What we do

Terraheim will proceed to find the convergence point of appropriate technology.
The requirements for the development and application of technology will vary depending on the region, country, and culture.
We would like to be a true “small but strong” enterprise that does not hesitate to go to the world through technological development that can cope with such different acceptance.

Stability

HDPE TerraSAN® pipe can prevent the formation of biofilms (up to the minimal level) and thus increase the biological stability of tap water.

Efficiency

TerraSAN® can be widely applied to prevent biofouling in many kinds of fluid-transporting pipes.

Safety

TerraSAN® pipe have confirmed to meet the OECD regulation and pass the Korean Standard Elution Test.
Before taking up the main subject

Water

We solve the problem of cleanliness of the water that should be preempted for drinking of tap water.
About water
▶ Water
* Silent Planet Earth. (water accounted for 71% of the Earth, of which 97.2% were seas)
* The special planets of the solar system - the essential components of surface life.
* Water is too close when storing water.
* Birth growth that keeps the nature and cycle of life.
* More than 65% of our bodies are life-sustaining and multiplying. Metabolism essential for metabolism.
* Water is essential for photosynthesis and breathing.

What is the problem?

Problems in Water Distribution Network System
▶ Forming biofilm inside
A biofilm is a surface deposit of bacteria, other microorganisms, and organic and inorganic materials that accumulate within a slime layer. Biofilms can form on solid and liquid surfaces when nutrients and water are present.
Public health concerns related to biofilms in distribution system include the documented presence of primary and opportunistic bacteria, viruses, protozoa, and fungi.
The multiplication of micro-organisms in biofilms along the distribution systems results in : The deterioration of the water quality in the distribution systems
1. The development of odor or color
2. The acceleration of corrosion within the pipelines (bio-corrosion process)
3. Increased disinfectant demand
- Water Pipe Suppressing the Forming of Biofilm is Required
- Clean Water Pipe is the First Priority to make Tap-Water Drinkable.
▶ A Biofilm is ......
A biofilm is a surface deposit of bacteria, other microorganisms, and organic and inorganic materials that accumulate within a slime layer. Biofilms can form on solid and liquid surfaces when nutrients and water are present.
Much like plaque that forms on teeth, biofilms form inside the distribution systems of drinking water and can sometimes cause a number of problems.

Clean surface
Conditioning
Film of dissolved organic matter
PhaseⅠ
Primary microbial colonization
PhaseⅡ
Irreversible
Microbial attachment
Mature biofilm
Assemblage of surface-associated microbial cells that are frequently embedded in a matrix of EPS (Extracellular Polymeric Substances)
Complex and heterogeneous structure (200 ~ 300 µm thickness)
▶ Problems Associated with Biofilms in water pipe
Just as all teeth have some plaque, all distribution systems come to retain some biofilm, in both cases, problems can occur when they are not controlled.
Public health concerns related to biofilms in distribution system include the documented presence of primary and opportunistic bacteria, viruses, protozoa, and fungi.
