Nature of Silica Sand for Water Filtration You will find various products which suit you on our website. Subsequently, water treatment practice became mainstream after physician John Snow made the connection between the quality of the water and incidences of Cholera in the year 1845/1855. However, this unique way of Filtration got to be refined during the years that followed, culminating with the first global public water supply installation by James Simpson for Chelsea Waterworks company in 1829. The earliest recorded silica sand has been traced back to 1804 when a man by the name John Gibb was able to design and install experimental filters. Silica sand has for a long time been used to purify the water and four grades of silica sand are majorly used for water filtration worldwide. We will address this topic in detail in the following article. This process is known as (testing sand grains by sieves). We use this to pass a specific weight of sand and know the weights of sand with different diameters in each sieve to indicate the percentage of weights of sand grains with different diameters. Meanwhile, to determine the percentage of sand samples’ components based on diameters, we use a set of sieves placed over each other. ☻However, it was soon noticed that samples of sand or gravel taken from any area in the quarry contains grains of different diameters. It was brought from sand quarries and was also discovered to be cheap and available in large quantities compared to other types. ☻After several experiments, silica sand for water filtration was discovered to be the most commonly used in Egypt. Why silica sand is used as filter media for water filtration, and how it works? Thus, many kinds of natural materials were used as a filtering medium, including: ☻The research to determine how to choose a filtering medium for filters, hence, began. ☻Subsequently, several filters were invented, and they were classified according to filtering rates, operating methods, the direction of water flow, and their method of control of the sedimentation process. The use of such filters together with sedimentation process were incredibly beneficial when treatment by chemical clarification is not being used. However, sand filters with high rates were called “Rapid Sand Filters”. ☻In 1880, Patrick Clark developed the slow sand filter, thereby increasing the filtering rate, and reducing the area of land used to construct filters in the United States of America, particularly in New Jersey. This was followed by its extensive use in the United States of America, about 50 years later. ☻ When sand and gravel started to be used for filtration, slow sand filters were used extensively in England and Scotland. Since then, the use of sand filters to treat surface water came to light. ![]() Therefore, this silica sand for water filtration was used as filter to obtain safe drinking water. The idea of filtering water to obtain clean drinking water dates back to the Pharaonic Era, i.e., 4000 BC when researchers found traces of a sand filter in Alexandria dating back to 50AD. It is also safe to store our 20kg bags outside in the weather with no impact to the quality of the product.What you should know about filter sand and gravel Our flexible packaging options include loose 20kg bags, pallets of 20kg bags, and bulk bags. Our Filter Sand meets the most common mesh size used for swimming pool filters is 16/30, however if you require another mesh size please speak with our sales team. River Sands Filter Sand can be used in private and commercial swimming pools, aquatic centre filters, irrigation and filtering potable water. Our Filter Sand is manufactured under an ISO 9001 Quality Assurance system and is compliant with the American Water Works Association standards AWWA B100. The natural, weather-worn silica sand has excellent abrasion resistance and longevity ensuring a long lifespan of use. It is also triple washed to eliminate dust and fine particles. ![]() The sand is kiln-dried at 1000 degrees to kill off any living contaminants like bacteria. The quality of our sand is so high it is used by local council water purification plants throughout Australia. Carefully graded to #7C, our Filter Sand optimizes water flow and filtration efficiency. River Sands Filter Sand purifies water and is a great option for your pool sand filter.
