Mechanical Evaporators FAQ Mechanically - Enhanced Evaporation The Minetek Evaporators employ a process known as Mechanically Enhanced Evaporation (MEE). Evaporation is enhanced by the Minetek Evaporator primarily by two means. The feed water is delivered at high pressure to a series of fracturing nozzles. This produces millions of droplets per second, resulting in a massive increase in surface area, much greater than could be practically achieved by an evaporation pond. The Minetek Evaporator also employs a fan to increase the wind speed to more than 150 km/h, thus increasing the Evaporation Rate well beyond that of the ambient Pan Evaporation Rate (PER) (to which evaporation ponds are limited). As you can appreciate, we are simply taking a natural process (solar evaporation from the sun) and mechanically enhancing it through the use of the Mechanical Minetek evaporator.
The Minetek Evaporator The Minetek evaporation system functions by discharging water through a unique water fracturing nozzle. This nozzle is designed to achieve the correct water molecule size by fracturing, to maximize performance via droplet reduction and direct water fragmentation. The water is then injected into a high volume/high-velocity air stream to propel it into the atmosphere. Enhancing hang time and exposure to external- ambient elements. This is a continual process with the ambient air being replenished via a high-performance vane blower unit within the Evaporator. Drawing air from fresh ambient surroundings to maintain and achieve the highest possible evaporation.
Evaporation Efficiency Minetek undertakes specific evaporation efficiency modelling for each client we work with. This is based on weather data inputs such as humidity, rainfall, elevation, wind, TDS and temperature. This model enables us to understand the evaporation rates we will be able to achieve over 12 months in any specific climate. Based on the outcome of this study and the volume of water that is required to be evaporated, Minetek is able to propose and configure a solution to meet the specific requirements. The Minetek Evaporators are engineered to achieve an evaporation efficiency of approximately 50% in a single pass, e.g., if 1000L of water is expelled into the air, 500L will be lost as a water vapor, while the remaining 500L of non-evaporated water returns to the feed pond as shown in the diagram below.
