The disposal of spent coolants has become a significant factor in the operational cost of a plant, hitting small to medium enterprises particularly hard as they frequently lack the space, capital, and the technical personnel to utilise the recycling or treatment capabilities available to larger companies. Yet, their costs and liabilities are proportionately the same or greater.

Dimac Tooling  have now come up with an entirely different approach to the problem, and as such, a solution. Used coolants are normally 97% water, so if the water is removed, the amount requiring disposal should be reduced to a mere 3% of the original volume.

To achieve this goal of reducing spent coolant for disposal, Dimac Tooling recommends using a piece of equipment known as the ‘Water Eater’, made by EMC in the USA. The 'Water Eater' waste water evaporator is available in gas and electric heated models and evaporation rates range from 15L to 208L per hour. An optional auto fill system automates the process and also allows for 24 hour operation.

The Waste Eater  waste water evaporator heats the spent collants through the floor of the unit, while at the same time a power exhaust system continuously draws air across the surface of the heated liquid to speed evaporation and carry the water vapour out of the unit's stack. Should the unit run dry, an automatic shutoff prevents damage.

A unique feature of the Water Eater is that it allows almost complete elimination of the spent coolant. The Water Eater waste water evaporator has been engineered to efficiently evaporate the water content from most non-volatile water-based liquids.

A power exhaust system releases the moisture safely into the air, leaving only a small spent coolant residue requiring disposal. The dry residue is simply scraped from the obstruction-free bottom of the unit periodically. Alternatively, the highly concentrated spent coolant residue, which remains after many reductions, may be taken out before becoming totally dry.

A fully removable cover that allows complete access to the entire tank is also provided to minimise cleanout time of the Waste Eater waste water evaporator. Most Water Eater waste water evaporators also have a low top frame height, which allows easy accessibility without the need for footstools or stands.

The harsh environment inside a waste water evaporator requires that only heavy gauge materials be used, which is why all tanks, both carbon and 316L stainless steel, are of mig welded, 12 gauge steel construction. 316L stainless steel units also have covers, lid, and vent stack of stainless steel.

To keep the energy costs for evaporation as low as possible, the Water Eater waste water evaporator features a large heat transfer area of the burner tube or heat exchanger. This minimises heat-up time and decreases energy costs. This large surface area also has an advantage in that fewer hot spots are created and any sludge or scale buildup which can insulate and reduce system efficiency is minimised.

The massive reduction in the volume of spent coolants requiring disposal not only slashes disposal costs, but also economises by reducing storage area requirements, labour and time for and frequency of handling.

All Water Eater waste water evaporators have been designed to operate simply and efficiently, and are constructed of quality materials and equipment to assure trouble-free operation and long-life service.
