1. Theory

The basic principle is almost as same as MVR concentrator. It may be distinguished in terms of the fact that the latent heat of evaporation energy is generated from the concentrator itself and it may be MVR type if it uses high pressure compressor or TVR if using steam ejector.
The system is a TVR concentrator in which high pressure steam is supplied to ejector and the vapor evaporated from the concentrator is inhaled into ejector to reuse it as the heat source of evaporation

2. Feature and Use

	It is suitable for a system to concentrate a material of which boiling point is high as it contains substances with high concentration and high boiling point.
	It does not need high power and may process large volume.
	It has high energy saving effect as it generates latent heat and evaporate circulating material by using evaporated steam.
	It is suitable for high concentrated wastewater that may possibly generate scale
