Analysis of physical and chemical properties of wastewater treatment by an experimental laboratory facility for water reuse

Abstract

This paper studies the efficiency of water treatment by detecting the main physical and chemical properties of water at the experimental facility for recycling wastewater in a poultry farm. Analysis of physical and chemical properties of wastewater at different lines of slaughtering stage revealed that the laboratory facility combined with different water treatment technologies efficiently purifies water to be reused. This facility by the process of electrocoagulation and ultraviolet disinfection ensures high degree of purification. Electrolysis was carried out at the direct current of 0.6-1.5 A with a voltage of up to 6 V for 10 and 5 minutes. Aluminum and titanium plates were used as electrodes. The results revealed that the content of nitrogen compounds was 0.119-36.2 mg/dm3 before purification and 0.019-5.3 mg/dm3 after purification, phosphorus variables were from 5.79 mg/dm3 to 0.11 mg/dm3, and chlorine, respectively, equaled from 0.45 mg/dm3 to 0.01 mg/dm3.
