“…Limited studies on removal of some pesticides like herbicides (Wang et al 2010;Riungu et al 2012;Hidalgo et al 2013;Musbah et al 2013;Karimi et al 2016); fungicides (Drazevic et al 2013), and insecticides (Pang et al 2010;Karimi et al 2016) have been reported using RO and NF membranes. The thinfilm composite (TFC) polyamide RO membrane prepared on polysulfone support in our laboratory was evaluated for the removal of only two phenyl urea herbicides (Mehta et al 2015(Mehta et al , 2017. Thus, regarding the potential for exposure of multi pesticide residue to water, the present work is aimed to improve the filtration of pesticides from water, which provides challenges to industrial or other users with emerging membrane technologies TFC membrane with cross-flow filtration process and reinforces the engagement between research and application aspects.…”

The study evaluated removal efficiency of 43 pesticides from water by thin-film composite polyamide membrane indigenously prepared by interfacial polymerization of 1,3-phenylenediamine and 1,3,5 trimesoyl chloride coated on asymmetric polysulfone support. Membrane performance was evaluated by gas and liquid chromatography mass spectroscopy determination of multiple pesticides remaining in feed and permeated water following the application of pesticides each @ 0.02, 0.05, and 0.10 mg/L in de-ionized water. The membrane was most efficient in the rejection of persistent organochlorine insecticides, viz. endosulfans (100%), dichlorodiphenyltrichloroethane (95%), and hexachlorocyclohexane (92%). Out of 43 selected pesticides, 33 were removed by > 80%. Size exclusion mass transfer played a significant role for molecules to pass through the membrane as observed for endosulfan isomers, endosulfan sulphate, and difenoconazole with molecular weight > 400. Pesticide rejection was also related to hydrophobicity (Log P). Hydrophobic pesticides with log P > 4.5 were rejected by > 80%, while monocrotophos with less hydrophobicity (log P = − 0.22) exhibited poor rejection (38%). Water flux decreased with an increase in pesticide concentration. The process of pesticide filtration was optimized at 200 psi. The results indicated the potential of the membrane to remove pesticides from water.

“…Polysulfone solution (15% w/w) was prepared by dissolving it in N , N dimethylformamide with stirring at 60–65°C for 6 h. The solution was cast on nonwoven polyester fabric rolled in the prototype casting machine. The prototype casting machine was depicted in our previous study 9 . In this machine, the micrometer is attached to control the thickness of the casting solution layer.…”

The preparative membrane process is a dynamic one and intertwined with the separation arena. As for the progression of technology in membranes, our direction is to prepare polypyrrole interlayer‐based thin‐film composite (TFC) membrane. Polypyrrole shows its attachment ability with polysulfone membranes. The coverings of pores with the polypyrrole entity result in better flux in terms of TFC membranes compared to TFC membranes on polysulfone (Memb‐I). The membranes are characterized by FTIR‐ATR, contact angle, zeta potential, SEM, AFM. Polypyrrole interlayer‐based membrane (Memb‐II) show better flux though it sacrifices salt separation ability compared to Memb‐I. Memb‐II shows a better separation of pesticides (diuron and isoproturon) compared to Memb‐I. Memb‐II provides isoproturon's separation ability (89.52% rejection, 54.9 LMH), whereas, for diuron, it is 78.82%, 53.46 LMH. The antimicrobial property is seen for interlayer polypyrrole‐based TFC membranes.

“…Operating pressures of NF membranes are lower than that of RO membranes and separation by them results from a combination of sieving and Donnan effect. [4] These membranes have versatile applications like water recovery from dye industry effluents, [5] heavy metal recovery, [6] pesticides removal, [7] hardness removal, that is, water softening, [8] desalination, [9] and also in food industries. [10] Nanofiltration membranes are prepared by the interfacial polymerization reaction of difunctional amines with trifunctional acid chlorides on different porous polymeric supports such as polysulfone, polyethersulfone, polyacrylonitrile (PAN), etc.…”

The present work depicts the preparation, characterization, and application of thin film composite nanofiltration (TFCNF) membranes. TFCNF membranes having polyacrylonitrile ultrafiltration support with active layer made of polystyrene sodium sulfonate–polypiperazinetrimesamide semi‐interpenetrating polymer network (semi‐IPN) are prepared. Membranes with semi‐IPN active layer exhibited better hydrophilicity, higher negative zeta potential and surface roughness in comparison with NF membranes having virgin polypiperazinetrimesamide as the active layer. Semi‐IPN membranes exhibited pure water permeability 103 ± 10 LMH at 150 psi pressure and rejection ratio of bivalent to monovalent salts as 2.7, whereas for virgin polypiperazinetrimesamide membrane the values, are 42 ± 5 LMH and 2.1, respectively. The semi‐IPN NF membranes showed better antifouling behavior than the virgin polypiperazinetrimesamide membrane. The flux recovery ratio and total fouling ratio of semi‐IPN NF membrane were observed 97.8 and 3.3% whereas for polypiperazinetrimesamide NF membranes, the values are 90.9 and 10.5%, respectively.
