Pros and cons of various salts on the market. What are the environmentally friendly alternatives?

How to combine different salts to get an effective treatment on e.g. hard packed snow. Which salts can be combined to get the best Pre-wet strategy. Which salt melts the most snow? Which is the fastest? A complete run through of the face diagram.

The demands differs between highways with cars and cycle paths. What are the decisive factors?

Dissolution of salt in batches or continuous saturators to create brine. Pros and cons for an investment.

Production of brine in municipal waterworks. How does today's process work? What concentration does the brine actually have in the process? Do I use the correct salt variety? Do I have problems with bacteria?

In many applications, the grain size is the most important parameter. In the case of de-icing, the grain size must be within a specified range and certainly not too fine-grained. When dissolved in water, to make brine, it is important that the grain size not to be too small or too large, then you never get the salt concentration needed for the application.

Salt is hygroscopic, i.e. it absorbs moisture. The effect of moisture depends on the grain size. Most commonly it forms lumps, loses its free-flowing property and cloggs pipes when blowing. For example in de-icing a lumpy salt may clog the spreader, making the highway untreated. This can surprise drivers and cause major accidents. The moisture analysis is performed according to ISO.

Salt contains mostly sodium chloride. However, there are always more or less contaminants in salt that will have different effects like, foaming, clogged filters or pipes etc...

A chemical analysis answers all these questions by specifying NaCl, CaSO4, MgSO4, SiO and other unwanted particles. We carry out the chemical analysis according to ISO in an accredited laboratory.

Salt has various additives depending on the application. For example, in order for salt to be free-flowing, Sodium ferrocyanide or Silica is added. Salt with iodine has potassium iodide added and Nitrite salt has different amounts of sodium nitrite. Low sodium salt contains different amounts depending on the manufacturing technique and the mixing process. The shelf life of the additives varies and the storage mode affects the remaining content. We do a review of the need and perform analyzes after that.

Salt is handled in different ways from factory to customer. In some cases, the salt may be contaminated by loaders, conveyor belts or piping systems, even birds. We take samples according to the standard for sampling and carry out bacteriological analyzes.
