Parker Hannifin, a US company specialising in motion and control technologies, has introduced a new filter solution for bottled water manufacturers.

Parker Bioscience Filtration, a division of Parker Hannifin, launched the Bevpor Caustic Stable filter, designed to ensure microbiological safety in bottled water while withstanding high concentrations of sodium hydroxide – known as caustic – found in some clean in place (CIP) processes.

The Bevpor Caustic Stable filter is intended for bottled water manufacturers who use higher concentrations (typically over 2%) of sodium hydroxide in their CIP processes. These processes are used to regenerate filters involved in batch processing and packaging beverages. Aggressive CIP methods may be required to break down blockages or fouling materials that cannot be removed with standard sodium hydroxide concentrations.

Standard membrane filters can be damaged by high concentrations of sodium hydroxide, compromising filter integrity, reducing production efficiency and increasing operational costs, while risking product quality and safety.

According to the company, the Bevpor Caustic Stable filter can withstand these aggressive CIP processes, offering high throughput and microbial stability, making it a cost-effective and efficient solution for bottled water manufacturers.

The filter uses a high-performance, asymmetric PES membrane that ensures complete sterility, as per ASTM F838-20, and is designed for final water stabilisation before bottling or canning.

Mark Richardson, processing product manager at Parker Bioscience Filtration, said: “Born from our close relationship with the bottled water industry and engineered with our problem-solving approach, Bevpor Caustic Stable is an important addition to our Bevpor product portfolio".

“It will enable manufacturers which employ aggressive CIP regimes to benefit from the increased process control and operational efficiency offered by our Bevpor range, and help them to protect their beverages from contamination prior to bottling.”
