| Pumped solution is circulated at a high rate from your process tank or reservoir up to the ET-II or ET-III and is drained back by gravity to your tank. In the evaporative, the solution is sprayed onto 700 or 1,000 square feet of evaporative panels to humidify the blower air that is forced through these panels. The humid air is then ducted to the outdoors. Het for evaporation is taken from the solution pumped through the evaporator(about 9,000 BTU per gallon of evaporation. | The "triple-effect", proprietary
mist eliminator reduces any droplet emissions to a very low level. An
optional Airscrubber™ can be installed inside the EVAPORATIVE TANK™
at any time to further reduce emissions to meet most stringent
regulations.
The ET-III-W or the ET-II-W depends on a high flow rate and large solution drops suspended in the air stream for its extensive evaporative surface. The 1/2" passages in the spray nozzles make the ET-III-W ideal for waste minimization. The ET-II-W is a smaller version of the ET-III-W and uses a flow rate of 20 to 25gpm. |
| The chart at the right is
based on 0% relative humidity. As relative humidity increases, the
evaporation rate of solution at ambient temperature decreases. As ambient
temperature increases, the effect of relative humidity on the evaporation
rate decreases. Temperature does not dictate evaporation rate...BTU input
does (9,000 BTU's or 2.6 KWH per gallon). This graph shows the maximum
rates you can expect.

The EVAPORATIVE TANK ™is available in four models;
The ET-II and the ET-III The ET-II-W and ET-II-W are ideally suited for dewatering spent solutions or
wastewaters that may have a high solids content.
are designed to recover chemicals (dragout) from rinse water.
