Powdered activated carbon has two dosing methods: wet method and dry method. The wet dosing process: feeding-storage-preparation of activated carbon slurry (feeding and water supply)-mixing and stirring-quantitatively dosing by metering pump to the dosing point. Dry dosing process: feeding-storage-continuous quantitative dosing of activated carbon-dosing from the jet to the dosing point.
The wet process adopts the method of preparing activated carbon slurry, which is quantitatively delivered to the dosing point by a metering pump. The activated carbon slurry is dosed by a metering pump. The dosage of activated carbon slurry can be controlled very accurately, but the preparation concentration of activated carbon slurry has a high precision ,powdered activated carbon pac It is mainly to control the dosage of powdered carbon and the amount of water supply. If the accuracy of the concentration of activated carbon slurry is low, although the metering pump maintains the accurate flow rate of the slurry, the accurate dosage of activated carbon powder cannot be obtained.
The dry process uses the feeding equipment to put the carbon powder into the ejector directly, and the carbon powder is added to the dosing point through the ejector. The metering of the powdered carbon is completed by the feeding equipment, and only the feeding is guaranteed. The dosing accuracy of the equipment can guarantee the dosing accuracy of powdered carbon (the carbon powder feeding equipment for wet and dry processes are both quantitative dosing equipment), and the dry process only considers the dosing accuracy of carbon powder without thinking (Preparation of carbon slurry) The water flow only considers the pressure at the outlet of the ejector. Therefore, it is easier to ensure the accuracy in controlling the accuracy of carbon powder dosing than the wet process.
It is generally believed that the average after the wet process is better. The main consideration is that the carbon powder and water can be stirred in the mixing tank to obtain a very evenly mixed slurry, so it is sent to the dosing point through the metering pump (water pipe After the road), the dispersion of carbon powder in the pipeline is better.activated carbon pellets for air filter uk In fact, it cannot be assumed that the mixing average degree of activated carbon slurry is high, which can achieve the effect of high dispersion averageness of activated carbon in the water intake pipeline. Moreover, in the dry process, the carbon powder passes through the jet, its average degree (in the jet water) Also very high.
