Description
Elgastat water purifier option 3b
Elgastat Option 3: Purified and sterilised by reverse osmosis, deionisation and ultra-violet irradiation) for preparation of all reagents. Water can be highly variable and local conditions can influence any number of processes or procedure. Replacement of tap water washes with purified water can be helpful if local water quality is poor.
This unit is an ideal complement in any laboratory, school, or university which requires a high-quality water supply at a minimal cost.
The unit is designed to operate from a good quality potable water supply and produces approximately purified water which is further purified and circulated through a treated water reservoir. The water is processed and treated by the Elgastat option 3 unit as follows:
• Potable water enters through a strainer and inlet solenoid valve at either regulated mains water pressure, or is pumped by means of a feedwater pump (optional), and passes through the pre-treatment cartridge. The pre-treatment cartridge has been designed to protect the reverse osmosis cartridges from particulate/colloidal matter and excessive free chlorine, which may be present in the incoming feedwater.
• The permeate water then passes the sanitization port and through reverse osmosis cartridges, set up in series, which split the flow into permeate and concentrate streams. The permeate water is further purified whilst the waste concentrate stream is passed to drain. • The permeate water passes through a water quality sensor which measures the conductivity of the water.
• The permeate water is drawn into the main re-circulation stream by the re-circulation pump together with water from the reservoir and passes through the re-circulation purification loop.
• This water is pumped directly through the UV chamber where it is exposed to intense UV radiation to provide continuous bacterial control by photo oxidation and to promote the cleavage of organic molecules.
• The partially purified water then passes through the ion exchange cartridge which removes dissolved ionic impurities from the permeate water.
• Finally, the water is passed through;
• Water quality sensor, which measures the resistivity of the water.
• Temperature sensor which provides accurate temperature measurement.
• The deionised water is either dispensed through a dispenser tap.
• During periods of non-use the unit will automatically operate in intermittent re-circulation mode to maintain water purity with maximum efficiency.
