Our 0.5\u20130.8mm Fine Sand<\/b> is not standard construction sand; it is high-purity silica filter media<\/b> engineered for high-performance mechanical filtration. The uniform grain size ensures an even flow distribution throughout the filter bed, preventing “channeling” where water bypasses the media without being cleaned.<\/p>\n Precision Filtration:<\/b> Its 0.5\u20130.8mm size is the “sweet spot” for trapping microscopic debris, algae, and sediments as small as 20\u201350 microns.<\/p>\n<\/li>\n Chemical Inertness:<\/span><\/b> Being high-purity silicon dioxide, this sand does not react with chemicals or leach impurities into your water, ensuring the final output is safe and odorless.<\/span><\/p>\n<\/li>\n Long Service Life:<\/b> The high hardness of the quartz grains ensures that the media resists abrasion.<\/span> This allows for thousands of backwash cycles<\/b> without significant loss of material or filtration quality.<\/p>\n<\/li>\n Multi-Media Compatibility:<\/b> This grade is the perfect middle-layer for multi-media filters, often paired with coarse gravel at the bottom and anthracite at the top for advanced turbidity removal.<\/p>\n<\/li>\n Cost-Effective Maintenance:<\/b> Because the sand is pre-washed and dust-free, it reduces initial rinsing time and minimizes the risk of clogging your underdrain system.<\/p>\n<\/li>\n<\/ul>\n Swimming Pool Filtration:<\/b> Compatible with all major brands of sand filter pumps to keep pool water sparkling and clear.<\/p>\n<\/li>\n Reverse Osmosis (RO) Pre-treatment:<\/span><\/b> Protects expensive RO membranes by removing larger particles that cause premature fouling.<\/span><\/p>\n<\/li>\n Drinking Water Purifiers:<\/b> Used in domestic and municipal gravity or pressure filters to treat groundwater and well water.<\/span><\/p>\n<\/li>\n Industrial Wastewater:<\/b> Helps in the tertiary treatment of industrial effluent before discharge, ensuring environmental compliance.<\/p>\n<\/li>\n<\/ul>\n Achieve crystal-clear water with our premium 0.5\u20130.8mm Fine Sand<\/b>. This triple-washed, kiln-dried silica sand is precision-graded for maximum filtration efficiency. Specifically designed for pressure sand filters and domestic water purifiers, it effectively removes suspended solids, silt, and turbidity, making it the industry standard for clean water in Sri Lanka.<\/p>\n Grain Size:<\/b> 0.5\u20130.8mm (Fine\/Medium Grade).<\/p>\n<\/li>\n High Purity:<\/b> Washed and screened to remove dust, clay, and organic impurities.<\/p>\n<\/li>\n Mechanical Strength:<\/b> Hard quartz structure (6\u20137 Mohs) prevents crumbling during backwash.<\/span><\/p>\n<\/li>\n Ideal Use:<\/b> Drinking water plants, swimming pools, and industrial RO pre-treatment.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"featured_media":9269,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[35,24],"product_tag":[],"class_list":{"0":"post-9257","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-filter-media","7":"product_cat-water-filters","8":"desktop-align-center","9":"tablet-align-center","10":"mobile-align-center","12":"first","13":"instock","14":"taxable","15":"shipping-taxable","16":"purchasable","17":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product\/9257","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/comments?post=9257"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media\/9269"}],"wp:attachment":[{"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/media?parent=9257"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_brand?post=9257"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_cat?post=9257"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/prudenceeng.lk\/shop\/wp-json\/wp\/v2\/product_tag?post=9257"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Key Features & Benefits:<\/b><\/h3>\n
