A method for purifying waste water from heavy metals using of diatom algae was developed by scientists of the East Kazakhstan State Technical University named after Serikbaev, Tengrinews.kz reports citing the press service of JSC "National Center for Scientific and Technical Information". Algae, by which wastewater treatment are produced, are common in waters of the Eastern Kazakhstan.

Diatoms algae reproduce well in water bodies of Kazakhstan and are quite capable bind salts of mercury, cobalt, manganese, copper and zinc, says Vice-Rector for Science and International Cooperation EKSTU named Serikbaev, Candidate of science (Geology and mineralogy) Oleg Gavrilenko. Pantsir capable of include salts of radioactive elements. Completely replace the chemical methods of wastewater treatment using algae is hardly possible, but the method can be an important part of the process, said the scientist.

The project was funded by the state scientific and technical program. Technology has been successfully was tested and implemented at the landfill, which carried out sewage LLP "Kazzinc". The possibility of using of algae at settling ponds of concentrating factories. In some regions of Kazakhstan pollution by heavy metals reaches a critical level. According to the Regional Center for Ecological Security in 2013 in some areas of the Ust-Kamenogorsk content of cadmium in soil exceeded the maximum allowable concentration of 40-60 times, lead - 20 times, copper - in the 30-90 times, zinc - 15 times . The zinc content in the waters of the rivers Ulba and Irtysh in the city reaches 7.3 MPC, copper - up to 7 MAC.
