DNA Polyacrylamide Gel Electrophoresis – UC Davis

Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by heating. Other electrophoresis buffers such as 1x TAE can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much buffering capacity as TBE.

Challenges and Opportunities of Biocoagulant/Bioflocculant Application

For wastewater treatment, the cost of using chemical coagulants/flocculants per m 3 also varies, i.e., USD 0.10 when using alum and USD 0.15 when using ferric chloride to treat meat processing effluent , USD 19 to treat palm oil mill effluent by using alum , and up to USD 1.80 when using PAC for leachate treatment .

Polyaluminium chloride dosing effects on coagulation performance: case

Aluminium sulphate (Al 2 (SO 4) 3), commonly called alum, has long been used as a coagulant in conventional water treatment but has numerous disadvantages including the production of large volumes of post-treatment sludge, high post-treatment aluminium residue, limited coagulation pH range of 6.5 to 8.0, etc, associated with its use (Gebbie 2001; Miller et al. 2008).

Evaluation of newly developed reverse demulsifiers and cationic

In the subsequent de-oiling treatment process, reverse demulsifier (PA) was added to break the oil-in-water emulsion by replacing the natural surfactants at the oil-water interface and weakening the interface film strength, then the following flocculant (CPAM-2) coalesced them to form large flocs (Fig. 2 (e)) and promoted them to separate from the water phase and float up to the surface.
