P.C.S. – that’s us

It all started with a highly competent entrepreneur – Wolfgang Ewert. In 1992 he founded P.C.S. in Hamburg. The idea was to advise sewage plant operators and industrial customers on effective sludge dewatering methods and how to find a balance between economic interests and ecological foresight. The offer was well and gratefully received, and the fledgling company quickly started getting orders from all over Germany. Enquiries from America and Asia soon followed. The competence and expert knowledge of P.C.S. was in demand right from the start.

A few years later, at the beginning of 2000, we at P.C.S. had the answer to the problem of how to prevent crystallisation in water-carrying systems. The resulting  RockAway® special chemicals developed by us conquered the national and international market.

In 2004 we started to build our own plants. Our customers had a wide range of requirements ranging from industrial wastewater treatment applications to new sludge treatment procedures such as, e.g., sewage sludge hydrolysis or phosphate elimination from digested sludge.

P.C. S. constantly gained new insights, developed new products and procedures, and implemented them in practice.

Our experience and research activities are the foundation of our work. We strive to look at our customers’ problems from all angles, provide specific advice independent of manufacturers and always incorporate the latest expert knowledge into everything we do.

Today the company is managed by Bernd Kalauch, a long-term employee and partner of P.C.S. The founder of the firm continues to be in charge of newly and further developing innovative procedures and manages the firm’s chemical products and concepts.

Bernd Kalauch is supported by a team of seven highly qualified, experienced employees. Every one of them is dedicated to what they do; always excited to take on the next project no matter if it’s small or big, short-term or long-term.

  • Independent and not product-bound
  • From basic analytics, planning and concept development all the way to turnkey deliveries

Special chemicals to prevent crystallisation and flocculation


Crystallisation and deposits don’t stand a chance

As diverse as water-carrying systems may be, there is always a risk of clogged pipes that may even force the entire plant to shut down. P.C.S. has THE solution for you: RockAway®.

Reduce residual sludge volumes

The lower residual sludge volumes, the lower storage, further processing and sludge disposal costs. If you use our SECOBLEND products, you will see the results of the dewatering process improve and residual sludge volumes decline.
