Sponsor to Agro’2019 Symposium, Greece
It is an honor for Maezawa Industries, Inc. (Maezawa) to be one of the sponsors of the International Water Association’s Agro 2019 Symposium (IWA Agro 2019) which takes place in Rhodes, Greece, June 19-21, 2019.
Maezawa is going to present its “Oxidation Ditch (OD) nitrogen removal system by dual Dissolved Oxygen (DO) control” and hopes that our technology works for all conference participants to improve wastewater treatments.
The Presentation at IWA Diffuse Pollution Conference
“3rd Regional IWA Diffuse Pollution Conference” was held on November 19-22, 2018 in Chiang Mai, Thailand. At this conference, Dr. Miyoshi presented the research results on industrial water treatment: “Influence of aeration schemes on fouling control in hybrid microfiltration membrane system". The presentation was co-authored by Y. Takahashi, L. Zhang (Maezawa Ind. Inc., Japan), R. Nitisoravut (Sirindhorn International Institute of Technology Thammasat University, Thailand), and C. Polprasert (Thammasat University, Thailand). In this presentation, we reported that the continuous aeration is more economically attractive than intermittent aeration for controlling membrane fouling in our hybrid microfiltration membrane system.
[Announcement] The Presentation at IWA conference about New Membrane Technology
“IWA Regional Conference on Opportunities for Water Reuse in Southeast Asia” will be held at Phuket Thailand Oct. 30 – Nov. 2, 2018. At this conference, we will provide the latest progress on a new membrane system. The title of our presentation is “Energy consumption in baffled membrane bioreactor (B-MBR).”
The B-MBR does not require a recirculation pump and a mixer in the anoxic tank for promoting nitrification and denitrification. Therefore, energy consumptions associated with these apparatuses can be reduced by utilizing the B-MBR concept. In our presentation, the results of the estimation on specific energy consumption during B-MBR operation will be presented.
New Membrane Technologies presented at IWA conference in Singapore
Dr. Miyoshi presented two new membrane technologies at 8th IWA Membrane Technology Conference & Exhibition for Water and Wastewater Treatment and Reuse, which was held 5 September 2017 in Singapore.
One is about industrial water treatment titled: "Treatment of highly-colored surface water by combination of ion exchange and hybrid microfiltration membrane filtration system". The presentation was co-authored by Y. Takahashi, T. Suzuki (Maezawa Ind. Inc., Japan), R. Nitisoravut (Sirindhorn International Institute of Technology Thammasat University, Thailand), and C. Polprasert (Thammasat University, Thailand).
Another is about nitrogen removal from wastewater titled: "Factors affecting nitrogen removal in baffled membrane bioreactor (B-MBR) ". This presentation was co-authored by T. Tsumuraya, T.P. Nguyen (Maezawa Ind. Inc., Japan), and K. Kimura, Y. Watanabe (Hokkaido University, Japan).
Signing Ceremony of the MOU on Cooperation Agreement Extension with Amata Group
On June 20, 2016(Monday), Maezawa signed a MOU to extend "Memorandum of Cooperation on High Quality Water Supply " with Amata Corporation (Amata) and Amata Water, at the Amata Service Center of Amata Nakorn Industrial Estate.
The MOU extends the expiration date of the Agreement from May 2016 to May 2019, aiming to promote the continuation of future cooperation, in order to achieve a high-quality industrial water supply business for Amata Science City, which has been studied thus far.
During the signing ceremony, Maezawa's Managing Director, Mita, reported about the achievements of the last three years. Mr. Viboon Kromadit, Chief Marketing Officer for Amata Corporation, said "We are very happy about the achievements of the study thus far. I believe that the efforts of Amata and Maezawa always succeed." Finally, Maezawa’s President, Matsubara, expressed his aspirations: "Over the past three years, the project has advanced so far as to be considered one step away from realization. In addition, very high evaluation and expectations will have been requested from NEDO, which has provided assistance, we intend to make further efforts toward the commercialization to be implemented during the three-year period of the extension. "
Signing Ceremony of the MOU on Partnership Agreement Extension with SIIT
On June 21, 2016(Tuesday), Maezawa signed a MOU to extend the Memorandum of Understanding on "the Study of High Quality Water Produced by the Hybrid MF Membrane System" with Thammasat University Sirindhorn International Institute of Technology (SIIT). Pursuant to the MOU, the expiration date of the Agreement will be extended to May 2019.
SIIT is collaborating on a survey, and has provided valuable advice based on the latest information concerning the water business in Thailand, for consideration of a high-quality industrial water supply business.
During the greeting session of the signing ceremony, Dr. Somnuk Tangtermsirikul (Professor), Director of SIIT, said "In addition to the joint study that is currently being conducted, we will provide full cooperation for Maezawa’s commercialization study in Thailand, such as cooperation with respect to pilot plant experiments." Maezawa's President, Matsubara, said "We strongly believe that we will continue the existing friendly relationship in the future." Both sides confirmed that they would continue further cooperative efforts.
Agreement on mutual cooperation of "Saitama Overseas Sewerage Association"
On February 24, 2016, Maezawa Industries, Inc. as a member of "Saitama Overseas Sewerage Association” signed an agreement on mutual cooperation among the members: Saitama Prefecture Public Sewerage Works Bureau, The Associated General Contractors of Saitama Japan, Saitama Construction Consultants Technical advancement Association and Saitama Sewerage facility Maintenance Management Association.
The purpose of this association is to promote the project: "The Technical Assistance of Sewerage Technology in Collaboration with Public and Private Sectors in Thailand ". This project is a part of JICA's Partnership Program, and operated by Saitama Prefecture Public Sewerage Works Bureau. The period of the project is from February 24, 2016 to January 31, 2019.
By aggressively joining the activities in Thailand and cooperating with members of this association, we aim to strengthen our overseas business.
