Two Sources of body water gain
- internal production : Water produced from the oxidation of organic nutrients
- ingestion : water ingested in liquids and foods
Four sites that lose water
- skin, respiratory air ways, gastrointestinal tract, and urinary tract
- Menstrual flow (in women)
The body gains sodium and chloride by ingestion and loses them via the skin (in sweat

Desalting Plant
Based on Knowledge & technology for 30 years in water plant business, DHIC can make & provide the whole process of water desalting
-DHIC has manufacturing facilities not only in Korea, but in other countries. So it can guarantee it’s quality & has cost advantages.
Water Treatment & Operation
-Comparing with plant business, there were small number of orders & la
2.3 Methods used for restoration
Firstly, a water purification system using gravel contact oxidation process was installed to clean the water. The system located in Young-dong 2 gyo was the first to utilize the gravel contact oxidation process in Korea. It uses a media like gravel and artificially maximize the natural purification process like precipitation, absorption and decomposition by
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic

What Did Doosan Develop?
(MSF) Multi-Stage Flash Distillation: Seawater Is Heated And Evaporated,
After Which The Steam Is Condensed to Produce Desalinated Water.
What Is The Differentiation?
The Improvement of Speed and Quality
RO (Reverse Osmosis Membrane)
• A Process That Produces Water by Passing Fine Semi-Permeable Membranes.
• Doosa
water to supply their troops.
In 1949, UCLA first investigated desalination of seawater using semipermeable membranes. Researchers from both UCLA and the University of Florida successfully produced fresh water from seawater in the mid-1950s.
MED is a distillation process often used for sea water desalination
MED consists of multiple stages or "effects“. In each stage the feed w
water harvested and dry berries.
About this case, we went through a procedure to get the best solution regarding adding new dryers and converting bins. Moreover, we discussed our own creative solutions considering the trend of increasing water harvested berries.
2. In the current flow of the process, identify the bottleneck area(s). What are the causes? What recommendations, both short-term
processing up to 1500 bbls.) and then go to the dechaffing units. In all, wet berries would be processed through dryer-included system and dry berries would be processed through other machines which frequently made both berries process at the same time through the system.
IV. Milling – Quality Grading
After the berries were destoned, dechaffed and dried they were sent to one of the thr
