Year Founded:

For over 25 years, the name VTS Verfahrenstechnik Schweitzer GmbH has been synonymous with innovative, economical, and environmentally friendly solutions and products in the areas of machine and system building.

Our qualified team has many years of experience and is a competent partner for municipal and industrial operators in the areas of:

  • Sewage sludge treatment
  • Municipal wastewater
  • Industrial wastewater
  • Stormwater
  • Process water


The company was founded on April 12, 1984, by Mr. Hans Jürgen Schweitzer at the Wehrheim location in the Taunus. In the early years, VTS GmbH dealt with the sale of grinders, the procedural layout and planning, coordination, implementation monitoring, and the commissioning of turnkey sludge conveyors, precipitating agent systems, and lime conditioning systems. After just 2 years, the office area was expanded and a move was made to a new location within Wehrheim.

First large order in 1994

VTS implemented a sewage sludge conveyor and loading system for the city of Zurich, with a sales volume of 1.3 million CHF. This system, which is unique to date, was the basis for a breakthrough to additional large-scale projects. Requests for installation, commissioning, and on site service increased steadily. In 1999, the installation and service department was set up.

New location

In order to be able to expand the production and office area, the company decided on a new location in Neu-Anspach, with the logistical advantage of a location in the heart of the High Taunus district, with good connections to the economic centres of the Rhein-Main area.

Regional offices

VTS GmbH is currently represented by six regional offices in Germany, Switzerland, and Bulgaria. Regional customer service agents are available for national and international areas.


The international market for water treatment places high demand on performance and innovative strength. As a modern, globally active company, VTS now provides its products and expertise internationally.

Customer-specific solutions

Whether individual components or complete systems, VTS provides customer-specific solutions with market-oriented products of the highest quality. All process steps in water and wastewater treatment are continuously further developed and mutually matched to each other. We continue to build on this, supported by service in close customer proximity.

Generation change

In December 2013 the shareholders have implemented the generation change.
Nadja Wendt and Sven Eckert have joined the company as new partners.
Doris Schweitzer herself retreats, but will be remaining active in the company until
end of 2014.
