The requirements for titanium rod filter cartridge filtration mainly include the following aspects:
1、 Preparation before operation
Equipment inspection: Ensure that the titanium rod filter is on a stable and level workbench. Check if the center part of the titanium rod filter is correctly installed, ensuring that there are no loose or damaged areas.
Media preparation: Prepare the solution or liquid to be filtered and place it in the container to be filtered. Prepare filter paper or other filtering media to ensure that their size and shape match the titanium rod filter.
2、 Requirements during the operation process
Installation medium: Place the filter medium in the center of the titanium rod filter, ensuring that it is tightly fitted to the filter and has no leaks.
Start and adjust: Turn on the power switch and start the operation of the titanium rod filter. Adjust the operating parameters of the equipment, such as filtration speed and pressure, to adapt to the characteristics of the liquid to be filtered.
Filtering operation: Slowly pour the liquid to be filtered onto the top of the filter, allowing the liquid to gradually pass through the filtering medium and enter the container. Pay attention to controlling the filtration speed to avoid clogging or damage to the filter element caused by excessive speed.
Pressure control: The working pressure of the titanium rod filter element should not exceed its rated working pressure. During normal use, there should be a 3-5 minute low-pressure start-up time, and the relative pressure difference should be controlled below 0.5 MPa. Then, gradually adjust the working pressure to the required level (with a maximum pressure not exceeding 0.4 MPa). It is strictly prohibited to quickly increase the pressure by opening the valve in an instant to avoid damaging the filter element.
3、 Maintenance and cleaning
Avoid damage: Titanium filter cartridges are consumables, and although they are more durable than other filter elements, care should be taken not to scratch, touch, smash, or drop them during cleaning and disassembly to prevent human damage. It is strictly prohibited to apply force to the surface of the filter element with tools.
Regular cleaning:
After a certain period of operation, due to clogged filter elements, pressure may increase and flow rate may decrease. At this time, backwashing or backwashing regeneration is required.
The cleaning methods include backwashing with clean water, gas blowback, and soaking in chemical solutions (such as hydrochloric acid solution below 5%, sulfuric acid solution below 8%, or NaOH solution below 10%) before cleaning. The specific choice of cleaning method should be determined based on the properties of impurities in the filtrate.
Record and report: Record each filtering operation and create an operation report to ensure the traceability of the filtering process. Record and file the maintenance and repair status of the equipment for future reference.
4、 Other precautions
Avoid reverse filtration: In general, the filtrate is filtered from the outside to the inside of the filter cartridge, and reverse filtration is not recommended.
Material and compatibility: Titanium rod filter cartridge is suitable for filtering various acids, alkalis, salts, and organic solvents due to its excellent chemical stability and corrosion resistance. However, in specific situations, it is still necessary to pay attention to its compatibility with filtered liquids.
The requirements for titanium rod filter element filtration involve multiple aspects such as preparation before operation, control during operation, maintenance and cleaning, and safe operation. Following these requirements can ensure the normal operation of the titanium rod filter element and the stability of the filtration effect.
