AEROBIC
Describes oxygenated water or bacteria which require oxygen to survive.
ANAEROBIC
Describes water which contains little or no oxygen, or bacteria which favour this environment.
BICHEM™
Selectively adapted proprietary bacterial cultures used to seed biological treatment plants. Can be used to start up a new plant or re-seed where the biomass has died off. There is a large range of bacterial blends targeted for different pollutants.
BIOMASS
Refers to the microbes responsible for breaking down the pollutants in a waste water treatment plant.
BOD - Biochemical Oxygen Demand
A measure of the biodegradable pollutant loading in a sample.
COD - Chemical Oxygen Demand
A measure of the total amount of pollutant material in a sample.
DAF - Dissolved Air Flotation
Type of primary treatment plant which removes suspended solids through a flotation process.
DIRECT SOIL INJECTION
A process of breaking down pollutants by direct injection into a specially prepared soil site.
DO - Dissolved Oxygen
FLOCCULANT
A range of chemicals used to enhance flotation and/or settling of suspended solids.
HYDRAULIC FLOW / LOADING
A measure of the total amount of water passing through a waste water system.
pH - potential of Hydrogen
A measure of a solution's acidity (<7) or alkalinity (>7).
POLYMER
A range of highly viscous chemicals used to enhance flotation or settling of suspended solids. Often used in conjunction with flocculants.
REFRACTORY
Refers to non biodegradable pollutants
