At present, rapid industrialization and urbanization and population growth put increasing pressure on water resources in many territories. The water environment in many countries is increasingly polluted by wastewater, emissions and solid waste. Vietnam is facing a huge challenge in terms of water pollution, especially in industrial zones, urban centers and craft villages.
The water source used for human daily needs is mainly surface water. The areas of ponds, lakes and rivers in Vietnam are seriously polluted, people in these areas do not have enough clean water for daily use as well as for main production activities. It greatly affects the quality of life of people. When using polluted water, it will lead to the generation of many germs of disease. The most serious consequence of this situation is the increasing number of people suffering from intestinal diseases, cancer, and nerves, especially children in polluted water areas. To handle the above problems, it is necessary to have comprehensive solutions to thoroughly solve the sources of environmental pollution as well as directly treat contaminated water, air and solid waste. In which using products originated from Diatomite is one of the optimal solutions.
Diatomite for wastewater treatment is a material with the main composition of diatomite ore treated with special technology, which is fundamentally different from other synthetic wastewater treatment materials. Diatomite mainly adopts the main adsorption mechanism, so there is no chemical reaction with the substances in the initial solution.
Diatomite is considered a green product that contributes to environmental protection. Diatomite in powder or granule form, acidic pH = 6, density 0.4 – 0.5, opaque yellow or gray color depending on the active SiO2 content in the product. Diatomite has the natural properties of mineral materials, through the preliminary processing process with modern technology to create a new waste water treatment material, with breakthrough efficiency and economic value. with other traditional processing methods. Diatomite not only treat non-polar solutes, but they are also particularly effective for wastewater containing heavy metals, toxins, radioactive substances thanks to the special surface functional groups and pore structure. in Diatomtie. All industries can use Diatomite to treat industrial wastewater, especially some industries such as: Plating, manufacturing microelectronics, paper production, coal mines, oil wells, radioactive substances, batteries, metal fabrication, medicine, paint, printing, food, winery, sophisticated technology, woodworking, slaughter, animal husbandry …
Diatomite includes the following properties:
– Ability to remove color and odor of pollutants
– Absorption permeability and selectivity, large surface area and porosity
The special microcrystalline structure consists of cylindrical algae skeletons with a large pore diameter
