TASK proves time and again that we take all constructions and placements very seriously by meeting the required standards and obtaining the necessary certificates. We are therefore the right partner for carrying out your installation.

Coagulation and flocculation

This technique is used for contaminants that do not settle on their own, e.g., colloidal particles. The addition of coagulants causes the destabilization of colloidal particles. This causes flocculation of the particles, which can be further enhanced by adding flocculants. The floccules can then be separated in the next step. This can be done, for example, in a flotation.

Flotation

Flotation is a technique that provides separation of suspended solids, oils, greases and other undissolved particles. This technique can be used as pretreatment for further treatment or as the sole treatment of water. The most commonly used flotation technique is Dissolved Air Flotation (DAF), in which air is dissolved under pressure in the water to be treated. The very fine bubbles thus formed bind with the floc particles in the water. The flake particles rise to the water surface and form a floating layer. The floating layer is scraped off and collected in a container. The sludge can then be further thickened and/or dewatered.

The great advantage of this type of installation is that it can be fully automated, making it very maintenance-friendly.

Neutralization

Essentially, one is going to neutralize wastewater (pH +- 7) to make it suitable for further degradation in a biological wastewater treatment plant or to meet discharge standards.

Neutralization is a technique used on a wide variety of wastewaters. This type of installation is quite simple. It is a fairly compact set of storage and reaction tanks with the necessary dosing and mixing equipment. Moreover, they can be fully automated and are thus maintenance-friendly.

Membrane filtration

Membranes can be very versatile in water treatment. Membranes are used for, among other things: deferrization, softening and demineralization. We also offer water recovery plants where membranes are used.

Sludge Processing

In many cases, sludge remains as a residual product after the physical-chemical water treatment process. In most plants, the sludge is removed by third parties. Therefore, it is economically important to keep the volume of sludge as small as possible. One method for dewatering sludge is the chamber filter press. The sludge is pumped under increasing pressure into a closed space or chamber. After pressing, the chambers open back up and the solid filter cakes fall out of the chambers. Optionally, the presses can be equipped with a high-pressure spray system to clean the cloths.
