Remediation systems

Air Sparging (AS)

The technology involves the insufflation of air into the contaminated aquifer, in correspondence of properly equipped wells.

Effectiveness of Air Sparging
Stripping of volatile compounds
Support for biodegradation reactions

The extraction of insufflated gas usually takes place through the joint action of a system SVE system

BioSlurping (BSL)

The technology allows the recovery of floating product (hydrocarbons) on the groundwater table, by the action performed by a surfasse suction pump.

Benefits of the BioSlurping system
High efficiency purification
Possibility to recover the extracted product
Contextual extraction of interstitial gas

The technology is particularly convenient in case of low aquifer permeability.

BioVenting (BV)

BioVenting involves the insufflation of oxygen in the subsoil, thus favoring the action of bacterial degradation.
Applicability of BioVenting:

High biodegradability of contaminants
Average / slightly cohesive soil

Soil Vapor Extraction (SVE)

This method involves the installation of extraction wells, for the decontamination of polluted vadose zones.
The wells are maintained in depression by the suction of the gas. How does the recovery happen?

Physical extraction of pollutant
Soil oxygenation

Deep LandFarming (DLF) ®

The Deep LandFarming ® is a patented technology by Water & Soil Remediation.

Main features::

Achieving greater depths
Low cost of installation and operation
Easy to implement
Effective on organic compounds
Effective even on surface aquifer

Implementation:

Preliminary dewatering (by draining pipes or wellpoint system)
Preparation of piles and installation of the air injector pipes

Pump & Treat (P&T)

With the Pump & Treat system contaminated water is extracted and subsequently treated.

Benefits of Pump & Treat technology:

Extraction of heterogeneous contaminants
Contamination migration inhibition (hydraulic barrier)
Recovery of treated waste water
