Nanobubbles in Laundry

Nanobubble water can be used to complement cleaning performance on soils that are hard to remove under ordinary laundry conditions, and the degree of improvement depends on the soil and fabric type.

Honour Tech has compared the laundry performance of ordinary water and nanobubble water on various fabrics and soils, including cotton, polyester and blends. In-house comparison tests showed a tendency for larger differences in cleaning performance on hard-to-remove soils than on soils that wash out easily with ordinary water.

However, results confirmed on specific soils cannot be applied equally to all fabrics or laundry conditions. When considering adoption, it is appropriate to select frequently occurring soils and fabric types and compare removal performance under the same conditions as the existing wash program.

Once the cleaning effect of nanobubble water is confirmed, detergent use can be adjusted step by step while maintaining the target wash quality.

Laundry performance is affected by detergent type and concentration, water temperature, wash time, mechanical action and the properties of the fabric and soil. Because nanobubble water is applied to complement detergent action, eliminating or cutting detergent across the board is not recommended.

It is best to first compare cleaning results with ordinary water and nanobubble water at the existing detergent dose, then, once improvement is confirmed, lower the detergent concentration step by step while checking wash quality and residual soil. Rinse conditions and operating time can also be evaluated where needed.

In most cases, a nanobubble system can be added to the water supply while keeping existing washers and wash programs.

In facilities with a storage tank, laundry water is circulated through the nanobubble system and then supplied to the existing washers. For facilities without one, the connection method is reviewed according to peak instantaneous supply, piping pressure and whether hot water is used.

Honour Tech checks the number and capacity of washers, daily laundry volume, water supply method and current detergents and wash programs to determine the right HQN model and installation configuration. Initially, it is best to keep existing wash conditions so the effect of nanobubble water itself can be compared.

Using nanobubble water does not in itself cause fabric damage, but quality effects should be checked according to fabric type and wash conditions.

Fabric damage and deformation are affected by the washer's mechanical action, water temperature, detergents and bleaches, wash time and the material and structure of the fabric. When introducing nanobubble water, it is appropriate to evaluate cleaning performance and fabric condition together against existing wash conditions.

For premium garments and delicate fabrics in particular, quality items such as color change, shrinkage, surface damage and hand feel should be compared. Cleaning comparison tests to date cannot guarantee that every fabric will be undamaged, so testing with the items you actually handle is recommended.

In commercial laundry, economics should be evaluated by comparing cleaning quality, the potential to reduce rewashing, detergent and water use, and equipment operating costs together.

The economics of a nanobubble laundry system are evaluated by comparing cleaning quality, detergent and water use, rewashing frequency, heating energy and system operating costs as a whole.

Honour Tech recommends comparing soil removal results and key operating indicators under existing wash conditions and under nanobubble conditions. It is sensible to calculate economics after confirming whether detergent, water and rewashing can be reduced while maintaining the target wash quality.
