Researchers at the Universidad Autónoma Metropolitana (UAM ) and the Graduate School of Ecatepec work a prototype to treat wastewater business car wash to be refurbished.
This study house reported that the use of this technology liquid separation achieved between 95 and 99% of oils and fats , which is reusaría for the same purpose. In a statement, adding that the invention UAM help minimize water usage and prevent highly contaminated liquid hydrocarbons reach the drain.
The efficiency of this new technology is superior to conventional separators that have oil and grease as well as methods such as electrocoagulation, so the reuse system is viable in economic terms, he said.
Researcher Judith Martinez Cardoso, Division of Basic Sciences and Engineering Iztapalapa Unit and project coordinator, said the treatment has already been patented by the UAM and this year the prototype scale with financial support from the Institute of Science and Federal District Technology (ICyTDF).
He explained that this technology is based on clariflocuación process, which consists of adding a flocculant solution to contaminated water and within 12 to 25 minutes released almost all the liquid of suspended solids that are formed during the process .
Due to its biodegradable and biocompatible characteristics, the flocculant proposed by specialists to treat the water does not harm to anyone who handles, which surpasses its safety to other conventional treatment based on aluminum salts accumulation in the body generates the disease Alzheimer’s disease.
The potential impact of this technology transfer on water usage is significant, considering that in the valley of Mexico, there are nearly four million cars and the complete cleaning service of a vehicle spends on average 177 liters , and the trucks and trailers, 880 thousand 100 liters, respectively.
