16. In-situ chemical oxidation - ISCO
Very fast developing technology of water and soil remediation
New proven and commercially used methods
Most frequently used oxidation agents:
unsaturated zone: H2O2 and ozone
saturated zone: H2O2 and permanganate
Relatively simple methods in terms of chemistry and use

18. Biologically supported reductive dehalogenation
Biologically degradable substrate is fermented by anaerobic micro-organisms => releases H2
H2 is a donor of electron for full dehalogenation of chlorinated ethylenes.
Possible alternate substrates: lactic acid, whey, molasses, vegetable oils, chitin, sugar, ethanol, etc.

19. Example of the dosing system of biodegradable substrate
Semi-automatic dosing system of concentrated agent
Pre-treatment and deoxidizing of water,
Dosing, mixing, infiltration control

20. Chemical in-situ reduction of elementary iron nano-particle
Under strong reduction conditions, water molecule may be reduced:
Aliphatic ClUs (e.g. TCE) are reduced using similar method:
It was laboratory-confirmed that > 70 types of substances may be reduced (Zhang, 2003): TCE, PCE, DDT, PCB, PCM, PCP, lindan, nitrates, Pb, Hg, Ni, Cd, Cr, As, TNT, U……
