Removal of anionic and nonionic surfactants in a
Removal of anionic and nonionic surfactants in a wastewater treatment plant with anaerobic digestion. A comparative study. The elimination of the surfactants in water, suspended solids and sludges were determined in the different stages of the purification process. The results obtained show that over 90% of the surfactants were eliminated.
Research shows that the coagulation of industrial wastewater is an effective method of removing anionic surfactants (Aboulhassan et al. 2006; Mahvi et al. 2004). Coagulation in this case involves
Monitoring of Anionic Surfactants in a Wastewater
Evaluation of anionic surfactant (AS) quantities in the environment has been the subject of intensive worldwide investigation. Even so, significant questions related to their presence in Algerian wastewaters discharged into the Mediterranean Sea remain. For the first time, monitoring of AS in a wastewater treatment plant (WWTP) located about 30 km west of Algiers was carried out.
JSD publishes basic and applied scientific research related to the interfacial behavior of petrochemical and oleochemical surfactants and detergent ingredients and how this relates to performance in different applications.
Removal of anionic and nonionic surfactants in a
On the other hand, little information exists about the simultaneous elimination of anionic and nonionic surfactants in the various stages of the purification processes. This paper presents the results of a complete, comparative study of the removal of LAS and nonionic surfactants in the wastewater treatment plant (WWTP) in Alicante.
Surfactants are considered emerging contaminants, that can represent a source of problems for environment and human health. This paper aims to quantify the effect of a thermophilic aerobic membrane reactor (TAMR), nanofiltration (NF) and adsorption on activated carbon (AC) for the removal of non-ionic surfactants (TAS) and anionic surfactants (MBAS) from a real laundry wastewater.
THE EFFECT OF SURFACTANTS ON ACTIVATED SLUDGE PROCESS
The effect of anionic surfactant sodium dodecylbenzene sulphonate (SDBS) on biological treatment of wastewater was investigated. The activated sludge method was applied.
In this study, anionic surfactants concentrations and other physico-chemical parameters of surface water quality were assessed in the water of M’Koa Lake in the city of Jacqueville (Côte d’Ivoire). Three sampling campaigns were conducted at different seasons at six (6) sampling stations, identified in M’koa Lake by taking into account potential sources of pollution.

OSTI.GOV Journal Article: Effect of waste water treatment technology on the elimination of anionic surfactants
surfactant in wastewater treatment is investigated. 1.3 Objective and Scope of Study The scope of this report is to remove surfactants on wastewater by batch froth flotation. It is necessary to study the properties of surfactant to evaluate its removal effectiveness on wastewater. It is in the interest of this project to understand the operations

In wastewater treatment, flocculation is a widely used solid/liquid separation technique, which typically employs a charged polymer, a polyelectrolyte (PEL). Polyelectrolytes features, such as charge type, charge density and molecular weight, are essential parameters affecting the mechanism of flocculation and subsequent floc sedimentation. The effectiveness of the process is also influenced
The average concentration of non-ionic and anionic surfactants in the influent to the local WWTP were 7 and 8.7 mg/L, respectively. Removal of 67% to 90% of the non-ionic and 93-99% of the anionic surfactants tested were measured. All surfactants tested showed inhibitory effects both on OUR and nitrification.
- What is partially hydrolyzed polyacrylamide (PHPA)?
- Partially hydrolyzed polyacrylamide (PHPA), consisting of neutral acrylamide and anionic acrylate groups, is suitable for use in water with <25,000 mg/L TDS 12, 15.
- How does PHPA affect fluid rheology?
- The introduction of higher molecular weight synthetic polymers typified by partially hydrolysed polyacrylamide (PHPA) allowed the same effect on fluid rheology to be achieved at much lower additive concentrations, a major practical advantage.
- What is partial hydrolyzed polyacrylamide (HPAM)?
- Partially hydrolyzed polyacrylamide (HPAM) is a water-soluble polymer material used in oil fields [ 18, 19 ]. It usually has a linear structure with high molecular weight [ 20] and is obtained by partial hydrolysis of PAM or by copolymerization of sodium acrylate with acrylamide [ 21 ].
- How phpam is used in water management?
- It involves pumping of polymer, crosslinker and some other additives into the reservoir formation which will afterward form a gel by crosslinking reaction. For example, partially hydrolyzed polyacrylamide (PHPAM) is one of the most-used types of polymer to generate the gel for the water management which has wide applications in the industry .
