Advanced treatment of bio-treated dyeing and finishing
Bio-treated dyeing and finishing wastewater (BDFW) in textile industry was collected from the effluent of a real textile wastewater treatment plant that is located in Zhejiang province, China, and operated in an oxidation ditch with a scale of 600,000 m 3 per day.
2.2. Physicochemical treatment of wastewater. The effect of physicochemical treatment of wastewater, prior to its feed to the trickling filter, was studied using addition of Ca(OH) 2 at a range of 2.5–10 mg/L (measured as final concentration) and 4.5 mL of FeSO 4 ·7H 2 O 0.8% (w/w) solution per liter of wastewater. 2.3. Pilot scale trickling

Advanced treatment of bio-treated Chinese patent medicine
Advanced treatment of bio-treated Chinese patent medicine wastewater using ozone/peroxymonosulfate-upflow biological aerated filter promoted catalytic wet oxidation of fulvic acid as a model organic compound in landfill pollutants in advanced treatment processes of biological treatment effluent of dyeing wastewater. Environ. Chem., 33
A sequential anaerobic-aerobic batch reactor was used to treat 3,6-dichloro-2-methoxybenzoic acid (dicamba) during a long operation period of 340 days in the presence of disodium anthraquinone-2,6-disulphonate (AQS) as redox mediator. The sludge activity was evaluated for different dosages of dicamba over constant hydraulic retention time (HRT), neutral pH (6.5–7.5) and at ambient reactor

CONCLUSIONS Overall, the following conclusions were reached: (1) in most cases biological treatment of dyeing wastewaters, while inadequate for color removal, can achieve high (>90%) levels of soluble BOD removal (2) in one case, the dyeing wastewater was in- hibitory to removal of BOD, even at low strengths, possibly indicating the need for
COLOR AND COD REMOVAL OF DYEING Title WASTEWATER
Wastewater sample used in coagulation experiments was dyeing wastewater containing green vat dye from Minh Khai Textile Company with an initial COD content of 1066 mg/l, collected directly from a dyeing machine after dyeing. Wastewater for Fenton treatment studies was wastewater pre-treated by coagulation. Coagulants (Ah(S04)3, FeS04) and pH

- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- What is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
- What is ionic polyacrylamide?
- The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminum chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.
