SDI API Tester

Pollution Index (SDI) value is the measured water reverse osmosis system is one important indicator. Effluent treatment system to test whether the principal means of reverse osmosis water requirements. It is the size of the operational life of the RO is essential. Operational use: 1, the inlet valve of the measuring instrument (2) closed.

2, the measuring instrument connection screw (1) installed in the location determination. 3, inlet valve opening to avoid (2), the regulator pressure transferred to 0.21Mpa. 4, close the water inlet valve (2). 5, remove the diaphragm. (Taken diaphragm Methods: fast access valve (5) pushed up the outer trap, film box automatically fall off.

Note: the demolition of a good time to bring it diaphragm, diaphragm off to prevent damage to the film falling on the ground when the box.) diaphragm cover (7), the compression screw (6) screw on the appropriate procedures. 7, the film cassette was inserted into fast access valve (5).

8, open the inlet valve (2) out of the bubble membrane attachment box, close the water inlet valve (2), tighten the clamping screw (6). 9, open the inlet valve, when the simultaneous determination of the beginning of 500ml water filtration time t1 be allowed to continue filtering.

10, determination of 5,10, and 15 minutes 500ml water filtration time (Note: Throughout the test period, pressure must be maintained at 0.21 ± 0.07Mpa). 11, measured water temperature (Note: During the measurement period, the water temperature must be maintained at ± 1 ° C within the range).
