China High Quality Polyamine High Viscosity for Water Treatment, Find details about China Polyamine, Flocculant from High Quality Polyamine High Viscosity for Water Treatment - Yixing Bluwat

Jun 01, 2018 · Raw Liquid Waste Treatment System and Process. NASA Technical Reports Server (NTRS) Humphrey, M. F. (Inventor)-01. A raw sewage treatment process is disclosed in which substantially all the non-dissolved matter, suspended in the sewage water is first separated from the water, in which at least organic matter remains dissolved. The non-dissolved material …

processing plant. Therefore, due to the high-strength characteristics of the slaughterhouse efflu-ents, an extensive treatment for a safe discharge into the environment is required. Thus, the com-bination of biological processes and advanced oxidation technologies for slaughterhouse waste-water treatment is evaluated in this study.

The crude oil and water (either deionized water or brine) were heated separately at 60 °C for 30 min; subsequently, the oil was added dropwise into the water under rigorous shearing by an emulsifier (Waring LB20EG, USA) at 4000 r/min for 15 min to obtain a model oily water with an oil content of approximately 1000 mg/L.

Biosolids samples from 3 sewage treatment plants (STPs) were tested for VSR (%), AVSR, indicator organisms and odour, to understand the relationship between these parameters. The final objective was to develop appropriate VSR (%) levels for each STP product using a correlation with AVSR to ensure a stable product, with minimal odours and vector ...

Jun 01, 2021 · Study on the viscosity behavior of oil/water emulsions to facilitate pipeline transport. 40–80% of oil content at 30 °C and 50 °C. Viscosity behavior and stability of emulsion are mainly influenced by oil content and surfactant concentration. 0.5%, 1% and 2% of Emulgen 120 (Poly oxyethylene (13.3) laury l ether) at 30 °C and 75% oil content.

Overview Health effects Environmental effects Sources of emissions References Description The principle end use of acrylamide is in water-soluble polymers used as additives for water treatment, enhanced oil recovery, flocculants, paper making aids, thickeners, soil conditioning agents, sewage and waste treatment, ore processing, and permanent-press fabrics.

Flocculants are applied in potable water, industrial raw and process water, municipal sewage treatment, mineral processing and metallurgy, oil drilling and recovery, and so forth [5–11]. These materials have the ability to induce an advanced coagulation process, after which a large amount of bacteria and viruses from the water are ...

Polymer flooding has been used for more than 40 years to effectively recover the remaining oil from the reservoir, up to 30% of the original oil in place. Due to decreased water production and enhanced oil production, the total cost of using the polymer flooding technique is less than that of …

Jan 01, 2017 · Usual polymer concentration is between 100 and 4200 ppm, but in this work a high concentration was preferred for injection due to the high viscosity of oil and aspects of commercial. After that, two samples were prepared, the polymer concentration effects increment in saline system was checked.

When added to waste water, it causes suspended particles to aggregate and to precipitate. In municipal and industrial waste water treatment it can be used in all liquid-solid separation processes including primary sewage treatment. PAMs are also used to treat water from mineral mining operations. Another common use is oil extraction and recovery.

Tertiary treatment is used at municipal wastewater treatment plants when receiving water conditions or other uses require higher quality effluent than that produced by secondary wastewater treatment. Disinfection for control of pathogenic microorganisms and viruses is the most common type of tertiary treatment.

Treating Fat, Oil and Grease in Wastewater. Fat, oil and grease (FOG) is a by-product of cooking foods such as vegetable oils, meats and dairy products. Food Service Establishments such as restaurants, takeaways and pubs are a prime source of FOG, which can pass into the sewer system during cleaning processes.
