1 Technical Information Manganese Analyser Compact photometric analysis system for manganese measurement in drinking water and wastewater Application In soil, manganese is often found as brownstone. With changing ground water level, water-soluble manganese compounds are formed due to microbial processes. Manganese monitoring in drinking water treatment plants Precipitant monitoring after aeration and filtration processes in drinking water and wastewater treatment plants Your benefits Stainless steel or glass-fibre reinforced carbon housing available Two channel version available Measured value storage using integrated data logger Automatic calibration and self-cleaning Free selectable measuring, cleaning and calibration intervals TI6C/07/en/0.0 06

2 Function and system design Measuring principle After sample conditioning, the analyser sample pump conveys a part of the filtrate to a mixing vessel. The reagent pump adds reagent at a specific ratio. As a result of the reaction, the sample turns a characteristic colour. The photometer determines the sample s absorption of an emitted light at a specific wavelength (s. Fig., Pos. ). The wavelength is parameter specific. The absorbance is proportional to the concentration of the specified parameter in the sample (Pos. ). Additionally, the absorption of a reference light is determined to receive a genuine measuring result. The reference signal is subtracted from the measuring signal to prevent any effects due to turbidity, contamination and ageing of the LEDs. The temperature in the photometer is controlled thermostatically so that the reaction is reproducible and takes place within a short period of time. Reference LED Emitter LED Sample Reference detector Measuring detector Photometric principle a0006 Manganese Photometric manganese determination Interferences Manganese is the second most common heavy metal in the earth's crust after iron. It is also contained in many iron ores. Manganese is often present in the ground as manganese ore. The manganese ore becomes water soluble through the action of air as the ground water level varies. Manganese, in normal concentrations as found in water, is not damaging to the health. It is an important trace element for plants. There are no limit values in wastewater while for drinking water there is the limit value of 0.0 mg/litre, since higher concentrations in water lead to odour, colouring, turbidity and fine grained build-up. Dairies require manganese-free water. Leuco malachite method In the presence of manganese, the reagent indicator turns the sample colour to green-blue. The absorption is determined at a wavelength of 6 nm. The absorption intensity is proportional to the manganese concentration in the sample. The reference wavelength is 880 nm. No interferences up to the given concentration: Concentration [mg/l] Interference 00,000 Mg + 70,000 Cl,000 SO 700 Ca + (as CaCO ) 0 Zn + Fe +, Fe + " Caution! Amines, aldehydes and alcohols interfer in any concentration. Strongly buffered samples or extreme ph values may exceed the buffer capacity of the reagent. Endress+Hauser

3 Sample conditioning Micro/ultrafiltration (Stamoclean CAT0, optional) A membrane filter element is suspended directly into the wastewater basin or channel. A hose pump is located in a pump box on the basin rim.the pump creates a vacuum between the membrane and the carrier plate of the filter element. This vacuum makes the filtrate pass through the filter membrane. Suspended materials, particles, algae and bacteria are collected on the surface of the membrane. Due to alternating pumping and pause, intervals of more than one month are achieved between cleaning cycles. Parallel connection of two or four filter elements increases the sampling quantity up to approx. l/h. The hose pump pressure transports the sample to a collecting vessel near the analyzer over a distance of 0 m. For distances up to 00 m the sample is transported to the collecting vessel by means of compressed air. The analyzers suck the needed sample volume from the collecting vessel. Membrane filtration (Stamoclean CAT, optional) A sample flow of 0.8 to.8 m /h is continuously conducted through the micro filter via a pressure pipe. A part of the sample passes the filter membrane and is then conveyed to the measuring device as filtrate. Sampling is based on the cross flow filtration principle. The PTFE filter membrane separates particles with sizes > 0. µm from the filtrate. These particles are collected in front of the membrane and are washed away with the sample flow. The medium is conducted in a meander-like channel through the filter element. This results in a constantly high flow rate. The high flow rate generates the self cleaning effect. Therefore, mechanical drives for the generation of a flow at the filter surface are not necessary. Backwash filter (Stamoclean CAT, optional) A sample flow of to. m /h is permanently conveyed through the backwash filter by means of a sampling pump or compressed air or rinse water. The filtrate passes through the wedge wire sieve and is then transported to the measuring device. Clogging is minimised by the flow at the wedge wire sieve. Automatic backwashing results in a filter operating time of several weeks. The automatic backwashing and a small compressor or compressed air resp. rinse water supply guarantee low-maintenance and low-energy operation. Customer specific solution Before analysis, the sample has to be conditioned and to be transported to an external or to the delivered collecting vessel.
