Demand for porous materials used in liquid filtration continues to grow. Pleated cartridges treat fluid streams utilizing many materials to achieve the optimal combination of efficiency, life and flux. With growth in demand comes growth in regulatory complexity. At the wellhead, waste water can be discharged – but determining the appropriate standards to follow is difficult. Municipalities can follow direct-to-potable reuse (“DPR”) guidance – but these are new, complex rules. Producers of food, beverages and pharmaceuticals can use many different liquid quality standards on a single product. These diverse demands are made more complex when the quality of porous materials enables the safety of downstream processes and product. Adopting a common, systematic approach to these questions lowers the cost of compliance and improves the performance of the entire filtration industry.

H&V has adopted Hazard Analysis Critical Control Point (“HACCP” – pronounced ‘Hass-sip’) as its quality management system and business process for analyzing product safety, product suitability, and plant capability in the regulated end markets which dominate liquid filtration. Creating a HACCP plan for products used in liquid filtration gives porous material producers and users a mutual framework to make statements about many questions that are crucial to end customers and regulators, including...
