Preparation of working solutions

Methodology and conditions for preparing working solutions

Working solutions of “DEFENS D2” are prepared in marked containers made of any materials except galvanized iron, by dissolving in water while mixing for 1-2 minutes. Drinking water is used to prepare working solutions of the product. When preparing working solutions of 0.5-2.5% concentration, it is advisable to first prepare a suspension of the product in a small amount of water and then bring it to the calculated volume with water. Hot water at a temperature of (60±5) °C may be used to prepare 0.5-2.5% solutions of the product to accelerate its dissolution in water.
