oxygen (DO) levels and blockages in the pipelines. BiOWiSH^® Aqua FOG is a sustainable solution for removing fat, oil and grease (FOGs) from wastewater. It utilises a biological approach to quickly and effectively break down FOGs, ensuring that your wastewater stays clean and clear.

BiOWiSH^® Aqua FOG works on the solids, fats, oils, and greases to prevent pipework blockage and keep water companies from imposing hefty fines. Depending on your application, you can dose it with a small puck or tablet, dissolve it in a bucket or pail, and dispense it into the drain. By accelerating the degradation of solids in grease traps, BiOWiSH® Aqua FOG reduces sludge production, deep cleaning and pump-out costs and minimises aeration requirements for energy savings. This eco-friendly water treatment solution enables high denitrification rates in aerobic treatment conditions, eliminating the need for biomass solutions in the activated sludge.

BiOWiSH^® Aqua FOG uses live microbial cultures to generate the required enzyme chemistry in situ, resulting in rapid FOG degradation and preventing downstream solidification of fats ensuring pipework remains free flowing.

The optimal dosing rates for BiOWiSH^® Aqua FOG in grease trap treatment depend on several factors, including the water flow rate, size of the grease trap or retention times, loading of fat, oil, and grease, presence of any antimicrobial products, and treatment objectives. The recommended dosage rate, however, is 10.0 mg/L.

For systems with a retention time of less than 24 hours, the optimal dosing of BiOWiSH^® Aqua FOG is based on the daily grease trap flow rates and is best applied drip-fed into the grease trap on a continuous basis. This can be achieved by using a properly sized mixing tank and a dosing pump. BiOWiSH® Aqua FOG can be mixed into solution for up to 14 days of dosing, and the mixing tank should be flushed and rinsed before each new batch is mixed. In the case of systems with a retention time of 24 hours or more, the optimal dosing of BiOWiSH® Aqua FOG may be applied as a single daily dose by mixing it into a solution and dosing it via a sink or floor drain. We also provide this product in an easy to use puck form which can conveniently be dropped into the target areas.

BiOWiSH^® Aqua FOG is a fine off-white powder that can be stored for up to three years in airtight containers under recommended conditions. After opening, any unused portion should be kept dry and away from water, as the product is sensitive to high moisture levels.

To use BiOWiSH^® Aqua FOG, the required dosage is mixed with water (using a clean water source with chlorine levels as high as 3 mg/L) and dosed into the grease trap or any drain inlet of the grease trap. Or you can use the convenient puck which is just dropped into the target location.
