New “species” in water treatments

“Man gave names to all the animals, in the beginning” (Bob Dylan). In the late 1970s, one of the most important musicians in history released Slow Train Coming which included the song Man Gave Names to All the Animals. What would you think if one of them, an ALBATROS, were responsible for purifying your wastewater? And what if a PELÍCANO gave you distilled water for your process with a conductivity of up to 5 µS/cm? And can you imagine a NARVAL working at your leachate treatment plant?

Well, this is what Incro, S.A. has been doing for the last three years in the waste treatment sector. Their evaporation equipment, which purifies numerous types of wastewater (cooling and lubricant emulsions, active baths, rinses, saline water, etc.) have been given animal names based on their size: CAIMÁN, PINGÜINO, FLAMENCO . Spanish names from a Spanish company with Spanish capital, but with extensive international presence. It belongs equally to the ACS Group, recognized worldwide as a leader in the construction, services and concessions sector, and the Villar Mir Group, one of the biggest conglomerates in Spain which produces the largest amount of silicon metal in the world. Incro, S.A. is an engineering company with more than 40 years of experience and specializes in technology licensing and the production of wastewater treatment plants. Its achievements can be found on all five continents.

Since its foundation in 1975, the company’s commitment to innovation and the environment has been a priority. Patents and recognized improvements emerge constantly from its highly qualified technicians. Incro, S.A. won the prestigious Cambio Financiero Awards as Most Innovative Company in Spain in 2013.

In the last twenty years, Incro, S.A. has specialized in the treatment of high-load wastewater through evaporation. With its proprietary technology it has resolved discharge issues in sectors as diverse as the automotive industry, municipal waste landfills, the pharmaceutical industry, the bulk and fine chemicals industry, the agri-food sector, fish farms, livestock holdings, etc. In 2009 the company added Mechanical Vapor Compression technology (MVC) to its portfolio of products. Since 2013 it has been designing and manufacturing its own evaporators, as well as undertaking the installation, start-up, maintenance and supervision of their operation.

As you can see on the company’s website, its ‘animals’ achieve optimal use of water and energy resources. Its equipment distils the effluent, recovering high quality water (with a conductivity of down to 5 µS/cm).  All the pollutants are confined to a concentrate that represents on average 1%-5% of the incoming wastewater. There is no evaporator on the market that achieves such a high quality of distilled water with such a small amount of concentrate and such low energy consumption.

A simulation on the website explains the elegance of the MVC technology which manages to evaporate the effluent thanks to the energy it recovers from condensing the generated steam. The only energy needed is electricity, which is supplied to a compressor that heats the vapor while at the same time increasing the pressure from a slight vacuum to atmospheric pressure. Hence the name: Mechanical Vapor Compression. This technology is ousting the old physical/chemical equipment thanks to the benefits it offers of zero liquid discharge, high quality distilled water, the absence of chemical reagents, minimal footprint, and reduction of personnel costs, not to mention the savings from evaporation by vacuum pump and very low operating costs.

Behind our friendly DELFIN and ORCA there is a team of highly qualified technicians, with a high percentage of industrial engineers specializing in chemistry, who analyse the facility and discharge requirements of each individual client to design the most suitable plant for their needs. In doing so, they undertake the relevant laboratory tests or pilot plants. Professional advice becomes into lower investment and operating costs for clients.
