Sustainable Energy Recovery in Wastewater Treatment
Microbial fuel cells (MFCs) recover energy sustainably in wastewater treatment. Performance of non-noble cathode catalysts with low cost in neutral medium is vital for stable power generation. Nitrogen-doped graphene (NG) as cathode catalyst was observed to exhibit high and durable activity at buffered pH 7.0 during electrochemical measurements and in MFCs with respect to Pt/C counterpart
The paper intreduces the treatment of high fluorine drinking water with natural zeolites pretreated by alkaline liquid. The fluorine content of 3- 10 mg/L in drinking water can decrease to 0. 5-0. 8 mg/L and all indexes of the water comes up to the national standard of
A new method for treating fluorine wastewater to reduce
Abstract: Reduction of the sludge generated in fluorine wastewater treatment is a critical problem for the semiconductor industry. We have developed a new method for treating fluorine wastewater in order to reduce sludge and running costs. This method utilizes a small amount of Al(OH)/sub 3/ not only as an aggregator for CaF/sub 2/ generated from fluoride ions in the wastewater but also as an

Reduction of Fluorine-containing Industrial Waste Using
Reduction of Fluorine-containing Industrial Waste Using Aluminum-solubility Method Hisao KUROSAKI* Abstract About 30% of industrial waste from semiconductor plants is fluorine-containing waste. To decrease this we examined a new waste treatment method. This paper describes the theory, features and performance of this method.
Fluoride Removal from Wastewater. Fluorine (F) is a naturally occurring element found our air, soil, and water. Fluorine is among the most reactive elements on the periodic table and is rarely, if ever, found as elemental fluorine in our environment and is more known and observed as a fluoride in many different naturally occurring compounds.
Simultaneous antibiotic degradation, nitrogen removal
A novel microalgae-bacteria powered biofuel cell (MBBFC) is designed for aquaculture wastewater treatment and energy recovery, in which algal-bacterial cooperation coupling with cathodic bioelectrochemiccal process for efficient nitrogen removal while simultaneously driving anodic bioelectrochemical degradation of antibiotic florfenicol (FLO) with instantaneous electrons uptake from co
Polyacrylamide (PAM)is a kind of water soluble polymer, has unique effect to increase the viscosity of water or to promote the flocculation of particles present in water, it can also reduce the frictional resistance between the liquid. According to the different ion characteristics, PAM has three types: Anionic PAM, Cationic PAM and Nonionic PAM.

Nonionic polyacrylamide is a kind of soluble high molecular weight polymer or polyelectrolyte. It is the white powder or granule with the solid content ≥90% and molecular weight of 2-22 million. It is non-toxic, and can be dissolved in the water
- Is polyacrylamide contaminated with acrylamide?
- Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food.
- What is the standard state of polyacrylamide?
- Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?
- ) Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -).
- 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.
- Is polyacrylamide a polyolefin?
- Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone.
