The present invention relates to a process for reduction of the presence of microorganisms and/or decomposition of organic micropollutants in water using an energy source and an additive characterized in that the energy source is UV radiation and the additive comprises performic acid.

Water treatment

The invention relates to a method for treating wood in order to improve its properties of use and storage, and to thus obtained treated wood product. In the method the wood to be treated is contacted with a treatment composition comprising monoester, diester or triester or a mixture thereof formed by a water soluble C-Calcohol and formic acid as an equilibrium solution. In addition, the invention relates to specific treatment solution compositions.

Biocidal composition for wood, method for wood treatment, and wood produced thereby

In a method for preparing formic acid, methyl formate is prepared with methanol as a reactant. In the method, methyl formate obtained from methanol in a reaction is fed through an ion exchange bed, in which the hydrolysis into formic acid and methanol and the separation of formic acid from methanol take place simultaneously by means of the catalytic and adsorbent properties of a solid in exchange material in the ion exchange bed
