Aquatech is a leader in the water industry. One of our areas of expertise is Zero Liquid Discharge (ZLD). We have completed over 160 ZLD installations on 6 continents. One of these installations was for Egyptian Ethylene and Derivatives Company (Ethydco) which was the first integrated ZLD plant in Egypt.
The company started to build a 460,000 T/Y ethylene plant and a 20,000 T/Y butadiene extraction plant as part of Ethydco’s petrochemical complex in Alexandria. Ethydco took the initiative to comission a Zero Liquid Discharge plant to optimize a cosistant composite mix of treated effluent and water from Nile River canal. Ethydco chose Aquatech to design and install the plant.
The integrated technology solution provided by Aquatech is a microfiltration system, a High Efficiency Reverse Osmosis (HERO™) system, followed by Fractional Electrodeionization (FEDI™) and brine concentrator, and finally a crystallizer and sludge treatment system. The ZLD plant was installed at Ethydco’s petroleum derivatives manufacturing site in Alexandria. A subsidiary of Egyptian Holding Co. for Petrochemical (ECHEM), Ethydco produces ethylene and other petroleum derivatives at this site. The plant designed and installed by Aquatech treats wastewater from this facility and cooling tower blowdown to get cooling tower makeup water, boiler feed water and achieve Zero Liquid Discharge.
With this plant comissioned in 2015, Ethydco meets all the requisite norms of Zero Liquid Discharge established by the Egyptian government to protect their only life-giving aquifer, The River Nile. The success of this project is keenly viewed by the Egyptian government in this region.
