Bioscience and Water Filtration Division - Point of Entry Clarification

Point of Entry Clarification

Water entering a bottling facility directly from a source is sometimes referred to as point-of-entry (POE) and will require clarification filtration to remove any insoluble contaminants such as sand, silt or debris before entering intermediate storage. To be considered a 'Natural Mineral Water' then this is the only step permitted within Europe, any further filtration would alter the chemical and biological makeup of the product, which then may no longer be considered a Natural Mineral Water. 

Typically the filtration employed for this requirement will be designed to handle a high and variable particle loading. Carefully selected retention and construction of the filter at this stage in the process will greatly influence the performance of the filtration processes used downstream and will improve overall process efficiency.

Products for Clarification
