Groundwater remediation

During Remediation of contaminated groundwater, DEKONTA specialists usually apply one of the following procedures:


Pumping and cleaning of groundwater Contaminated water is pumped by submerged, horizontal or other pumps from suitably situated and equipped bores and then is cleaned by means of physical, chemical and/or biological methods. In the case of DEKONTA, it mainly concerns removing dirt in various types of sedimentation tanks and filters; separation of liquid phases in gravitation separators; collection of organic substances or heavy metals in absorption filters with fillers of suitable sorbents (active coal, fibroil, metalsorbents, etc.); removing volatile organic substances in stripping columns and horizontal aerating devices; degradation of organic contaminants in bioreactors of various volumes and designs; neutralisation and hardening of toxic substances in flow reactors.


Biological cleaning. The method of biological degradation of organic contaminants can be successfully applied also during remediation of groundwater, to which suitable bacterial strains, nutrients and oxygen are added.


Monitored and supported natural attenuation. Attenuation concerns a modern approach to decontamination of some types of contaminated areas and is based on monitoring and/or supporting of natural processes directed to decreasing contamination in a locality (natural biodegradation, dilution, sorption, etc.). This method is not suitable in the case that contamination of the locality represents an acute ecological and/or health risk.
