Treatment of high saline textile wastewater by activated
Textile wastewater is a combination of various chemicals and different types of dyes and has a salty nature. In this study, an SBR (sequencing batch reactor) was used to treat synthetic and real textile wastewaters in a 24 h cycle time. Remazol Brilliant Blue R, a reactive dye, was used asthe model dye. Dye concentrations ranged from 125 mg/L to 500 mg/L, and TDS (total dissolved solids
The activated sludge microorganisms could tolerate high salt concentrations and remove 60% of Brilliant Blue R dye from wastewater at a TDS concentration of 5000 mg/L; thus, SBR as a cost effective treatment system can be used for decolorization of textile wastewater even in saline conditions.

Saline wastewater treatment by electrochemical method
More recently, Dalmacija et al. (1995) considered high saline wastewater treatment by combined activated sludge process and powdered activated carbon (PAC). The results from the previous investigations have revealed that the biological method may not be a good choice, primarily because of the inhibitory effect of high salinity on the microbial
It has been observed that high salinity can strongly inhibit the aerobic biological treatment of wastewater. However, in the 1940s, the follow-up of an activated sludge effluent treatment plant functioning with seawater showed that the efficiency of aerobic treatment was similar to that of a plant operating with fresh water (Pillai and Rajagopalan, 1948).
Wastewater Treatment by Advanced Oxidation Process
The treatment of industrial wastewater (IWW) effluents is a very complex challenge due to the broad array of substances and high concentrations that it can contain. Treatment by activated sludge is more efficient and less expensive for removing high concentrations of organic compounds.
Granular activated carbon treatment of water and wastewater in large volume systems began in the U.S., England, and Germany in the early 1960's (19). Hager purposed that the development of granular activated carbon capa- ble of reactivation and reuse made adsorption an economic alternative for removal of dissolved organic contamination from
The Use of Microalgae for Coupling Wastewater Treatment
Production and emission of CO2 from different sources have caused significant changes in the climate, which is the major concern related to global warming. Among other CO2 removal approaches, microalgae can efficiently remove CO2 through the rapid production of algal biomass. In addition, microalgae have the potential to be used in wastewater treatment.
Saline water treatment has become increasingly important for drinking water supplies. The aim of this study was to evaluate the ability of the electrocoagulation (EC) process with combined aluminum electrodes in removing various types of salt from water samples collected at Sawa Lake, Al-Muthanna, Iraq. The targeted types of salt include total dissolved solids (TDS), chloride salt (Cl

Water types. If the water is already of an acceptable quality, it will not usually be necessary to subject it to any treatment. However, in the case of hard water, saline waters, water with high concentrations of nitrates, iron or manganese, for example, a specific treatment should be designed to correct the necessary parameter and ensure the water is suitable for a specific use.
- When was granular activated carbon used for water purification?
- The use of granular activated carbon (GAC) for water purification became common around the start of the 20th century (1906) when the “activation” process was applied to charcoal (which had been used for centuries).
- Can granular activated carbon filter predict trace organic removal?
- A model to predict trace organic removal in GAC filters was proposed. Drinking water treatment plants use granular activated carbon (GAC) to adsorb and remove trace organics, but the GAC has a limited lifetime in terms of adsorptive capacity and needs to be replaced before it is exhausted.
- What is granular activated carbon (GAC)?
- Granular activated carbon (GAC), based on adsorption, is the most utilised method for the removal of organic contaminants including pharmaceutical compounds; as such it is the most commonly studied.
- When is granular activated carbon (GAC) maintenance work planned?
- Maintenance work is planned from 22:00 BST on Monday 16th September 2025 to 22:00 BST on Tuesday 17th September 2025. Granular activated carbon (GAC) is used in drinking water treatment plants worldwide to remove micro-pollutants such as pesticides.
