Grease Traps

The GreasePak MSGD5 is a bio-enzymatic fluid designed for use with GreasePak automatic dosing systems. When dosed into the drain line by the dosing unit, active enzymes work to break down fats, oils, and grease before they accumulate and cause blockages. Each pack contains three 5Ltr containers, giving a practical bulk supply for sites running an ongoing grease management programme.

Commercial kitchen drain lines handle a significant load of cooking residues, wash-down water, and food waste throughout service. Grease accumulation is one of the most common causes of drainage problems, and the downstream effects — blocked lines, foul odours, and unplanned downtime — can disrupt both kitchen and front-of-house operations. The MSGD5 fluid is formulated to maintain biological activity within the drain system between service periods. Dosing typically occurs overnight, when water flow is low and contact time within the pipework is at its greatest, giving the enzymes the best conditions to work effectively.

Practical advantages for kitchen operators include:

• Ongoing enzymatic action reduces reliance on chemical drain treatments
• Helps suppress drain odours that can migrate into front-of-house areas
• Supports grease management compliance requirements from drainage authorities
• Bulk pack format reduces reorder frequency for busy sites
• Automated dosing keeps the process hands-off for kitchen staff

It is important to note that the MSGD5 fluid is not a standalone treatment — it requires a compatible GreasePak automatic dosing unit to operate correctly. The dosing unit governs the frequency and volume of each application, so correct configuration of that unit is essential for the fluid to perform as intended. Containers should be stored in a cool, dry location away from direct sunlight and kept sealed until connected to the dosing system.

This fluid is well suited to any commercial kitchen already operating a GreasePak dosing system, including restaurants, hotel kitchens, pub operations, care homes, and contract catering sites. For higher-volume operations or sites with particularly long or heavily loaded drain runs, it is worth reviewing dosing frequency and consumption rates to ensure the programme is correctly calibrated for the volume of grease being produced.

If you are setting up a grease management programme for the first time, or want to check that your current dosing configuration is appropriate for your kitchen's output, our team is happy to talk through the options with you.

The GreasePak Battery Operated Dosing Module is a wall-mounted, self-contained unit that automatically dispenses a bio-enzymatic solution into commercial kitchen drain lines. Its purpose is to break down fats, oils, and grease — collectively referred to as FOG — before they accumulate and cause blockages or drainage failures. The unit holds a 5-litre reservoir and runs entirely on battery power, requiring no mains electrical connection.

FOG build-up is one of the more persistent and disruptive maintenance problems in commercial kitchens. Slow or blocked drains interrupt service, generate odours, and can create compliance issues under BS EN 1825, the standard governing grease management in commercial kitchen drainage. The GreasePak module is tested to this standard and carries BBA approval, which means water authorities and environmental health inspectors generally accept it as a compliant approach to FOG management — particularly where a traditional passive grease interceptor is not installed or is not a practical option for the site.

Key operational advantages include:

• Automatic dosing maintains consistent drainage treatment without relying on staff action
• Battery operation removes the need for a mains supply close to the installation point
• Bio-enzymatic action continues working between service periods to break down residual FOG
• Helps reduce drain odours in kitchen and front-of-house areas
• BBA approved and tested to BS EN 1825 for compliance confidence

Installation is straightforward — the unit mounts to a wall and doses directly into the drain line. The battery-powered design offers useful flexibility in positioning, particularly in areas where running a cable would be awkward. It is worth checking with your local water authority or environmental health officer whether a dosing unit alone satisfies your specific compliance obligations, as requirements can vary depending on site type and waste volumes produced.

This unit is well suited to cafés, pub kitchens, restaurant prep areas, and similar smaller to medium-volume operations where a full grease interceptor is not in place. For higher-output sites producing significant volumes of FOG waste, a higher-capacity solution would be worth considering.

If you are unsure whether this unit is the right approach for your site's drainage compliance, we are happy to talk through the options with you.

The Mechline BioCeptor is a combined FOG (Fats, Oils and Grease) interception and biological treatment system designed to prevent grease from entering the drainage network downstream of commercial kitchen equipment. It works in two stages: a physical FOG Intercept and Treatment (F.I.T) unit captures grease before it exits the kitchen drain, while a paired GreasePak bio-fluid dosing module introduces active biological fluid on a timed cycle to break down retained FOG within the unit. The result is a system that both traps and degrades grease rather than simply holding it for removal.

In operational terms, the BioCeptor is well suited to busy commercial kitchens where grease output from cooking lines, fryers, and prep areas creates a persistent blockage risk. The biological treatment process means that FOG accumulation within the unit is continuously degraded between maintenance visits, which in practice reduces the frequency of servicing compared with a traditional passive grease trap. Mechline report an average FOG capture efficiency of 95.6%, which is meaningful in environments where compliance with water company requirements is a factor in site management.

Key operational advantages include:

• Continuous biological degradation reduces FOG accumulation between service visits
• Flow control technology keeps the unit compact relative to a conventional interceptor
• Removable baffles and quick-disconnect fittings simplify routine cleaning
• Rounded internal profile with no sharp corners limits organic waste build-up
• Adjustable levelling feet allow installation on uneven kitchen floors

There are several practical points to be aware of before installation. Existing drain runs must be cleaned and pressure-washed prior to fitting — installing the system into partially blocked drains can dislodge accumulated grease and cause downstream blockages. The dosing point should be positioned at least two metres from high-heat discharge sources such as combination ovens or commercial dishwashers, and away from concentrated chemical discharge. Food waste disposers must not be connected to the unit. Dishwasher connections are generally acceptable, though some water companies advise against this — it is worth confirming with your local authority before specifying the installation. Ongoing maintenance must be carried out by a certified grease trap and drain service company; this is not a fit-and-forget system, and a maintenance contract should be factored into the total cost of ownership.

The BioCeptor is best suited to small and medium-sized commercial kitchens — restaurants, cafés, pub kitchens, and similar operations — where a compact, floor-standing FOG management solution is required and where drain compliance is either mandated by the water company or being addressed proactively. For sites with multiple grease risk areas, more than one unit may be needed. Higher-volume operations or sites with very high grease loads may warrant a larger-capacity solution.

If you are unsure whether the BioCeptor is the right specification for your site, or if you need guidance on positioning, dosing configuration, or compliance requirements, the team is happy to talk it through before you commit.
