EDI now with filtration

The Septron Bio-Safe from Christ Water Technology Group is said to be the world¡¯s first electro-deionisation (EDI) module with an integrated membrane filtration stage. It is based on the company¡¯s proven and patented spiral-wound EDI technology, with an additional membrane stage to remove particles and bacteria. Combined with an upstream reverse osmosis (RO) stage, Septron Bio-Safe can produce Highly Purified Water (HPW) with bacterial counts of ¡Ü10 CFU/100 ml, with no additional ultrafiltration required. Septron Bio-Safe can easily be retrofitted to existing Osmotron systems, considerably improving the microbiological safety of existing pure water systems. Septron Bio-Safe is available in cold-water and hot-water versions, and in various sizes covering the throughput range 500¨C3,000 l/h. The cold-water version is particularly suitable for pharmaceutical applications, where high efficiency and low costs are important. In the hot-water version the complete system, including the preceding process steps, can be sanitized at temperatures above 80 ¡ãC, resulting in even better system safety.
