“…Treatment of industrial wastewater is an excellent challenge in CETPs due to the complex nature of wastewater from different industries. However, research related to MSMEs and CETPs is not much explored [13]. Moreover, literature related to comparative studies on the treatment of industrial effluents is not widely reported in scientific documents to provide a proper understanding of the treatment efficacy of advanced wastewater technologies.…”

“…The concept of CETPs in India was adopted to achieve end-of-pipe treatment of combined wastewater to benefit from the scale of operation. In addition, the CETPs also reduce the number of discharge points in an industrial estate for better enforcement by environmental regulatory agencies [13,14].…”

“…Typically, conventional biological treatment fails to treat industrial effluents because the effluents from several industries are mixed, and as a result, it possesses complex characteristics. Biological processes are widely adopted for most organic wastewaters yet do not always give satisfactory results [8,13,14]. Especially for the treatment of industrial wastewaters, many organic substances produced by the chemical and related industries are inhibitory, toxic, or resistant to biological treatment.…”

The investigation was inspired by the declaration of critically polluted industrial zones in India. It was also reported that most of the Common Effluent Treatment Plants (CETPs) are non-compliant due to higher COD values in discharge than regulatory norms. Furthermore, most of the literature has not reported the efficacy of advanced wastewater technologies for real industrial effluent. Thus, this research focused on field trials of scalable advanced wastewater technologies in Vatva Industrial Estate (VIE), Ahmedabad. The potential of physico-chemical and advanced treatment processes are explored for applicability in industrial wastewater treatment. Thus, for this research, three industries from each sector, i.e., textile processing, dyes, and dye intermediates, a total of nine different industries were chosen. A sufficient volume of effluent was collected from each industry for detailed investigations. The initial COD loading observed was in the range of 68 to 7074, 30 to 896, and 100 to 1541 kg COD/day for textile processing, dyes, and dye intermediates, respectively, with significant variation in the qualitative profiles. The collected effluent was treated by electrocoagulation and Fenton's reagent in batch scale reactors. The batch scale reactors for both the technologies were of 1L size. The results of treatability studies represented that Fenton's reagent performed better than the electrocoagulation process for most of the industries selected in this study. This research provides insight for improvement in the environmental performance of the individual industries in general and CETPs in particular.

“…MB has some harmful effects on the body, including burning of the eyes, which can cause permanent damage, increased heart rate, nausea, vomiting, and shock [21][22][23]. At present, the treatment technology for dye wastewater includes physical (adsorption and membrane filtration), chemical (coagulation/flocculation and chemical oxidation), and biological methods [24,25]. Among them, adsorption is considered to be one of the simplest, most effective, and least costly technologies [26].…”

Synthesis of Porous Material from Coal Gasification Fine Slag Residual Carbon and Its Application in Removal of Methylene Blue

et al. 2021

A large amount of coal gasification slag is produced every year in China. However, most of the current disposal is into landfills, which causes serious harm to the environment. In this research, coal gasification fine slag residual carbon porous material (GFSA) was prepared using gasification fine slag foam flotation obtained carbon residue (GFSF) as raw material and an adsorbent to carry out an adsorption test on waste liquid containing methylene blue (MB). The effects of activation parameters (GFSF/KOH ratio mass ratio, activation temperature, and activation time) on the cation exchange capacity (CEC) of GFSA were investigated. The total specific surface area and pore volume of GSFA with the highest CEC were 574.02 m2/g and 0.467 cm3/g, respectively. The degree of pore formation had an important effect on CEC. The maximum adsorption capacity of GFSA on MB was 19.18 mg/g in the MB adsorption test. The effects of pH, adsorption time, amount of adsorbent, and initial MB concentration on adsorption efficiency were studied. Langmuir isotherm and quasi second-order kinetic model have a good fitting effect on the adsorption isotherm and kinetic model of MB.

“…El tratamiento físico de las aguas residuales se refiere a la eliminación de los contaminantes sin cambiar sus propiedades bioquímicas, ya que dichos mecanismos de tratamiento ignoran la influencia de cualquier agente químico o biológico. Los tratamientos físicos implican la eliminación de contaminantes de las aguas residuales por simples fuerzas físicas y suelen preceder a los tratamientos biológicos o químicos (Ghumra et al, 2021). Algunas de las estrategias de tratamiento físico comúnmente adoptadas incluyen cribado, sedimentación, desnatado, aireación, tratamiento térmico, adsorción, tecnología basada en membranas, etc., siendo la transferencia de masa el planteamiento en el que se basa la técnica física (Samsami et al, 2020).…”
