Tap water in addition to chlorine method
1, drying: crab tap water in addition to chlorine is most commonly used is the drying method. Use the basin will be ready to change the water catch, and then put into the sun under the sun, through the light and temperature to let the chlorine evaporate. It should be noted that the drying time is different in different seasons, the shortest in summer and the longest in winter.
2, aeration: aeration of the water can also play a role in dechlorination, but also to improve the dissolved oxygen in the water. Compared with conventional drying, aeration is shorter and more efficient, but you need to have a spare oxygen pump, put the gas head inside, a few hours after the chlorine will evaporate clean.
3, medication: If you want to change the water is more, drying and aeration can not meet the words, we need to consider the use of drugs. The so-called medicine is dechlorinating agent, the more common fish Lebao is one of them, but must pay attention to the dosage, once the use of excessive words, it will be harmful to the crab, affecting its development.
4, ozone machine: for families with better economic conditions, the installation of ozone water disinfection system is an effective method of deodorizing and disinfecting water sources. With the ability to generate oxygen free radicals - oxygen free radicals are even more potent than chlorine - it is easy to discharge chlorine from the water while ensuring a high degree of deodorization and sterilization.
5, UV deodorization of chlorine in tap water:
Ultraviolet light has a wavelength of 185nm, which removes chlorine free radicals from water. It has a larger wavelength from 245 to 365 nm and also removes chloramine-chlorinated toxins.
6, activated carbon deodorization of chlorine in water: activated carbon is not only an effective chlorinating agent, but also removes many other toxins in water, such as SO2, NOx, colors, odors, and chloramines due to its large surface area and increased adsorption capacity. Depending on whether the water source is dirty or not, different large activated carbon filters are selected.
