Efficient evaporation system for mine wastewater

the-i-vap-500-is-a-water-evaporation-system-for-mine-wastewaterThe need for an environmentally-safe evaporation system to reduce excess wastewater at mines has been identified and addressed by I-CAT Water Solutions.

They have developmed the I-VAP 500 Evaporation Cannon, which ensures that wastewater from mine sites does not enter the general environment and thereby contaminating water further downstream.

“A particular benefit of the I-VAP 500 is its low energy-use to evaporation ratio,” said Morne Van Wyk, Technical Manager, I-CAT.

The cannon produces a large spray pattern that allows for a longer float time, thereby increasing the evaporation rate. The evaporation rate is 60% to 65%, depending on the ambient weather conditions. The cannon is capable of handling 500 m3 per 12-hour per day, covering about 32 000 m2, with an automatic oscillation option of up to 359°.

It works by atomising the water through 38 nozzles, which are available in PVC, stainless steel, brass or nylon, depending on the application and the  customer requirements.

The control panel itself is secured in a stainless steel cabinet, with the cannon itself constructed from composite materials in order to prevent rust, as well as making it lightweight, durable and mobile.

I-CAT Water Solutions recommend that the nozzles be inspected quarterly if potable water is used.
