The growth in the production of dairy products entails the problem of treating wastewater from the operation of dairy plants. This article discusses the possibility of using a purification technological scheme using sorbents from natural waste, which is an alternative to the traditional one, which includes a biological stage. In this study, activated biochar from rice husks and graphite are used as sorbents. As a result of purification according to the proposed scheme, the quality of the treated water corresponds to the normative indicators when discharged into the city sewage network.

“…Presently, pump water is treated with coagulants and flocculants to reduce the concentration of organic matter to comply with the environmental regulations [Loza Pacheco, 2014]. This treatment reports a removal efficiency of 85.8% and 99.2% for TSS and fats, respectively [Cristóvão et al, 2014]; however, this treatment process increases the concentration of inorganic salts in Optimizing the Reduction of Total Suspended Solids in Pump Water from Fish Factories Through Electrocoagulation using Response Surface Methodology Edwar Aguilar-Ascón 1 , Walter Neyra-Ascón 1 , Miguel Albrecht-Ruiz 2 , Alonso Ibarra-Basurto 3 the treated water and favors the buildup of salts in solids [Espinoza Villegas, 2016], thereby restricting the possibility of using it as animal feed or fertilizer.…”

“…It is from the anode or sacrificial electrode (usually made of aluminum or iron), where metallic cations are generated and hydrolyzed in situ to form coagulants [Rodríguez et al, 2010], which agglomerate colloidal particles. This process separates pollutants through flotation and precipitation due to the small hydrogen bubbles generated by the cathode [Akansha et al, 2020].…”

This study aims to optimize the removal of total suspended solids (TSS) in pump water from fish flour factories through electrocoagulation technology and to determine the effects of the main operation parameters. Pump water has high conductivity (40.1 mS), due to the presence of dissolved salts and contains high concentration of organic substances (12,360 mg/L of TSS and 520 mg/L of fats). In this study, pump water was treated in an electrocoagulation reactor with aluminum electrodes using Response Surface Methodology with a 3 k factorial design based on two factors, current intensity (I) of 8-13 A and treatment time (t) of 20-40 minutes. The percentage of TSS removed from the water was used as the response variable. The results revealed that I and t significantly (p < 0.05) influenced the process. In accordance, the optimal operational parameters for TSS removal were I = 13 A and t = 30 minutes. Using these conditions, TSS removal efficiency of 99.9% was achieved. The sewage sludge generated with these optimal process conditions indicated 19.3% of ash content, 6.2% of salt, 1.7% of aluminum, 0.3% of iron, 0.4% of potassium, 256 ppm of zinc, and 2.1% of phosphorus. Hence, the results of this study affirm that electrocoagulation can be considered as a solution for marine pollution caused by fishing industries.
