INDUSTRIAL WATER TREATMENT



We are a partner of the industry in all concerns regarding water of industrial processes and we offer individual high-tech solutions for the treatment and purification of process water. 


Our plants: 
In co-operation with the customer we provide individual process concepts for process integrated measures for ameliorate the quality and quantity of water. 
The simultaneous implementation of economical and environmental objects is our first priority. 

Our plants for water treatment can be installed upstream or downsteam of the industrial manufacturing or production processes.
  


Examples for the upstream treatment are the treatment of river water to process water for the cooling circuit of a cement producer, boiler feed water treatment etc. and for downstream purifucation, mainly waste water treatment like precipitation of heavy metals of the waste water stream.   

We deliver electro-mechanical components for all kind of procedural processes. According to
this our customers come from all fields of the process industry, like

  • Refineries and petrochemical industry

  • Chemical and pharmaceutical industry

  • Paper and pulp industry

  • Steel works and coking plants

  • Food and beverage industry

  • Flaying houses

  • Textile industry and dry-cleaners  

  • Producers of dry-cleaners  

  • Producers of metallic finishing  

 

The advantages for our customers are for example: 
  • Reutilising and recycling of water, i.e. the consumption of process water is reduced 
  • Reduction and recycling of waste water streams and therefore savings regarding waste water treatment 
  • Adaption of existing plants to new environmental standards and integration of existing plant components whereby the investment costs are reduced
  • Automatisation and process optimisation of processes - also for existing plants - allow efficient water management and a reduction of the operating costs 
  • Individual solutions with the possibility for future extension of the plant 

We are a permanent partner of our custmers regarding process development, implementation and also start-up, maintenance and repair work.

We offer our customers a transparent co-operation with an international and competent partner company and we guarantee the protection of business secrets and our reliability.

Unit operations offered:


Mechanical, biologicial, chemical and thermal processes are applied in the industrial water treatment, which are combined individually to high-tech processes. 

We use following methods for the development of processes, the  so-called
UNIT OPERATIONS:

·        Neutralisation

·        Precipitation, coagulation, flotation

·        Sedimentation, decanting centrifuges, filter plants

·        Reactors for oxidation and deoxidation, catalytic reactors

·        Combustion of waste waters  

·        Absorption, distillation, extraction

·        Adsorption, coalescence separators

·        Membrane processes

·        Electrochemical processes


 

We maintain a very efficient network with technical universities and research institutes and are able to make analysis in the laboratory and computer simulation of the processes. So we can reduce risks to a minimum, because we recognise and eliminate cost-intensive sources of error at an early stage.
