Introduction. In recent years, the Government of Baja California has promoted not to discharge wastewater with high content of fats and oils. A company in the region dedicated to the collection of sludge, installed a horizontal centrifugation system for the extraction of oil, generating a sludge with 5% fat and oil. The result of this process is sent to a process of biodigestion and vermicompost for the generation of solid and liquid humus, which generates wastewater with high organic load that require a treatment before disposal. Objective. Develop an experimental prototype of electroflocculation to wastewater treatment with a high content of organic matter. Methodology was divided into 4 stages: 1) Physicochemical and biological characterization of the wastewater; 2) Assembly of the electroflocculation prototype; 3) Experimental assessment 4) Verification of system operation. Contribution. Through the elaboration of the prototype, the effectiveness of the electroflocculation process was confirmed for the wastewater treatment (WT) with a high content of organic matter (OM) and pathogenic bacteria, since a greater than 50% decrease of the biochemical oxygen demand (BOD5), chemical demand of oxygen (COD), fecal coliforms and Salmonella.
We present a wireless system applied to precision agriculture, made up of sensor nodes that measure soil moisture at different depths, applied to vine crops where drip irrigation is applied. The intention is to prepare a system for scaling, and to create a Wireless Sensor Network (WSN) that communicates by radio frequency with a base station (ET), so that the gathered data is stored locally and can be sent out an Internet gateway.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
