Acrylamide in Drinking-water
Acrylamide was detected at levels of <5 µg/litre in both river water and tap water in an area where polyacrylamides were used in the treatment of potable water. Samples from public drinking-water supply wells in West Virginia, USA, contained
Polyacrylamide gels are characterized by two parameters: total monomer concentration (%T, in g/100 ml) and weight percentage of crosslinker (%C). By varying these two parameters, the pore size of the gel can be optimized to yield the best
Running agarose and polyacrylamide gels
The basics. Agarose gels can be used to resolve large fragments of DNA. Polyacrylamide gels are used to separate shorter nucleic acids, generally in the range of 1−1000 base pairs, based on the concentration used (Figure 1). These gels can be

- Flotation technology is widely used for the treatment of conventional oilfield produced water. This process uses fine gas bubbles to separate suspended particles that are not easily separated by sedimentation. When gas is injected into produced water, suspended particulates and oil droplets are attached to the air bubbles as it rises.
- How can saltworks improve your hydrocarbon recovery?
- Saltworks’ advanced solutions can reduce polymer consumption and deliver recycled injection water with lower hardness and suspended solids which can improve well performance. Let us help improve you improve hydrocarbon recovery and lower operating costs.
- What is produced water treatment technology?
- Comparison of produced water treatment technologies I. This is a well-established technology that has been used for produced water treatment . It is mostly effective for feed water with chloride levels below 6600 mg/l This technology has been extensively used for produced water treatment.
- Which technology is used to treat produced water?
- Although this technology is mainly associated with sea water desalination, various enhanced vapour compression technologies have been employed for produced water treatment . Hybrid MED–VCD has been recently used to treat produced water. Increased production and enhanced energy efficiency are the major advantages of this system.
