Bengal Fine Powder Type Temperature-Resistant Salt-Resistant Polyacrylamide for Tannery Wastewater Treatment

Mar 12, 2004 · The temperature at the time of feeding is within the range of from (surface treatment temperature) to [(surface treatment temperature)−30° C.] and varies depending upon the circumferential temperature, the connecting distance, and the like. In the cooling machine, the water-absorbing resin has a temperature gradient.

Sources of wastewater include spent electrolytic baths, slimes recovery, spent acid from hydrometallurgy processes, cooling water, air scrubbers, washdowns, stormwater, and sludges from wastewater treatment processes that require reuse/recovery or appropriate disposal. The main portion of the solid waste is discarded slag from the smelter.

Aug 28, 2020 · The samples and KBr were ground to a fine powder that was pressed into a pellet, which was then analyzed. 1 H NMR measurements of samples in D 2 O were carried out using a Bruker AVANCE DRX-500 spectrometer in proton noise-decoupling mode with a standard 5 mm probe at ambient temperature (25 °C).

It can be used as a drag reduction agent for fracturing, because to reach the field application conditions, the use of more quick-dissoluble non-ionic polyacrylamide emulsion and non-ionic polyacrylamide fine powder products, to decrease the rough fluid turbulence in the pipeline, reduce the effect of molecular movement resistance.

Wastewater treatment and recycling of agricultural and industrial wastes are other important uses of microbial technology. It is expected that microbes in combination with developments in electronics, software, digital imaging, and nanotechnology will play a significant role in solving global problems of the twenty-first century, including ...

Currently, such wastewater is treated mainly by a chemical flocculant-polyacrylamide combined with air flotation and anaerobic fermentation. The polyacrylamide dosage used is approximately 10 ppm to 15 ppm, the cost of the treatment is approximately 0.2 ¥/t, and the treatment works well at Anhui Ruifuxiang Enterprise.
