The huge amount of solid waste from the brick manufacturing industry can be used as a cement replacement. However, replacement exceeding 10% causes reduction in strength due to slowing pozzolanic reaction. Therefore, this study, potential is enhanced using ultrafine powder with hydrated lime (HL). A total six self-compacting paste mixes were studied. HL 2.5% by weight binder was added two formulations: and 20% burnt (WBBP), activate An increase water demand setting time observed increasing...

ABSTRACT: Studies were undertaken to determine the role of solution pH and temperature in enhancement adsorptive capacity GAC for phenol ocresol stemming from oxygen‐induced polymerization. Anoxic oxic isotherms sorbates conducted at various pHs temperatures. Adsorption room (21 °C) 3,7, 11. Low favors physical adsorption, measured by anoxic capacity, while 11 promoted The optimum adsorption phenolics under conditions was 7. Isotherms also neutral temperatures 8°, 21°, 35°C. Lower favored...

Abstract Bench scale batch reactors were used to acclimatize and selectively enrich phenol degrading microorganisms, using raw domestic sewage as a seed of heterogeneous culture. During acclimatization process, was the sole carbon source feed concentration varied from 20 mg/l 500 mg/l. After acclimatization, which attested by low effluent (<1 mg/l), samples where taken sludge well bacteriologically analyzed. It found that Pseudomonas aeruginosa be predominant microbail species for...

Abstract Adsorption isotherms for phenol and o‐cresol on activated charcoal at neutral pH several dissolved oxygen concentrations were conducted 23°C. Significant improvement in capacities observed with increasing the two adsorbates. These statistically‐significant additional not due to biological activities but merely surface chemical reactions. The capacity was directly related amount of per unit mass GAC.

Abstract The start‐up of sequencing batch reactors (SBR) for the treatment phenol‐bearing wastewater was achieved in about a week without any seeding, using culture present raw sewage only. mixed liquor suspended solids (MLSS) concentration grown to 3000 mg/1 showing inhibition effects at phenol concentrations as high 800 mg/1. effluent were consistently less than 0.5 during most phase. response SBR shock loadings up 1600 mg/I favorable and over 75% removal maintained hydraulic retention...

In this paper, the primarily focus is to extend concept of Octagonal Neutrosophic Numbers (ONN) since these numbers provide a wide range applications while dealing with more fluctuations in linguistic environment. Firstly, mathematical notions and definitions Linear, Symmetric Asymmetric types are proposed. Secondly, α-Cut defined. Finally, case study done by using TOPSIS technique MCDM.

A mathematical model for sequencing batch reactors (SBR) that takes into account fill and react periods was developed tested against experimental data from the literature. The Monod equation used to describe microbial growth kinetics. proposed predicts time dependent cell substrate concentrations during SBR treatment of wastes. numerical method solve governing equations which comprised nonlinear unsteady‐state ordinary differential equations. Model simulations highlighted importance feed...

In this article, our main focus is to put forward the concept of Cryptography in terms triangular neutrosophic numbers. This kind cryptography really reliable, manual, secure, and based on few simple steps. All encryption decryption are easy proceed (mention below). As we know, Public-key as an indefatigable defender for human privacy use information transfer from ages. various concepts available with regard e.g. Elliptic curve cryptography. TNNC (Triangular numbers cryptography) familiar...
