Keiken and wastewater treatment: ham industry

Industrial effluents generate great environmental impacts if they are not treated properly. In order to limit this impact, there is a strict legislation that penalizes illegal dumping and which obliges its treatment and purification to parameters that avoid or diminish the negative effects on the natural environment, aquifers or seas. Industrial wastewater have a higher risk factor than urban ones, due to the chemicals used in manufacturing processes and the diversity of their compositions.

In the case of the ham industry, it is not going to be an exception, highlighting the wastewater from the washing of the ham after the salty stage. This brine can generate unwanted environmental impacts and its direct discharge to the municipal collector is forbidden.

At KEIKEN Engineering we can provide a solution, since we are experts in desalination and wastewater treatment. The characteristics of these wastewater make them ideal for our compact plants: Reverse osmosis plants, MED and MSF plants, direct osmosis and membrane distillation, among others, combined with concentrators and degreasing treatments.

In addition, as a feature to highlight, these plants could be adapted to obtain a usable raw material in other environments: the salt contained in the water washing and desalination of the ham: suitable for use on roads.

Equipment designed and proposed by KEIKEN are clearly the best solution:

• Being compact automatic plants
• Very competitive
• Getting the best results
• They are modular and can go containerized or not, depending on the needs of each project.

One of KEIKEN's R &D projects consists of a "Sustainable Desalination plant for Efficient Water and Energy management cycle", which has obtained the official certification of the IBEROEKA Project. Achieving a performance and electric consumptions lower than 1kWh per cubic meter of distilled water. Much more efficient compared to the high energy consumption of reverse osmosis, the best consumptions hover 4-5kWh per cubic meter in large desalination.

It is a process in which the driving force is the vapor pressure gradient generated on both sides of a membrane between cold water and hot water, as seen in the picture.

The membrane allows the separation of volatile matter from non-volatile matter and therefore is a process that rejects 100% of solids and non-volatile matter.

In KEIKEN we can hybridize our compact plants with renewable energies, which provides a reduction in operating costs and reduction of the carbon footprint (CO2 emissions). To learn more about membrane distillation projects with renewable energies proposed by KEIKEN, follow the link link.
