Manganese sand filters water

What are heavy metals?

The rapid development of the industry causes the environment to be heavily polluted, especially the water environment is seriously affected by heavy metal contamination.

Untreated wastewater discharged directly into rivers and lakes contains many heavy metals that easily leach into water but have extremely low self-decomposition ability such as mercury (Hg), arsenic (As), copper (Cu), zinc (Zn). ), lead (Pb), chromium (Cr), nickel (Ni). 

Harmful effects of water contaminated with heavy metals.

When water sources are contaminated with heavy metals, they will bring unpredictable consequences to the living environment as well as human health.

Water contaminated with heavy metals directly affects the growth and development of aquatic animals, shrimp, fish, and plankton, although they will die en masse or lose their ability to reproduce and fight against diseases. with harsh changes in living environment. 

Using this water source for irrigation will reduce crop productivity. Using water contaminated with heavy metals for a long time will seep deep into the ground, causing the soil to lose its fertility.

Water contaminated with heavy metals when used can be easily recognized by its characteristic foul, fishy odor along with yellow water color and floating scum. Kitchen appliances and water equipment become unsightly and form plaque, reducing the life of the object and increasing the electricity consumption of electrical appliances such as electric kettles, water heaters, and washing machines. ....

In particular, water contaminated with heavy metals directly affects human health, causing countless dangerous diseases such as brain damage, muscle contractions, fetal malformations, cancer...

Manganese sand is a well-known material with the ability to treat heavy metals effectively.

What is manganese sand? The role of Manganese sand in the water filtration process

Manganese sand is a type of ore available in nature, mined by open pit method or mined in mines, using permanent magnets to create manganese sand, crushed or coarse depending on usage needs. . 

Characteristics of manganese sand.

• Manganese sand contains specific chemical ingredients such as Manganese(4) dioxide (Mn(OH)4), potassiumpemangannat (KmnO4), in addition to some other substances such as Fe, MnO2, SiO2... 
• Manganese sand is solid, granular, and has a light density.
• The brown or black layer covering the outside functions to increase exposure and oxidation potential.

Advantages of manganese sand

• Abundant in nature, easy to exploit, easy to process at low cost.
• When reused, just rinse with water, no need for any cleaning chemicals.
• Manganese sand is a "benign" material that can easily be combined with many other materials to increase filtration efficiency without worrying about any reverse chemical reactions occurring.

The role of manganese sand in the treatment of water contaminated with heavy metals.

• Manganese sand also has the ability to filter out heavy metals in water such as arsenic, iron, manganese, copper, lead, zinc, and eliminate fishy odors.
• Very good ability to remove chlorine, phosphate, nitrate, sodium, ammonium from water.
• Waste oil is one of the raw materials containing a lot of lead, manganese sand has the ability to absorb oil into sand grains, treating excess lead in oil.
• Manganese sand contributes to balancing the pH in water contaminated with heavy metals.

Where is a reputable place to buy manganese sand?

Currently, there are many companies providing manganese sand with an average price from 6,000 VND to 12,000 VND/kg. However, there are many types of manganese sand on the market, consumers need to choose a unit that also supplies good quality sand.

E &C Vietnam Environmental Technology Services Joint Stock Company specializes in providing manganese sand produced directly domestically at low prices and high quality, contributing to creating clean water sources for living and production.
