Right First Time

Correct Sizing. Assured Compliance.

I.S. EN 1825 parts 1 & 2 requires all grease traps to be correctly sized prior to installation. Sizing is based on the nature and quantity of the wastewater entering the grease trap while taking into account the maximum temperature and flow rate, the density of FOG’s (fats, oils & grease) to be separated and the influence of cleaning / rising agents. Maximum flow rates of wastewater can be determined by the measurment of (1), FOG producing catering equipment that is discharging into the grease trap or (2), the number of meals being served per day and hours of operation.

Sizing

The sizing calculator below allows specfiers to quickly and easily size a grease trap in strict compliance with I.S. EN 1825 parts 1 & 2.
In step 1, choose the sizing method based on equipment or meals per day. Then input the requested information, click calculate and the formula will provide you with a product code, NS (Nominal Size) and grease trap dimensions.
Alternatively, feel free to contact us. We can assist with every stage of the process from correct sizing and specification to Irish Water approval and installation.
We are happy to discuss your requirements via phone / conference call, at your place of work or at your clients premises.

Selection & Installation Recommendations

  • Determine the correct size by using the free sizing calculator below.
  • The unit will need to be regularly emptied and cleaned so try to locate the trap within easy reach of a large service vehicle. Ensure there is sufficient head room to remove the access lids.
  • If the trap is an underground model provide load-bearing requirements e.g. pedestrian, cars, HGV’s.
  • Ensure a level 150mm concrete base.
  • The unit must be vented to the outside of the building.
  • Sewage systems, waste dispoal units, macerators, vegetable preparation areas and sluice sinks should not be connected to the grease trap.
  • Allowance should be made for the installation of a automated bacterial dosing unit. The daily treatment should carry a DCC or Irish Water permit number.

Bespoke Riser

If the existing sewer line is situated more than 350mm below ground level, a riser will be required. This ensures the volume of the grease trap is not compromised.

Irish Water Application & Approval

Installing a grease trap without Local Authority consent could result in heavy fines and costly remediation works. Prior to fabrication, we will correctly size your grease trap and make an application to Irish Water on behalf of your client. This is a free service.

Size Scale

An undersized grease trap will not separate grease correctly as hot water from appliances will simply wash liquified FOG’s through the unit where it will later cool and solidfy in pipes and drains. Sizing a grease trap correctly requires a skilful assessment of the food service establishment. Critical information such as water temperatures, flow rates, meals served per day, etc. play a significant part in determining the volume of the unit. Investing in a non-compliant or off-the-shelf grease trap can prove costly and disruptive as Irish Water Inspectors can insist on it being replaced.

Greasetraps with Pedestrian Lids

Integrated and Recessed Lids

Integrated Lids

All our indoor and outdoor below ground models are supplied with integrated pedestrian lids as standard. This means that the removable lids, when secured, are connected directly to the greasetrap (unlike the independent lid option). Load bearing-lids can accommodate pedestrian traffic, cars, or HGV’s.

Recessed Lids

Recessed lids are the ideal way to minimise the visual impact of a greasetrap in an area of high foot traffic or where a continuous tarmac, concrete, cobble-lock, tile, or timber effect needs to be achieved. Each lid is secured to the base unit with x4 threaded bolts which are located in each corner. The compression seals ensure a 100% airtight seal, so they are perfectly suited for any indoor or outdoor (underground) location.

All our indoor and outdoor below ground models can be supplied with independant lids. This allows the greasetrap to be installed below finish floor level i.e. where the existing pipework is located deep in the ground. Independent load bearing lids can accommodate pedestrian traffic, cars, or HGV’s.

Gravity Fed & Basement BIOTRAP® with Lifting Pump

Gravity-Fed BIOTRAP®

The BIOTRAP-AG range is specifically designed for above ground applications where grey water leaving the greasetrap is gravity fed into a main sewer line. Constructed from 304 stainless steel throughout, the BIOTRAP-AG is available in 13 standard sizes with variable inlet and outlet locations to suit existing on-site pipework.

BIOTRAP® with Lifting Pump

The BIOTRAP-AG range with grey water holding tank and lifting pump is designed for basement applications where grey water leaving the greasetrap needs to be pumped up to the main sewer line at ground level. The grey water holding tank is typically one third the volume of the greasetrap.

Recessed Lids to Accept Any Floor Type.

Recessed lids are the ideal way to minimise the visual impact of a greasetrap in an area of high foot traffic or where a continuous tarmac, concrete, cobble-lock, tile, or timber effect needs to be achieved. Each lid is secured to the base unit with x4 threaded bolts which are located in each corner.

Our recessed lid model will accommodate pedestrian traffic or light goods trolleys and pallet trucks. HGV and car lids are also available. The lid design ensures the unit can be thoroughly cleaned and washed down in compliance with I.S. EN 1825 parts 1 & 2.

The recessed model can be supplied with independent or integrated lids. The compression seals ensure a 100% airtight seal so they are perfectly suited for any indoor or outdoor (underground) location. As with all our BIOTRAPS, the recessed model comes with variable inlet/outlet locations.
