Fat, oil and grease, hereafter referred to as FOG, can clog wastewater collection and treatment systems, septic tanks and holding tanks causing sewage spills, manhole overflows, property damage, environmental problems, and health hazards. Typically, animal and vegetable based oil and grease generated by restaurants and fast-food outlets that do not have adequate grease control measures in place, are the main contributors to these problems.
When fats, oil, or grease are washed into the plumbing system, through kitchen sinks and floor drains, they stick to the inside of sewer pipes. Over time the fat, oil and grease builds up and eventually blocks the entire pipe, causing sewage backups and overflows.
ESFR - FOG (Fat, Oil and Grease) Reducer is a sewage and lagoon treatment formulated for use in treating wastewater containing high levels of grease, fats and oil.
ESFR - FOG Reducer loosens, liquefies and degrades heavy grease deposits. It is effective in degrading extra cellular polymers, which cause foaming, and suppressing the growth of the filamentous organisms by affecting the structure of the filaments.
There are several types of grease.
Brown grease is floatable fat, oil, grease and settled solids recovered from grease control devices. Typically, brown grease is not reusable and is generally disposed of through wastewater treatment facilities.
Yellow grease is fat, oil, and grease that is not contaminated. Yellow grease is also referred to as recyclable. FOG detergents, that claim to dissolve grease, simply move grease down the pipe and create a larger problem downstream.
We tested the effectiveness of using ESFR - FOG Reducer on a wastewater lagoon.
FLOW RATE: 600 kg/day
INFLOW CONSTITUENTS: Protein 50% - Fat, Oil & Green 30% - Water 20%
TEST DATE: August 26, 2008
We next applied ESFR - Fog Reducer and ESMS - Micro Nutrient Bio-Stimulant.
In waste treatment environments, biological activity is a function of the micronutrients and bio-stimulants available to sustain and develop healthy biomass.
ESMS - Micro Nutrient Bio-Stimulant is a non bacterial, concentrated formulation derived from natural plant extracts, and designed to stimulate microbial activity in aerobic and anaerobic environments.
ESMS - Micro Nutrient Bio-Stimulant is an environmentally safe, broad spectrum product for use in waste water treatment plants, manure lagoons, oil spill cleanup sites, sewage treatment plants, sewage lagoons, municipal landfills, hydrocarbon bioremediation projects, composting facilities, etc.
