| The value of pollution index (SDI ) determines one
of the important indexes of entering water of the counter-infiltration
system. Examine process system is it is it permeate through
main means that ink require instead to up to to surface
in advance. Its size is essential to life-span of counter-infiltration
operation. |
1, join the screw
2, enter the water polo valve
3, the regulating valve of the pressure
4, the manometer
5, connect the valve quickly
6, compress tightly the screw
7, membrane box top cover
8, ask under the membrane box
9, the water outlet appears |

1, The water polo valve (2 ) is closed to enter this measure apparatus.
2, Join installation of screw (1 ) of the measure apparatus and locate.
3, Open into the water polo valve (2 ), adjust the pressure of the
voltage regulator to 207kpa.
4, Close into the water polo valve (2 ).
5, Take down the membrane box . (Fetch the membrane box method : The
other snare that will connect the valve (5 ) quickly is pushed upwards,
the membrane box comes off automatically. Notice: Hold the membrane
box properly while dismantling , prevent the membrane box from damaging
the membrane box losing while coming off. )
6, Open membrane box after taking down , take out membrane box "
O " type enclose , 0. 45|ì strain membrane put membrane box strain
membrane support board , enclose and put the normal position into
" O " type and then, cover oneself up with the membrane
box top cover (7 ) , will compress tightly the screw (6 ) to twist
in the proper degree.
7, Insert the membrane box in and connect the valve (5 ) quickly .
8, Is it enter water polo valve (2 ) is it strain membrane box carry
bubbles secretly , close into the water polo valve (2 ) to evict from
to open, is it compress tightly screw
9 , open enter water polo valve to tighten , filter 500ml water sample
necessary t1 , he of time , let it is it filter to continue at the
beginning of determining at the same time.
10, Determine for 5 , 10 , and time to filter the water sample of
500ML in 15 minutes (notice: During testing entirely, the pressure
must be in 207?à 7kpa).
11, Determine the temperature (notice: Among examining entirely fixedly,
the temperature must keep within change of a degrees Centigrade range).

P30 enters the index of stopping up under water pressure strength
in 207kpa;
Tt total examining the time (divides ) is usually T15, P30 at this
moment <75%, otherwise test T10 or T5, P30 that makes at this moment
Collect the time that the water sample of 500ml needs when <75%
T1 is initial (second);
T2 collect 500ml water sample necessary time behind T1 (usually T15
) (second). |
