Potable Water

2H Water Technologies products are an indispensable part of the process to remove pollutants from water to make it fit for drinking.


We all need water to survive. Yet there are many pollutants reducing the quality of the available resources. 2H Water Technologies products are an indispensable part of many processes applied for the removal of those pollutants from the water.


The high quality standard of 2H products, their worldwide availability and their high process efficiency have been the reasons why engineers around the world rely on 2H products.


The specific know-how of our specialists obtained through decades of experience in the water business gives our customers invaluable support.


Solids Removal:

The content of sludge, sand and silts in surface water can reach several thousand milligrams per litre. Chemical precipitation and flocculation produce important amounts of solids. The most economic process to remove this pollution is parallel plate sedimentation. Multiple sedimentation planes within one tank reduce the size and cost of the tanks.


The 2H TUBEdek FS41.50 type tube settler is the ideal product for this application. It can be adapted to process design requirements by variation of inclination, length of tubes and module sizes. The lamella sedimentation process can be most efficiently applied based on the unique features of 2H TUBEdek.


2H’s on site assembly technology makes the construction of efficient plant possible in all parts of the world. The technology is easy to apply and reliable. Reference plants producing several hundred thousand cubic metres of treated water per day are operating in Uganda, Vietnam and San Salvador.


2H TUBEdek FS 41.50 features:

  • Mechanical strength simplifies installation, cleaning and maintenance
  • Advantageous hydraulic parameters achieve efficiency (Reynolds number)
  • Equidistant Channels for full sedimentation
  • Special support systems avoid impact on the process
  • Up to 15 sedimentation planes above one m² of base

V-shaped tubes improve the discharge of solids


Nitrogen Removal:

Surface water can be polluted by agricultural, industrial or municipal discharges of nitrogen (ammonia or nitrate). For the removal of these components biological processes are a valuable option – also for potable water. Nitrification and denitrification are biological processes that need carriers with surfaces to establish and maintain the biomass.


2H supplies a large variety of such carrier materials – either BCN-range for moving bed or TKP319 for structured media reactors. Reference plants with capacities treating up to 500kg/d of Ammonia in potable water are operating.


2H’s lamella separators TUBEdek comprise modules of interlocking plastic tube settlers which allows the efficient separation of solids from liquids, an essential part of the sedimentation process for potable water.
