  • Solid-liquid separator
    Patent number: 8349177
    Abstract: A solid-liquid separator that separates raw water containing suspended solids into suspended solids (solid) and treated water (liquid) in easy and a short time is provided. A solid-liquid separator includes a separation tub, an inflow pipe configured to rotate raw water which flowed from the outlet of the inflow pipe in the separation tub, a froth discharge pipe configured to discharge the suspended solids surfaced in the separation tub and a treated water discharge pipe configured to discharge treated water by which the suspended solids were removed from raw water from the separation tub.
    Type: Grant

  • Heavy metal collection system
    Patent number: 8002980
    Abstract: A former (11) works, when supplied with wastewater containing heavy metals and hydrogen sulfide, to react heavy metals contained in wastewater with hydrogen sulfide to form sulfide salts, an acquirer (12) works, when supplied with sulfide salts and acid, to acquire hydrogen sulfide and heavy metal ions produced by reactions between sulfide salts and acid, a hydrogen sulfide supply line (13) supplies hydrogen sulfide acquired by the acquirer to the former, and a collection line (20) collects heavy metal ions.
