First, an overview
"Filtering" is the technical aspects of today's water treatment indispensable. ZW-F-type steel valve filter to create a new trend of domestic filtering technology. Thanks to hydraulic action from the water filter, water, backwash and sewage, etc., to achieve automatic, no special operation and management. As a result, it will completely replace the various types of filtration equipment produced by our decades applicable to water treatment, has a high water, electricity, section artificial, small footprint, sewage, etc.
Second, the principle
The raw water through the inlet into the filter through the filter layer top-down filtering, enter the deposit tank through the outlet pipe is full. Filter layer interception constantly suspended solids, resulting in increased resistance, and to promote the water level rising within the siphon, siphon assisted when the water level reaches the possession of the mouth, the water falling from the tube and air through the exhaust pipe in order to take siphon drop, when the vacuum reaches a certain value, will occur siphon effect when the water tank bottom-pass filter layer on the filter backwash. When the rinse water tank below the surface down to siphon damage and Tube, air enters the siphon, undermine the siphon effect, filter backwash to the end, the filter re-start.
Third, the technical performance
ZW-F series steel valve filter is a non-electronically controlled filtration devices, thanks to the pre-filtered water, gravity pressure and mechanical principles to achieve the automatic working. In vitro with no backwash water pump or water tower, water, water backwash and sewage, etc. do not need to set the operation of the valve and the corresponding electronic control facilities, thus saving pumping station civil engineering and electrical control instrumentation and equipment, no special operation management , low running costs.
1, raw water conservation, water production, water use ≥ 97? (See the National Water Supply and Sewerage Standards and Technology Commission test data).
2, no backwash facilities, and the working head (0.06MPa) so it is other than domestic filter to save power consumption of 20? Above.
3, simple structure, without any supporting facilities, saving pipes and civil foundation, small size, both indoor and outdoor settings, no special plant requirements, thus saving the investment in infrastructure, support facilities and installation costs.
4, the main components of the national standard body material is carbon steel working parts of stainless steel and copper pieces.
5, water quality 0.5-10NTU between the user can be arbitrarily adjust.
Fourth, the scope of
BZY-Ⅱ series steel valveless filters, mainly for the removal of particulate impurities suspended solids, solids and adsorption precipitation of filter can be formed to provide a variety of different uses of industrial water and domestic water.
1 for urban, rural, mining enterprises and other places the system? Of tap water filtration devices.
2, next to the circulating water filter device used in petroleum, chemical, metallurgy, electric power, textile, medicine, light industry, and mechanism of the production process.
3, the process of device used in luxury hotels, villas, hotels, shopping centers and other water features and swimming pool.
4, pretreatment unit for high purity water for boiler demineralized water and power industry.
For food, industrial and beverage industry to water treatment devices.
6, for the wastewater treatment process in the waterway, and for reuse and purification and filtration devices.
