How does the BioCeptor work?

 

The BioCeptor works in two ways to prevent fats, oils and grease (FOGs) including starches from going down your drain where it can cause blockages when it cools and hardens.

 

Waste water from your sinks and dishwashers enter the BioCeptor F.I.T unit and when the water cools the FOGs harden and float to the top of the unit. As well as this the GreasePak dosing module delivers a daily dose of unique bio-fluid formula into the F.I.T unit which breaks down the FOGs into irreversible compounds that can easily pass through drainage. Most importantly these compounds can not reform further down in the sewerage network.

 

The FOGs that are retained in the F.I.T unit will need to be removed and disposed of by a qualified contractor but the frequency of emptying is greatly reduced.

 

 

Is the bio-fluid safe for my kitchen?

 

Yes. The bio-fluid (GP-MSGD5) contains a blend of aerobic and facultatively anaerobic bacteria which have been specially selected to break down the organic material that is found in commercial kitchen waste. Armed with a powerful battery of grease-degrading enzymes, they are all classified by the Advisory Committee on Dangerous Pathogens (ACDP) as category 1, i.e. they are of extremely low or no hazard. Mechline’s GreasePak bio-fluid dosing module is the only bioremediation system to receive BBA approval, meaning the system has been independently tested and found to be compliant with building and legislative requirements.

 

 

How does the bio-fluid work?

 

Mechline’s bio-fluid uses a blend of specially selected microorganisms that have been chosen for their ability to degrade fats, oils and grease (FOGs) in low oxygen conditions and varying pHs.

 

These bacteria produce a series of extra-cellular enzymes that break down organic matter, including lipase, which can very quickly transform fats (triglycerides) into glycerol and free fatty acids. Glycerol is very soluble in water and being a small molecule, can pass easily into the bacterial cells, where it is used either to build new cellular structures, or as a fuel to produce energy for growth.

 

The free fatty acids present more of a problem, as they are large insoluble molecules. The action of the lipase has only converted one type of large insoluble molecule (the triglycerides) into other large insoluble molecules (free fatty acids). Visually, in a drainage situation, the scale of the problem may have diminished or the characteristics of the fatty material may have changed at this point, but the problem will not yet have been fully resolved.

 

The specially selected bacteria in the bio-fluid are able to degrade these free fatty acids by a process known as ß-oxidation, in which chunks are broken off the end of the fatty acid molecule. These chunks can again be used as a building block to produce new structures, or more usually, energy. The breakdown of fatty acids is not an instantaneous process, as the physical form of the fatty acids, being large and insoluble, means that it takes some time (commonly called “residence time”) for the bacteria to “get to grips” with them. This is why the bio-fluid is dosed at 1:00am, when there is little or no water flow, allowing the bacteria time to do their work.

 

Once the fats are broken up by the lipase they cannot chemically reform back into triglycerides. The subsequent breakdown of the fatty acids through ß-oxidation ensures the “grease,” which may actually consist of a variety of insoluble materials, can pass through drainage systems without causing any problems traditionally associated with fats, oils and grease (FOGs).

 

Mechline’s biological drain maintenance system effects the “removal of grease” from drainage systems—keeping drains clear and odour-free and meeting the requirements of the Building Regulations, using an environmentally friendly and non-hazardous fluid.

 

 

Where can I install the BioCeptor in my kitchen?

 

Please refer to Chapter 4 (Location Advice) in the installation & operating manual.

 

 

I have lost the keys for my dosing module, can I get replacements?

 

Yes. The keys for all dosing modules are interchangeable. Please contact Mechline or your dealer for a replacement set.

 

 

Are there special storage or handling requirements for the bio-fluid? Does it have a shelf life?

 

Mechline’s bio-fluid is a perfectly safe class 1 fluid, and there are no special handling requirements. It should be stored in a cool, dry place away from direct sunlight and ideally at a temperature between 10°C and 30°C so the effective performance of the product is not compromised. The bio-fluid’s shelf life is a minimum of 18-months, as long as it is stored as above.

 

 

How will I know when the bio-fluid needs replacing? And where can I get replacement bio-fluid boxes?

 

The dosing module will sound a alarm buzzer once every 15 minutes when the fluid box inside your dosing module needs replacing. It will only sound during daylight hours in order to preserve battery power.

 

For more bio-fluid please contact Mechline or your dealer. Sold in master boxes of 3x 5-Litre (part number GP-MSGD5). Please have the serial number of your dosing module ready when you call. Always keep a spare box of bio-fluid in stock to avoid running out.

 

 

How long should a 5L (1.3 US gallons) bio-fluid box last?

 

On the factory setting (number 2), a 5L (1.3 US gallons) box of bio-fluid should last approximately 30 days. If the dosing module is adjusted to deliver a higher dose (number 3 or 4), the fluid will not last as long. It is recommended to keep the delivery volume at the factory setting as this delivers the correct dose for the size of the BioCeptor F.I.T unit.

 

 

I notice residual fluid in my bio-fluid box.  Is it using up all the fluid?  Have I changed the fluid too early?

 

Only change the bio-fluid box when the buzzer sounds. This ensures the most efficient use of the full 5 litres per box. The design of the bag and valve is engineered to provide good flow, using gravity, to match the dosing level set by the module.  It is very difficult to completely drain any bag of all its fluid, therefore, we slightly overfill each bag to compensate and make sure that every customer gets the full 5 litres from each bag.  Drainage wedges are also fitted to the inside of each box to ensure that a ‘V’ shape is formed under the bag whilst the bag empties to assist draining.

 

 

What procedures should be taken if the bio-fluid box leaks and/or the fluid comes into contact with skin, eyes, etc?

 

Mechline’s bio-fluid is a perfectly safe class 1 non-hazardous fluid.  No harm will come from touching it or coming into contact with the fabric of the building - merely wash off the fluid with cool, clean water.

Avoid ingestion of liquid and avoid contact with eyes.  In case of contact with skin or eyes, rinse thoroughly with clean cool water.  Should eye irritation continue, seek medical advice.  In case of ingestion, DO NOT induce vomiting.  Seek medical advice.  Refer to the safety data sheet on page 3 of the installation & operating manual.

 

 

Can I change the time when the dosing module doses the bio-fluid into the BioCeptor F.I.T unit?

 

The dosing module is factory set to dose at 1:00am, when there is little or no water flow, allowing the bacteria time to do their work. However this can be changed by removing the front cover under the module door and following the instructions on the label inside. Unscrew and pull the front cover downwards to remove. See section 5.2.21 in the installation & operating manual.

 

 

Can I change the fluid dosing level on my dosing module?

 

Yes, but the factory setting (number 2) delivers the correct dose for the size of the BioCeptor F.I.T unit. See section 5.2.21 in the installation & operating manual.

 

 

How long does the battery in the dosing module last?

 

The battery should last around 2 years. When the battery needs replacing the ‘Low Battery’ warning light will begin to flash. It will only flash between the hours of 07:00 - 20:00 when someone is likely to be around to see it, in order to preserve power. Contact Mechline or your dealer for a replacement battery pack (part number GP-BP) as soon as you see the ‘Low Battery’ light flashing.

 

 

My building drains are not connected to mains sewage. Can I use the BioCeptor with a remote aerobic or anaerobic (Septic) sewage system?

 

Generally, Mechline’s bio-fluid is helpful to these systems, and some information is provided below. For more advice, contact Mechline.

Aerobic Systems:

 

These tend to have three sections, a primary tank, an aerobic zone and a tertiary tank. The primary tank is where larger solids settle out, whereas the aerobic zone is where aerobic bacteria break down any organic solids. Aerobic conditions are maintained by the introduction of forced air or by the rotation of disks within the effluent. The tertiary tank allows for any final settlement before water is discharged.

If grease enters this system untreated it will quickly cause major overload to the primary tank, as it tends to float rather than settle out. Left unchecked this grease can then foul the aerobic zone either by coating the filter disks or blocking air gaps in the filter medium. This can result in severe system failure and all that implies. The introduction of Mechline’s bio-fluid into the effluent stream quickly breaks up the complex grease molecules into much smaller molecules and soluble compounds. This greatly reduces the problems described above and the chances of system failure.

 

Anaerobic (Septic) Systems:

These systems rely upon the action of bacteria that do not require oxygen to break down organic solids, and are less complicated as they do not require the maintenance associated with the aeration of aerobic systems. However, the down-side is that they are slower in action and are not suited to larger sites.

 

The introduction of grease into a septic system would cause many problems, not least the fact that the crust on the top of a tank must be permeable to allow the passage of the gases created by the action of the bacteria. The presence of large quantities of grease would reduce crust mobility and therefore the effectiveness of the tank.

 

As with the aerobic system, the bacteria contained in bio-fluid break down the fats and grease found in commercial waste, thus greatly reducing the chances of grease-related compounds. In addition, the facultatively anaerobic bio-fluid bacteria added to the mix reduce sludge build-up and therefore tank emptying frequency.
