Mechanical evaporation

Mechanical Evaporation

Mechanical evaporation is a process that uses mechanical energy to remove water from a solution. This can be done by using a centrifuge, which spins the solution at high speeds to force the water out, or by using a vacuum, which removes the air from the solution, causing the water to evaporate. Mechanical evaporation is often used to concentrate solutions, such as salt water, that would otherwise take a long time to evaporate naturally. It can also be used to remove impurities from solutions, as the impurities are left behind when the water is removed. Mechanical evaporation is a quick and efficient way to remove water from solutions, and it can be used in a variety of industries, such as food and beverage production, pharmaceuticals, and chemical manufacturing.

MINETEK's mechanical evaporators are uniquely designed to process a vast range of varying water qualities. The design of the evaporator is based on fan engineering and airflow principles and it was created specifically to evaporate wastewater in an efficient, cost-effective and sustainable way.

One of the key advantages of our evaporation units is the ability to evaporate water with a pH level ranging from 2.2 to 12. This includes acid water, caustic water, high TDS and TSS water. Depending on your climate, our systems have the potential to evaporate up to 50% of spray volume as pure water vapour, with the remaining volume of non-evaporated droplets returning to the feed or tailings pond. Consequently, using a MINETEK water evaporator could be an extremely effective way of managing wastewater while also being cost and environmentally friendly.

Our patented nozzles are specifically designed and engineered to process solids of up to 4.0mm in diameter. This unique design is a critical factor in longevity, durability, and ultimately, the performance of the units. With over 300 projects completed across the globe, MINETEK has built a name by delivering the world’s largest and most cost-effective water evaporator system. Offering both land-based and floating evaporation solutions. 

Mechanical Evaporation

This technology allows for the environmentally friendly disposal of large volumes of wastewater generated from various industries. Moreover, it does so without the release of any pollutants into the atmosphere. The system works by first separating the wastewater into two streams: one containing suspended solids and the other containing dissolved solids. The stream containing suspended solids is then processed through our patented nozzle array. This breaks down the solids into smaller particles that are then easily evaporated. The stream containing dissolved solids is then passed through a series of filters that remove impurities before it is also evaporated. The result is clean water vapour that is discharged into the atmosphere, leaving behind only a small amount of residue.

This innovative technology has revolutionized the way industries deal with their wastewater, and with over 300 systems installed worldwide, MINETEK WATER is leading the way in sustainable wastewater management solutions. If you are looking for an effective and environmentally friendly way to dispose of your wastewater.

Northern Goldfields Mining Manager

Kipoi have successfully utilized MINETEK WATER evaporators on our process water pond to remove mine water and has contributed to help with our water balance. We are currently in the process of moving these units to where the catchment area is larger giving us better utilization of the evaporators.

Tiger Resources Process Superintendent

MINETEK understand our business, and our requirements, and always display a solid commitment to meeting our goals. We enjoy an open and honest business relationship, and we consider ours to be a lifelong partnership.

Liebherr Australia Mining Manager

The relatively small fans allowed us to utilise our existing bulkhead, where we were severely limited by space, which allowed us to use our existing infrastructure and dramatically reduce downtime in the mine during the change out. The installation was completed safely... and allows us to scale our ventilation flow with their pressure on demand system to suit our production profile.

Saracen Thunderbox Underground Manager

We are always looking at new innovations and technologies that will benefit both us and our clients. Minetek has been able to display that with the use of their modern ventilation technology, where we can look to see production increases through faster re-entry times and reduced capital costs in the total life of the development, delivering value to both us and Mincor.
