• 2022-06-28 Simple method to distinguish the quality difference of polyacrylamide

  A simple method to distinguish the quality of polyacrylamide: at present, it is impossible to distinguish by observing powder solids. To make a complete difference, a dissolution comparison experiment must be done: take the same quality of solids to make liquids of equal concentration (such as one thousandth), and mix well as much as possible. With the passage of time (about half an hour), the solid is almost completely dissolved, the concentration and viscosity of the high m…

• 2022-05-20 How to expand the cultivation of denitrifying bacteria？

  Denitrifying bacteria are mostly heterooxic and facultative anaerobic bacteria. They use the oxygen in nitric acid to oxidize organic matter under the condition of no molecular oxygen to obtain the ability required for their own life activities, and finally convert nitrate nitrogen into nitrogen gas. . There are more than 50 genera of denitrifying bacteria, including Pseudomonas, Alcaligenes, Neisseria, Nitrobacteria, Rhodospirillaceae, Fibermycetaceae, Spirobacterium, Rhizob…
