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. Minetek's Model 600/300 Evaporator can process up to 2,250 litres per minute, equating to 135,000 litres per day, resulting in 3,240,000 litres of wastewater processed over 24 hours. Assuming an average evaporation efficiency of 50%, Minetek's Model 600/300 can evaporate up to 1,620,000 litres of wastewater per day. 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.

MINETEK's installations have been very successful and prompted the contracting of MINETEK to conduct a full mobile fleet and fixed plant noise monitoring assessment at the Acland mine site.

New Hope Group Project Superintendent

MINETEK will continue to be a favoured technical resource and supplier to the New Hope Group and are recommended as a professional, respected and competent supplier of technical services, equipment and products for noise abatement and other industrial products.

New Hope Group Project Superintendent

MINETEK initially provided products for heavy mobile equipment noise abatement at the New Acland Mine. These installations have been very successful and prompted the contracting of MINETEK to conduct a full mobile fleet and fixed plant noise monitoring assessment at the Acland mine site.
