Ultrapure water system

Wednesday, 12 March, 2008 | Supplied by: Bio-Strategy - Part of DKSH Group


Ultra Clear TWF systems from SG Water are equipped with all the necessary components to produce reagent-grade water directly from municipal tap water. The built-in reverse osmosis system has a recovery rate of <30% to conserve water.

SG created the compact Ultra Clear TWF systems with all the required technical features to produce purified and ultrapure water with low running costs.

The downstream deionisation module polishes the RO product water before delivery to the storage tank. Water going to storage has a quality of <2 µS/cm. The ultrapure TWF system has a dispense rate of up to 1.8 L/min with a water quality of 18.2 MW-cm and a TOC level of <1 ppb. The system meets all reagent-grade water quality standards including ASTM Type 1, NCCLS Type 1 and ISO Type 1.

Options include ultrafiltration, UV-oxidisation and TOC-monitoring with intensity measurement.

Pre-treatment, reverse osmosis module, deionisation cartridge, storage tank, UV-oxidisation chamber, polisher, ultrafilter and sterile filter are all integrated into one system.

An automatic flushing mechanism for the ultrafilter extends the service life. Cartridge changes are very simple and fast due to quick and easy access to the replacement parts. Other advantages include the possibility to draw pure water via a tap on the optional storage tank, as well as connecting the system directly to an instrument or glass washer, and system running costs are low.

The units can either be bench or wall mounted. A flexible dispenser enables the user to remotely dispense water wherever it is needed. Pure water dispensing is made easy by simply activating the valve lever. A continuous flow of pure water is accomplished by simply placing the dispenser lever in an upright position.

SG Ultra Clear TWF systems are available with special features such as volume control dispensing, a 24 h circulation mode with an extremely low noise level of <40 dBA and an integrated RS232 interface for data recording. Variable length hoses for the remote dispenser are also available.
