Automatic Total Nitrogen/Phosphorus Monitoring
More than 10 years have passed since the 5th Water Use Regulation was enforced in 2001. From the perspective on preservation of ambient water quality, it has become a matter of course for companies to be compliant with regulations and observe corporate compliance. Total nitrogen and total phosphorus monitoring in the future has the potential to lead to proactive enhancement of corporate value, in addition to compliance with regulations. While we propose technological innovations and improvements and LCC*1 reductions, we will pursue the future where regulations are strictly observed and corporate value is improved through monitoring.
1 Reduction in Life Cycle Cost (LCC)
*1_Life Cycle Cost (LCC): Total cost required from purchase to disposal of a product. Total sum of product cost, installation cost, utility cost (electricity and water), running cost (reagent, waste water treatment, parts and man-hours), maintenance cost (regular overhauls and irregular man-hours), dismantling cost, disposal cost, etc.
*2_Hydraulic acid washing is optional.
*3_As of November, 2013. Based on our company's research.
