SAMCO’s ,sulfate removal, process is a membrane process that is used to take out sulfates from the ocean water and/or brine streams. When sulfates are present in crude oil, the bacteria eat the sulfates and break them down into hydrogen sulfide gas. SAMCO can help you efficiently remove these sulfates so the biological activity doesn’t take place. When present … » Read More

Acid mine drainage (AMD) is a dangerous form of pollution characterized by high acidity (pH near 2-3) and substantial quantities of sulfate and soluble metals (Fe, Zn, Cu, Ni, Pb, and Cd ions). The accumulation of sulfate in sediments and aquatic systems causes the release of toxic sulfides that can damage the environment ( Utgikar et al., 2002 ; Ghigliazza et al., 2000 ).
