How BioRestore® All Natural Treatment Saves You Money

Grease Trap and Grease Interceptors

Overview

  • In most municipalities building codes require the installation of grease interceptors wherever fats, oils, and greases (FOG’s) could be discharged into the sewer system.
  • A grease trap or grease interceptor is a passive plumbing control device designed to reduce the amount of organic material such as FOG’s, sludge, slime, and fatty acids that enter the sanitary sewer collection system.
  • Grease traps and grease interceptors work by providing a “retention chamber” that is designed to slow the drainage flow, so as to permit greases to float and solids to settle in the chamber. This then allows less polluted water to exit through the drain lines and into the sewer system.
  • Within the retention chamber microorganisms degrade the organic material as part of their natural biological processes. Increased biological activity results in a lower level of organic residuals, and a higher “retention capacity” of the retention chamber.
  • Increased biological activity also reduces odours and corrosive acids emanating from the grease interceptors and drain lines.

“Why Problems Occur” – Biofilms Bind with FOG’s, Create Blockages, and Corrode Pipes

A biofilm is a group of microorganisms in which cells stick to each other on a surface. The biofilm is held together and protected by a matrix (glue) of secreted polymeric compounds called extracellular polymeric substance, and can virtually grow on any surface including branch lines, verticals, and horizontals. The matrix has the ability to entrap organic matter, and creates channels within itself to allow bacteria deep within the biofilm to have access to nutrients carried by the convective flow of water.

The formation of biofilm or slime begins with the
attachment of free-floating microorganisms in the
wastewater sanitary drainage system pipes. Once
colonization has begun, the biofilm grows through
a combination of cell division and recruitment.
 
  • Biofilm formations are likely to contain various structures where microbiologically induced corrosion (MIR), and bio-fouling such as ammonia gas, hydrogen sulphide, dimethyl sulfide, and butyric acid will cause problems to different types of pipes.
  • Biofilm formations, much like fats, oils, and greases build up, can cause blockages, back ups, corrosion, and pipe perforations in sanitary drainage systems.
  • Waterless urinals and low flush toilets also may lead to further pipe corrosion. The pH of urine can vary between 4.6 and 8, and levels below 6.2 favour the sulphate reducing bacteria.
  • In general the higher the acidity or the lower the pH is, the greater will be the corrosion activity.

 


“Why Problems Occur” - Melting Temperatures for Fats, Oils, and Greases

Whether fats, oils and greases turn to solids or remain in a liquid state depend on their melting point. If the water temperature in the pipes and drains is below the melting point of FOG’s, problems of sticking to the pipes and/or the biofilm is more probable, and clogging and back-ups can occur. FOG accumulation consisting of products such as butter, buttermilk, chocolate syrup, mayonnaise, ketchup, mustard, and salad dressings have a severe corrosive effect on cast iron and not recommended for any use.

Grease Trap and Drain Line Treatment

Drain lines are designed to flow at a specific rate:

  • Wastewater flowing in a vertical pipe adheres to the pipe’s walls, acting like a sleeve of water with a hollow core of air. This tends to squeeze the effluent flowing at 4.5 meters per second in the vertical, and 1.2 to 2.4 meters per second in the horizontal pipe.
  • As the water temperature drops more FOG’s solidify and can more easily attach themselves to the pipe’s inner walls and/or the biofilm.
  • When FOG’s build-up on the sides of the drain line pipes, their flow is reduced.
  • A one-half-inch build-up on the inside diameter of a four-inch drain line will cut the flow rate by about 50%. Non-organic material can become imbedded causing furthe blockage and back-up problems.
  • When a blockage occurs in the sewer system, it may cause a back-up of raw sewage and/or odours into businesses, homes, or overflow onto local streets, properties or public areas. This can affect you in several areas:
    • Property damage
    • Environmental impacts
    • Fines and penalties

 


 

Municipal and Commercial Wastewater Concerns

 


 

BioRestore® All Natural Grease Trap and Drain Line Treatment
Why It Works

BioRestore® All Natural Grease Trap and Drain Line Treatment improves the microbial habitat in the retention chamber, which then allows for a higher rate of organic biodegradation.

BioRestore® is a proprietary liquid reagent that “enhances and accelerates” the natural biodegradation process that occurs in the retention chamber and in the drain lines. The reagent optimizes bioreactor conditions that promote higher biomass counts.

BioRestore®:

  • protects the microorganisms from toxic
    chemicals, pollutants, and toxins that
    otherwise could kill them, or inhibit their
    respiration and growth, and
  • provides them a greater number of
    locations to set-up colonies and grow.
 

The microorganisms breakdown organic material such as fats, oils, greases, solids, and slime, and assimilate them in their metabolic process.

 


 

Implement Best Management Kitchen Practices (BMP)

  1. “Never” pour fats, oils, and greases down the drain
  2. Use a spatula or paper towel to remove excess FOG’s from utensils, dishes and cooking equipment prior to cleaning
  3. Use screens or traps on sink and floor drains to prevent food scraps from entering wastewater pipes
  4. Establish a procedure for cleaning up fat, oil, and grease spills
  5. Store oil in areas isolated from floor drains
  6. Store fat, oil, and grease to be recycled in closed containers isolated from storm drains
  7. Use water below 140°F/60°C in all sinks connected to a grease trap. High temperature water will dissolve grease in the grease trap and allow it to cool and solidify farther along the wastewater system
  8. Train your staff

 


 

Operations
