#Silica water portable
As a result of its uniqueness in terms of its properties, silica sand is usually used for water filtration in a wide variety of applications that include swimming as well as leisure, paper processing, power generation, chemical processing, and portable as well as wastewater treatment. Incoming water enters the filter and then migrates through silica sand, successfully removing any solid or debris from the water. This is either by using the size range, the Effective size (D10) or UC.įurther, Silica sand gets laid on top of the supporting layer of the Gravel within the filter vessel. However, when it comes to the silica grade, it can easily be determined. Due to high silica content, sand is durable and hard-wearing, allowing it to be graded precisely to facilitate efficient filtering.
So, how exactly does it work? Natural silica sand has a sub-angular to a rounded shape, making them an ideal filtration media to capture suspended solids in water. Today, the provision of good quality potable water is taken for granted in most of the developed World.

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.
#Silica water install
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:
#Silica water how to
☻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.
