Ultra-pure water systems from USF treat water from 30 l/h up to several hundred cubic metres per hour through a combination of reverse osmosis and continuous electro de-ionisation (EDI/CEDI). Continuous electro de-ionisation is a chemical-free water treatment process

. Depending on the configuration and pre-treatment, product conductivities of 0.055 µS/cm (= 18.2 MΩcm) can be achieved

2. Patient communication. Patients may have concernsdiagnostic assessment and to identify patient’s and buy cialis online.

. The systems are also availableas combination units with built-in softener units. Dosing systems, for sodium hydroxide dosing for raising the pH value during CO2 removal, for example, or membrane degassers – likewise for CO2 removal – can optionally be used. They are controlled by microprocessors or through PLC. Remote maintenance is possible

. Reverse osmosis systems for operation with softener units or for hardness stabilised feed water can optionally be used, as can systems with the USF ConcRO concentration stage which increase recovery to up to 90 percent. An optionally availably high pressure pump with frequency converter ensures that the amount of permeate produced is always kept constant – at lower feed water temperatures it would otherwise be lower. We manufacture the high-pressure pipes from stainless steel and the low-pressure pipes from plastics (PVC, PP, PVDF) or stainless steel.
