摘要:
There is provided an efficient treatment method for boron-containing water capable of reducing an amount of use of medical agent and an amount of generation of sludge. A treatment method for boron-containing water of an embodiment includes a first process of concentrating boron-containing water to obtain boron-concentrated liquid. Further, the method includes a second process of making the boron-concentrated liquid to be brought into contact with a layered inorganic hydroxide, and making the layered inorganic hydroxide adsorb boron in the boron-concentrated liquid to remove boron.

A wastewater treatment method in an embodiment includes: mixing primary aggregates made of magnetic substances and a dispersion medium to make a suspension; and passing the suspension through a filter to allow the primary aggregates to remain on the filter and to form a secondary aggregate made of an aggregate of the primary aggregates. Further, the wastewater treatment method in the embodiment includes; passing wastewater through the secondary aggregate to remove suspended solids and oil in the wastewater; dispersing the secondary aggregate in a dispersion medium to decompose the secondary aggregate into the primary aggregates and to wash the primary aggregates; and collecting the primary aggregates with magnetic separation.
摘要:
A polymer composite is provided for a water treatment. The polymer composite with excellent workability is capable of adsorbing impurities in water, being rapidly separated from the water using magnetic forces. The polymer composite includes secondary aggregates. The secondary aggregates are formed of clumped particles, the particles being magnetic particles covered with a polymer. The polymer composite has porous structures suitable for adsorbing underwater impurities.
