Ecology(Water Treatment Technology, Friendly To People Environment)
CHEMILES” is the system for Groundwater Treatment without using chemicals and yet serving high quality water in extremely high speed. “CHEMILES” uses no chemicals like Chlorine for oxidation, so not bothered by Chloric acid or Trihalomethane and is friendly to people ＆ environment. Development of unique washing method gives bacteria an also allows optimum treatment condition and an extremely high speed treatment. Saturated level of DO activates the raw water and enable it to reach high iron removal rates up to 40mg/l by Contact Oxidation and Ferric Oxi-Hydroxide Film creation. Sufficient DO also activates bacteria, and removes “Challenging” highly concentrated Manganese and Ammonium nitrogen. Applied Unique WP(Whole ＆ Portion) washing reduce water consumption during back wash. Our WP System also minimizes damage to bacteria performance and stabilize operation.Optimum and flexible design assures economical & high performance.
Raw water quality and treatment volume changes from place to place.Even for such a variety of conditions,“CHEMILES” is flexible to satisfy the requirement.
Nagaoka offers various types of systems as Open Top, Outdoor Column, and RC (Reinforced Concrete) to meet the site requirement.
Optimized and flexible design ensures the cost down of the total water treatment system.
Eliminating unnecessary wastes and efficient and high speed operation is widely requested.
“CHEMILES” provides you with the optimum design and highest efficiency according to respective conditions and requirement.Not only to change the type and shape of system, “CHEMILES” will be designed according to customer requirement using our special technologies for design of filter layer and LV selection.
