2 Function and system design Measuring principle After sample conditioning, the analyzer 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 absorption intensity 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 C0-CA0XXx xx-00.eps Photometric determination Interferences Complexometric method for total hardness determination By adding MgEDTA to the sample, calcium is equivalently replaced by magnesium. At ph 0 calcium, magnesium and eriochrome black T form a ruby dye. The absorption is determined at a wavelength of nm (HA-A) resp. 880 nm (HA-B). The absorption intensity is proportional to the total hardness in the sample. The reference wavelength is 0 nm (HA-A) resp. 0 nm (HA-B).

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 a pressure pipe. The filtrate passes through the wedge wire sieve and is then transported to the measuring device. Clogging is minimised by the tangential flow of the wedge wire sieve. Automatic backwashing results in a filter operating time of several weeks. The automatic backwashing and a small compressor 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.
