Definitions

  • the invention relates to a water treatment plant according to the preamble of claim 1, a method for operating a water treatment plant according to the preamble of claim 6 and a computer program according to claim 8.
  • Such a known water treatment plant serves both for drinking and for process water treatment.
  • conventional methods for treating the water by means of e.g. Sand or activated carbon filters, as well as plants using membrane filters known.
  • membrane-based treatment plants are e.g. for bacteria an absolute, i. impenetrable barrier as long as the membrane is intact.
  • This safety as well as some other aspects allow a strong automation of the system, so that no operator must be present.
  • This allows the economical use of smaller, decentralized water treatment plants.
  • These systems are increasingly being conceived as standardized solutions which, by means of a modular design, can be adapted to requirements such as e.g. the required flow rate can be adjusted.
  • Dirt particles in the water treatment plants are deposited continuously and must be removed regularly, eg by backwashing.
  • a chemically assisted cleaning is required, typically with acids, bases or with oxida- active / chlorine-based substances.
  • a disadvantage of the standardized water treatment plants is considered that they are not optimally adapted to fluctuations such as the raw water composition due to, for example, heavy rains. This is due to the fact that due to the required process reliability, for example with regard to the cleaning intervals, fixed, periodic intervals are predetermined or these are coupled to a specific differential pressure at the membrane. Therefore, the operating costs are not optimized in the known systems at the expense of reliability.
  • the invention has the object of developing the known water treatment plant such that it adjusts its operating parameters of the current composition of water and thus enables optimized operation. This optimized operation leads in particular to a reduction of operating costs. Furthermore, the object is to provide a method for operating a water treatment plant and a dedicated computer program.
  • Fig. 1 is a schematic representation of a water treatment plant.
  • a water treatment plant 10 is shown.
  • the water treatment plant 10 has a filter element 11.
  • the filter element 11 is preferably designed as a membrane filter element, in particular as a hollow fiber membrane element with pores corresponding to ultrafiltration and microfiltration.
  • the filter element 1 1 is connected between a supply line 13 for the raw water and a discharge line 14 for the cleaned of the filter element 1 1 water.
  • a pump device 15 is arranged for the water, the power and thus flow rate can be regulated.
  • a controllable pumping device 15 it is also conceivable to regulate the volume flow via a throttle valve.
  • the pumping device 15 alternatively in the discharge line 14 and to suck the water through the filter element 11.
  • the filter element 1 1 is coupled to a cleaning or purging device 20.
  • a cleaning or purging device 20 can be connected to the filter element 11, which comprise, for example, separate containers or supply lines for cleaning or rinsing substances.
  • an outgoing from the filter element 11 discharge 21 is provided, can be removed via the residues or backwash.
  • the water treatment system 10 further comprises a control unit 25, which also serves in particular to control the cleaning or rinsing device 20.
  • the control unit 25 is coupled via a control line 26 to an operating unit 27, via which relevant data for operating data can be entered and / or operating parameters to be optimized, which are explained in greater detail later, can be selected.
  • the control unit 25 can furthermore be connected in a manner known per se via a data line or via the Internet to other relevant points.
  • control unit 25 and the one or more cleaning or purging devices 20 are connected to one another via a bidirectional data line 28. By means of a further control line 29, the control unit 25 controls the pumping device 15.
  • the water treatment plant 10 described so far is additionally equipped with a number of sensors.
  • the sensors comprise a differential pressure sensor 30, which is connected between the supply line 13 and the discharge line 14 of the filter element 11, and which is connected to the control unit 25 via a line 31.
  • a turbidity sensor 32 connected in the supply line 13 and a temperature sensor 33 are provided, which are connected to the control unit 25 via lines 34, 35.
  • a sensor 37 for detecting the power consumption of the pump device 15 is provided, which is coupled via a line 38 to the control unit 25.
  • the control of the water treatment plant 10 by means of the control device 25 is carried out in particular on the basis of the following operating parameters: the volume flow of the water, the interval between flushes by means of the cleaning or purging devices 20 and the purging duration and possibly the purging pressure. Furthermore, in the presence of chemical cleaning substances, the time interval between two cleanings, the cleaning time, the cleaning temperature, the cleaning time, medium concentration and the type of cleaning agent used. If additional auxiliaries, such as flocculants, are used, their added amount is coupled to the volume flow or the concentration of the impurity.
  • a computer program 40 is provided in the control unit 25, which adapts the operation of the water treatment system 10 adaptively, ie independently, to the composition or the quality of the raw water and automatically reacts to fluctuations in the water composition.
  • the control of the cleaning or rinsing device 20 (which, as already mentioned, works either with rinsing water or with additional chemical substances), and / or, for example, the flow rate at the pumping device 15 should be optimized such that in particular one Optimization of operating costs is achieved, ie they reach a minimum overall.
  • the operating costs represent an indirect operating parameter of the water treatment plant 10, which arise as a function of the individual (direct) operating parameters mentioned above.
  • the measured values of the operating parameters acquired via the various sensors are stored in the control unit 25 in a measured value memory 39 or used as input variables in an algorithm or a plurality of algorithms in the computer program 40.
  • the algorithm or the algorithms should independently develop their own operating strategies or vary the above-mentioned operating parameters in a window given as meaningful in order to achieve, depending on the water composition, in particular the minimum of operating costs.
  • These operating parameters and their relevant properties are predetermined by means of the operating unit 27 and may be varied or adapted so that the invention should not be limited to an optimization of the operating costs.
  • a minimum of operating costs for a certain amount of water for example, at a certain rinsing interval with a certain rinsing time in combination with a certain addition of chemical cleaning substances and a certain flow rate results. If the quality of the water changes, a new minimum of operating costs can result with a reduced flow rate, a longer cleaning interval, and at the same time a longer rinsing time and an increased addition of cleaning substances.
  • the operating parameters are then updated in accordance with the instantaneous composition of the water (taking into account the time profile of the water composition and the time profile of the operating parameters) in order to minimize overall operating costs.
  • the computer program 40 controls the cleaning or purging device 20 or the pumping device 15 as needed in the sense of minimizing the operating costs via the control device 25.
