Concentration

Evaporation/concentration

There are various methods for concentrating solutions. Such concentration methods are used individually according to the concentrations, components, and application purposes of solutions or they are used in combination. A method using ion-exchange resin, method using a nano-filter or reverse osmosis membrane, method using an electrodialytic membrane, and method using an evaporator are used in ascending order of concentration.
Various types of concentrators were also designed according to use application.
Such concentrators are classified into jacket type, calandria type, flash type, rising-film type, falling-film type, etc. according to the evaporation methods. Also, there are plate type, vertical tube type, horizontal tube type, etc. according to the shapes of the heating component, and further, an ejector type, heat pump (blower) type, multi-effect evaporator type, multi-stage flash type, etc. according to the energy-saving methods.
We design and manufacture systems that can be operated more efficiently and stably according to the liquid properties and purposes. We mainly adopt a rising-film type, falling-film type, and flash type.
To support energy saving, we mainly adopt an ejector type, heat pump type, and multiple-effect evaporator type.
