Industrial Sectors

The sectors with foam problems are very diverse, since they are linked to processes of generation and treatment of waste water in physical-chemical and biological systems and also to water circuits such as refrigeration circuits and evaporative condensers.

These products are used in any process involving foam problems such as treated water, homogenization tank with agitation or aeration, biological reactors, control manholes and collectors, distillation and vacuum systems and papermaking. The selection of each chemical will depend on the surfactants present in the water, the engineering and the water quality  required.

SERVYECO, has products authorized by the FDA (US Food and Drug Administration), suitable for the foam control in food industry. Products can be put in direct and indirect contact with food, to avoid the formation of foams during their handling.

 

Benefits

The application of anti-foam products has two different functions, on the one hand, avoiding damages of mechanical elements of the installation and on the other, improving the performance in some processes such as wastewater biological treatment.

Our products have antifoam properties because they prevent foam formation and defoamers properties because they eliminate the foam already formed. ADIFOAM Series products contain molecules that combined with those molecules in the bubble walls cause its rupture and, thus, foam formed is eliminated.

1. Dosage: the use of pure product is recommended but could be dosed diluted in water over 5% concentration. Automated equipment is used to the diluted preparation but must be dosed in some hours. If the product has remained at rest for a long time, stirring is required because a fully reversible phase separation should be possible. However, it does not affect in any way the effectiveness of the diluted product. It is recommended to dose before the area with foaming problems, but it depends on each individual case. If it is also dosed in previously selected points of the facility, foam formation can be avoided as well. Dosing can be done manually at shock doses or by metering pumps, there is also the possibility of automating the use of these products with continuous foam control equipment.

2. Control: the effectiveness of these products has been demonstrated when foam formed disappears and its subsequent formation is avoided.

3. Technical: the ADIFOAM Series avoids the foaming problems eliminating formed foam and avoiding their subsequent reappearance. Some of these products contain no mineral oils, EBS or silicone oil so they are highly biodegradable and, therefore, very suitable for biological liquors. In some of the products the stabilizing materials of the emulsion facilitate the proper distribution and mixture of the product in high volume systems. Finally, within the ADIFOAM series there are some products containing a high concentration of active material so its effectiveness as defoaming is very high. Water with foam has inferior quality, because foam drags solids and complicates facilities.

4. Economic: due to foam formation, facilities sometimes are not able to manage the water flow that they were design for, so avoiding foams the proper operation of facilities is ensured, optimizing processes with the subsequent economic benefit. ADIFOAM Series are very concentrated antifoams. Because of that, the cost of products in the processes and costs of packaging and shipping are optimized.
