Water Treatment

Contaminated Groundwater

This usually occurs as a result of a former industrial process eg. gas works, solvent manufacturing or use, oil storage, rail depots or an accidental spillage.

Groundwater and water, contaminated or not, on and under former industrial sites can pose serious problems to their clean up and future use both in terms of the possible costs involved and the practicalities of carrying out remediation work.

A wide range of contamination may be encountered in water including oils, phenols, polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), solvents, pesticides, heavy metals, cyanide and arsenic compounds, all of which we successfully reduce to acceptable limits.

Contaminated Waste Streams

Industrial effluent is subject to changing legislation, rising effluent discharge costs and increasingly stringent discharge consent levels. Cognition Land and Water Limited can design and build continuous automated treatment systems that:

Contamination of lakes, streams and ponds is usually the result of accidental discharge from manufacturing plants, static storage tanks or tankers. This includes the clean up of:

Mobile Plant

Biological treatment units

These are modular and can be made available at very short notice. The type and size of plant mobilised varies depending on the type of contamination encountered.
