Diatomite for sustainable development architectural decoration air purification water treatment eco friendly production porous structure adsorption capacity industrial applications interior finishes
With the increasing awareness of environmental protection worldwide, the treatment of waste gas and wastewater has become a key task for enterprises to achieve green development. The efficient removal of odors and volatile organic compounds (VOCs) in waste gas, as well as the adsorption of harmful substances in wastewater, has become a technical focus. High adsorption diatomaceous earth powder (diatomite powder) has become an ideal environmental protection material due to its large specific surface area, strong adsorption capacity, and natural non-toxic properties, and is widely used in waste gas treatment, wastewater treatment, and solid waste disposal.
In waste gas treatment, especially in the treatment of industrial waste gas containing VOCs (such as printing, painting, and chemical industry), diatomaceous earth powder can effectively adsorb harmful substances. The porous structure of diatomite powder has a large number of adsorption sites, which can capture VOC molecules through van der Waals forces and electrostatic attraction. After modifying the surface of diatomaceous earth powder (such as loading activated carbon, titanium dioxide, etc.), its adsorption capacity for VOCs can be further improved. Taking the painting workshop of an automobile manufacturing plant as an example, the waste gas contains a large amount of benzene, toluene, and xylene. After passing the waste gas through a filter bed filled with modified diatomaceous earth powder, the removal rate of benzene, toluene, and xylene can reach more than 90%, and the concentration of VOCs in the treated waste gas is lower than the national emission standard (≤80 mg/m³). Compared with traditional activated carbon adsorption, diatomaceous earth powder has the advantages of low cost, long service life (adsorption saturation time is 2-3 times that of activated carbon), and easy regeneration (can be regenerated by heating at 300-400°C, and the adsorption capacity can be restored to more than 85% after regeneration).In the treatment of odorous waste gas (such as waste treatment plants, sewage treatment plants, and livestock farms), diatomaceous earth powder can also play a good role in deodorization. Odorous substances mainly include ammonia, hydrogen sulfide, and mercaptans. The porous structure of diatomite powder can adsorb these odorous molecules, and the alkaline or acidic functional groups on its surface (after modification) can react with odorous substances to decompose them into harmless substances. A waste treatment plant in a coastal city used a deodorization system based on diatomaceous earth powder. After installation, the odor concentration around the plant was reduced from 5000 OU/m³ to less than 200 OU/m³, which was far lower than the national standard (≤400 OU/m³), and the complaints from nearby residents were reduced by 90%. At the same time, the diatomaceous earth powder used in the deodorization system can be reused after regeneration, reducing the amount of solid waste generated.In wastewater treatment, high adsorption diatomaceous earth powder can be used to treat industrial wastewater containing organic pollutants (such as printing and dyeing wastewater, chemical wastewater). Printing and dyeing wastewater contains a large number of dyes and auxiliaries, which have high chroma and COD, and are difficult to degrade. Adding 2-5% diatomaceous earth powder to the wastewater can adsorb the dyes and organic matter in the water. Tests show that the chroma removal rate of printing and dyeing wastewater can reach more than 95%, and the COD removal rate can reach 60-80%. Compared with traditional coagulants (such as aluminum sulfate), diatomaceous earth powder has no secondary pollution (no aluminum ion residue), and the sludge generated after treatment is easy to dehydrate and can be used as a building material additive after harmless treatment. A printing and dyeing factory in Zhejiang used diatomaceous earth powder to treat its wastewater. After treatment, the wastewater can be recycled for production (after further advanced treatment), reducing the factory’s water consumption by 30% and saving a lot of water costs.Our high adsorption diatomaceous earth powder for environmental protection has a variety of product forms, including powder, granular, and extruded. The powder form (100-800 mesh) is suitable for wastewater treatment and waste gas adsorption towers; the granular form (1-5 mm) is suitable for fixed-bed adsorption systems in waste gas treatment; the extruded form (5-10 mm) is suitable for large-scale waste gas treatment projects with high air volume. The main technical indicators of our products are: specific surface area ≥200 m²/g, pore volume ≥0.8 cm³/g, adsorption capacity for methylene blue ≥15 mL/0.1g, and moisture content ≤3%. We can also provide modified diatomaceous earth powder products according to customers’ specific treatment objects, such as activated carbon-loaded diatomite powder (for VOCs adsorption), titanium dioxide-loaded diatomite powder (for photocatalytic degradation of organic pollutants), and alkaline diatomite powder (for hydrogen sulfide adsorption).In the production process, we adopt advanced activation technology to enhance the adsorption capacity of diatomaceous earth powder. The activation process includes acid activation (using dilute sulfuric acid to etch the surface of diatomite particles, increasing the number of pores) and thermal activation (calcining at high temperature to remove organic impurities in the pores and expand the pore size). The activated diatomaceous earth powder has a specific surface area increased by 30-50% compared with the original ore, and the adsorption capacity is significantly improved. Each batch of products will undergo adsorption capacity testing (using methylene blue solution as the adsorbate) and pore structure testing (using a specific surface area analyzer), ensuring that the product performance meets the requirements.

Diatomite powder leads global green industry innovation with outstanding performance and wide-ranging usability
Diatomite powder, a naturally occurring mineral product with widespread industrial value, originates from fossilized remains of diatoms—microscopic algae that thrive in freshwater and saltwater environments worldwide. These tiny organisms, with silica-based cell walls, multiply rapidly in nutrient-rich waters, and upon death, their cell walls sink to bottom of water bodies, forming thick sediment layers. Over millions of years, these sediments undergo gradual compaction and mineralization under pressure of overlying geological layers, transforming into diatomite ore. Through crushing, grinding, and purification processes, this ore is converted into fine diatomite powder with consistent particle size. What makes diatomite powder stand out is its unique porous structure—each particle contains countless tiny, interconnected pores that form intricate network. This structure gives diatomite powder exceptional surface area, allowing it to exhibit remarkable adsorption, filtration, and insulation properties. Such inherent characteristics make diatomite powder a valuable material across diverse industries, from construction to environmental protection, and from industrial manufacturing to emerging technology sectors.In construction sector, diatomite powder plays irreplaceable and crucial role, becoming integral component in eco-friendly building materials. When incorporated into wall coatings and plasters, diatomite powder interacts seamlessly with other ingredients to enhance thermal insulation and sound absorption capabilities of products. For instance, in residential and commercial buildings, wall coatings infused with diatomite powder create barrier that slows heat transfer between indoor and outdoor spaces, keeping interiors cooler in summer and warmer in winter. This thermal insulation effect reduces need for constant operation of heating and cooling systems, contributing significantly to energy conservation. In terms of sound absorption, porous structure of diatomite powder traps sound waves as they hit wall surfaces, reducing echo and noise transmission between rooms or from outside environment—making it ideal for use in schools, hospitals, and office buildings where quiet environments are essential. Another key advantage of diatomite powder in construction is its humidity regulation ability. In wall coatings and plasters, it acts as natural moisture regulator: when indoor air is overly humid, diatomite powder absorbs excess moisture into its pores; when air becomes dry, it releases stored moisture back into environment. This cycle maintains stable indoor humidity levels, preventing mold growth on walls and creating more comfortable living and working spaces. Additionally, inherent fire-resistant nature of diatomite powder makes it preferred additive in fireproof coatings and panels. When exposed to high temperatures, diatomite powder releases negligible toxic fumes and maintains structural stability, forming protective layer that slows spread of flames. This property is widely utilized in high-rise buildings, industrial workshops, and public venues, greatly improving overall safety of buildings. Many construction material manufacturers now prioritize diatomite powder in product formulations, as it aligns with growing demand for green, energy-efficient, and safe building solutions.Environmental protection industry also reaps significant benefits from unique properties of diatomite powder, emerging as sustainable solution for water and air purification challenges. Exceptional adsorption capacity of diatomite powder stems from its porous structure, which acts like sponge to effectively trap impurities, heavy metals, and harmful substances in water and air. In water treatment, diatomite powder is widely used in filtration systems for both drinking water and wastewater purification. For drinking water treatment plants, diatomite powder is added to filtration tanks where it adheres to suspended particles, organic matter, and trace heavy metals, forming filter cake that removes these contaminants. This process ensures water meets strict safety standards, delivering clean drinking water to communities. In wastewater treatment, especially from industrial facilities and municipal sewage systems, diatomite powder targets specific pollutants such as oil residues, chemical solvents, and heavy metal ions. It not only removes visible impurities but also reduces concentration of harmful substances, making treated water suitable for reuse in irrigation or industrial processes, thus promoting water recycling. In air purification, diatomite powder serves as key component in filters and adsorbents used in homes, offices, and industrial settings. Air purifiers equipped with diatomite-based filters draw in polluted air, and porous structure of diatomite powder captures dust particles, pollen, and volatile organic compounds. Unlike some synthetic adsorbents, diatomite powder can also decompose certain volatile organic compounds through natural oxidation processes, rather than just trapping them, providing long-lasting air purification effects. It is also used in industrial air filtration systems, such as those in factories and power plants, to remove smoke, dust, and harmful gases, reducing emissions into atmosphere. Moreover, diatomite powder is biodegradable and non-toxic, so spent filters containing diatomite powder do not pose secondary environmental pollution risks. This combination of effectiveness and eco-friendliness makes diatomite powder sustainable choice for eco-friendly environmental protection solutions, gaining increasing recognition from environmental agencies and industries worldwide.In industrial realm, diatomite powder finds extensive and diverse use, particularly in filtration processes and manufacturing of specialized products. As filter aid, diatomite powder is indispensable in production of beverages, oils, and chemicals, where clarity and purity of final products are critical. In beverage industry, for example, during beer and wine production, diatomite powder is added to filtration systems to remove yeast cells, sediment, and other suspended particles. Its porous structure forms stable filter bed that traps impurities while allowing liquid to pass through smoothly, resulting in clear, transparent beverages with improved taste and shelf life. Similarly, in edible oil refining, diatomite powder filters out residual solids, pigments, and off-flavor compounds, enhancing quality of cooking oils and ensuring they meet food safety standards. In chemical industry, it is used to filter solutions during production of paints, inks, and pharmaceuticals, removing undissolved particles and ensuring consistency of final products. Beyond filtration, diatomite powder plays vital role in manufacturing of ceramics and refractories. When added to ceramic raw materials, it acts as reinforcing agent that improves mechanical strength and durability of finished products. It also reduces shrinkage during firing process, preventing cracking and ensuring uniform shape of ceramic items such as tiles, pottery, and industrial ceramics. In refractories—materials used in high-temperature environments—diatomite powder’s high-temperature resistance and thermal stability make it ideal component. Refractory bricks and linings containing diatomite powder maintain structural integrity under extreme heat, making them suitable for use in industrial furnaces, kilns, and incinerators. These refractories not only withstand high temperatures but also provide thermal insulation, reducing heat loss and improving energy efficiency of industrial processes. Additionally, diatomite powder is used in production of cat litter, where its high absorption capacity traps moisture and odors effectively. It is also employed in paper industry as filler and coating agent, improving opacity and printability of paper. Such wide-ranging industrial applications highlight versatility of diatomite powder and its ability to enhance performance and efficiency of various manufacturing processes.Beyond construction, environmental protection, and industrial sectors, diatomite powder is making significant inroads into agriculture industry—focusing on soil amendment and pest control, while strictly avoiding direct involvement in planting aspects. In soil amendment, diatomite powder addresses common soil issues by improving overall structure and fertility. When added to compacted or clay-heavy soils, porous structure of diatomite powder creates air pockets that enhance aeration, allowing plant roots to access oxygen more easily. This improved aeration also prevents waterlogging, reducing risk of root rot. At same time, diatomite powder’s water retention capacity helps sandy soils hold moisture and nutrients longer, ensuring plants receive consistent hydration and nourishment. It also acts as carrier for beneficial microorganisms and nutrients: when mixed with organic fertilizers, diatomite powder slowly releases nutrients into soil, extending fertilizer effectiveness and reducing nutrient leaching. Farmers and gardeners often use diatomite powder in organic farming and horticulture, as it helps build healthy soil ecosystem without introducing synthetic chemicals. In pest control, diatomite powder serves as effective natural alternative to chemical pesticides. Its abrasive properties, derived from sharp edges of its porous particles, damage exoskeletons of harmful insects such as aphids, beetles, and mites. When insects come into contact with diatomite powder, it absorbs waxy layer on their exoskeletons, leading to dehydration and death. Unlike chemical pesticides, diatomite powder is non-toxic to humans, pets, and beneficial insects such as bees and ladybugs, making it safe for use in organic farms, greenhouses, and home gardens. It can be applied directly to soil surface, around plant bases, or mixed with feed to control pests in livestock facilities. Many organic farming certifications recognize diatomite powder as approved pest control and soil amendment product, further boosting its adoption in agriculture industry. Its dual role in improving soil health and controlling pests makes diatomite powder valuable tool for promoting sustainable and organic farming practices.Global market for diatomite powder is experiencing steady and robust growth, driven by increasing global awareness of sustainability and rising demand for eco-friendly materials across industries.
