A company’s mixing and aeration technology has helped a state-of-the-art wastewater treatment plant transform wastewater from a vacation resort into valuable hydration for a golf resort.
San Miguel de Allende, Mexico has been a UNESCO World Heritage Site since 2008 for its fortified baroque downtown featuring a number of striking church buildings.
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 Environmental Technologies, a water and wastewater treatment company.
The plant, which was built in 2017, is designed for a wastewater volume of 1,080 cubic meters per day and operates based on sequencing batch reactor (SBR) treatment technology. An SBR requires the construction of basins for pre-treatment, to periodically repeat multi-phase sewage sludge treatment (filling, aeration, mixing, emptying). This is where INVENT’s 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®-Mixers, 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.
A HYPERCLASSIC®-Mixer featuring a diameter of 2 m is utilized in the 12 x 5 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 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 plant is running efficiently and contributing almost silently to the comfort and recreational value of the residential and recreational complex.
