INVENT Press Release

Thanks to the mixing and aeration technology from Erlangen, Germany, a state-of-the-art wastewater treatment plant is now able to transform wastewater from a vacation resort into valuable hydration for an evergreen golf paradise.

There is plenty to discover in San Miguel de Allende, Mexico. Its fortified baroque downtown with featuring a number of striking church buildings has been a UNESCO World Heritage Site since 2008.

In the recent past, sophisticated weekend and vacation home developments have emerged around this gem. In keeping with the upscale construction quality, the builders of one of these resorts implemented an equally high-quality wastewater treatment plant fitted with technical equipment from INVENT.

The plant, which was built in 2017, is designed for a wastewater volume of 1,080 cubic meters per day and operates based on SBR treatment technology. A “Sequencing Batch Reactor” requires the construction of basins for pre-treatment, for the periodically repeated multi-phase sewage sludge treatment (filling, aeration, mixing, emptying) and for the clear water that in the end is the result of the process.

This is where the INVENT technology comes in with three rectangular tanks. In the SBR tank (dimensions length 22 m x width 10 m x depth 5 m), two HYPERCLASSIC®-Mixing and Aeration Systems, each with a diameter of 2.5 m, along with an aeration system, ensure uniform mixing of the content. In a final step, the extracted water is discharged from the SBR basin via an iDEC®-Decanting System with a pipe diameter of 20 cm.

INVENT HYPERCLASSIC®-Mixer featuring a diameter of 2 m is utilized in the 12 m x 5 m x 5 m equalization basin, and an iCBA®-Aeration System with 18 aerators is utilized in the sewage sludge basin of the same size, to prevent, among other things, foul odor emissions.

With the water extracted from the wastewater treatment plant, the operators of a neighboring golf course cover their needs for the green areas and the artificial lake in between.

Now in its fifth year, the INVENT technology is running efficiently and contributing almost silently, yet effectively, to the comfort and recreational value of the residential and recreational complex.
