When pure water treatment equipment is used in winter, our water treatment equipment manufacturers should pay more attention to it. After work, first of all, we should check whether the equipment has the appearance of freezing. Let's take a look at the techniques used in winter with the environmental protection of mountains and rivers.

1. With the increasing use of water treatment equipment, water production will be reduced in Hangzhou, but water production will become less in winter. This is because the water temperature and low permeability will become smaller, and the density of reverse osmosis membrane will change accordingly. These two reasons will lead to less water production. Let's operate reverse osmosis pure water equipment. More careful and thorough, strengthen the number of backwash of pretreatment device, add washing time, change filter element frequently, increase backwash time of reverse osmosis membrane, increase pressure less sharply, so as to ensure the normal operation of pure water treatment equipment.

2. When the water temperature drops by 1 C, the water yield of reverse osmosis membranes decreases by 3%, and the water yield in winter is about 50% of that in summer. When the water yield decreases, the flow of wastewater will be added accordingly and the ratio of wastewater will increase, which is a normal phenomenon. When the temperature rises, the wastewater will be reduced and the flow of water will be added.

3. If the device is outdoors, it is necessary to have anti-freezing measures. If there is no anti-freezing measures, it may cause freezing cracks of filter bottles, membrane shells and so on. It is necessary to stop using water treatment equipment when the temperature is below zero.

4. It is necessary to ensure that the room temperature of the device is not less than 0 degrees, because the volume of water will expand during the condensation process. If it freezes, all the pipes, filter bottles and membrane shells of the water purifier will burst and then leak.
