Title: Optronic visual range indicator
Inventor: WITTMER DETLEV DR
IPC: G01S17/931
Filed: 1993-08-04
Abstract: A visual range indicator (11) which is more cost effective than measurement of propagation time measures the intensity (i) of the reflection (20) of a volumetric element (30), provided with scattering particles (13), at the point of intersection of the emission direction of a radiation source (15) with the receiving characteristic of a receiver (22) at a distance (1), prescribed by the design, in front of the arrangement of radiation source (15) and receiver (22). Since the paths of emission and reflection and the transmitter power are constant, because of the two-fold damping path the reception intensity (i) drops with rising turbidity (cloudiness, opacity) of the atmosphere (air space 21) despite an increased scattering effect of the volumetric element (30) detected. The damping component of a polluted disc (12) upstream of the transmitting and receiving arrangement is eliminated by forming the mutual ratio of the intensities (i1, i2) of reflection of two volumetric elements (30.1, 30.2) in the evaluation circuit (28) which are mutually offset with respect to distance. <IMAGE>

Abstract: A process monitors and controls a biological aerobic water treatment process and plant by using the decomposition rate of the micro organisms as an indicator.An up-to-date set of microorganism substrate decomposition parameters is determined by means of a program (1). A set of parameters is generated using data gathered over a long period of time and processed by a program (II) to describe the average rate of micro organism substrate decomposition. Determn. of the microorganism decomposition rate is made which is characteristic of natural undisrupted decomposition by means of a program (III) using the parameters determn. and the values determn. in the present flow of effluent water w.r.t flow vol., carbon concn. and incoming nitrogen.The rates determined by programmes (I) and (III) are approximately the same provided that the process is undisrupted. If there are significant differences between (I) and (III) these differences are used as corrective inputs to the plant.The parameters monitored are oxygen concn., fluid inlet and outlet flows, carbon concn., nitrogen input, buffer levels, gas inputs, solid content, ammonia, nitrite, nitrate and pH.
