Textile wastewater

Textile wastewater is commonly treated with activated sludge process technology. However, its treatment performance has not been demonstrated to be very effective. In this study, the effects of micronutrient thiamine on removal efficiencies of dissolved organic carbon (DOC) and chemical oxygen deman

The discharge of textile wastewater containing dyes in the environment is worrying for both toxicological and esthetical reasons as dyes impede light penetration, damage the quality of the receiving streams and are toxic to food chain organisms. A fluidized bed reactor (FBR) with activated carbon as

Textile industry processes (dyeing, bleaching, printing and finishing) require a high-water consumption generating high amounts of wastewater. According to the literature, typically 200 and 500 L of water are needed to produce 1 kg of finished product [1]. This fact in combination with the current w

This paper focuses on the applicability of microfiltration (MF)/ultrafiltration (UF) as a pretreatment to nanofiltration (NF) for the reclamation of rinsing waters of indigo dyeing process. Two different MF alternatives, single 5 mm MF and sequential 5 mm'/0.45 mm MF, were evaluated as prefiltration

The present work experimentally studied the clarification of wastewater using the electroflotation technique (EF) with aluminum electrodes. In the first part, we have studied the principal parameters (feed tension U, distance between electrodes D, period of treatment t, pH and conductivity κ) affect

Textile industries represent an important environmental problem due to their high water consumption. In many Spanish regions with water scarcity, this fact can be an argument to make wastewater reuse necessary. In this work, a biologically treated wastewater from a cotton thread factory was subjecte

The paper comprises a case study on the implementation of the advance treatment process (ATP) in seven smallscale textile industries. The ATPs installed and commissioned are in compliance with the Statutory Board directions for recovery and reuse of treated effluent leading to zero effluent discharg

A combination of coagulation and ultrafiltration (UF) processes for textile wastewater reclamation was investigated using various types of coagulating chemicals such as polyamine, alum, polyaluminum chloride (PACl), and ferric salts. The potential of the combined system was evaluated to replace the

In the present study the application of the nanofiltration process was investigated mainly in the retention of color and chemical oxygen demand (COD) present in textile industry wastewater. Nanofiltration experiments were carried out in a pilot unit, operating in crossflow. Three different types of
