KLD-C MPA (COD, TOC, BOD, PO₄, NH₃-N, SiO₃ & optional EC/PH/ORP/TS/SS/DO) is an automatic on-line analyzer independently developed by Xiamen Kelungde Env. Engineering Co.,Ltd. Using imported CPU, highly precise signal processor and simple but steady hydraulic system to effectively reduce signal fluctuation and to ensure the accuracy and stability of data. Complete separation between electronics and hydraulics allows long-term & stable running. It is suitable for several types of water matrix like river water, surface water and industrial effluent.

Features

1.Robust & Reliable

    Designed for on-line industrial and environmental applications. Complete separation between electronics and hydraulics allows long-term stable operations.

2.Precise Reagent Dosage

    CPU controlled photoelectric dosing system for accurate reagent dosage. Simple & steady structure ensures long-term service life.

3.Easy Installation

    Delivered after a long & successful series of factory tests, it is ready for installation and setup. To start monitoring just need to connect reagent tubes, sample tube, water tube, waste tube and power supply, then set up the parameters.

4.Automatic Calibration

    The analyzer performs calibration according to the calibration interval and type set up by users. If the result exceeds selected limits, the original calibration parameters will not be updated and an alarm signal will be outputted.

5.Automatic Monitoring

    Measuring interval can be freely set up by users. Between two measurements the analyzer remains in standby.

Measuring Principle

TOC&COD&BOD (UV Method)

    According to the ultraviolet light absorption effect of unsaturated organic molecules at particular wavelength , and then calculated by law of Lambert-Beer. Usually a sample is a mixture of many different molecules to form an average absorption coefficient. The instrument must be calibrated by using laboratory-calibrated TOC/COD/BOD values before use. Also, the proportions of the different molecules should be kept approximately constant to ensure good TOC/COD/BOD correlation. SAC UV absorption method is fast, reliable, low input & maintenance.

Phosphat

    The sample after proper filtration is pumped into reactor, where molybdate is injected to form phosphorus-molybdenum heteropoly acid. Then to inject ascorbic acid into the sample. After fully mixing and reaction, the analyzer measures ABS value of blue substances produced by reaction at the specific wavelength, then calculates sample concentration according to the stored calibration data.

Silicate

    The sample after proper filtration is pumped into reactor, where molybdate is injected to form silico-molybdic heteropoly acid. Then to inject oxalic acid and 4-Methylaminophenol sulfate-sodium sulfite solution into the sample. Oxalic acid is used to minimize the phosphate interference. After fully mixing and reaction, the analyzer measures ABS value of blue substances produced by reaction at 810nm, then calculates sample concentration according to the stored calibration data.

Ammonia (Gas Sensoring Electrode Method)

    The sample after proper filtration is pumped into reactor, Inject reagent to adjust PH value over 12, which will convert all ammonium ion into ammonia which penetrates through electrode membrane. The variation of electrode potential and ammonia value changed in logarithm relation and then calculate the sample concentration.
