Fields of application
Due to its wide working range on the pH-scale GREIMIN AW-0 is suitable for defoaming of the most different waste waters and circulating process waters.
GREIMIN AW-0 is able to decrease foams that arise during processing of vegetable or animal substances or to prevent their development.
- Defoaming of waste waters in biological and mechanical sewage plants The product is to a large extent independent of the kind of the waste waters to defoam and does not show with normal dosage any negative influence on the biological life in the sewage plant.
- Defoaming of waste waters in sugar processing in the external area
- Defoaming in paper processing (mass, size press, waste water)
- Highly effective antifoaming agent with good long-term effect
The product can form a turbidity or sediment at longer storage, in particular with lower temperatures. This however does influence neither the effectiveness nor the dosing-ability. GREIMIN AW-0 is not frost-sensitive. The product can be brought into the original state at any time by stirring, pumping or slight warming.
GREIMIN AW-0 is storable in closed delivered packagings under normal temperature conditions (from +5°C to +30°C) at least a year.
GREIMIN AW-0 is only little emulsifiable and should be applied in the delivered form therefore.
Usually the product is used in a concentration of 0.01 to 0.05%. Suitability and dosage are to be determined through own practice tests on site in each case.
In order to reach a good distribution and small proportioning-amounts, it is recommended to add GREIMIN AW-0 at a place where the liquid is turbulent.
Please do not add the assessed amount of the defoamer at the same time. Fundamentally wait a certain time after addition of a small quantity until a good distribution with the watery liquid occurred. Judge the achieved effect only then and add a further amount if necessary.
