Chapter 1. Introduction
1-1. Introduction
The aquaMAXTM Ultra 370 Series – Ultra Water Purification System produces ultra-pure water in resistivity
18.2 MΩcm and inorganics reduction up to 99.99%(TOC level to <10 ppb). The aquaMAX-Ultra can be easily
upgraded by adding a UV (Ultraviolet) lamp for low TOC level (< 5ppb), and a UF (Ultrafilter) for Pyrogen free
(lower than 0.06 Eu/ml). This system uses feedwater from R.O purification system and the produced ultrapure
water complies with specification by ASTM/CAP/NCCLS to ideal for reagent or standard preparation for HPLC,
IC, GC , AAS, ICP and ICP-MS applications.
The aquaMAXTM−Ultra 370 Series is very easy and simple to install, use and maintain. It looks as below.

1-2. Principals
1-2-1. ULTRA-Pack
The ULTRA-Pack is the heart of the aquaMAX-Ultra water system designed to provide water that is virtually
free of ions, residual chlorine and organic contamination. This special filter pack(Polypropylene shell) contains
specially prepared activated carbon, high mixed bed ion exchange resin and specialized organic scavenging
resin. This combination of high purified filter media makes the aquaMAX-Ultra system suitable for producing
water in the resistivity 18.2M·cm for extremely sensitive applications such as HPLC, Cell Culture, Semi-
Conductors, pharmaceutical and other laboratory uses.
The most important property is to remove ion from an ion exchange resin. Ion exchange capable materials
have week chemical combination. The materials have metathesis property a positive ion by a positive ion,
negative ion by a negative ion.
Ion exchange resin is divided into two classes, which is a cation exchange resin and a anion exchange resin.
(1) a positive ion (a cation) exchange resin
R-SO3H + Na+-> R-SO3Na + H+ (Strong Acid Cation exchange resin (SAC))
R-COOH + Na+-> R-COONa + H+ (Weak Acid Cation exchange resin (WAC))
(2) a negative ion (anion) exchange resin
RNOH + Cl--> RNCl + OH- (Strong Base Anion exchange resin (SBA ))
RNH3OH + Cl--> RNH3Cl + OH- (Weak Base Anion exchange resin (WBA))
A rule of ion exchange
(1) Generally in the case of low density, high atomic value ion is well exchange, absorption at normal
temperature aqueous solution
(2) In the case of same atomic value ion small semi-diameter advantageous at low density aqueous solution.

1-2-2. UV Sterilizing Filter
The UV lamp provides sterilization with ultraviolet rays. So, DNA and proteins absorb this ultraviolet rays to
be deactivated. It generates 185 and 254 nanometer wavelengths simultaneously to photo-oxidize organic
compounds and finally reduces TOC (Total Organic Carbon) level to 5 ppb.
1-2-3. UF Filter
UF filter, which is made from permeate hard and thin membrane, reduces almost of large molecular. It is
also effective to reduce most particles and bacteria.( Pyrogen* level to be 0.06 Eu/ml.).
* Pyrogen : As a kind of fragment on the cell wall of bacteria, this can be tested by lipopolysaccharides. When
it’s inserted in the body of Mammalian, it can cause fever inside of body and substantially effect to the bio-test.
For the use of medical-grade water(Type Ⅰ) to be applied to vaccines or drugs, it must be essentially
removed.

【OPERATE/STANDBY】
Press OPERATE/STANDBY key to start operating at the initial state(Ready mode). The system re- circulate
its inside on Recirculation state.
If there is no output water for more than1 min. in resistivity 18.2 MΩ·cm, recirculation is finished (to protect a
booster pump) and water quality is to be monitored. If the resistivity drops down under 10 MΩ·cm, the
system re-circulates to improve water quality.
Even though recirculation is stopped, LCD still displays「Operate」mode, if the resistivity is higher than
13MΩ·cm, production is available any time by pressing PRODUCTION key.
Pressing OPERATE/STANDBY key during operation gets the mode back to「Standby」mode.
【PRODUCTION/RECIRCULATION】
If the resistivity is higher than 13M, production is available any time by pressing PRODUCTION key.
While production, if you press PRODUCTION/RECIRCULATION key, it stops producing and get back to
Recirculation state
