    • The present invention, a water treatment method using a hydrate-purifying process comprises the following steps. Water containing impurities, and multiple guest gas are injected into a reactor; the water and multiple guest gas are reacted under a first condition, which produces gas hydrate; and the first condition changes into a second condition, which starts dissociation of gas hydrate from one of the multiple guest gas. The first condition satisfies a temperature and pressure that the all guest gas form gas hydrates. The second condition satisfies a temperature and pressure that one guest gas is dissociated from the mixed gas hydrates. The present invention can remove impurities including salt mixed with the gas hydrate by dissociating the multiple guest gas step by step, which comprises: making a reaction between the water and multiple guest gas which are injected into the reactor; producing the gas hydrate; and lowering the phase change pressure.

    • PURPOSE: A recovery method of SiC and/or Si solid particulates is provided to be able to separate and collect solid particulates with relatively large particle size from liquid containing SiC or Si solid particulates, and to collect all solid particulates by efficiently separate super fine solid particulates which have smaller particle size than the solid particulates from liquid. CONSTITUTION: A recovery method of SiC and/or Sic solid particulate comprises the following steps: a step of separating and collecting solid particulates of relatively large particle size among solid particulates from liquid containing SiC and/or Si solid particulates by the centrifuge and/or liquid cyclone, and discharging remaining liquid with solid particulates of relatively small particle size; and a step of collecting aggregates by adding an organic coagulant to the discharged liquid, and centrifuging or filtering the liquid containing aggregates formed by coherence of the solid particulates of relatively small particle size. The organic coagulant is a cationic organic coagulant described in chemical formula 1. In chemical formula 1, R1 is hydrogen or methyl group, R2 is alkyl group of 1-10 carbons, X is one halide selected from Cl, Br and F, a is the number of 0-10, b is the number of 1-10, m is the number of 3 and bigger.
