sludge: Sludge

In clayford/dvdata: Data Files for Design and Analysis of Experiments (Dean & Voss)

Description

An experiment that investigates the effect of several factors on the removal of biochemical oxygen demand from wastewater. (Chapter 15, Table 15.8)

Usage

sludge

Format

A data frame with 8 rows and 6 variables:

A

reactor biomass concentration - 2 levels (3000 or 6000 mg/l)

B

clarifier biomass concentration - 2 levels (8000 or 12000 mg/l)

C

waste sludge flow rate - 2 levels (78.5 or 940 m^3/d)

D

biological growth rate constant - 2 levels (0.040 and 0.075 d^-1)

E

fraction of food to biomass - 2 levels (0.4 or 0.8 kg/kg)

Y

removal of biochemical oxygen demand
