NATURAL SAND FILTER MEDIA
BSR & CO is one of the leading manufacturers of natural sand for the potable water, wastewater and pool industries since 2017.
BSR & CO Natural Sand is extracted from a clean river sand deposit. It has a proper angularity, hardness, sphere city and size and hence meets the criterion to be categorized into high-quality filter sand. The angular shape of the uncrushed filter sand enhances the flow and ensures even distribution. To meet the exact specifications of fine quality filter sand, BSR & Co filter sand is cleaned, dried and screened with strict adherence to quality control. It is a perfect filter media for all applications.
BSR & Co Natural Sand is graded specifically for water filtration plants. Our Sand and Gravel water filtration media is a naturally clean filtration media useful for applications related to industrial, municipal and household water treatment.
Slow Filter Sand
0.15 to 0.30 mm
Mixed Filter Sand
1.5 - 3.35 mm
A sand filter is part of a water filtration system and its role is to remove suspended, floating, and sinkable matter from water so that it becomes safe for use. It has the capacity to remove ammonia, protozoa, and bacteria. The system is so designed that it is easy-to-operate and also requires very little maintenance.
Coarse Silex
6 - 14 mm
Fine Filtering Sand
16 - 32 mesh or 0.6 - 1.18 mm
Fine sand is a filter media used in ideal pre-treatment process for water containing waterborne parasites, bacteria and suspended solids that cause turbidity, color, taste and odour. It is effective at treating groundwater with high iron and dissolved gases.
Fine Silex Sand
1/4"-1/10" inch or 4 - 6 mm
Natural Silex Filter Sand is used as last layer of sand in filter bed. Below silex sand, support pebbles are layered out to support sand layers. Importance of filter sand, to work for physical treatment- catching the turbidity component suspended in rapid filtration and for biological treatment in slow filtration. High quality filter sand requires the proper angularity, hardness, spherecity and size. Silex Sand improves efficiency by reducing retention time and head pressure loss with greater flow rates.
Gravel & Pebbles
10 - 20 mm
Our filter gravel & pebbles are naturally rounded and predominantly quartz aggregate. Available washed and screened to specific sizes.
Sand Filteration
Sand filtration is used for the removal of suspended matter, as well as floating and sinkable particles. The wastewater flows vertically through a fine bed of sand and/or gravel. Particles are removed by way of absorption or physical encapsulation. If there is excessive pressure loss on the filter, it must be rinsed.
A distinction can be made between continuous and discontinuous filters. In continuous filters (often upward-flowing filters), the polluted sand is removed, rinsed and re-used continuously, without interrupting the filtration process. Discontinuous filters (often downward-flowing filters) are stopped, and a rinse takes place in the opposite direction. Air bubbles are blown into the sand bed to make it swirl around. Filtered water then flows through the filter bed in the opposite direction. The polluted matter is released and flows away along with the rinse water. The filtration process can then resume.
The yield of a sand filter is determined by two sand filter functions, namely surface filtration and depth filtration. Surface filtration involves collecting the particles above the filter bed. These particles jointly form a macro-porous lump, which is able to collect new particles in a very effective manner. Depth filtration generally involves smaller particles that are more difficult to collect, and which are bound to the sand particles by adsorption. Dirt from surface filtration is easier to remove during reverse rinsing compared to dirt from depth filtration.
Below are a few implementation examples:
- Iron-removal from groundwater using aeration and sand filtration.
- Final purification of wastewater, follow-up to metal precipitation and sedimentation, to remove residual traces of metal-based sludge.
- Final purification of wastewater produced in the production of iron, steel and non-ferro alloys. Sand filtration can be preceded by processes like precipitation/sedimentation, coagulation/flocculation/sedimentation and flotation.
- Purification of wastewater containing sand-blasting grit and paint particles, at shipyards for example.
- Also used as final purification (or prior to active carbon filtration) to permit re-use.
- Used in greenhouse horticulture as drain-water disinfectant (slow sand filter)
