Analysis of Wastewater Treatment Efficiency in a Soft Drinks Industry

Abstract

Abstract. During manufacturing processes, most industrial plants generate wastewater which could become harmful to the environment. Discharge of untreated or improperly treated industrial wastewaters into surface water could, in fact, lead to deterioration of the receiving water body's quality. This paper concerns wastewater treatment solutions used in the soft drink production industry: wastewater treatment plant effectiveness analysis was determined in terms of basic pollution indicators, such as BOD, COD, TSS and variable pH. Initially, the performance of mechanic-biological systems for the treatment of wastewater from a specific beverages production process was studied in different periods, due to wastewater flow fluctuation. The study then showed the positive effects on treatment of wastewater augmentation by methanol, nitrogen and phosphorus salts dosed into it during the treatment process. Results confirm that after implemented modification (methanol, nitrogen and phosphorus additions) pollution removal occurs mostly with higher efficiency.

Influence of Cotton Bleaching Methods on the Parameters of Generated Textile Industrial Wastewater

“…Industrial wastewater is characterized by highly variable combinations of pollutants, the precise detection and determination of which is becoming increasingly important [2]. The discharge of untreated or improperly treated industrial wastewater into surface water may cause deterioration in the quality of the receiving water body [3]. The primary purpose of wastewater treatment is to protect surface water quality and aquatic life, promote beneficial and recreational uses of waterways, and comply with local water emission standards [4].…”

“…En este caso, las aguas residuales llegan a una planta de tratamiento que cuenta con un tren conformado por operaciones de homogenización, ecualización, biofiltración, lodos activados y clarificación, donde los procesos aerobios y anaerobios son un componente integral para la degradación biológica. Sin embargo, las reacciones en los procesos de homogenización y ecualización generan lodos en el tratamiento primario que afectan las tasas de remoción y las operaciones del tratamiento secundario, así como costos adicionales de manejo al ser un residuo peligroso [4].…”

“…The beverage industry Wastewater may include wastes of wasted syrup and drink, bottle wash water, detergents and caustic products. These pollutants contain organic and inorganic substances described by the biochemical oxygen demand (BOD5) and the chemical oxygen demand (COD) (Boguniewicz-Zabłocka et al, 2017).…”
