Rotary-pulse apparatus (RIA) is designed for processing liquids, pastes and slurries. In the purpose of CWS production it used for preliminary water activation which is pass to wet-milling device.

RIA can also be used as a standalone unit for processing liquids and slurries. Major functions of RIA are homogenization and activation (cavitation). The result of water cavitation and activation is reflected in water heating and increasing pH-level.
