五洲興産ベトナム
In Vietnam, we have designed Wastewater Treatment Projects in a large variety of industrial manufacturing, specialized in electronic devices, automotive components, and rubber products processing… The effluent can meet the highest requirements in treated wastewater discharge of Vietnamese Standard and also be discharged directly to local river/channels without further treatment.
Our wastewater treatment products are as follows:
Physical Chemical Treatment
Heavy metal removal
Keywords: Coprecipitation method, Chelating agent, Metal chelating resin
This is a technology that captures and separates a small amount of residual heavy metals that are difficult to process with ordinary coagulation sedimentation method.
Since Vietnam has strict wastewater standards, it is required that advanced treatment of wastewater discharged from plating and surface treatment processes etc.
Advanced Oxidation Processes (AOPs)
Keywords: Fenton reaction, UV treatment, Ozone treatment, Hydrogen Peroxide
They are technologies that oxidatively decompose complex organic constituents that are difficult to remove by biological treatment. We have some technologies which are highly efficient and minimize the generation of waste sludge.
Coagulation sedimentation / Dissolved Air Flotation
Keywords: DAF, GK-Separator, Coagulation and membrane filtration
We provide highly efficient and compact plants such as GK-Separator improved from existing technologies. We also provide our own technology and new coagulation and membrane filtration system.
Oil Removal
Keywords:Demulsification, Oil separator
We have technologies for breaking emulsions that are difficult to separate, and for decomposing and separating Oils and Fats.
Cyanide removal from wastewater
Keywords: Alkaline-Chlorine Oxidation, Ozonation, Electrolytic Oxidation, Prussian blue method, Metallgesellschaft Natural Resources (MNR) process
We provide treatment processes using cyanide decomposition and immobilization technologies, which is a harmful substance mainly discharged from processes of gold plating and copper cyanide plating.
Filtration
Keywords: Multi Media Filtration, Membrane filtration
We provide the optimum filtration process according to the raw water for filtration and the required water quality.
Adsorption method
Keywords: Activated carbon adsorption, Activated alumina, Zeolite
We provide adsorption treatment for VOC, color, complex COD, etc. by combining activated carbon, activated alumina, zeolite, adsorption resin, etc.
Sludge Thickening / Dewatering
Keywords: GK- Separator, GK-VoluteTM Dewatering Press
“We realize optimization of sludge concentration by sludge thickening technology and provide appropriate dewatering units suitable for the raw water and sludge properties.
We contribute to reduce disposal costs through obtaining dewatered sludge with a low water content.”
Biological Treatment
Methane fermentation treatment
Keywords: GK-UASB, Continuous Stirred Tank Reactor (CSTR), Biogas
In case highly-concentrated organic effluent discharged from food factories etc., biogas technology adopted high loading rate and operated at lower power consumption, such as Upflow Anaerobic Sludge Blanket (UASB) method can contribute to significantly reduce operating costs. We also provide biogas technology for organic solid waste.
Activated sludge treatment
Keywords: Biological Denitrification, Sequencing Batch Reactors (SBR), Biological Aerated Filter (BAF) , Oxidation Ditch
We provide the optimum treatment method from activated sludge, biological denitrification, SBR, or contact oxidation etc., suitable for properties of organic wastewater generated from the production process in factories, restaurants, shopping complex, or domestic wastewater from toilet and kitchen etc.
Advanced biological treatment
Keywords: Membrane Bioreactor (MBR), Moving Bed Biofilm Reactor (MBBR)
It may be difficult to secure the required quality of treated water by conventional aerobic treatment process, in case there is a demand of treated water recycling or necessity of discharge near to water intake. We provide some advanced biological treatment technologies applying Membrane Bioreactor (MBR) and Moving Bed Biofilm Reactor (MBBR) etc.
Others
Deodorizer / Scrubber
Keywords: Soil deodorization, Bio-deodorization tower, Chemical Scrubber, Activated Carbon adsorption tower
In order to properly treat odor generated from wastewater treatment plants and prevent secondary pollution, we provide the optimum deodorization technologies in consideration of the type of odor, surrounding environment and economy.
Environmental monitoring system
Keywords: pH meter, COD meter, Ammonia meter, NOx-N meter, TSS meter, GK-RCMC System
We provide an environmental monitoring system in accordance with the Decree 40/2019/ND-CP on amendments to Decrees on guidelines for the Law on Environment Protection.
In addition, the “GK-RCMC system” developed by our company can also build a remote, centralized monitoring and control system for wastewater treatment plants.
