Waste treatment

Sustainability and environmental awareness, increased efficiency, purity and cleanliness requirements

Increasing demands in process water treatment, international standards or regional laws and regulations are some of the challenges that municipal and industrial water, drinking water, sewage and sludge treatment facilities must increasingly face.
Municipal or industrial companies are faced with the challenges of finding cost-efficient solutions with simultaneously increasing demands for wastewater treatment – whether it is detoxification, draining and drying of sewage sludge, membrane filter presses or belt drying and drainage systems.

The average Dry Matter Content increasing is about 2-3% points

In some cases we assisted at a reducing of the flocculant injection of 3-5% points

Dimensional stability (no folds)

No backing cloth or nopps/edge reinforcement needed anymore

Great dewatering and cake release


According to the resonance, we had from many WWT Plants, where hundreds of Barrel Neck Cloths are installed, we`re able to define following points of excellence, which makes our WWT Plant Qualities to the best performing products


Dopetac sulfo

When we launched dopetac sulfo 100® on the German market in 2009, we had plant operators saying to us: “Desulfuring? Don’t need to. My engine can cope”. But today anyone who operates a biogas plant knows only too well that desulfuring is absolutely vital. Doesn’t matter what form the gas is used in, you’ve got to get rid of the sulfur.

Once the first plants had started using dopetac sulfo 100® in 2009, word spread quickly about the advantages of the product. Since then, numerous plants have started using dopetac sulfo 100®. Together with our distributors, we’ve supplied more than 1500 biogas plants throughout Germany. In addition to this, dopetac sulfo 100 has already been used with great success in more than 30 countries around the world.
