The core application of cover filters is high-precision solid-liquid separation, which is widely used in industries that require high water purity or material clarity due to its filtration characteristics that can form a "cover film".
1、 Power industry
Used for boiler feedwater treatment in thermal and nuclear power plants, removing suspended solids and colloids from water, ensuring the purity of boiler feedwater, and avoiding pipeline scaling and corrosion.
Adapt to the condensate polishing system, filter impurities such as iron and copper oxides in the condensate, and maintain the efficient and stable operation of equipment such as steam turbines.
2、 Chemical and petrochemical industry
The filtration and purification of raw material liquids and intermediate products in chemical production, such as the clarification of acid-base solutions, solvents, and catalyst suspensions, can improve product purity.
The filtration of lubricating oil, diesel and other oil products in the petrochemical industry removes mechanical impurities and gum from the oil, protecting subsequent equipment such as pumps and heat exchangers.
3、 Water treatment industry
Deep treatment of municipal sewage removes suspended solids and phosphorus after secondary treatment, providing assurance for the reuse of reclaimed water or compliance with discharge standards.
Industrial wastewater treatment (such as printing and dyeing, papermaking wastewater) filters and recovers useful substances from wastewater, while reducing effluent turbidity to meet environmental protection requirements.
4、 Electronics and Semiconductor Industry
Terminal filtration during the preparation of ultrapure water removes trace suspended solids and particulate matter from the water, ensuring the water quality requirements for electronic components and semiconductor chip production (resistivity ≥ 18M Ω· cm).
Filtering of electronic chemicals such as photoresist and developer to avoid impurities affecting chip lithography accuracy and product yield.
5、 Food and Beverage Industry
Clarify and filter fruit juice, beer, and wine to remove impurities such as fruit pulp and yeast, improve beverage transparency and taste, and extend shelf life.
Filtering dairy products (such as milk and yogurt) to remove protein clots and microbial carriers, ensuring food hygiene and safety.
6、 Pharmaceutical and Biological Industry
The filtration and purification of medicinal and biological agents remove impurities and bacteria from the medicinal solution, meeting the GMP standards for pharmaceutical production.
Fermentation broth filtration, separation of microorganisms, mycelium, etc., extraction of target products (such as antibiotics, enzyme preparations), ensuring product purity.
