The potential use of fresh water algae Chlorella to sorb lead ions from wastewater was evaluated in this study. Fourier transform infra-red analysis of algal species revealed the presence of amino, carboxylic, hydroxyl and carbonyl groups, which were responsible for biosorption of lead ions. Batch sorption experiments were performed to determine the effects(More)
Concrete when exposed to elevated temperature, mechanical properties gets reduced which results in structural failure. The strength of concrete is improved by means of addition of pozzolonic material. Pozzolonic material reduces the pores in the concrete structure and hence improves durability. Here, flyash is added as it facilitates the replacement of(More)
Mathematical models for the surface area of secondary clarifier were developed for wastewater generated from a dairy industry and from domestic sources, by correlating the parameters namely, surface area per unit flow rate (A/Q), influent concentration (C(O)), underflow concentration (C(U)), recycling ratio (r) and Mean Cell Residence Time (theta C) using(More)
The activated sludge process facilitates the removal of carbonaceous BOD, the coagulation of colloidal solids and the stabilization of organic matter by a variety of microorganisms (principally bacteria). Bacillus sporogenes is one of the predominant bacteria found in dairy waste water. The bacteria Bacillus .sp was isolated from the dairy wastewater and(More)
Target recognition is the most challenging problem for missile defense. For accurate target recognition discriminant features must be extracted from the target signature. To extract suitable features an optimized waveform is needed which can be generated using pulse compression techniques. Pulse compression is a technique which can be generally used for(More)
Hindered batch settling experiments were performed on activated sludge generated from dairy wastewater and combined (Dairy-Domestic mixture 1:3) wastewater for different initial Mixed Liquor Suspended Solids (MLSS) concentrations from 2g/L to 20 g/L for varied Mean Cell Residence Time (MCRT) for 5 to 15 days. Bio kinetic coefficients of combined wastewater(More)
