A Study of Polyacrylamide Based Gels Crosslinked With
We report a comparative study of two water control gel systems, i.e., polyacrylamide tertiary butyl acrylate copolymer (PAtBA) and polyacrylamide homopolymer (PAM) crosslinked with polyethyleneimine (PEI). Several techniques were used in the present study, including: Gas Chromatography (GC), C13 Nuclear Magnetic Resonance Spectroscopy (C13 NMR

Comparative study on the effectiveness of hydrophobically
Comparative study on the effectiveness of hydrophobically modified cationic polyacrylamide groups in the flocculation of kaolin. The molecular weight of the hydrophobically modified copolymers is lower than the homopolymer due to the reduction of the intramolecular interactions in the dilute regions

Study on sodium and potassium salts of polyacrylic acid as
comparative study 7 of PAM and homopolymer of acrylonitrile (PAN) as antiscaling agents showed that with increase in the amount of polymers concentration in water, the salt deposition on vessel decreases. PAN gives more effective results over PAM for longer time. The formation of calcium sulphate and carbonate scale

Molecular approaches to determine the multiplicity
Multiplicity of infection (MOI), also termed complexity of infection (COI), is defined as the number of genetically distinct parasite strains co-infecting a single host, which is an important indicator of malaria epidemiology. PCR-based genotyping often underestimates MOI. Next generation sequencing technologies provide much more accurate and genome-wide characterization of polyclonal infections.

- Why is water treated with coagulation and flocculation?
- Before we look in detail at the coagulation and flocculation process, you might be wondering – why is water treated with this method?
- The main purpose of coagulation and flocculation is to treat turbid (hazy or cloudy) water, thus improving water quality.
- What is coagulation & flocculation?
- The main purpose of coagulation and flocculation is to treat turbid (hazy or cloudy) water, thus improving water quality. This is especially key for wastewater treatment, and can reduce organic loads and suspended solids by up to 90%. Suspended solids are commonly found in the majority of surface water supplies and all wastewater supplies.
- How does coagulation & flocculation reduce water turbidity?
- By reducing water’s turbidity, coagulation/flocculation minimizes the amount of chlorine (or similar disinfection chemicals) that must be added to the water, helping to save money and make the water safer. Let’s take a look at the coagulation and flocculation processes in more detail. How Does Coagulation Work?
- What is coagulation in water treatment?
- Although coagulation is a water treatment technology with a long history and the coagulation of the most typical surface water impurities by traditional coagulants might be considered well described, coagulation is still a subject of ongoing investigation.
