Abstract:

Poly(diallyldimethylammonium chloride) (polyDADMAC) has been shown to be an important precursor of the probable human carcinogen N -nitrosodimethylamine (NDMA) when in contact with chloramine. In this study, we conducted an orthogonal experiment design to evaluate the effects of pH values, ammonia, bromide, natural organic matter (NOM) and monochloramine dosages on the formation of NDMA from polyDADMAC during chloramination. Meanwhile, single-factor experiments of pH, bromide and NOM prove the results of orthogonal experiment. The results supported that pH was the most critical factor affectin

Abstract:

AbstractMicrofibrillated cellulose (MFC) preparation was investigated by means of cellulase pretreatment aided by poly(dimethyldiallylammonium chloride) (polyDADMAC) as an additive. The effect of polyDADMAC on the adsorption of cellulase onto the cellulose fibers, and the properties of MFC and MFC films are described. The additive improved the adsorption of cellulase onto cellulose fibers. Compared to the control, at an addition level of polyDADMAC of 0.789 ml g−1, the crystallinity, aspect ratio, the specific surface area of MFC and, the elongation at break and tensile strength of MFC films a

Abstract:

Batik wastewater treatment using PAC (Poly Aluminium Chloride) as a coagulant and organoclay (montmorillonite- polyDADMAC) as flocculants was investigated in this study. The purpose of this study was to analyze the quality of batik wastewater effluent before and after coagulation-flocculation and analyze the effectiveness of organoclay as flocculants of batik wastewater. Organoclay (montmorillonite-polyDADMAC) synthesised by reacting natural bentonite with polyDADMAC 0.4%. Coagulation and flocculation used jar test method with a speed stirring at 120 rpm for 2 minutes and slow stirring at 40 r

Abstract:

Results on the applicability of microwave assisted synthesized poly(diallyldimethyl ammonium chloride) (polyDADMAC) in reactive dye containing textile wastewater treatment are reported. Diallyldimethylammonium chloride and poly(diallyldimethylammonium chloride) have been characterized by spectral means. The microwave assisted synthesized polyDADMAC has shown some effectiveness in textile wastewater treatment. COD removal efficiency of actual textile wastewater is below 30% whereas the standard dye sample shows about 50-60% COD removal efficiency. TDS and TSS also decreased after treatment of t

Abstract:

Abstract Polydiallyldimethylammonium chloride (polyDADMAC) and epichlorohydrin-dimethylamine (Epi-DMA) stock olutions were prepared, stored for varying amounts of time, and used in bench-scale simulations of coagulation/flocculation/sedimentation to determine whether polymer stock age had an influence on NDMA yields. Stock solution ages ranged from under one hour to fifty hours. PolyDADMAC stock age did not significantly affect NDMA production. Epi-DMA stock age significantly increased NDMA production over a time span of 0 to 5 hours, but not from 5 to 50 hours. The relationship between the ch

Abstract:

Due to the large amounts of freshwater consumed in Egypt by the agricultural sector that is more than 85% of Egypt share of freshwater in addition to the high concentrations of salts, chemicals and nutrients produced from fertilizers. Reduction of these pollutants concentrations to an acceptable level and breaking the sedimentation stability of colloidal substances and organic particles for reuse for irrigation purposes was associated with the application of biological treatment with coagulants addition. The flocculation process was performed by using polydiallyldimethylammonium chloride (poly

Abstract:

Palm oil mill effluent (POME) which is mainly associated with lignin has becoming a major concern due to its highly coloured appearance. The main colourant, i.e. lignin particles are difficult to be degraded in oil palm conventional biological ponding system. Coagulation/flocculation could remove the lignin prior to biological treatment and is considered vital to minimize the recalcitrance nature of palm oil mill effluent particles. In this study, the coagulation/flocculation process was investigated to remove lignin particles from aqueous solution. A non-toxic and biodegradable chemical i.e.
