The method of operation of different implementations of water purifiers
Pre-filtration (including steps 1 to 3): The pre-filtration process consists of three steps, which are necessary to prepare water for the main unit of the device (membrane) and to remove harmful substances, especially chlorine, which reduces the efficiency and lifespan of the membrane.
1- The first stage, fiber filter: this filter is made of 100% pure polypropylene compressed 5 microns with a transparent shell to remove mud, sand and other suspended pollution.
The filters used in Dolphin water purifiers are of high quality, which is different from low-quality Chinese filters in the quality of raw materials and the way they are made. The gradient structure of the filters of this device is such that larger particles are trapped in the outer parts of the filter and smaller particles are trapped in the inner parts of the filter, in other words, the density of the filter increases from the outer surface to the inner surface. This density gradient makes optimal use of the filtration capacity.
The clear shell of this step simply shows when to change the filter.
2- The second stage, powdered carbon filter: the carbon used in this filter is made of coconut shell with a white shell to remove chlorine, trihalomethanes and most of the organic chemicals found in insecticides and pesticides, the color, taste and smell of water. , is
3- The third stage, carbon block filter: the carbon used in this filter is made of coconut shell with white shell to complete the function of the second stage and remove the chemicals in the water. The pore structure of this filter is designed to remove the highest amount of chlorine and toxic substances. This filter consists of two layers of polypropylene for pre-treatment.
The carbon filters of stages 2 and 3 are made of coconut shell (Coconut Shell) with Iodine Number >1100, which have a food standard, while the carbon used in low-quality filters is made from coal, which is harmful to health.
The shells used in steps 1, 2, and 3 are made of polycarbonate, which are hygienic, anti-scratch, and resistant to cracking. In addition, their double o-ring prevents water leakage, while low-quality shells are harmful to health, and their single o-ring causes water leakage.
4- The fourth stage, Membrane: Made in Japan Toray Membrane function to remove harmful solutes up to 0.0001 micron, including high hardness of TDS water, dissolved organic substances, microbiological pollutants such as endotoxins, viruses and bacteria, nitrate and nitrite and Heavy metals such as mercury, arsenic, lead, zinc, etc
