Combined with the previous discussion on white zeolite powder and other water treatment materials, the main materials required for water treatment are categorized as follows:
1. Filtration and Adsorption Materials
These are the core consumables for water treatment, designed to intercept and adsorb pollutants in water:
Quartz Sand: The most basic filter medium with low cost, which can effectively intercept suspended solids and sediment in water, serving as the first-layer filtration material for most water treatment systems.
White Zeolite Powder: Relying on its unique ion-exchange structure, it can efficiently and selectively adsorb ammonia nitrogen and heavy metal ions in water, widely applied in scenarios such as drinking water purification and aquaculture water treatment.
Activated Carbon: With abundant pore structures, it adsorb odors, residual chlorine and trace organic pollutants in water, acting as the core material in the advanced water purification stage.
Hematite Ore: It can assist in removing metal ions like iron and manganese from water, commonly used in the pre-treatment stage of industrial wastewater.
2. Flocculation and Precipitation Materials
These materials enable tiny suspended impurities in water to agglomerate into large flocs for rapid sedimentation and separation:
Poly Aluminum Ferric Chloride (PAFC): A high-efficiency inorganic flocculant suitable for various scenarios including industrial wastewater and municipal sewage, featuring fast sedimentation speed and stable treatment performance.
Polyacrylamide: As a high-molecular coagulant aid, it works with inorganic flocculants to significantly improve the compactness of flocs and reduce sludge output.
3. Functional Auxiliary Materials
These materials are used to adjust water quality parameters and optimize the operation effect of water treatment systems:
Modified Calcium Carbonate: It can adjust the pH value of water and assist in adsorbing part of heavy metals. In some sewage treatment scenarios, it can replace part of special water treatment fillers to reduce operation costs.
Ion Exchange Resin: Used in scenarios such as hard water softening and pure water preparation, it can accurately remove calcium and magnesium ions in water to produce high-purity purified water.
