A process is disclosed for controlling the composition of a product from a device for sizing and sorting mineral raw materials, in particular sand and gravel, which must keep a predetermined finest sand concentration in the sand product quantity. For that purpose, an additional sizing separation of the sand product quantity into a sand fraction (mPr) and into a finest sand fraction (mFSS) to be discharged through the overflow is carried out in the chamber above the level (hFS) of the fluidised bed contained in the chamber. In order to set a predetermined finest sand concentration (C<Prsoll) in the sand product quantity, the level (hFS) of the fluidised bed is regulated in such a way that the proportion of finest sand (m<A) in the loaded amount of raw material can be divided by the fluidised bed into a finest sand proportion permissible as a function of the predetermined concentration (C<Prsoll) to be discharged into the sand product quantity (mPr) and into a finest sand proportion (mFSS) to be discharged through the overflow. | ||||||

244 | WATER CLARIFIER WITH FIRST FILTRATE ISOLATION, IMPROVED BACKWASHING AND IMPROVED BUBBLE GENERATION | EP93913923.4 | 1993-05-17 | EP0641292B1 | 1998-09-09 | KROFTA, Milos |
A two stage raw water clarifier with first stage flotation and second stage filtration divides at least the lower portion of a flotation tank into independent cells. A branched slotted conduit located in a filter medium in each cell collects clarified water. Valves control the flow of clarified water from each branched conduit either to a clarified water ring conduit or to a first filtrate/backwash ring conduit connected to a storage tank. The filter media is preferably a dual media, a layer of anthracite or activated carbon over a layer of sand. High cell walls and inclined baffles in each cell retain the filter media during backwashing. The baffles also slow the flotation process. A decompression valve for pressurized water with dissolved air has a very narrow annular slot in the flow path through the valve to create microscopic air bubbles of optimal size for the flotation. A movable member sets this annular slot at a proper value. A mechanical or pneumatic actuator moves the member periodically to open the slot and flush out trapped particles. | ||||||
245 | COMPACT CLARIFIER SYSTEM FOR MUNICIPAL WASTE WATER TREATMENT | EP94911642 | 1994-03-18 | EP0689521A4 | 1997-11-19 | KROFTA MILOS |
A compact water treatment plant has at least one vertical stack of dissolved air flotation (DAF) type clarifiers. Raw water is directed first to a single stage clarifier with a shallow tank. Its output is fed to an underlying two stage clarifier, preferably one with tall, mutually isolated cells, inclined baffles over a filtration medium in each cell, a cell-by-cell backwash capability, and an arrangement for isolating the first filtrate from the clarified water. Preferably, there are two such stacks in side-by-side array to provide a peak-load capacity, redundancy, and extreme compactness. Also preferably, clarified water from the single stage clarifier flows to the two stage clarifier via a bioreactor and an associated DAF clarifier. A source of aeration defines an upper, aerobic zone in the reactor where bacteria act on organic contaminants (COD's and BOD's). Strips of a deep pile, woven textile form a biocarrier. The strips oscillate in the tank. A portion of the bioliquor and sludge from the bioreactor-dedicated clarifier recirculate through a lower, anoxic zone of the bioreactor for denitrification. | ||||||

Water clarifying apparatus has a cylindrical tank where particulate contaminants suspended in raw water are separated using flotation techniques. A set of concentric mutually spaced, conical plates are positioned in the flotation tank. The plates rotate about the tank, preferably in unison with a (i) header that distributes equal quantities of raw water to each annular zone in the tank defined by the conical plates and (ii) a scoop for removing the contaminants which form a floated sludge layer. A screw conveyor is located in a discharge pipe of the floated sludge scoop. A infrared sludge detection array in a window in the side wall of the tank senses the sludge-water interface. Air dissolving tubes operating in parallel have common feeds and discharges coupled through three way valves operated to pressurize a closed volume of water with high pressure air in one tube while reloading and discharging the other tube. | ||||||

A gravity mineral recovery apparatus and process (10) uses stratification to separate the relatively heavier valuable particulates from the lighter tailings in ore (O). A housing (12) holds a process chamber (14) therein, the chamber (14) capable of oscillating within the housing (12). Ore (O) is gravity fed into the process chamber (14) and falls toward the bottom with the ore (O) channeled to the outer sidewall of the process chamber (14) by a deflector (46) that creates an annular passage within the chamber (14). The oscillation of the chamber (14) causes the heavier particulate to stratify into circumferentially disposed hoppers (62) while the tailings are discharged through a central chute (58) to a tailings hopper (96). The hoppers (62) have compound sloped sidewalls (64) and have a sensor (84) for opening a discharge valve (74) within the hopper (62) once a given concentration is achieved. A series of sensors (106, 108, 1 10, 1 12, 1 14) within the tailings hopper (96) control a tailings discharge valve (102) as well as an ore feed valve (94). Water (W) constantly flows through the system (10) yet does not participate in the actual transport of the particulates. | ||||||

A method for separating particles of different specific gravity from a sized ore feed, wherein the ore can be coal, metallic, non-metallic and mineral ores. The method particles from the ore are sieved to obtain size fractions of different particle size ranges, after which a load of particles of a size fraction are placed in a container and fluidized by passing a fluid flow through the load of particles. By lowering the flow velocity of the fluid through the load the particles are deposited in the container in one or more layers depending on the specific gravity of each of the particles, after which the deposited particles are separated in portions of different specific gravity. The portions represent different ore content of the particles in each portion on basis of which the theoretical yield of the ore can be determined. The invention provides an apparatus to carry out the method. | ||||||
