BIOSTRAINZ F.O.G™ rapidly removes fats, oils and greases along with suspended solids, nitrogenous waste and a wide range of contaminants, improving the overall efficiency of wastewater treatment plants.
BIOSTRAINZ F.O.G™ is highly recommended for influent streams with high concentrations of fats, oils, greases or hydrocarbons as processed in aerobic treatment systems, dissolved air flotation units, oil water separators and grease traps.

Key Principles of Use
There is a wide range of effective concentrations or ‘doses’ of BIOSTRAINZ F.O.G for certain applications, however the optimum range is generally between 2 and 10 milligrams per liter of volume—that is milligrams of BIOSTRAINZ F.O.G per liter of wastewater or substrate. This is roughly equivalent to parts per million.
To maximize the BIOSTRAINZ F.O.G treatment program, BIOSTRAINZ F.O.G should be kept in contact with the target substrate to the greatest extent possible. This means that when applying BIOSTRAINZ F.O.G to a large volume of wastewater, such as a large lagoon, tank or vessel, it is important to maximize the distribution of BIOSTRAINZ F.O.G throughout that medium. Additionally, the frequency of BIOSTRAINZ F.O.G dosing should match or exceed residence time within the wastewater system. For example, if a septic tank has a residence time of 14 days, then BIOSTRAINZ F.O.G should be applied at least every 14 days. If a grease trap fills and empties completely every day, then daily dosing or continuous with BIOSTRAINZ F.O.G is advised.
BIOSTRAINZ F.O.G can operate effectively in a wide range of temperatures. However, the catabolic break-down of organic waste molecules into inert compounds slows significantly as the temperature of the substrate approaches the freezing point (32°F/0°C). There is a similar loss of effectiveness at temperatures above approximately 140°F (60°C). The ideal operating temperature is between 50°F and 120°F (10°C to 49°C). This broad operating range makes BIOSTRAINZ F.O.G a suitable treatment for effluent lagoons, sludge drying beds and effluent storage basins in most climates during most
times of the year.
BIOSTRAINZ F.O.G operates within a broad pH range, from 2.5 and 9.5, but the optimum pH is between 3.5 and 8.5 with neutral preferred.
When using BIOSTRAINZ F.O.G in an aerobic process the performance of BIOSTRAINZ F.O.G can be improved by higher levels of dissolved oxygen. Optimum levels in aerobic processes are DO>1.5mg/L, however BIOSTRAINZ F.O.G is equally effective in anaerobic processes with lower DO.
Pre-Activation of BIOSTRAINZ F.O.G™
BIOSTRAINZ F.O.G-FOG is packaged in a freeze-dried powder form and delivered in vacuum-sealed bags. The powder must be pre-activated by mixing into solution with water before being applied to the wastewater or target medium.
This step allows BIOSTRAINZ F.O.G to properly culture and forms a high concentration of catalysts. Several factors govern the effectiveness of this BIOSTRAINZ F.O.G dose pre-activation phase.
The appropriate time period for preparing a BIOSTRAINZ F.O.G culture is between 12 and 24 hours. Less time may will result in a less optimal concentration of catalysts, while too much time may cause BIOSTRAINZ F.O.G to run out of its nutrient source and lose viability. Each package contains a proper amount of nutrient to sustain BIOSTRAINZ F.O.G during the pre-activation phase.
For pre-activation, BIOSTRAINZ F.O.G should be mixed into solution with water at a concentration between 2,000 and 10,000 milligrams of BIOSTRAINZ F.O.G per liter of water (parts per million). The ideal concentration is approximately 5,000 mg/L.
Because BIOSTRAINZ F.O.G is packaged with its own nutrient source, it is important to use a relatively nutrient-free source of water for pre-activation mixing.
The range of optimum temperature for pre-activating BIOSTRAINZ F.O.G is not as broad as its effective temperature range once activated. It is ideal to keep the pre-activation culture at a temperature above 60°F (16°C ) and below 100°F (38°C ).
The BIOSTRAINZ F.O.G pre-activation culture requires adequate oxygen. In some cases—particularly when large volumes of product are being mixed into a pre-activation solution—some mechanical means of aeration is advisable. In most cases it is sufficient to simply leave the solution container uncovered and exposed to ambient air throughout the pre-activation period.
Quality of Water Used
The BIOSTRAINZ F.O.G activation is a biological process. It is important that the water used does not contain any harsh chemicals, such as microbial inhibitors, that would prevent the growth of the BIOSTRAINZ F.O.G Culture.
