Frequently asked questions about Bio Green 100, 200 and 300:

What is Bio Green 100, 200 and 300?

Bio Green UK Ltd 100, 200 and 300 is a blend of friendly microbes, nutrients, and preservatives. The microbes in Bio Green’s products have been specially selected from many non-toxic naturally occurring microbes as the best solution to treat grease traps and sewer drains that are subject to blockages caused by large amounts of oils, fats, greases and other organic matter passing through them.

The blend of microbes form a bio-film releasing a continuous and renewable supply of highly active enzymes into the water flow for fat, oil and grease degradation.

The bio-film adheres to the walls of the grease trap and drainage system and unlike conventional enzyme systems is not washed away. Bio Green products have a significant resistance to disinfectants and other cleaning fluids.

Where would you apply Bio Green?

The primary application of Bio Green products is as a maintenance tool to treat fats, oil and grease in the grease trap and to prevent grease and fat build-up in the sewer system.

It is used extensively in places where food preparation and processing produce large quantities of waste water with a high proportion of grease and fat which, if left untreated can often block or restrict the flow of drainage systems. This causes mall odours and unhygienic conditions, which invariably leads to expensive and inconvenient clearing of the drain system.

What are the benefits of Bio Green?

Regular dosing with Bio Green 100, 200 and 300 will:

  • Reduce the frequency of grease trap emptying by up to 70%
  • Eliminate blockages in the sewer system (Fatbergs)
  • Eliminate the risk of Fatbergs forming in the drains
  • Eliminate odours
  • Eliminate the need to use hazardous chemicals in drain treatment
  • Eliminate the need to remove grease in drains manually using rods
  • Provide an improved working environment
  • Will not damage drain walls or bonding
  • Reduce BODs, CODs, TSS and FOG which will have a positive effect on effluent costs
  • Should be cost neutral to the end user due to the reduction in trap emptying and emergency call outs. Grease trap emptying will cost an average of £250 per visit
Does the Bio Green product contain live micro-organisms?

In our Bio Green formulations, the active ingredient is a live bacterium. These bacteria were specifically selected from nature for certain capabilities and were then adapted in order to maximise these capabilities in the use of drains and grease traps.

Do these microbes grow in my drains, and how do they survive in the environment?

We carry out an initial “seeding” of the drain or grease trap in order to introduce the microbes into the system. These microbes will attach themselves in large numbers to the surfaces of the pipe and trap, as well as any grease deposits. They consume grease and organics, converting them into carbon dioxide, water, and more bacteria.

The microbes which adhere to surfaces will continue to grow and thrive in the grease trap. They are protected from short-term exposure to high temperatures (such as when the dishwasher discharges), pH swings, and  chemical toxicity (such as when cleaning or sanitising chemicals are discharged).

Can the bacteria make me sick?

Do not worry, the product is extremely safe. We have conducted studies to make sure that the bacteria strains in our products are not hazardous either to people or pets. These studies include testing on inhalation, ingestion and skin contact. Common antibiotics will kill all of the bacteria in the product.

Our biological products are used in applications where microbes can survive. Every niche in our environment that can support the growth of microbes has already established a population of “naturally occurring” strains. We use bio-products in these niches when we want to change the conditions (for example, when we want to reduce grease).

As bio-products are seeded into the environment, they need to grow and establish their place in that pre-existing population. They work with the naturally occurring strains, often breaking down larger, more complex molecules into smaller units that actually feed many of the native strains.

Does the grease trap treatment cause the grease to be transferred downstream?

Any transference of the grease downstream would defeat the purpose of the grease trap, as grease accumulation would occur in the receiving collection systems. Numerous authorities and municipalities have raised this concern.

We have tested this potential in laboratory microcosms to verify that when grease traps are treated as recommended, we can safely conclude that absolutely no net transfer of grease from the grease trap will occur.

What happens to the microbes which are 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 continue to provide benefits by degrading organics wherever they travel in the waste collection system.

What maintenance will I have to continue to do?

Although the frequency of emptying the grease trap will be greatly reduced, the trap will of course still need to be emptied. In particular, if the water that flows through the trap contains any non-organic material (such as soil), which is not biodegradable, or large food particles, which take a long time for the microbes to digest, the trap will need to be emptied.

How can I tell if it is working?

After 4-6 weeks from the commencement of the treatment, you will see that there will be a noticeable difference. There will be a reduction in odours emanating from the grease traps, and in addition to this, the grease accumulating in the trap will have a different appearance. Rather than a thick solid crust forming, the grease in the trap will remain looking like a liquid.

Health and Safety advice

The bacterial strains are naturally occurring. Wash hands after use. Avoid ingestion and introduction to drinking water sources or foodstuffs. Bio Green products are completely natural and not harmful to the environment.

The shelf life of the liquid is eighteen months at 20 degrees centigrade.
