Why commercial dishwashers reuse water

By reusing water, recirculating commercial dishwashers are substantially more efficient than their “fill and dump” counterpart, which – as the name suggests – dumps and refills wash water with every cycle.

Each rinse cycle in a recirculating commercial dishwasher replenishes the wash tank with fresh rinse water, which keeps water use down, speeds up the process and lowers energy and chemicals consumption.

Commercial dishwashers from Nor:disk can reuse wash tank water for 25-30 cycles, depending on how dirty the dishes are and pre-rinsing adherence. Moreover, rinse water volume is kept to an industry low, by utilizing the patented Sequential Rinse system (Water-Smart range - patent no. IT201900010245A1).

The main benefits of reusing water

Cost Savings: Reusing water decreases both water, energy, and chemicals expenses.
Environmental Sustainability: Conserves water, energy, and chemicals while minimizing wastewater discharge.
Operational Efficiency: Water reuse enables quicker cycle times and efficient high-volume dishwashing, as you can utilize already heated water and don’t have to wait for heaters.
Enhanced Reputation: Adopting water reuse practices reflects well on a business's environmental responsibility – use your smart equipment choices to boost your brand!

How do commercial dishwashers ensure cleanliness while reusing water?

“Won’t the dishes be dirty if you wash with reused wash water?”

No, for two main reasons:

Recirculating dishwashers use different kinds of filtering techniques, which keeps the wash water fresher for longer.
But also, securing hygiene and sanitization is done through a hygienical final rinse cycle using fresh water at high temperature.

The process is similar to what you would do at home when doing the dishes in your sink. Scrub and wash in one sink, reusing water to get the dishes clean, and then rinse them off in fresh water from the tap.

The Nor:disk Granule range has powerful pumps that grind food debris into smaller particles, which are then skimmed off the surface of the wash tank water. Our Water-Smart range instead utilizes a drain pump, which sucks the dirties water and debris out from the bottom of the wash tank.

Nor:disk commercial dishwashers secure hygienical wash results and comply with hygiene standards regulated in EN 17735:2022.

Is there a significant price difference between standard and water-efficient commercial dishwashers?

Water-efficient dishwashers typically come with a higher initial cost due to their advanced technology and larger pumps.

However, these machines not only offer a quicker return on investment (ROI) by rapidly offsetting the initial costs through reduced water and energy consumption, they also provide higher overall financial savings in the long term.

This combination of a faster payback period and greater cost savings makes them an excellent investment choice for commercial operations prioritizing both cost-efficiency and sustainability.

How can I choose the right water-efficient commercial dishwasher for my business?
