In modern agriculture, soilless culture, flower cultivation and fruit tree cultivation have become efficient, productive and environmentally friendly cultivation methods. However, these cultivation methods are extremely demanding in terms of irrigation water quality, especially the control of electrical conductivity (EC value). Water sources with high EC values can lead to overnutrient overnutrition, affecting growth and even death. Therefore, it is particularly important to know how to reduce the EC value of water sources in these cultivation methods. Let's follow the champion Wang Purification Water today to find out
Interception and removal of suspended solids
Suspended solids are insoluble solid particles in water, which can come from soil, organic matter, microorganisms, etc.
When the water passes through a physical interception device (e.g. strainer, sand filter, etc.), these suspended solids are trapped inside the filter and thus separated from the water.
Due to the various ions in suspended solids, their removal leads to a decrease in the concentration of the corresponding ions in the water, which in turn reduces the EC value.
Filtration and removal of dissolved impurities
Dissolved impurities refer to those substances that are dissolved in water in ionic or molecular form, such as salts, organic matter, etc.
Filter materials (e.g., filter cotton, activated carbon, etc.) have an adsorption effect that can adsorb and remove these dissolved impurities.
As dissolved impurities are removed, the ions in them are also removed, reducing the ion concentration and EC value in the water.
Reverse osmosis purification
Reverse osmosis is an advanced membrane separation technology with extremely high filtration accuracy, typically up to 00001 microns.
Reverse osmosis membranes allow only water molecules to pass through, while most of the dissolved salts, organics, and ions are trapped on one side of the membrane, allowing them to separate from water.
Through reverse osmosis purification, it is very effective in removing ions from the water, drastically reducing the EC value and obtaining almost pure water.
