Inhibition of cells growth was measured by counting the viable cell counts, alteration of permeability was assessed by measuring the leakage of 260 nm absorbing materials and the Methylene Blue Dye.
II.Materials and Methods A.
Then the mixtures were centrifuged (12000g for 15 min at 4°C) and the supernatants were checked for the presence of absorbing materials by reading the absorbance at 260 nm (A260).

Materials Used Soil The soil sample is collected from Chakghat (25.04°N, 81.72°E), Rewa district, Madhya Pradesh and is classified as silt of high compressibility (MH) as per IS 1498 (1970).
The soil sample is collected from a depth of 1m below the ground surface as the top soil is likely to contain organic matter and other foreign materials.
Thus it is concluded that combination of geogrid and geotextile can be used effectively in pavement and embankment construction on soft soils, saving costly base and sub-base aggregate materials and prevents lateral spreading of soil.

Micro-electrolysis method can treat wastes with processes of wastes against one another because its raw material is abandoned scrap iron, the generated Fe2+ in the micro electrolytic process can act as the raw material of the Fenton oxidation process and the PH requested by micro electrolysis process and Fenton oxidation process are almost same, thus the collocational method of the two methods can save the acid and alkali used in the adjustment process of pH .
Experimental materials and methods Wastewater The water sample used in the experiment was from the medium pulping stage of a paper mill in Shandong province, the quality of the wastewater was as follows: Chrominance was 240 times, COD was 1360 mg·L-1 and pH was 6.
