Ph.D Thesis Title

Study of hydrodynamics and residence time distribution of activated sludge process

Department of Chemical Engineering, Thapar University, Patiala-147004, Punjab, India


In the last few decades the importance of water has been recognized by the industries and wise handling of the effluent has become the outmost necessity. As for the existing treatment plants it is hard to suddenly switch to completely newly introduced treatment technologies improving the existing setup is more convenient as well as economical. Conventional wastewater treatment method like ASP are very common in industries with high organic load in the generated effluent. Radiotracer technique is a simple yet effective way to determine the hydrodynamic efficiency of complex processes like ASP. The radiotracer studies and modelling performed on the ASP help in detecting possible anomalies in the system, hence improving the treatment efficiency. The mixing pattern observed in the aeration tank can determine the optimum amount of aeration needed for the given effluent, hence decreasing the cost of aeration and making the system more economical. The RTD study on clarifier also predict the settling properties of the secondary clarifier. The motivation of the study was to enhance the performance of the existing industrial ASP system and use the similar conditions in a pilot scale reactor to optimize the performance and predict the best working parameters at which maximum treatment efficiency can be obtained.

The overall objective of the present work is to conduct RTD studies of activated sludge process.

To study performance of activated sludge process (ASP) using RTD of aeration tank,

secondary clarifier and complete activated sludge process under different operating condition.

To identify flow anomalies present in the system based on the obtained RTD data.

To develop suitable hydrodynamic model fitting well for the system.

The aim of this project was to develop a low cost strategy to fight the problem of iron deficiency and hence develop an iron doped gelatin gel. The gelatin gel (undoped and doped) were prepared at selected concentration level and were characterized by different rheological technique. The behavior of gel samples in terms of iron release properties were studied at selected pH conditions (pH 3 and pH 7). In experimental procedure, release profile of iron and its subsequent conversion (from (Fe+2 to Fe+3) were studied with gel samples prepared at different concentration level. The focus of the work was food based iron doped gel where understanding rheology is critical in optimizing stability and nutrient release characteristics of the model gelatin gel. Rheological tests on the gelatin gels were performed by Anton Paar MCR 102 rheometer with a parallel plate geometry (25mm). The absorbance of the samples are recorded from U V visible spectrophotometer (Systronics, India) at wavelength 512 nm and 396 nm and corresponding concentrations were calculated using the standard curve. The process of drug dissolution form the gel matrix is important to understand its bioavailability in the body. Suitable dissolution characteristics are important to ensure that the drug will achieve the desired therapeutic effects. Drug release from gel matrix may involve processes that simultaneously involves swelling, diffusion, erosion, and leaching or dissolution. Release study of the doped gelatin was done in pH 3 and pH 7 to obtain the amount of iron release as Fe+2 and study its oxidation into Fe+3 state as the release study was carried out in aerobic (in presence of oxygen). To understand this phenomenon the release data was fitted in various developed empirical models.
