Abstract
An apparatus for inhibiting formation of calcium based crystal, in which formation of calcium based crystals is inhibited by adding an optimal amount of magnesium to raw water having a high concentration of calcium ions and a high variation in calcium ion concentration and an apparatus for water treatment using the same.
Claims16
An apparatus for water treatment to inhibit formation of calcium based crystal, comprising:
- a raw water tank operatively connected to a pretreatment tank to store seawater or wastewater containing a high concentration of calcium ions (Ca2+) as raw water and to supply the raw water to the pretreatment tank;
- a magnesium supplying device operatively connected to the pretreatment tank to supply magnesium to the pretreatment tank, wherein the magnesium induces a reaction for inhibiting formation of calcium based crystals in the raw water;
- and
- a calcium concentration measuring device that measures a concentration of calcium included in the raw water.
