　　Dalian pure water treatment equipment

　　Pure water equipment:

　　Producing drinking pure water device is consisted of pretreatment, reverse osmosis system and fine treatment and so on, which adopts unit combination structure, the purpose is to reduce the occupying area, make the transportation and field debugging more convenient, which also has the advantages of small working area, fast installation, beautiful appearance, simple operation and maintenance etc. The equipment is made from 304 stainless steel, pipeline low pressure device is made from ABS engineering plastic, high pressure device is made from high quality stainless steel, the main parts(membrane, pump, meter and so on) are provided by foreign famous professional manufacturer, the whole machine performance can reach the same level to the foreign countries!

　　Functions of this equipment: automatic and manual rinse of reverse osmosis membrane, when the pure water level is high, the equipment will stop automatically, when the pure water level is low, the equipment will start again, water shortage protection of multi-stage pump, protection of no-voltage, voltage shortage, overcurrent, short circuit, phase-break, electricity leakage.

　　Technology features:

　　According to the water quality for users, and the water quality of source water, the pure water equipments are full ion exchange system, reverse osmosis +mixed system, ultrafiltration+reverse osmosis +mixed bed system, ultrafiltration +reverse osmosis +EDI full membrane system and so on.

　　Ultrafiltration +reverse osmosis +mixed bed system: pretreatment adopts ultrafiltration, which can guarantee the SDI of reverse osmosis feedwater, then prolong service life of reverse osmosis membrane, this technology is suitable for source water of slight pollution or poor water quality.

　　1. Full ion exchange system, which is suitable for source water with low-content salt and frequent acid-base regeneration, the resistivity of output water quality is 0.5~15MΩ/cm,

　　Reverse osmosis +mixed bed system: the construction cost of pure water system is moderate, compared with full ion exchange system, this system has the longer regeneration cycle.

　　The dosage of acid-base is small, the cost of water preparation is low, the resistivity of output water quality is 5.0~ 18.2MΩ/cm.

　　●output water quality: the resistivity is 0.5~18.2MΩ/cm.

　　●the key equipment of system:reverse osmosis membrane,EDI module,pneumatic valve, which are the import or joint venture products, so that the reliability of system has been improved.

　　Treatment technology of pure water equipment:

　　Raw water tank→raw water pump→mechanism filter→active carbon adsorber→water softener→precision filter→first-stage high-pressure pump→first-stage reverse osmosis device→medium water tank→second-stage high-pressure pump→second-stage reverse osmosis device→ozonizer→pure water tank→water point
