TPNA-500 Automatic Total Nitrogen/Phosphorus Monitoring

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.

Reduction in Life Cycle Cost (LCC)

 

Segment: Process And Environment
Division: Water Pollution
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

 

  • Adoption of stain resistant measurement system
    While adopting a reduced reagent volume (1/10) realized by our conventional
    model, employing a new measurement method (meniscus measurement
    method) and enhanced automatic washing functions (optional) have been
    achieved, contributing to lengthening the maintenance cycle.
  • Reduction in power consumption by approximately 30%,
    and pure water and waste water to 1/2

    We have reduced the cost for electricity, use of pure water and waste water
    treatment (including labor) as well as environmental burden (as compared
    with our conventional product).
  • A variety of washing functions
    sampling point backwash purge function,
    line washing function during reagent change, automatic sample line
    washing function*2
  • Ultraviolet oxidation decomposition method
    Domestic market share of approximately 60%. No. 1 in the industry*3
  • Color touch panel
    Improved visibility and operability.
  • A built-in load volume operation function
  • USB data output port

*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.
