Diatomite Market Share Of Wastewater Safely Treated In 2022 By Reg
Dublin, Aug. 20, 2026 (GLOBE NEWSWIRE) — “Diatomite – Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026-2031)” has been added to ResearchAndMarkets.com’s offering.
Global Diatomite Market to Reach 2.74 Million Tons by 2031 as Filtration and Water Treatment Demand Accelerates
The global diatomite market is projected to grow from 2.01 million tons in 2025 to 2.12 million tons in 2026 before reaching 2.74 million tons by 2031. The market is forecast to expand at a compound annual growth rate of 5.23% from 2026 to 2031, supported by rising demand for filtration media, expanding water and wastewater treatment infrastructure, and increased consumption of calcined grades in construction materials.
Filtration Applications Drive Global Diatomite Market Growth
Food and beverage producers remain major consumers of diatomite filter media. Breweries and wineries use the material to remove yeast, bacteria, and haze while maintaining product flavor and enabling filtration at relatively low operating pressures. Regulatory acceptance from organizations including the U.S. Food and Drug Administration and the International Organisation of Vine and Wine continues to provide certainty for beverage manufacturers.
Water treatment is another important source of diatomite market demand. Municipal utilities use diatomite precoat filtration systems to support protozoan removal and improve water quality. These systems can also generate less sludge than conventional coagulation processes, helping utilities reduce disposal requirements and operating costs, particularly in water-stressed regions.
Major infrastructure initiatives are creating long-term opportunities for diatomite suppliers. India’s Jal Jeevan Mission and AMRUT 2.0, China’s rural wastewater programs, and desalination upgrades across the Middle East are increasing demand for efficient filtration technologies. Diatomite filters are particularly suitable for decentralized facilities because they require comparatively low energy input and offer short media replacement cycles. Pilot projects in Saudi Arabia have also indicated that diatomite pretreatment may reduce reverse-osmosis fouling and lower water production costs.
Calcined and Flux-Calcined Grades Gain Momentum
Calcined diatomite represented 46.27% of global supply in 2025, reflecting its mechanical strength and ability to support low-turbidity filtration. Flux-calcined grades are expected to record particularly strong growth, advancing at an estimated 6.18% annually as beverage producers seek filtration media capable of delivering lower pressure drops and improved throughput.
Production of flux-calcined diatomite requires precise kiln controls, washing, and quality monitoring to meet stringent food and beverage specifications. Suppliers with advanced processing equipment and laboratory capabilities are positioned to address premium applications, while smaller producers continue to focus on natural grades used in absorbents, fillers, agriculture, and pet-litter products.
Construction applications are also supporting market expansion. Calcined diatomite is increasingly used in lightweight concrete, cement additives, insulation products, and thermal-performance building materials. However, competition from expanded perlite, silica sand, fly ash, slag, and synthetic filtration media may constrain growth in price-sensitive or highly specialized applications.
Freshwater Diatomite Maintains Market Leadership
Freshwater diatomite accounted for 64.38% of market volume in 2025 due to its purity and established performance in beverage filtration. Saltwater diatomite is forecast to expand at a 5.84% CAGR as high-purity inland deposits mature and producers develop coastal resources in Peru, Turkey, and Mexico.
Marine deposits can provide logistical advantages through proximity to export ports and Asian customers. Nevertheless, saltwater diatomite generally requires additional beneficiation, adding an estimated USD 20 to USD 35 per ton to processing costs. Consistent pore-size distribution and standardized quality remain essential because breweries and other industrial customers conduct rigorous validation before approving alternative grades.
Asia-Pacific Leads Regional Diatomite Demand
Asia-Pacific represented 47.63% of global diatomite demand in 2025 and is projected to grow at a 5.91% CAGR through 2031. China’s wastewater investment, India’s large-scale drinking water and urban infrastructure programs, and expanding industrial treatment requirements across Southeast Asia are strengthening regional consumption. Japan and South Korea are also evaluating diatomite-based silicon for emerging battery applications.
North American growth is expected to remain moderate as some mature filtration users transition to membrane systems. Nevertheless, demand continues across beverage clarification, industrial processing, oil-sands filtration, and specialty applications. Mexico’s tequila industry is among the regional markets requiring filtration media with consistent performance characteristics.
Europe is benefiting from demand for calcined pozzolan blends and energy-efficient construction materials, although low-cost substitutes and proposed crystalline-silica exposure requirements may increase compliance costs. South America, the Middle East, and Africa offer emerging opportunities through wine clarification, lightweight building panels, mineral processing, desalination, and lower-clinker cement production.
Despite competition from alternative materials and limited availability of high-purity deposits, the global diatomite market outlook remains positive. Continued investment in clean water infrastructure, beverage production, industrial filtration, sustainable construction, and agricultural absorbents is expected to support steady market growth through 2031.
