On August 16, Ho Chi Minh City Export Processing and Industrial Zones Authority (Hepza) said that the unit has just received technology for comprehensive wastewater treatment solution by electro-mechanical technology. According to Mr. Nguyen Hoang Nang – Head of Hepza, this is a very useful solution for businesses in export processing zones and industrial parks to apply new technology in building
wastewater treatment systems of industrial parks , ensuring the technical standards and regulations on environmental protection.
In addition, the amount of sludge generated from the wastewater treatment process can be used as industrial fuel. This wastewater treatment solution uses up to 9 different electro-mechanical and thermo-electric technologies to destroy all chemicals, parasites, bacteria, extract heavy metals by up to 99%, reducing the amount of oxygen needed. providing microorganisms to oxidize organic matter to less than 3% of the original.
In particular, this technology does not use processing chemicals, so the source of waste water outside does not contain pollutants. In the system there is no need to replace the filter, it automatically collects residues and compresses them into an impurity that can be used for burning. Processed, this system collects all of the clean water. Currently, the irrigation side requires businesses to pay an additional discharge fee to the environment, while the medium has to pay for waste water treatment, so it has to pay up to 2 times the charge, so if reusing the source Treated water will not cost this. This technology does not waste land, ”added Mr. Nguyen Hoang Nang.
