Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of
International Biodeterioration & Biodegradation
Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate polymers can be tailored by derivatization to cationic or anionic forms

What is Polyacrylamide|PAM FAQ
Polyacrylamide Knowledge 1. What is polyacrylamide PAM? Polyacrylamide is a polymer (-CH2CHCONH2-) formed from acrylamide subunits, it is long-chain polymer (same molecule repeating itself many times) designed to attract either positively
Polyacrylamide Emulsions Handbook 2-5 Principal difficulties The product contains lumps, gels, skins etc. This can plug the pumps (mostly the small ones). The first operation is to transfer the product. (See the sections above on ‘Lumps, skins,
- Can ssuf membrane replace dissolved Air Floatation in poultry processing wastewater?
- Authors to whom correspondence should be addressed. In pursuit of sustainability, we explored replacing conventional dissolved air floatation (DAF) in poultry processing wastewater (PPW) treatment with a precisely tuned 0.02 µm stainless-steel ultrafiltration (SSUF) membrane.
- What is dissolved Air Floatation (DAF) in poultry processing?
- Wastewater generated in poultry processing facilities, combined with other wastewater, is typically treated by dissolved air floatation (DAF) to remove suspended solids, such as fat, protein, feathers and flocs formed by the addition of flocculants (Dlangamandla et al., 2018 ).
- Can Dissolved Air Floatation be used to treat slaughterhouse wastewater?
- In the US, dissolved air floatation (DAF) is a widely used method for treating slaughterhouse wastewater (including PPW). Figure 1 below illustrates the current treatment process for PPW in the processing plant and the proposed treatment method to be investigated in this study for comparison. Figure 1.
- What is the wastewater treatment plant at a poultry slaughterhouse?
- The wastewater treatment plant at a poultry slaughterhouse (Céu Azul Alimentos Ltda) comprises a dissolved-air flotation (DAF) system and two upflow anaerobic sludge blanket (UASB) reactors.
