A global exporter of diversified food and beverage products, Sabormex, is capitalising on the benefits of its high-efficiency waste water treatment plant by installing a GWE complete biogas reuse system to replace fossil fuels with green energy.

Founded in 1964 in the city of Puebla, Sabormex (“Mexican flavor”) is behind a large number of well-established Mexican brands including Clemente Jacques (sauces and dressings), La Sierra (canned foods) or Tazza, Garat and Familiar (coffee). These brands are exported to more than 20 countries bringing the authentic Mexican flavor to different corners of the world.

Such diversified production results in fast and significant changes in the composition and flows of the company’s waste water, which, before treatment, often contains high concentrations of fat, oil and grease and generally high levels of total suspended solids and COD.

In order to deal with the variable characteristics of the waste water, GWE engineered and installed a robust ANUBIX-B anaerobic reactor designed for 24 tons of COD per day. This reactor, operating since 2011, has shown consistently very high removals and stable performances.

This plant has been built by GWE’s long-standing partner ICR Ambiental from Mexico. ICR specializes in the engineering and construction of projects for water and waste water treatment, solids digestion and power generation.

ICR has partnered with GWE in many projects over the years by engineering and building waste water treatment plants in Latin America.All the suspended solids and fats sent to the waste water treatment plant are first separated in a Dissolved Air Flotation installation which generates up to 100 m3 of primary sludge every day.

In order to digest this primary sludge, which is very rich in organics, GWE has installed an ANAMIX-T reactor. This is a thermophilic continuous stirred-tank reactor which achieves high removals of pollutants even while fed with a difficult stream containing high concentrations of fat and solids. Up to 10 tons of COD per day are fed to this ANAMIX-T, with the system achieving high removal efficiencies of more than 80%.
