How RKSfluid Candle Filters Empower Chemical, Pharmaceutical, and Food Industries

In modern industrial processes, reliable filtration is critical for both product quality and operational efficiency. Traditional filtration systems often struggle to meet the precision, flexibility, and automation needs of high-demand industries.

RKSfluid Candle Filter Systems provide versatile solutions that address these challenges, delivering precise, automated, and energy-efficient filtration across multiple sectors, including chemicals, pharmaceuticals, food & beverage, and new energy.

1. Chemical Industry – Maximizing Catalyst Recovery

During PTA (Purified Terephthalic Acid) production, traditional filter presses often fail to recover catalysts smaller than 5 μm, resulting in material loss and increased costs.
RKSfluid’s solution uses a dual-stage filtration approach:

• Front-end 5 μm ceramic filter
• Rear-end 0.5 μm sintered metal candle filter

This configuration achieves a 99.2% catalyst recovery rate, saving companies over USD 400,000 per year in raw materials.
By combining high-precision filtration with automatic backflushing and modular candle arrangements, chemical plants can maintain continuous operations while reducing downtime for maintenance.

2. Pharmaceutical Industry – Ensuring Sterile Filtration

Pharmaceutical manufacturing requires sterility and process traceability, particularly for antibiotic fermentation liquids.
RKSfluid candle filters incorporate:

• Steam-In-Place (SIP) sterilization capability
• 316L sanitary-grade construction
• High-temperature tolerance up to 121°C

This ensures compliance with FDA and cGMP standards, allowing the filters to operate safely in sterile production lines while minimizing contamination risks.

3. Food & Beverage Industry – Clarity, Safety, and Nutrition

In juice clarification and beverage processing, filters must remove particles without compromising nutritional content.
RKSfluid candle filters use 0.2 μm PTFE membranes that efficiently eliminate:

• Fruit pulp and sediment
• Yeast and microbial residues
• Pesticide traces

At the same time, essential nutrients such as Vitamin C are preserved.
Field tests from a leading juice manufacturer demonstrated:

• Turbidity reduction from 12 NTU to 0.5 NTU
• Shelf life extended by 30%

Our candle filter systems are designed for high-precision, automated, and energy-efficient performance — helping clients enhance product quality, extend equipment lifespan, and reduce operating costs.
