FREQUENTLY ASKED QUESTIONS | NanoTrap

What is the difference between microbes and enzymes

The correctly chosen microbial strain can produce enzymes. Enzymes can’t reproduce themselves but rely on microbes for their existence. Enzymes act as catalysts in the breakdown of FOG’s. Their activity depends on the shape of the enzyme fitting to the shape of the FOG in the reaction (very specific). The microbes detect what is the contaminant present (FOG), and within its capability, produces the required enzymes, which breaks down the contaminant, to a more biodegradable level. The microbes then digest the contaminant further.

Would I still need to clean out the grease trap when dosing microbes?

The grease trap is designed to catch all the solids coming down the drain, non-biodegradable as well. The trap will still require cleaning of the solids, but it will be at a reduced frequency and costs.

What does competitive exclusion mean?

The competitive exclusion principle tells us that two species can’t have exactly the same niche in a habitat and stably coexist. That’s because species with identical niches also have identical needs, which means they would compete for precisely the same resources. This could lead to the elimination of pathogenic bacteria (disease-causing bacteria).

Why is the issue of drain line blockage and backups (overflows) important?

Push back from the drains can release disease-causing bacteria, viruses, and other pathogens to the sanitary environment. Thus, public health, safety, and welfare can be jeopardized. This could lead to human health challenges and financial losses to you.

Are there local limits/regulations for fats, oils and greases?

Wastewater from food preparation, dishwashing, and floor washing are considered process wastewaters and are subject to local limits.

How can I ensure that my grease trap works effectively?

Your grease trap must be properly sized, installed, and maintained according to the manufacturer’s recommendations.

What does our legislation say about grease traps?

“SANS 10 252-2, as referenced by National Building Regulations (SANS 10 400 P), defines the minimum requirements for grease traps which must be installed in the drains of all catering and food processing businesses to prevent pollution of the sewers.”

Grease Traps must comply with SANS 10 252-2, which means they must have solids separated before FOG separation.  In addition, the following applies:

The General Hygiene Requirements for Food Premises and the Transport of Food (R.918/1999) corrected by Govt notice No 638 of 22 June 2018 specify that food premises must have a wastewater disposal system approved of by the local authority, and that the duties of a person in charge of food premises include ensuring that wastewater on the food premise is disposed of to the satisfaction of the local authority.

A correctly implemented Bio-augmentation programme will break down the FOG to water and carbon dioxide and will assist with compliance with regulations.

How can I tell if it is working?

You will see the difference in 4 -6 weeks from the start of your bio-augmentation treatment. There will be a reduction in odour from the grease trap. In addition to this, the grease accumulating in the trap will be different in appearance. Instead of it forming a thick solid crust on the top, the contents will remain flowing.

What happens to the microbes transferred downstream with the grease trap discharge?

They will continue to work and degrade organics in the drain line, collection system, or treatment systems downstream. They will provide benefit by degrading organics wherever they travel in the waste collection system.
