These include in particular dyes and fragrances with which the own color or the inherent smell of the mixtures is masked. Other solvents can Although they are always added, they are generally not required.
- the surfactant component B usually behaves like a Newtonian liquid, i.e. their viscosity is independent of the shear forces. Such agents are therefore easy to promote and dose, with their Viscosity changes relatively little depending on the temperature. she are repeated even after several months of storage in a climate cabinet changing temperatures between minus 10 ° C and plus 40 ° C they do not tend to segregate.
- the concentrates are at least up to 0 ° C a liquid consistency. Between minus 10 ° C and 0 ° C they can be in liquid or solid form. Even those in solid form at these temperatures Concentrates again give clear and homogeneous when thawed Liquids. These properties make them particularly suitable for one fully automatic dosing in commercial laundries.

It is also possible to use the wastewater as well to pass pre-cleaned wastewater through a membrane several times. The number of successively arranged membranes are usually dependent on determines the amount of water to be processed per unit of time and depends on the Size of the membrane.
- the wastewater can be passed through the membranes for as long the membranes are circulated until the water has sufficient Purity. To the cost of the overall washing process, especially the Lowering the need for water can do so through the membranes purified water depending on the requirements for the prewash and depending of the quality of the membrane also for the clear wash and / or for the first or second rinsing bath can be used.
