Thank you for viewing. A textbook that clearly explains the basics of water treatment technology. - Title: Understanding Water Treatment Technology - Author: Kurita Water Industries Ltd. - Publisher: Nihon Suishori Co., Ltd. - Price: 1400 yen I purchased this when studying for the Professional Engineer exam. There is no writing in it, and it has been stored on my bookshelf at home, so I think it's in good condition. Please understand that this is a used book before purchasing. I am also selling other books related to the Professional Engineer exam and sanitary engineering. Bulk purchases are welcome. If you have any questions, please comment. Please read my profile. Thank you. #ProfessionalEngineer #SanitaryEngineering #Engineering
