The compact SCRUFILTER® units can be used in many applications of micro-filtration in order to reduce fine suspended solids from water down to 20 microns. The reduction of suspended solids is accompanied by a reduction in COD, BOD, phosphorus, nitrates and other substances. In the case of further treatment with UV for disinfection it is important to reduce the turbidity caused by suspended solids.
Standard filters are produced with supports in ABS and filter cloths in polyester. These can also be produced completely in stainless steel.
The filter cloth is selected according to the requirements which can be 20 - 30 - 40 - 60 - 80 or 100 microns. On special request different filter sizes can be produced.
Typical applications:
- waste water treatment plants (improvement of discharge),
- water recovery (food industry, textile, paper mill, etc.),
- beverage production plants,
- fish-breeding farms,
- filtration of surface water (river, lake, etc) and well water.
- High capacity
- Special civil works are not required,
- Level sensors for washing system are not present.
- Emergency overflow system.
- Economical exchange of the filter cloths.
- Simple and quick substitution of the filter frames without the necessity to remove the drum from the housing.
Fundamental Parameters:
- Capacity required in m3/h (or l/s if flow is not continuous).
- Quantity of suspended solids in inlet
- Requirements of filtered water
- Type of application
The above data is required to enable correct choice of the type of filter necessary, as this determines the choice of filtering cloth and the surface area required.
A fine cloth can achieve a better filtrate quality however having a lower permeability of the cloth will result in a lower filtration capacity.
In the majority of applications for tertiary treatment, cloths of 40 microns are used to achieve a reduction of 70-80% of the suspended solids. This obviously depends on the inlet quality.
