Roles of functional microbial flocculant in dyeing
1. Introduction. Dyeing wastewater deriving from the textile dyeing industry possesses the serious threat to public and ecosystem due to nonbiodegradable synthetic dyes, heavy metals and other chemicals in wastewater (Vakili et al., 2014; Al-Qodah et al., 2007).Azo dyes, as one kind of the most harmful dyes, account for more than half of the total usage of dyes in the printing and dyeing
In addition, Li Mengying and others studied the adsorption treatment of printing and dyeing wastewater by Penicillium, and found that it has a good treatment effect on the color of black and red dyeing bath wastewater, and the removal rate reached 98.0% and 74.5%. The development offers new options.
Treatment of a simulated textile wastewater in a
In order to evaluate the effect of the NaCl and the auxiliary dyeing chemicals, two simulated wastewaters were prepared: (i) simulated wastewater containing salt and auxiliary chemicals (as described in Section 2.1), and (ii) simulated wastewater prepared without NaCl addition. Adsorption isotherms for these simulated wastewaters were
An experimental study on the treatment of dyeing and printing wastewater by adsorption process was carried out.The results show that the carbon black or coal ash has a good adsorption ability on treatment of dyeing and printing wastew-ater. They both can take the place of activated carbon.The main factors affecting the adsorption performance were studied.

The reactive azo dye Remazol Brilliant Violet-5R (RBV-5R, chemical formula: C 20 H 16 N 3 Na 3 O 15 S 4, MW = 734.58 g/mol) was obtained from DyStar Singapore Pte. Ltd., Singapore and was used
Treatment of Four Dyes Wastewater Using Fenton Reagent
At the TIB Technik/Naturwissenschaften (Science/Technology) and TIB Conti-Campus sites, lending and returning items (Monday to Friday from 9:00 to 15:00) and registration (Monday
Fenton reaction remains an efficient technique for decomposing recalcitrant organic contaminants. Nevertheless, traditional Fenton response has many lim-itations like the necessity of acidic pH circumstance, the formation of iron sludge and the need for elevated chemical introductions. Procedures like het-erogeneous Fenton, fluidized-bed Fenton, employment of chelating products and in situ
Risk Assessment of Wastewater Disinfection
Treatment capacity of the wastewater treatment plant 2. Number of workers in SIC and plant or number in SIC state-wide 3. Number of employee-hours in SIC at plant or number in SIC statewide Although SDS reports are open to the public, some states code information to prevent tracking accidents to the employer or individual treatment plant.
In this work, nanochitosan (NC) was prepared through ionic gelation using low molecular weight chitosan and maleic acid (MA). The synthesized NC was characterized by atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). During preparation, the particle size of the material depended on parameters such as concentration of chitosan
