What causes the reverse osmosis equipment to cause fouling during use?
Water treatment equipment will cause fouling of reverse osmosis membranes due to various reasons in the operation of reverse osmosis. Today, editor from Volardda will explain the reasons for fouling and blocking.
There are three main reasons for the fouling of reverse osmosis membranes:
1. The characteristics and functions of the reverse osmosis membrane are damaged,causing fouling and blocking
The main reasons are that the storage time of the reverse osmosis membrane exceeds one year; the maintenance of the reverse osmosis membrane is not standardized; the shutdown operation at the end of the water treatment equipment is not appropriate.
2. Membrane fouling caused by frequent changes in water quality
In this case, the water quality of the raw water is often different from the water quality designed to be treated, which increases the load of the water treatment equipment, and the water to be treated contains various impurities such as inorganic substances, which also increases the probability of reverse osmosis membrane fouling.
3. The cleaning method of reverse osmosis membrane is inappropriate or not timely
In the normal use process, in addition to the attenuation of the normal function of the reverse osmosis membrane, the untimely cleaning or improper cleaning method will cause the fouling of the reverse osmosis membrane.
In our daily life, we use treated pure water, so in order to protect our own health, we need to pay attention to relevant problems when operating pure water equipment to truly produce good pure water. Next, let's take a look at the precautions for operating pure water equipment.
1. Prevent the filter material from entering the reverse osmosis device in advance. In order to prevent the filter from leaking sand and leaking activated carbon, we need to choose a suitable filter outlet device, and when choosing activated carbon, we must avoid powder removal during use.
2. In the large-scale pure water equipment with tap water as the water source, it is generally necessary to set up a separate water supply system to ensure the stable operation of the water supply system and reduce the instantaneous impact on the water supply network of the whole plant when the system is started.
3. When operating the pure water equipment, the compatibility between the used agent and the agent should also be considered, and the compatibility between the agent and the membrane material should also be considered. In order to prevent the equipment from scaling, the water inlet end of the equipment will generally consider putting scale inhibitor.
