Tomar TV-6000, Owner'S Manual

After the system has run for a few minutes turn the BRINE valve clockwise until the system pres-
sure gauge reads 150 psi (10.3 bar) or a product flow rate of 4 GPM (15 l/min) for the TV-6000 or 5.5
GPM (21 l/min) for the TV-8000.  At this point the RECIRC vallve can be opened and the BRINE valve
closed in coordination so that the VESSEL IN pressure  stays close to the 150 psi point..  The
BRINE flow should not be allowed to drop below 2 GPM for the TV-6000 and 3 GPM for the TV-8000.
If the feed water mineral content is very high the BRINE flow rates may need to be increased some-
what to minimize membrane fouling.  For very high feed water TDS an antiscalant injection system
is recomended. Fully open the concentrate recirculation valve (if system is equipped) by turning the
knob CCW.

Allow  the system to flush with all water discharged to drain.  Periodically check for leaks and check
the system vessel-in pressure gauge.  It is likely that the pressure will drift from 150 psi (10.3 bar)
during the flushing; if it does, adjust the concentrate valve to correct the pressure back to the original
setting. 

 DO NOT LET SYSTEM PRESSURE RISE ABOVE 200 PSI (13.8 bar). 

 When pressure,

flows and TDS have stabilized turn the unit off, connect the product line and re-start the unit.

5.3 PERFORMANCE VERIFICATION

Factory test data is supplied with the system at the end of this manual.  This data reflects unit
performance with municipal water available at the factory.  To ensure optimum performance, on-site
data should be taken and compared to the factory test data.  This data should be taken after the
system has been flushed for one hour.  Some deviations may be seen due to differences in feed
water TDS and temperature between the site and factory.  If you have already connected the product
line to the tank, you will need to disconnect it ahead of the post carbon filter (if one is installed) to
take product samples.

5.3.1 FLOW TESTS

This testing is needed only if the unit is not equipped with the full flow meter complement.  Deter-
mine the flow rates for both product and concentrate (brine).  Put the product line into a graduated
container and measure the volume of water that flows into it in one minute.  Repeat the process with
the concentrate (labeled BRINE) line.  These values should be in either gpm or ml/min.

5.3.2 RECOVERY

Compute the recovery according to the following formulas: Recovery = Qp/Qs where Qs=Qb+Qp,
as discussed in 3.2.2 OPERATING PARAMETERS.

5.3.3 REJECTION

This testing is needed only if the unit is not equipped with the standard TDS meter.  Using a conduc-
tivity meter (TDS meter) measure the TDS in both the feed water and the product water.  Calculate
percent rejection using the formula below:

(Feed TDS-Product TDS) / (Feed TDS)* 100 = % Rejection

Rejection should be 96% or better.  For example, where the feed TDS is 600 and the product TDS is
24, the percent rejection is:

(600-24)/ 600*100 = 96%.
