The invention provides a water processor for conditioning content of mineral substances of 
water based on purification. The content of the mineral substances of 
effluent water can be controlled by conditioning the angle of a valve which is connected in parallel with 
reverse osmosis, the conditioning method is simple, results is directly displayed by a display circuit, and the effect is intuitional. The water processor adopts brand-new 
process control technology, generates brand-new results which cannot be generated by the prior 
material technology, creates brand-new 
water quality which can hardly universally exist in the natural world, and creates and meets the brand-new usage classification and usage requirement, so that users can conveniently and personally participate in the technology to determine the 
water quality required by the users, such as 'best 
mouthfeel' water with water 
hardness of 30mg / L, 'most proper for people requirement' water with the water 
hardness of 170mg / L, or proper water for tea making, or 
skin beautifying water and other brand-new usages and requirements. The 
controllability of the process and flexible intelligence of 
computer program ensure the 
water quality to be more reasonable, and represent one of new development directions of water quality 
processing technology in the future.
