Manganese Sand

Key features:

High-efficiency iron and manganese removal: Through the surface oxide layer, divalent iron (Fe²⁺) and divalent manganese (Mn²⁺) in water are converted into insoluble trivalent iron (Fe³⁺) and tetravalent manganese (Mn⁴⁺). The iron removal rate can reach 99%, and the manganese concentration can be reduced to below 0.1 mg/L.

No chemical additives required: It only needs to be used in conjunction with aeration or contact oxidation equipment, without the need to add additional chemicals. It is environmentally friendly and has low operating costs.

Long service life and stability: High mechanical strength, stable chemical properties, service life can reach 3 to 5 years, and the backwashing loss rate is low.

Composite filtration structure: It is often combined with quartz sand, activated carbon, etc., to form multi-layer filtration and improve the accuracy of pollution interception.

Application scenarios:

Groundwater treatment (such as rural water supply and industrial water use);
Pretreatment of high-iron manganese water quality (such as in the petroleum and textile industries)

Quartz Sand

Key features of Mod:

High-efficiency suspended solids removal: Through mechanical retention and surface adsorption, it can remove suspended solids, colloids, bacteria, etc., and the effluent turbidity is less than 5 NTU.

Adaptive filtration: The filter bed automatically forms a "loose at the top and dense at the bottom" structure, which can adapt to different water quality conditions and has a good backwashing effect.

Acid and alkali resistance and anti-pollution: It has a wide pH range of application (2-13), strong oxidation resistance, and is suitable for treating water with high turbidity.

Fast filtering: The filtering speed reaches 7-30 m/h, suitable for high-traffic scenarios.

Application scenarios:

Industrial water pretreatment (such as RO systems, cooling circulating water);
Municipal water supply and swimming pool circulation purification

Activated Carbon

Key features:

Adsorb broad-spectrum pollutants: Effectively remove residual chlorine, organic compounds (VOCs), pesticides, odors and some heavy metals (such as lead and mercury).

Improve taste and safety: Significantly reduce the chlorine taste, enhance the palatability of drinking water, and lower the risk of water-borne diseases.

Environmental protection and economy: Replace bottled water and reduce plastic pollution; It is easy to maintain and the replacement cycle is 6 to 12 months.

Multi-functional combination: It is often used in combination with quartz sand and manganese sand to enhance the comprehensive purification effect (such as adsorbing organic matter after removing iron and manganese).

Application scenarios:

Household water purifiers, food and beverage industry;
Advanced treatment of industrial wastewater (such as dye factories, pharmaceutical factories)
