Bombora Coffee + Water Supplies on finding water filtration solutions with BRITA

Cameron McDonald, Business Development Manager of Bombora Coffee + Water Supplies, explains how BRITA’s range of filters can handle and block even the toughest water conditions.

In March, torrential rains hit communities on Australia’s east coast, leading to severe flooding, mass evacuations of towns and thousands of damaged homes.

After an already wet summer with above-average rainfall, watersheds that are saturated and close to capacity can no longer cope.

The intensity of the flood waters caused significant erosion of the earth, sand and clay. As a result, local water agencies estimate that raw water turbidity or cloudiness in flood-affected regions has increased at least 100 times above acceptable levels.

Turbidity is caused by solid particles in a water source, which can include soil, sand as well as clay. These particles can cause significant damage to municipal water that water authorities distribute to communities.

This particularly affects municipal water sources that rely on large-scale sand filters, which can clog under the sheer volume of contaminants, or ultraviolet disinfection systems. This requires that the turbidity of the water be less than one NTU (nephelometric turbidity units), a water containing one milligram of finely divided silica per litre. This is how the transfer of disinfectant light can reach and neutralize bacterial coliforms.

So what does this mean for local small businesses, including cafes? There is a good chance that the incoming water supply has experienced sediment and particle ingress.

The key here is to fix this problem before putting your machine back into service, including unplugging the machine’s supply line and running water through a bucket until it is particle free. .

The next crucial step is to change the water filter, as any contamination in the line will also be trapped in the water filter.

Fortunately, this is where BRITA water filters can shine. Its filters are designed to mechanically remove, absorb and exchange the three most common contaminants found in Australia: chlorine, particulates and of course scale.

Filters are designed to mechanically block or absorb incoming contaminants including sediment, chlorine, scale and bacteria.

When a filter is not in use, these contaminants can begin to make the filter look like a stagnant pond inside. They can also affect the structure and overall integrity of the filter, which can lead to the filter spilling contaminants into a coffee machine.

It is for this reason that a filter change should be part of the recommissioning process of any coffee machine or water dispensing device.

When a coffee machine is left standing for a period of time, contaminants tend to settle and form a barrier in the solenoids, flow meters, group heads and boilers. Recommissioning a machine is best done by a qualified technician to ensure that the correct steps in the process are followed. However, during this process, water filters are neglected.

When it comes to the perfect time to change a water filter, most cafes and service technicians work outside of the usage time, such as three, six, or 12 month intervals.

This method potentially risks feeding your machine through a filter with depleted media, allowing harmful scale and gypsum to clog solenoids and destroy boilers.

The best way to ensure your machine is protected is to change the filter according to the capacity of the machine. This figure can be measured by installing an in-line flow meter or by using a simple calculation as shown in the breakout box.

BRITA’s 4-in-1 media composition will protect your machine from critical contaminants that can cause expensive components to expire prematurely.

At Bombora we work with BRITA for our water filtration needs and are committed to providing education on the importance of water quality and how it can affect the taste profile of coffee. COVID-19 has made it difficult to facilitate regular on-site training. However, our team regularly produces articles on water testing, performance, benefits of use and practical water filtration advice, which can be found on our website.

To ensure our customers always receive top quality water, we stock the number one brand of filters in Australia. This ensures that we have a wide range of filtration products to choose from when providing solutions for our customers’ applications.

We also offer free in-house water testing to ensure we fully understand each customer’s unique application requirements and provide the right solution, which ultimately results in quality water.

The Purity C range is a staple of Bombora’s product offering. It ensures optimum water quality for every coffee machine application in the Australian market.

Its versatile quick-change head allows anyone to easily swap filters between the Purity C Finest and Quell offerings, depending on the machine’s boiler types. This eliminates the need for a technician to change your filter and provides a cost effective solution. Namely, we recommend the Quell range of filters for copper boilers and the best filter offers for stainless steel boilers that require a PH buffer to help prevent low PH corrosion.

BRITA continues to be one of the leading manufacturers of softening-based water filtration solutions for roasters or cafe owners. Bombora has shared a working partnership with BRITA since 2008.

We believe that a good business relationship requires trust, respect, inclusion and open communication. All of these attributes exist in our working relationship with BRITA, and this is the main reason why they are considered a valuable partner to us.

In addition to being a great company to do business with, rest assured that their filters provide the best solution for all water qualities and conditions nationwide, even in the most extreme situations such as flooding.

Our hearts go out to affected businesses in the North. We wish them good luck on their road to recovery.

Cameron’s recommendation for changing a water filter:

  • Base coffee on 40 kilograms per week.
  • Base the coffee on Sydney Underground with hardness levels of 70 parts per million (ppm)
  • The assumption of 10 grams of coffee per dose
  • The use of 50 ml per dose (This includes pre-rinsing)
1 dose = 10 grams of coffee.

10 doses = 100 grams of coffee x 10 = 1 kg

100 strokes per kg x 40 kg per week of use = 4000 strokes.

4000 strokes times the 50 ml of water per stroke = 200 liters.

The C150 has a capacity of 4766 at 70 ppm.

4766 divided by 100 liters = 23.83 weeks.
