Filtration is an essential process in the pharmaceutical industry. The major purpose of the process is to remove all the impurities from the product. The filtration process ensures that the final product meets the standard and specific quality standards. The pharmaceutical sector employs different types of filtration systems, each of which has its own specifications and advantages.

One of the highly used filtration technologies in the pharmaceutical manufacturing process is candle filters. Candle filters are an alternative filtration method for removing fine particles. It is made of solid porous ceramic or metal barriers that suspend like a candle in the flow stream.

In this blog, let’s understand the candle filters in pharmaceutical filtration as well as their applications, benefits and selection in detail.

A] What Are Candle Filters?

Candle filters are used to separate solid particles from liquids. These filters are mainly used in the pharmaceutical industry for various industrial applications such as wastewater treatment and chemical processing. The Porous Plastic Filters are designed to be cylindrical and contain a porous material.

The candle filter consists of three major components, i.e., a single-piece dip pipe, filter sock, and perforated core, with external support tie rods. The candle-shaped cylindrical filter elements are arranged vertically.

In the pharmaceutical process, this filter offers an efficient and cost-effective way to improve the overall product quality and reduce waste generation.

B] Application Of Candle Filters In The Pharmaceutical Industry

1. Waste Management

The candle filter for pharmaceuticals plays an active role in the waste management process. This filter type is specifically engineered to capture particles in various sizes. Moreover, it will provide higher efficiency and precision in the overall filtration process.

The filter fibres will act as a protective barrier to trap particles in the layer. These porous plastic Candle Filters are used in the pharmaceutical manufacturing processes because they offer an effective way to filter out contaminants while letting the main product flow in the system.

2. Water Purification

Candle filters will be used to purify water. It can effectively remove harmful contaminants from the water sources, such as microbes, metal compounds and other pollutants. The filter is purified using the “reverse osmosis” process. It is a great way to purify water without the use of harsh chemicals which are harmful to the environment.

The filters will recover pharmaceutical products in a cost-effective way and also enhance purity and quality. In addition, it will reduce overall waste generation. The filter is available in a variety of sizes and shapes to trap liquid droplets, aerosols and dust particles without impacting the ability of the product to flow through the system.

3. Better Recovery Rate

The candle filter will be used as an alternative to the downstream centrifuge to improve the product recovery rate. Centrifuges can effectively separate liquids from solids. This method is effective, but it can produce a huge amount of waste that has to be disposed of.

With the use of candle filters downstream of centrifuges, you will notice a significant improvement in the product recovery rates. It can capture smaller particles, which are usually undetected. It further results in higher yielding and reduces resource and material loss.

C] Benefits Of Filter Candles

• Efficient Particle Removal

Filter candles will effectively capture smaller particles and impurities from fluids. The filter results in high-quality filtration and also deeply cleans processed fluids. With its specialised filter media and micron ratings, this filtration technology is known for its precise filtering ability, which is custom-made to meet specific application needs.

• Reliable Filtration Performance

The filter candles offer reliable and consistent filtration performance with their longer operational lifespan. It comes with a higher dirt-holding capacity that results in longer filtration without any compromise to its quality and efficiency. With regular filter replacement, the candles prevent pressure drop issues and offer optimal performance.

• Ease of Installation and Maintenance

Filter candles are quite easy to install and replace. It can perfectly fit into standard filter housings. Also, it can be easily replaced without the necessity of specifically engineered tools and complex procedures. This will further simplify the overall process and improve the efficiency of the filtrating operation. In addition, the filters will reduce downtime.

• Versatility and Compatibility

The candle filters are easily compatible with different filtration systems and different filter housings. It facilitates adaptability and flexibility in different applications. Further, the filters can be customised with specific filter sizes, media, and end-cap configurations to cater to various requirements in the pharmaceutical industry.

• Cost-Effective Solution

Filter candles are available in cost-effective price ranges.  The tools are known for their efficacy, easy replacement and durability. It will reduce your maintenance costs by protecting downstream equipment. Moreover, it will reduce product contamination risk. Overall, it will optimise operational efficiency and reduce overhead costs.

D] Choosing The Right Candle Filters

For pharmaceutical industrial purposes, you must go for high filler clarity filters such as candle fillers for enhanced polishing. You have to check out the quality of the material to reduce the potential risk of environmental hazards. Also, make sure the filter offers a secure mechanism for consistent discharging. Also, go for the right size, shape, and configuration to fit your filtration system specifically. Overall, ensure that it meets your industrial application in order to improve your product quality and recovery rate.
