Cleaning

If things have gone wrong you may need to clean/descale the parts that are covered of deposits. Kemi-tech offers the type of cleaning agent that is necessary for handling your cleaning/descaling.

In case of major cleaning works it is recommended that the deposits are analysed in order for us to choose the correct product.

We have pre-mixed descaling fluids as well as concentrated powder for subsequent manual mixture. We would be happy to help you give you an estimation of the assignment/price. We would like to make it clear that all descaling assignments will be carried out without the risk of corrosion damages.

Cleaning/Anti-Scaler

Boiler
We offer to clean out sludge/deposits (e.g. magnesium hydroxide, calcium sulphate deposits) from your steam boiler, while the operation is maintained. You would normally during the cleaning period blow down a bit more than normally in order to clean out the problematic substances in that way.

Cooling
Kemi-tech offers removal of calcium carbonate, calcium sulphate, magnesium hydroxide, iron oxide, precipitated phosphates and silicates in cooling towers/condensers without the need of shut-down. The cleaning will typically be carried out during the course of 10-90 days depending on how thick the deposits are. Naturally the cleaning is carried out without the risk of corrosion damage.

Reverse osmosis-facility

In larger reverse osmosis facilities (a RO-facility) it is often not worth the effort investing in a softening facility that requires salt and maintenance. Instead it is more convenient supplying hard or lakewater directly to the RO facility. When using hard water it is absolutely necessary to add a antiscale product in the feedwater. This is used in order to prevent deposits in the membranes resulting in a reduced performance.

Recent findings have shown that in more than 50% of all cases where deposits are formed on the membrane surface are caused by biofilm deposits. Keeping this in mind all of Kemi-tec’s anti-scale products have also been designed to prevent this type of deposit. The quantity of the products to be used can be precisely measured using operational data and water analysis.
