What is a sand filter?

The sand filter is a device that uses sands as a natural filter substance for clean water. Like water in underground Aquifers, it is clean by browsing through various layers of sand and porous rocks, the sand filter is trying to take its own nature design and use it too. Unlike other types of filters, sand filters can be very environmentally friendly products that are often used in pools and even commercial wastewater applications. The most common task to be performed is to clean the pool filter, usually approximately once a month. This is done by flushing or perverting the water flow by the filter and then destroying this water. In some cases, it is recommended to change the sand filter to maintain a certain level of efficiency. Many experiments with pool maintenance and shops recommend changing sand into a filter every five to seven years. The sand is dimensioned and shaped in a way that prevents very small particles from passing, often only 20 microns. Over timeThe sand of the harsh edge and is less effective. So the system must spend more time running to filter, just like when the sand was new. This can shorten the life of the sand filter.

The sand filter is one of the most common types of filters used for pools. At the residential pool, they usually start at approximately $ 400 in USD (USD). However, the costs are often dependent on the size of the needed filter and perhaps on the selected brand. However, for larger pools and water parks, the sand filter can occupy a large amount of space and more thousands of dollars. The advantage of the sand filter is that it is usually capable of the last few decades is not abused and well maintained over the years.

sand filters can also be used in other types of applications, including commercial water purification systems for drinking and waste water. In these situations, biofilm is formed on the upper part of the sand. It has a consistency similar to gelatin. Biological elements of pomThey are to spend and remove harmful bacteria. Upon completion, water filtering can be almost completely free of bacteria.
