Water Treatment

Water treatment describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water, industry, medical and many other uses. Such processes may be contrasted with small-scale water sterilization practiced by campers and other people in wilderness areas. The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use. One such use is returning water that has been used back into the natural environment without adverse ecological impact.
The processes involved in treating water for drinking purpose may be solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation.
Biological processes are employed in the treatment of wastewater and these processes may include, for example, aerated lagoons, activated sludge or slow sand filters.
Engineering, Procurement, Construction and Start up of Industrial and Sanitary water treatment units Pretreatment systems such as:

  • Clarification (Coagulation, Flocculation and Sedimentation), Design and construction of sand filters and activated carbon filters.

    Ion Exchange packages such as Anionic resins, Cationic resins, Mixed bed resins and declassifies.

  • Membrane treatment systems (Ultra filtration and Reverse Osmosis).
  • Distillation Desalination Systems such as Single Stage Distillation (SSD).
  • MED Desalination Units (Multi-Effect Desalination).
  • MSF Distillation Units (Multi-Stage Flash Distillation Units).
  • VCD Desalination Units (Vapor compression Distillation).
The Concept
the water treatment solution consists of several treatment steps, e.g. filtration, softening, and demineralization - all controlled from a central control cabinet. These units must be put together on site.
If the end-user or the contractor is uncertain if the installation can be carried out locally within the determined economic and temporal scopes, it can be an advantage to order a water treatment plant (container or frame-mounted) which is ready for use when supplied.
The solution is complete with all internal piping and wiring factory-built. The whole plant has been performance and pressure tested in our factory. This safety can be achieved with a frame-mounted plant or a container-installed plant.
With a container, you also have the advantage that the container its self is an actual building which in this way can be left out in the project. The containers can be delivered with and without insulation and can be equipped with lighting, air-conditioning, door-in-door, emergency shower, etc.
We have constructed many different custom-made plants adapted to specific demands and wishes. Below, you can see different examples of this.
We are happy to make quotations for start-up of plants and training of the operating crew.

Complete water treatment plant in a 20 feet container.

  • The solution consists of dosing, carbon filtration, softening, and demineralization through a reverse osmosis plant.
  • 40 feet container with water treatment consisting of oxidation and filtration in a pressure filter plant type TFB 20. The plant has a capacity of 90 m³/h.
  • 64 m³/h dematerialized water produced in a reverse osmosis plant. A dosing plant is also installed in the container.
  • EDI plant with a capacity of 60 m³/h totally dematerialized water with a very low conductivity and silica acid content for producing boiler water for high pressure steam turbine.

    The pipe system for the treated water is made in PP (Polypropylene) connected by welding and each takes app. 15-20 minutes to make. In total, 570 welding have been made for this plant. Each EDI cell is fitted with own test cock.
