Second, the installation requirements:
Winter indoor ambient temperature: not less than 10 ºC Power: 380v 50Hz
Area: 150-300m2 Raw water flow: ≥3m3 / h
Third, the system advantages:
1, the device is running to achieve automatic membrane flushing function, the interval of 1-6 hours adjustable.
2, low-voltage protection system, when the water pressure is insufficient or passive water when the device automatically shut down to protect the high-pressure pump and equipment safety.
3, the device has a manual, automatic control function, the device does not need to operate automatically when the operation.
4, the equipment used stainless steel frame structure, to achieve no health dead ends, equipment, no corrosion, the use of 10-20 years is still as new.
5, the equipment is equipped with online water quality detector, at any time to observe the water quality.
Fourth, the pure water process and description:
1, pure water system process:
Water source - raw water tank - raw water pump - quartz sand filter - activated carbon filter - scale inhibitor dosing system - precision filter - high pressure pump - pure water tank
2, pure water equipment process description
First level pretreatment system
The main purpose of the use of quartz sand multi-media filter, the main purpose is to remove the water contains the sediment, manganese, rust, colloidal substances, mechanical impurities, suspended solids and other particles in more than 20UM harmful substances.
Second level pretreatment system
The use of activated carbon filter, remove the water pigment, odor, a large number of biochemical organic matter, reduce the residual chlorine in water and pesticide pollution and other harmful substances harmful to the human body.
Third level pretreatment system
Using the scale inhibitor for softening, the main removal of water hardness. Water hardness is mainly calcium (Ca2 +), magnesium (Mg2 +) ions, which effectively prevent the reverse osmosis membrane fouling.
Fourth level pretreatment system
The 5-micron pore size precision filter allows the water to be further purified to optimize the turbidity and chroma of the water. To ensure that the RO system water requirements.
Pure water equipment host system
Reverse osmosis technology for desalination, reverse osmosis membrane pore size of only 0.0001 microns, can remove harmful soluble solids and bacteria, viruses, etc., desalination rate of 90-99% or more, to produce in line with national standards of pure water, the host Part of the security filter, high pressure pump and reverse osmosis membrane, the security filter for the above fourth level pretreatment system, high pressure pump is one of the core equipment on the host for the reverse osmosis membrane components to provide sufficient pressure to overcome the penetration Pressure and running resistance to meet the device to achieve the rated water discharge.
Ozone sterilization system
Ozone has a strong oxidizing, there are four major functions: sterilization, oxidation, decolorization, in addition to taste, for water disinfection, the concentration of 4mg / l, 0.5-1 minutes to kill all bacteria, while ozone dissolved Water after the formation of oxygen-rich water, to ensure that the water of pure fresh, without losing the activity of water.
