STF FMA-7000uv Self Cleaning Filter
The FMA 7000 STF filter is a mesh filter with electrically operated automatic disinfection treatment with ultraviolet lamps, specially designed for low leakage to filtration sizes disinfection treatment for low flows in municipal and industrial applications.
Adapting our designs to the new legislation, STF adjusts the Royal Decree of reuse of treated water 1620/2007, with a team that combines action with disinfection filtration in one unit, reducing installation space and increasing the simplicity system.
The washing machine performs automatically without interrupting the operation of filtration of the fluid, is also capable of disinfecting liquid without adding any chemicals to the water in the pursuit of minimizing the impact on the environment.
The filter FMA-7000-UV comprises a water inlet connection to treat, another output of treated water drainage third cleaning equipment. When water enters the interior of the chamber 1, (filtration) reduces its speed and will produce a retention of all particles as filter cake on the filtration mesh size selected.
Once the fluid has passed through the first stage, this is directed towards the top of the filter through a conduit inside the cartridge. At the end of the fluid conduit is a ultraviolet lamp interlaced capable of destroying bacteria and virus DNA emitting type C ultraviolet light at 254 nm.
The germicidal action starts when the fluid begins to process the output direction of the equipment, the fluid flows at a speed that is applied to the dose recommended for each application.
The team FMA-7000-UV is fully automatic, boasting two washing system for both filter mesh to sunlamps.
As dirt builds up on the filter mesh creates a pressure differential. When it reaches a preset differential pressure detected by pressure transducers analog, the computer initiates a wash cycle which consists in opening the drain valve and the rotation of a nozzle system with nylon bristles which suck dirt that has been retained in the filter mesh. Backwash cycles of the filter cloth can also be manually initiated or timed.
Ultraviolet lamps have an automatic cleaning of the quartz glass that protects the lamp, in order to maintain the effectiveness of the system during the lifetime of the lamps cleaning initiating the same time or when a sensor indicates a reduction in radiation.
In recent years the technology of ultraviolet disinfection has been implemented as an alternative to chemical disinfection is more respectful of the environment and less environmental impact on water courses. But not always implemented this system correctly, since for the correct operation of the system is required pretreatment of the water to reach the disinfection system in ideal conditions.
One of the problems that decrease disinfection performance is called "shadow effect" which occurs when the system water entering the UV disinfection containing a high concentration of suspended solids of a size sufficient to cause these Solid prevent the onset of radiation to try organic matter degradation. To avoid this effect is likely to have a filtration system in addition to disinfection.
The treatment team proposed STF combines the two treatments in one device, thus ensuring the proper operation of the disinfection system and further reducing the concentration of suspended solids in water reuse systems
Because of its configuration, the FMA-7000-UV is ideal for installation in sewage treatment plants, cooling systems and industrial systems, as well as ensuring quality parameters of water, reduces both economic costs of implementation, as maintenance, and significantly reduce the space required for installation.
