Since the early 1990’s, River Sands has been manufacturing and providing a variety of quality graded sands and gravel for water filtration applications both nationally and internationally.
Achieve crystal clear drinking water with River Sands Filter Media. Our products have been used successfully in water treatment plants, tertiary sewerage filtration, industrial water treatment and swimming pools.
River Sands Filtration Media is produced in accordance with the American Water Works Association (AWWA) B100-16 Granular Filter Media Standard. As a qualified manufacture to the AWWA B100-16 Standards, we provide a complete range of granular filtration media. River Sands can also produce filtration media to an agreed specification as supplied.
When you purchase your filter media requirements from River Sands you can be sure that uniformity co-efficients for the filtering material are fully tested, certified, and approved prior to delivery. Additionally, you can reduce project risk by ordering material from a single source with qualifications to manufacture according to the AWWA B100-16 Standards.
Our filter sand is sourced form multiple locations including the 400 million year old Logan River system, to ensure we consistently provide the ideal angularity, size, spherity and hardness for the most efficient filtering of water. River Sands Filter Sands have a slow breakdown rate ensuring a longer filtration life and feature excellent backwashing characteristics, particularly when used in dual media filtration with filter coal.
Our silica sands are clean, hard, sub-rounded and consist of durable particles in accordance with the requirements for the AWWA B100-16. River Sands Filter Sands are typically manufactured from a river sand highest grade quartz.
Due to the size, hardness and spherity of the quartz sand particle sizes along with our proven manufacturing process, our filter sand has tighter tolerances making it more efficient in filtering water. Our filter sand also improves filtering efficiency by reducing retention time and head pressure loss with greater flow rates.
An effective multi-media filter system will utilise larger sized media on top to filter out the larger particles and smaller sized media to filter out the smaller particles. With characteristics such as high specific gravity as well as chemical and abrasion resistance, our Filter Garnet Gravel is ideal for water filtration.
River Sands Filter Garnet is a high hardness, and high density granular filter media. It can be used extremely effectively as the lower layer in a dual media filter system – in conjunction with sand, gravel and anthracite.
Filter gravel is used as a support media to filter sand and coal in water filters. For maximum efficiency, filter gravel must possess the necessary attributes of hardness and be rounded rather than angular. Like the Rivers Sands Filter Sand, our gravels contain hard durable particles with a slow breakdown rate to help prolong the life of the filter.
Our Filter Gravels are clean, hard, sub-rounded particles made from silica and quartz, meeting the stringent requirements for the AWWA B1OO-16. River Sands Filter Gravels are predominantly manufactured from the highest-grade quartz (SiO2>95%).
Australian Bituminous Filter Coal
Australian Bituminous Filter Coal has been used in water filtration projects throughout Australia and New Zealand for more than 30 years. The coal has been developed from pure Australian coal and meets the physical requirements of the AWWA B100-16 Standard. It is recognised as a premium filter media for water and waste water treatment plants, and has been evaluated, approved and implemented by numerous authorities, including Sydney Water, Melbourne Water, SA Water, TasWater, Hunter Water Corporation, SeqWater, and Water Corporation WA.
The coal is composed of cubic-shaped subangular particles that is cleaned, free of clay, shale and other extraneous matter and has minimal fines. The superior particle size grading provides optimum uniformity coefficient and specific gravity allowing for water and energy savings in the backwash process.
Produced in Australia, the Bituminous Filter Coal is light, chemically stable, abrasion resistant and highly durable. It is tested by a laboratory prior to dispatch and guaranteed to meet specifications every time. River Sands can provide test certificates and samples upon request.
Tailor-made for the removal of manganese, iron, hydrogen sulphide, arsenic and radium from water sources, it is processed from the mineral glauconite. It is a silica sand based granular material that acts as a catalyst to promote oxidation of iron and manganese in solution creating a precipitate.
River Sands Manganese Greensand is used alone or in combination with filter coal in dual media filtration systems. It ensures effective reduction of hydrogen sulfide and iron reduction over a wide pH range. Additionally, its tolerance to higher differential pressure can provide longer run times between backwashes and a greater margin of safety. There is also no requirement for extensive preconditioning of the filter media or lengthy start-up periods; and there are no changes required for backwash rates or times or chemical feeds.
