“…Laboratory tests and field demonstrations of ISCO technology began in the 1990s. The results were published in numerous articles, reports, and books (e.g., [5,12,[27][28][29][30][31][32][33][34][35][36][37][38]). In parallel to the experiments and based on their results, numerical simulations were developed.…”

This article describes a tool that can be used to improve the effectiveness of the ISCO (in situ chemical oxidation) method. It is an Excel-based application that uses Visual Basic, PHREEQC, and Python. The main functions are feedback control solutions. There are several ideas that can optimise ISCO treatment when using the geochemical model: (i) looping real-time data into the geochemical model and using them to estimate the actual rate, (ii) using spatial distribution maps for delineating zones that are susceptible or resistant to oxidation, (iii) visualising the permanganate consumption that could indicate the right time for further action, and (iv) using alarm reports of the abnormal physico-chemical conditions that jeopardise successful injection.

“…Ammonium persulfate ((NH 4 ) 2 S 2 O 8 ) exhibiting strong oxidizing property is widely used as oxidizing and bleaching agents in the wastewater treatment, detergents, electronics and chemical industries and as an initiator agent in the organic synthesis industries. 1 Ammonium persulfate is mainly manufactured electrochemically by ion exchange membrane electrolysis of ammonium sulfate at the industrial scale: 2 Anode reaction :…”
