Azienda Chimica Genovese SRL was constituted in 1947 by Alessandro Doldi in Genoa-Italy, to produce and market a disinfectant agent: Sodium Hypoclorite. He had invented an electrolytic cell, called Doldi cell, in which brine was decomposed into chlorine gas and caustic soda, then they were mixed together to obtain Sodium Hypochlorite at high concentration. This product was sold for general disinfection.

In 1953 ACG built his first direct electrochemical chlorination of water plant for La Spezia Gas & Water Municipal Company. Then several other plants were produced to be used in Aqueducts to make water drinkable (Aqueduct for Italian Navy Arsenal, Brugneto in Genoa, the most important aqueducts in Sardinia and Po Aqueduct in Turin).
In 1954 ACG began the construction of plants for antifouling treatment of seawater circuits on board of ships. In these systems, similar to previous ones, chlorine was obtained from electrolysis of sea salt mixed to water into a cell, directly on board.
First plant began working on 25th June of the same year on M/N Enotria (Adriatica di Navigazione SpA), to prevent the growth of sea organisms in seawater pipes of coolers, condensers, emergency fire systems, sewage water boxes etc.

Thanks to the good results achieved on the first ship, other orders followed from Adriatica di Navigazione and other companies, including Italian Navy.
Till now that plant holds the record for the most successful application of antifouling treatment, its efficacy was immediately appreciated. The ability to eliminate unpleasant odours of hygienic services onboard was, besides, enhanced. During year 1978 ACG began the production of ECOLCELL Antifouling System, fed with seawater instead of sea salt solution, using inside the elctrolytic cell some anodes in graphite. The system operated on the principle of electrolysis: a low voltage was applied to seawater circulation in a cell, producing Sodium Hypochlorite without any addition of chemical products. The resulting solution (at low concentration of Chlorine - 0.1/0.3 ppm) was then injected into seachests and mixed to seawater suctioned by pumps. First of these systems was installed on vessel Carducci (Tirrenia di Navigazione SpA).

The problems caused by marine fouling lead to increase consumption of fuel and heavy maintenance costs.

Antifouling treatment based on electrochlorination has proved to be the most efficient and the most economical: according to reports of some customers the expense of ECOLCELL anitifouling system is amortized after two years and currently it is the only system able to solve completely any problem induced by sea fouling.
To compliment its antifouling systems, ACG expanded its product range to include MARIMPRESS, an impressed current cathodic protection system (ICCP) designed to protect ships' hulls from the harmful effects of marine corrosion. Marimpress makes use of titanium anodes which give the system a life of 10-15 years.
