Diaphragm filter / tangential - Krauss-Maffei DCF
Dynamic membrane filtration
In traditional crossflow filtration, the development of a clogging layer on the surface of the filter membranes is prevented by pumping the feed. When handling sensitive or highly viscous products, this method is not efficient or not even feasible. In this case, traditional, circulating crossflow filtration technologies would not be able to concentrate liquids to a highly viscous sludge.
As dynamic crossflow filtration (DCF) is able to concentrate the retentate to a sludgy consistency, the efficiency of the separation process and yield of the valuable compound are higher than from any other crossflow technology.

Membrane ultra-filtration unit
Ultra-filtration plants can be constructed by employing hollow fiber membranes or spiral wound membranes.
They work with a pressure of about 1-10 bar and they are suitable to separate big molecules present in water, but not only that.

Membrane ultra-filtration unit
Ultra-filtration plants can be constructed by employing hollow fiber membranes or spiral wound membranes.
They work with a pressure of about 1-10 bar and they are suitable to separate big molecules present in water, but not only that.
Ultra-filtration process:
separate oils, bacteria, macromolecules like proteins for example.
most of surface-actives will let go through, along with inorganic acids and alcaline compound
pores dimension is about 0.005 – 0.1 micron; 1KD – 500 KD
Permeate coming from an ultrafiltration system is a limpid solution completely free of suspended solids.
In the field of ultra-filtration does exist a great variety of membranes along with the possibility to construct single or double passage systems, with recycle or not, etc. This means that there is a wide range of opportunities that will suit the client's requests.
Also working pressure can be modified in function of the client needs and of the kind of solution to be treated.
In civil application, ultra-filtration system is employed to reduce the presence of micro-bacteria.

Membrane micro-filtration unit for wastewater - 10 - 630 m³/h
Micro-filtration plants can be constructed by using hollow fiber membranes or spiral wound membranes. In case of special aplications it is possible to use ceramic membranes.
These plants work with low pressure (0.7 - 7 bar) and they are employed for the removal of suspended solids and molecules with a strong molecular weight.
The solution to be treated will be sent to the membrane surface; it will go through the membrane itself and at the same time the suspended solids will be stopped from the membrane surface and later they will be removed by the same flow of the raw solution. In this way the membrane surface will remain clean. The solution that is obtained after the removal of the suspended solids is called "permeate", and the solution which is the result of the removed solids is called "concentrate".
Micro-filtration process:
separate suspended solids from the aqueous solution
permit the passage through the membranes of all suspended solids
the width of membrane pores is 0.1 to 3 micron.
The production capacity of our plants goes from 10 to 630 mc/h.
