Water treatment and reuse

The treatment and reuse of water has now become a top priority worldwide. In many countries, water scarcity is so great and natural sources so depleted or polluted that it is no longer possible to do it without water treatment systems. For environmental reasons alone, water recycling is now absolutely essential for new construction as well as retrofit and even municipal projects worldwide.

Our water sources include rainwater or surface water, well water, effluent water from small wastewater treatment plants or greywater. Depending on the degree of contamination and treatment technology, different water qualities can be achieved. It can be used to irrigate plants and be fed into the household as process or drinking water. We specialize in decentralized and semi-decentralized systems for all climatic conditions. For over 25 years and in well over 30,000 systems, our customers are now recycling water worldwide, saving several million m³ of water annually. We develop, produce and supply a huge range of products from simple rainwater harvesting for the garden to complex treatment systems for greywater or potable water supply. The systems are used at:

  • Domestic houses
  • Apartment houses
  • Hotels
  • Office buildings
  • Production plants
  • Public buildings
  • Schools
  • Quarters

With our systems, it is usually possible to save over 50%, and in some cases even up to 100%, of the original water consumption and thus the water costs. Due to the strongly rising prices and low interest rates, many systems are now even so profitable that an investment pays for itself within a few years. Operator models are possible for larger systems.

Pre-assembled complete systems

Our complete systems with AQUALOOP ultrafiltration membranes as well as biological and chemical purification offer the best technologies for producing reusable process water in the smallest of spaces. We offer our systems in nine different sizes in order to be able to present a suitable solution for every commonly required treatment volume. Find out more about the technology and design of our complete systems, which are suitable for recycling grey water and wastewater from small wastewater treatment plants.
