|Note: Filters of parameters not included in series of types we produce according to individual arrangements. For the given parameters the tolerance shall be taken consistent with the existing rules.|
Vertical pressure vessels FCP B, C, D are one of basic devices of technological system of water treating. After filling with properly selected filter bed and collaborating with hydro-pneumatic mixers and other technological devices they are mainly provided for removing iron and manganese compounds, turbidity, etc. from water.
In standard works all pressure filter elements (mantle, dished head, manholes, connectors, etc.) are made of low-alloyed certified steels. Maximum pressure PS=6bar and maximum temperature TS=50°C cannot be exceeded while exploiting the filter.
Filter is protected against to corrosion by painting: internally with polyester resins with PZH certification for contact with drinking water, externally with universal temporal protective paint. Manufacturer allows using other internal varnish sets (e.g. epoxy resins) and executions with external surface painting (e.g. set of polyurethane paints) – for client's special wishes.
Manufacturer can also offer devices with other anticorrosion protections e.g. by:
- hot galvanizing, two-sided (for diameters not bigger than DN 1800 mm)
- spray galvanizing, one or two-sided (for bigger diameters)
- ebonit lining (rubbering)
We also offer pressure filters made of austenitic steel.
Filters of diameters bigger than DN 2000 are supported on 4 bearings. The angular location of side-connectors in work C or D (draw.1) is connected with the supportings.
Filter in work B, C, D has plate filtration system, made in form of flat inner bottom, in which filtration drain (nozzles) are screwed in. In standard we use nozzles made of plastics PP with the filtration gap s=0,5 mm or s=0,2 mm wide. Filter in work B, C, D is equipped in additional manhole M3 which allows the internal revision under the filtering plate.
The manufacturer allows any constructional changes of a filter in the range of connectors' diameters and placing and the height of the cylindrical (filling) part
1. The manufacturer allows adaption of the filter construction to the requirements of Technological Design of the Object.
2. Difference in pressure before and after the filter bed can not exceed the value P=0,5 bar (filter rinsing).
1. Filters FCP are subjected to the instruction 97/23/WE (PED). In accordance with it and its guidelines they are included to devices produced consistent with engineering practice. In particular cases filters are given the CE sign.
2. For our filters we have the PZH certificate which allows contact with drinking water.
