Enhancement of drinkable water quality standards
- Enhanced allowable criterion of arsenic, the group 1 carcinogen in drinking water : down from 0.05㎎/L to 0.01㎎/L
- Complete solution to arsenic (As) → 99.9% removal of As with the absorption technology supporting backwash
Properties s and distribution of arsenic
- Existence type : Natural arsenic is an inorganic compound. It has two types (trivalent arsenic and pentavalent arsenic).
- Properties : trivalent arsenic with neutral ion type is highly movable and strongly toxic, and hard to be removed.
- Risk : Long-term drinking may cause a cancer and destroy tissues. Chronic intoxication may cause skin cancer and damage liver muscles and kidneys.
Properties and distribution of manganese
- Existence type : Manganese weights about 1000ppm (about 0.1%) in earth’s crust so that it is the 12th abundant element.
- Properties : Manganese as silver metal is firm, but easy to be broken.
- Risk : Manganese (Mn) accumulates in livers and the brain, causing poor development and subfertility. Manganese intoxication symptoms are drowsiness, fatigue, mental instability, and even paralysis.
Turbidity
- Definition : Turbidity is a water quality index indicating suspended solids in water.
The standard for drinking water quality is 1 NTU or less.
(The water quality standard can be different country by country)
- Function : Life of filter is long due to automatic back-washing system, Our product does not need electricity.
Electric valve can be operated by solar power.
