Precautions for use:

1. The supply of porous sintered titanium plates is consumable. While they are more durable than other filter elements, caution should be exercised during the cleaning and disassembly process to prevent any scratches, contact, or impact that may cause damage. It is strictly prohibited to use tools to apply force to the surface of the filter element.

2. Under normal circumstances, the filtration process should proceed from the outside to the inside of the filter element. Reverse filtration is not recommended.

3. During the filtration process, gradually increase the pressure to reach the required working pressure. It is strictly prohibited to rapidly open the valve for quick pressurization.

4. The maximum working pressure should not exceed 2MPa. If the filtration efficiency drops below 50%, it should be promptly backflushed with clean air or a clean liquid.

5. When backflushing the titanium filter element, it is generally recommended to perform an initial backflush with pure gas. The backflushing pressure should be 1.2-1.5 times the working pressure, and each backflushing should last for 3-5 seconds. Afterward, repeat the backflushing process 4-6 times using a cleaning solution for a duration of 3-5 minutes, with 2-3 repetitions.

The cleaning method:

1. According to the pollution situation and the chemical properties of the pollutants, combined with the physical and chemical properties of titanium metal, various methods can be used for regeneration and cleaning. These include physical methods such as clean liquid backflushing, clean gas backflushing, and ultrasonic cleaning. Chemical methods involve the use of dilute acid, dilute alkali, oxidants, surfactants, enzymes, and other cleaning agents. These methods can be used interchangeably depending on the specific requirements.

2. In the pharmaceutical and chemical fields where decarbonization and filtration are required, a combination of backflushing, backwashing, and ultrasonic cleaning methods is often employed to achieve optimal results.

3. In the water production industry, where water-insoluble salts and oxides are commonly found on the filter element's surface, a cleaning effect can be achieved without ultrasonic cleaning by soaking the element in a 5% acid solution.

4. When filtering raw liquids, the cleaning method should be determined based on the chemical properties of the pollutants:

(1) Alkaline washing: Soak the filter element in a 3-5% solution of analytically pure sodium hydroxide at a temperature of approximately 40 degrees Celsius for 30-60 minutes. Ultrasonic cleaning machines are recommended for best results. Once the element has soaked, rinse both the interior and exterior with filtered deionized water or water for injection until the water is neutral, then take the conductivity reading. Dry the element using pure air with a pressure of ≥0.4MPa.

(2) Pickling: Soak the filter element in a 5% acid solution at a temperature of around 40 degrees Celsius for more than 8 hours. Ultrasonic cleaners are recommended. Once the element has soaked, rinse the interior and outside with filtered deionized water or water for injection until the element is neutral, then measure the lateral conductivity. Dry the element using pure air with a pressure of ≥0.4MPa.

(3) Organic pollutants can be cleaned using surfactants, while enzyme-based cleaning is more effective for cell debris pollution systems. In the case of food and beverages, high-concentration citric acid can be used for cleaning.

(4) These methods can be used individually or in alternation. If possible, combining them with an ultrasonic cleaner is recommended for optimal cleaning.
