OUR FILTER
The NOVHIDRO disk filter has a wide range of work from 5μm to 500μm, giving the possibility of working in several applications within the filtering world. It also has the possibility of performing automatic backwashing thanks to our patented backwash system.
A complete filter.
CONNECTIONS
The filter consists mainly of two chambers, one of unfiltered water (whose connections are painted brown) and one of filtered water (whose connections are painted blue). The equipment has two main entrances to the unfiltered water chamber, these two connections are Standard 2 “and 3” used for the unfiltered water inlet.
Additionally, there are two pre-closed and threaded ports ¾”and ¼” used in special applications. The filtered water chamber has a 3″ grooved main connection that is used mainly as a filter outlet, and a ¼” socket whose main use is hydropneumatic cleaning and which is initially closed and unthreaded unless requested.
The NOVHIDRO Automatic Filters incorporate unprecedented functionality, simplicity and versatility in their design which allow to reduce time of installation and maintenance and replacement materials in a very considerable way and also all these tasks can be performed quickly and safely by any employee.
- Same body for 2’’ and 3’’.
• WATFLOW SYSTEM incorporated as standard.
• Adjustable hydro-cyclone effect.
• Conical upper body.
• Does not incorporate hydraulic system.
• Easy opening and removal of the cartridge.
• Manometer intakes included.
• Minimum body thickness of 10 mm.
• Micron rating from 5 to 500 micrometers.
• Considerable reduction of used space.
The NOVHIDRO Automatic Filters have an innovative and intelligent design, which gives them physical qualities capable of solving all the previous problems of this type of filters, which were being displaced by complex automatic mesh filtration equipment, sand filters and combinations of both systems.
FILTER TYPES
• Automatic filter.
It is identified by the blue sticker, this filter is capable of working with high pressures PN16 and needs a minimum pressure to perform the backwashing of 2.5 bar. The filtering surface is 5,050 cm².
• Low pressure cleaning.
This filter is identified by the green sticker, it is prepared to work at a lower pressure with a minimum consumption of energy. The minimum pressure to perform an effective backwash is 1 bar and the filtering surface is 5,050 cm².
• Manual filter.
This filter is identified by the red sticker, consists of a filter where the disks are fixed. You must open top cover to clean. Filtering surface is 3.920 cm².
• Filter for sea waters.
This filter is identified by the SW sticker. It is an automatic filter where all the materials used are prepared to be in contact with sea water.
WATFLOW SYSTEM
In case of low flow we can regulate it with the patented WATFLOW SYSTEM, which allows you to progressively graduate the inlet flow to the filter, by converting and adjusting the radial entrance of the water in tangential entry.
In addition, the higher the flow rate and the turbidity of the raw water, the more we will use this system to increase the centrifugal velocity of the water at the filter inlet and obtain the desired result regardless of the flow rate and the type of water.
The water inside the filter, due to the depression formed inside the cartridge, passes through the disks, which retain the particles in suspension and perform the filtering function.
Studies made by our R & D department contrasted by our sales and marketing team conclude that the most important factors when purchasing an automatic filtration system are:
- Filtration efficiency.
- Energy and water savings.
- Low maintenance costs.
Given the current demands on quality and standards in hydraulic complexes, based on previous projects, new technologies need to adopt systems which should address and solve all the issues in conventional filtration systems. We do this.
We now incorporate our revolutionary filtration system, patented “Watflow System”, in all our automatic filters.
Watflow system has among its spectacular qualities:
- Reaching degrees of filtering to 5 microns.
- Running the backwash as low as 1 bar.
- Reducing equipment size by making tower configurations.
- Controlling centrifugal water speed inside the filter.
- Avoid frequent manual cleaning with acids or other chemicals.
These, and many other qualities, make this system an essential element in filtration techniques with any type of water or particles.
Conventional filters use different mechanisms to produce the centrifugal acceleration of the water in the filter input, and thereby cause the hydro-cyclone effect, directly proportional to the water flow at the entrance.
Novhidro Automatic Filters incorporate the patented WATFLOW SYSTEM, which allows you to progressively graduate the inlet flow to the filter, guaranteeing at all times the hydro-cyclone effect independently of the flow. Besides which system also performs an effective dispersion of the particles.
THE SYSTEM CHANGES DIRECTLY FROM RADIAL TO TANGENCIAL WATER INLET. THROUGH MOVEMENT, WITHOUT TOOLS OR ANY OTHER EXTERNAL DEVICES, AVOIDING MAINTENANCE AND REPAIRS. IT ALSO ENSURES A MINIMAL LOSS OF CHARGE AND A MAXIMUN ENERGY AND WATER SAVING.
