DOS 1 - caustic soda additive

DOS - 1 contains complexed reagents, emulsifiers, anti-foaming agents, non-ionic surfactants.

The product:

* neutralises water hardness,

* prevents the formation of scale deposits,

* improves the cleaning properties of lye,

* improves the effectiveness of lye leaching,

* prevents the formation of sediments on tank walls.

DOS - 1 contains biodegradable surfactants and improves cleaning effectiveness. The preparation was design for use in closed CIP circulation systems.

The product allows to limit soda use by about 10%, decrease the use of water in the rinsing process and the frequency of needing to acid wash the installation.

Scope of application

The preparation can be used to clean all typical surfaces normally cleaned using lye solutions. It’s used as an additive in working caustic soda solutions, in concentrations of between 0.1 and 0.25%, depending on water hardness. The additive may be replenished in cleaning tanks proportionally to the amount of lye added.

When adding a 0.1% DOS-1 solution to 100kg of a working NaOH solution, add 0.1kg DOS -1 to NaOH with a concentration of 1%, 2% or 3%.

DOS-1 may be added to liquid sodium hydroxide (with a concentration of approx. 50%).
