Definition - What does Amoeba mean?
An amoeba is a small, single-celled organism or protozoan. Amoebas cause microbial or bio corrosion.
Amoebas and single-cell bacteria cause biofilm inside of pipes. They can be eliminated by the penetrating capability of super-saturated water.
Microbial corrosion or biological corrosion are caused by amoebas. In acid drainage dumps, amoebas cause leaching.
Corrosionpedia explains Amoeba
An amoeba is a microbe that can be found practically everywhere, in oceans, lakes, rivers and any natural waters, acid drain dumps and even in the air. When they run out of food, colonies of amoebas move to areas where food is more plentiful.
They are frequently implicated in accelerated corrosion of steel and non-ferrous metals. Corrosion of coating layers is also caused by amoeba effect.
Amoebas like acanthamoebae are ubiquitous in tap water. In most instances the number of amoebas present is not significant, but they proliferate in stagnant, residual water and then become dangerous.
Amoebas can be controlled by chlorination of the water (with a free residual of 25 ppm). However, corrosion of equipment may occur in stainless steel where amoebas are removed by chlorination from water.
