Abstract

Many studies have been conducted to investigate the removal of various pollutants from water using nanoparticles. The results indicate that this method has a very high efficiency. In this study, polyurethane filter is modified by nano sized polypyrrole (PPy) and used to improve the quality of the waste water. The chemical polymerization by in place method was used for polymerization of PPy. The Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FT-IR) was used for characterization of morphology, size and porosity of synthesized nano-polymers. The results indicate that the synthesized polymers are granular and uniformly (≈ 50 to 120 nm) synthesized on the polyurethane filter. Central Composite Design (CCD) was used to study the effect of filtration time and filter height on the improving of waste water quality. The quality of waste water after filtration was checked by spectroscopy and various devices such as BOD meters, salinity gauge and so. The results indicate that designed filter has a good performance in improving the parameters such as total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), color, salinity, hardness and pH from waste water. After data modeling, optimal conditions for improving the quality of waste water such as the number of passing waste water samples from filter and filter thickness were obtained using graphical method. The optimum thickness for the filter is 1. 3 centimeters and the most suitable filtration is 8 times.
