Precision filters, also called security filters, are generally installed in front of pressure vessels to remove fine particles above turbidity to meet the requirements for incoming water in subsequent processes. Sometimes it is also set at the end of the entire water treatment system to prevent fine particles (such as broken resin) from entering the finished water.
In the process flow of pure water equipment, security filters are generally used in front of the R membrane as a precision filter. The main function is to intercept larger particles in the raw water. Because the thickness of the reverse osmosis membrane in pure water equipment is about 100%, larger particles in the raw water can easily scratch the desalination epidermal layer on the surface of the reverse osmosis membrane after being accelerated by the high-pressure pump. It may break down the reverse osmosis membrane module. Therefore, a precision filter must be installed in front of the reverse osmosis pure water equipment to ensure that the reverse osmosis membrane is not scratched by large suspended particles. Another function is to pass through the filter element and also allow the reducing agent to pass through. Mix the reaction thoroughly to neutralize the oxidizing agent.
2. Performance characteristics of security filters in pure water equipment
High filtration precision, uniform filter element pore size
Small filtration resistance, large flux, strong dirt interception ability, and long service life.
The filter element material has high cleanliness and no pollution to the filter medium.
Resistant to acid, alkali and other chemical solvents.
High strength, high temperature resistance, and the filter element is not easily deformed.
Inexpensive, low operating costs, easy to clean, and the filter element can be replaced.
In addition, the security filter in pure water equipment can also effectively remove suspended solids, rust, etc. in the liquid and can withstand high filtration pressure. The unique deep mesh structure makes the filter element have a high dirt-holding capacity. The filter element can It is made of a variety of materials to meet the needs of various fluid filtrations. It has a small appearance, large filtering area, low resistance and long service life.
3. Cleaning method of security filter in pure water equipment
The inlet and outlet water of the security filter needs to be equipped with a pressure gauge. When the pressure difference between the inlet and outlet water reaches the limit value during operation, the filter element should be replaced in time. Due to the low cleaning and recovery efficiency of the filter element, Water Treatment Home Network recommends the use of disposable filter elements. The detailed cleaning method is as follows:
. If the system is dirty when you start testing, you can open the upper flange of the precision laser water filter after flowing water two or three times, and gently take out the water filter element
.After taking out the filter element, immerse it in clean water and use a soft brush to clean the outside of the filter element. Do not hit the filter element with hard objects during cleaning
3. Open the filter, clean and discard the dirt inside the filter cartridge
. Place the filter element gently into the filter cartridge, put the gasket and flange cover in place, and tighten the bolts. After normal operation, according to the water quality, clean the filter element regularly according to the above procedures.
