Abstract: The sanitation situation in the remote Villages in the Delta Egypt is becoming not only huge Environmental crises but also a crucial health problem. The problem lies in the rising of G.W.T due to the old used systems of disposal (bottomless cesspool "trench"), the waste water is mixing with the G.W.T and causing its rising to the extent that it floods the streets in some cases. One of the solutions that was considered was stabilization ponds, another was Extended Aeration (activated sludge). As new concept the Japanese university introduced Down Hanging sponge as an experienced solution for the task. For many years, decision makers for sanitation in Egypt built their decision upon initial cost only, neglecting the other long term costs like running cost and operation and maintenance and other factors affecting the treatment processes. Then, when fundamentals of Value Engineering science were introduced, thinking began to change. Now after the development of Environmental Engineering sc

Abstract: Benzimidazole derivatives are crucial structural heterocyclic motifs found in diverse libraries of biologically active compounds which are therapeutically useful agents in drug discovery and medicinal research. 2-(3,5-Dinitrophenyl) benzimidazole, 1 was synthesized by [4+1]-cycloaddition of o-phenylenediamine with 3,5-dinitrobenzoic acid in catalytic amount of NH4Cl. Compound 1 was subsequently utilized as precursor which upon reaction with some halogenated molecular entity furnished the targeted N-substituted-2-(3,5-dinitrophenyl) benzimidazole derivatives in improved yields after reaction optimization engagement. The progress of reaction was monitored with TLC and the chemical structures were confirmed by analytical data and spectroscopic means such as UV, IR, mass spectra, 1H NMR, 13C NMR and DEPT-135. The titled compounds were screened for their antimicrobial activity alongside with gentamicin standard drug, using agar diffusion method while the minimum inhibitory concentration (MI
