Abstract:
The present invention relates to an apparatus for separating solid materials using standing waves, which effectively removes solid materials contained in contaminated water and comprises: a tubular housing (100) with a flow path where contaminated water flows in through one side of the path and is discharged through the other side of the path, and the one side and the other side take open formation; an authorizing unit of standing waves (200) where standing waves are formed along the diameter direction of the housing (100) since the authorizing unit is arranged outside the housing to mutually face; and a filtering member (300) through which contaminated water flowing inside the housing (100) passes to filter solid materials as the filtering member is installed in the flow path of the housing (100) in the rear side of the authorizing unit of standing waves (200). The apparatus of the present invention enables effective control of intensity and frequency of standing waves and size adjustment of the medium of the filtering member according to the diameter characteristics of the solid materials included in contaminated water, thus increases the removal efficiency of the solid materials included in contaminated water.
Abstract:
The present invention relates to an apparatus arranged in one side of a settling chamber (1) for separating fine organic particles from supernatant stored in the settling chamber capable of enhancing the contaminant removal efficiency, comprising: a housing (100) having a certain internal space (110) with an opening form in the upper surface, connected to an inlet pipe (120) to which the supernatant liquid is introduced the at one side, and connected to an outlet pipe (13) from which the fine organic particle separated supernatant is leaked; an air bubbles (200) installed on the certain internal space (110) for generating bubbles; and an ultrasonic generator (300) arranged on the outer surface of the housing (100) to generate multi-frequency signals for refining the organic particles to be adsorbed on the bubbles. The configuration of the present invention enables removal of micro-pollutants from contaminated fresh water substances such as sewage treating water in low specific gravity. The apparatus of the present invention is Installed and integrated inside the settling chamber not requiring, so that additional land and facilities are not required as well as contaminant removal efficiency can be increased because contaminants to be removed and behavior characteristics such as surface activities of bubbles are reformed at the same time.
Abstract:
A gypsum material for reducing release of phosphorous from sediments of eutrophic lakes, which can reduce dissolution of sulfate according to the application of the gypsum material and can suppress the generation of methane at the same time by capping sediments in lakes using sand and gypsum granules prepared by adding ferric oxide(Fe2O3), and a method for preparing the gypsum material are provided. A method for reducing release of contaminants from a sediment(2) of an eutrophic lake comprises: capping a granule gypsum layer(4) with a predetermined thickness on the sediment of the eutrophic lake, prepared by granulating the mixture after mixing gypsum powder as an oxidizer with ferric oxide(Fe2O3). The method further comprises secondly capping a sand layer(6) with a predetermined thickness on the granule gypsum layer. The granule gypsum layer is prepared by mixing 100 weight parts of gypsum powder(CaSO4.2H2O) with 10 to 100 weight parts of ferric oxide(Fe2O3) for delaying the rate of release of sulfate ions from the gypsum powder, mixing 30 to 40 weight parts of water having room temperature with the mixture, kneading the mixture, drying the kneaded material at 100 to 105 deg.C for one hour, cutting the dried material to a predetermined size, granulating the cut material, and sintering the granulated gypsum at 550 deg.C.
