Biohydrogen and polyhydroxyalkanoate production
Biohydrogen and polyhydroxyalkanoate production from original hydrolyzed polyacrylamide-containing wastewater. Italy) and a DO meter (Sension 6, HACH, America) were used for determining pH and DO values of water sample. A TOC analyzer (Multi N/C, Analytikjena, Gemany) was used for detecting the TOC and TN values of water sample.
In present study the biodegradation of partially hydrolyzed polyacrylamide (HPAM) by bacterial strains isolated from Omani oil fields was analyzed. HPAMs are extensively used in oil fields for enhanced oil recovery operations.
The Effect of Hyrolysis of Polyacrylamide on Solution
Abstract Many excellent articles have reported various aspects of the nature of hydrolyzed polyacrylamide flow in porous media. The polyacrylamide flow in porous media. The degree of mobility reduction is proportional to: 1. the viscosity of the pol
Branched-preformed particle gel (B-PPG) is a novel agent for EOR application in mature reservoirs. To improve the enhanced oil recovery (EOR) performance of B-PPG, the heterogeneous combination flooding system composed of B-PPG, hydrolyzed polyacrylamide (HPAM), and surfactant was proposed.
Global Polyacrylamide Market to 2025 - Major Players are
DUBLIN, November 6, 2017 /PRNewswire/ --. The "Polyacrylamide Market Analysis By Product, And Segment Forecasts, 2014 - 2025" report has been added to Research and Markets' offering.. The global
Partially hydrolyzed polyacrylamide (HPAM) as the main component of slickwater fracturing fluid is a shear-sensitive polymer, which suffers from mechanical degradation at turbulent flow rates. Five different concentrations of HPAM as well as mixtures of polyacrylamide/xanthan gum were prepared to investigate the possibility of improving shear stability of HPAM.

Polymer flooding is the most successful chemical method to enhance oil recovery. This technique has achieved large-scale field application in China. Polymer flooding is also being tested in several heavy oil fields. For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery.

- How much does wastewater treatment cost?
- The weighted average, depending on the treated volume of wastewater, is 0.3609 €/m 3. Table 5. Environmental benefit of wastewater treatment in €/m 3. Fig. 2 shows the environmental benefits derived from the elimination of pollutants.
- Does wastewater treatment have a market value?
- Moreover, the wastewater treatment process has significant associated environmental benefits. However, these benefits are often left uncalculated because they have no market value. In this paper, using the concept of shadow price, a quantification of the environmental benefits derived from wastewater treatment is made.
- How is the environmental benefit of wastewater treatment calculated?
- By considering the volume of pollutants removed in the treatment process (kg/year), the volume of treated wastewater (m 3 /year), and the shadow prices obtained for each pollutant (see Table 4), the overall environmental benefit resulting from wastewater treatment is calculated as shown in Table 5.
- Is cost efficiency important in wastewater treatment and water reuse projects?
- Despite the importance of cost efficiency in the context of wastewater treatment and water reuse projects, few studies are present in the literature. The difficulty of obtaining information and the shortage of researchers working in the economic analysis of treatment processes are possible factors.
