Ultrafiltration - Import export

A convenient and reliable technology of separation for treatments of surface water, conditioning and sterilization, civil and industrial sewage.

Ultrafiltration and microfiltration differ depending the pore size used. Ultrafiltration can filter out bacteria, viruses and other organisms. Both methods are also applied in the field of water recycling. They sperate undissolved and colloiddissolved solids.

Ultrafiltration extends the life of washwater, floor scrubber and vibratory/tumbling water. PRAB’s line of Ultrafiltration Systems are designed to separate organics, emulsified oils and suspended solids from process water, incoming water, wastewater and metalworking coolant reducing oily water volumes by as much as 98% without the use f chemical additives. For this reason, Ultrafiltration membrane technology is quickly becoming the fluid waste management process of choice over conventional industrial filtration methods. PRAB Water & Wastewater is a leader in fluid management, Ultrafiltration, wastewater reuse, process water reuse, and Reverse Osmosis pre-treatment with partnerships that span globally. Our Ultrafiltration Systems reduce the cost of wash water and detergents by as much as 75% when calculating the costs of replacement chemicals, heating and disposal. Effluent water can be discharged to sewer or reused.

Ultrafiltration of surface water For separation of dissolved substances, ultrafiltration is applied apart from conventional pre-filters (sand and gravel filters). So, all solids and even bacteria, viruses, germs and colloidal components (iron, orthosilicic acid) are retained.

Disposal of oil emulsions by ultrafiltration Increasing disposal costs and laws about oil disposal make a treatment of oily emulsions right necessary right where they come up. The main target of this treatment is the reduction of waste volume as much as possible. Ultrafiltration is one possibility to separate even stabile emulsions. Like chemical methods and flotation, ultrafiltration can not be used as stand-alone solution. Only by an effective pre-treatment and a pre-treatment of the oily concentrate, an optimized and economical emulsion disposal can be guaranteed. By the pre-treatment, coarse particles and free oil is separated; the pre-separation dewaters and concenctrates the flow, which comes as concentrate from the ultrafiltration. So, a maximum of dewatering and concentration of the oil can be reached. The emulsion is pumped through the membrane modules of the plant. On the membrane surface, oil is separated from the waste water. Waste water will pass the membrane and is colle

Ultrapure water has an extremely low conductivity since it has been totally desalinated. There are no ions (contamination) in ultrapure water because of the poor conductivity. Salts can be removed from water using a variety of methods. For this, Grünbeck uses our high-quality reverse osmosis installations, followed by a mixed-bed or electro-de-ionization process (EDI).

The Backwashing adjustment of the emphasis on the extraction side only works when used in pressure areas It is in accordance with the specifications of DIN EN 13443-1 and DIN 19628 and for installation in drinking water installations in accordance with DIN EN 806-2 . It protects the water pipes and the connected systems components against malfunctions and corrosion damage
