Title: Liquids, esp waste waters, treated with reagents - at dose rates automatically regulated to correct changing conditions of continuous flow
IPC: C02F3/00
Filed: 1974-12-11
Abstract: A process and a plant installation for the continuous treatment of a liquid, partic. waste waters, is claimed, of the type in which a treatemnt reagent is injected into the liquid at a rate related to the condition of the liquid after treatment as measured by detector elements downstream of the reagent injection. A signal from the dector elements is used to regulate injector pump speed to increase or decrease the reagent dose rate as required, holding the pump speed constant when the treatment is satisfactory. Several different reagents can be injected at independently controlled dose rates, any two which neutralise each other being on mutually excluding actuating circuits. If the detectors reveal insufficient treatment at maximum injection of corrective reagent, the treatment liquid is pref. diverted automatically from the plant discharge line and recycled for further treatment. Automatic, continuous treatment of liquids, partic. industrial waste waters of e.g. unacceptable pH valve, recommend for treating effluent from paper mills, sugar refineries, chemical factories etc. Corrective dosing is automatically adjusted, almost instantly, as treated liq. shows any need for it, and insufficiently-treated outflow can be held back for further treatment.

Filed: 1975-04-18
Abstract: Device for measuring the number of units of pasteurisation or sterilisation received by a prod. e.g. in bottles in pre-determined time (T), has a thermometric pick-up located in the pasteuriser. From the electrical signal emitted by the pick-up, the numerical value of the speed of biological destruction (VDB) is calculated from the relationship VDB=10(-60)/7 where O = measured temp. Means are also provided for integrating the numerical value of (VDB) reckoned in units of pastuerization over the time (T). Novel feature consists in the location not only of the thermometric pick-up, but also the means for calculating and integration, near the prod. to be pasturised. Additionally the device is pref. integrated with a source of electrical energy and with a unit for displaying the number of pasteurising units counted, as well as with the thermometric pick-up. The device then forms a single block of low wt. and size, easily introduced or removed from the pasteuriser, and thus permits subsequently a direct reading of the number of pasteurising units received by the prod. Compared with existing systems, the new device comprises only simple, reliable and low cost electrical or electronic circuits, and allows the number of units of pasteurisation to be obtd. by direct reading without calculation and long, not very precise graphical methods.
