THE POWER OF THE EVALED™ EVAPORATORS

Evaporators are a proven method of reducing the volume of waste across a broad spectrum of markets. Heating waste forces water to evaporate from the bulk of the fluid, leaving the solids and drastically reducing the amount of waste content. This is an efficient method of waste disposal that lowers effluent discharge, protects the environment, achieves compliance with regulations, and saves costs.

An example of an accomplished evaporator is the Evaled™. These are ideal for use in industrial waste and process water treatment, with a maximum capacity of 250 tonnes of distillate every 24 hours. Completely computer based for continuous function without an operator, Evaled™ evaporators allow high concentration ratios and good separation levels, as well as recycling and a decrease in volumes to be disposed. These evaporators perform consuming low energy and CO2, reducing a site’s footprint when treating industrial wastewater, but what are the applications? The Evaled™ can treat wastewater that may be considered ‘challenging’ such as hazardous or toxic streams including automotive, aviation and other manufacturing industries, as well as the food and beverage sector and upstream and downstream treatment within the oil and gas industry. It has also been used to minimise wastewater for the power generation industry and water treatment within the mining industry. An example of the Evaled’s ability to adapt to multiple markets and high-performance rates was when we worked with a veterinary disinfection and detergent products manufacturing company The company has two purpose-built manufacturing facilities in the UK and exports to over 60 countries worldwide. Their production of disinfectants and detergents produced substantial volumes of wastewater which they were paying £30,000 per month to have an external supplier dispose of. They needed a way to treat the highly variable effluent whilst hitting SEPA consent limits.

We carried out thorough benchtop laboratory testing using a ‘worst case’ sample of effluent to identify that an EVALED® PC F6 evaporator was the most robust wastewater treatment solution. The system evaporates the waste water produced on site. The distillate has low enough biological and chemical oxygen demand (BOD and COD) to meet their discharge consent limits The lower volume concentrate can then be disposed of off site for a fraction of the cost without treatment.

The EVALED unit’s capacity was more than adequate to manage and treat the effluent volume of 6 m3 per day, and the installation was successfully completed in a week. The system was commissioned and validated in two days by analysing the COD and pH of the distillate to confirm compliance with the regulations. As a result, our client now has approval from Scottish Water and SEPA to discharge the majority of its wastewater to the drain.
