Biodegradation: Biodegradation of Dimethoate in Industrial Effluents by...

In gpk: 100 Data Sets for Statistics Education

Description

Industrial effluents may contain large amounts of toxic material. This material can cause hazard to birds, fish etc. Scientists make efforts to remove such toxic material from flowing waters. Biodegradation by microorganisms is one of the ways. Parameters likely to promote microbial growth (and in turn cause more degradation of toxic material) include pH, ambient temperature, inoculum size and stirring. A $2^4$ experiment was conducted. The data give results of this experiment. Objective is to find conditions, which will cause maximum removal (maximum growth).

Usage

data(Biodegradation)

Format

A data frame with 16 observations on the following 5 variables.

pH

pH level

Temp

Temperature

Inoculum

Inoculum at two levels

Aeration

Aeration at two levels No Yes

Percent.Removal

Response (% removal of the Dimethoate)

Details

Build a factorial experiment model for the data set and evaluate for the interaction effect.
