UF System (Ulta Filtration)

We design Ultra Filtration plants for various applications like RO pre- treatment, drinking water, ETP, STP as per customised requirements.

Ultra Filter VS. Conventional Filter:

Ultra Filtration like Reverse Osmosis is a cross-flow separation process. Here, the liquid stream to be treated (feed) flows tangentially along the membrane surface, thereby producing two streams. The stream of liquid that comes through the membrane is called permeate. The type and amount of species left in the permeate will depend on the characteristics of the membrane, the operating conditions, and the quality of feed. The other liquid stream is called concentrate and gets progressively concentrated in those species removed by the membrane. In cross-flow separation therefore, the membrane itself does not act as a collector of ions, molecules or colloids but merely acts as a barrier to these species.
Conventional filters such as media filters or cartridge filters on the other hand only remove suspended solids by trapping them in the pores of the filter-media. These filters therefore act as depositories of suspended solids and have to be cleaned or replaced frequently. Conventional filters are used upstream from the membrane system to remove relatively large suspended solids and to let the membrane do the job of removing fine particles and dissolved solids. In ultra filtration for many applications no pre-filters are used and ultra filtration modules do concentration of all the suspended and emulsified materials.

What is Ultra Filtration?

Ultra filtration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Ultra Filtration removes high molecular weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular weight organics and ions such as sodium, calcium, magnesium chloride and sulfate are not removed. Because only high-molecular weight species are removed, the osmotic pressure differential across the membrane surface is negligible. Low applied pressures are therefore sufficient to achieve high flux rates from an ultrafiltration membrane. Flux of a membrane is defined as the amount of permeate produced per unit area of membrane surface per unit time. Generally flux is expressed as gallons per square foot per day (GFD) or as cubic meters per square meter per day. Ultra Filtration membranes can have extremely high fluxes but in most practical applications the flux varies between 50 and 200 GFD at an operating pressure of about 50 psig, in contrast reverse osmosis membranes only produce between 10 to 30 GFD at 200 to 400 psig.

Process for UF System :

UF or Ulta Filtration is a seperation process to remove high molecular weight substances, colloidal materails, organic and inorganic polymeric molecules

FACTORS AFFECTING THE PERFORMANCE OF ULTRA FILTRATION:

There are several factors that can affect the performance of an ultra filtration system. A brief discussion is given below. Flow Across the Membrane surface : The permeate rate increases with the flow velocity of the liquid across the membrane surface. Flow velocity is especially critical for liquids containing emulsions or suspensions. Higher flow also means higher energy consumption and larger capacity pumps. Increasing the flow velocity also reduces the fouling of the membrane surface. Generally an optimum flow velocity is arrived at by a compromise between the pump horsepower and increase in permeate rate. Operating Pressure : Permeate rate is directly proportional to the applied pressure across the membrane surface. However, due to increased fouling and compaction the operating pressures rarely exceed 100 psig and are generally around 50 psig. In some of the capillary-type ultra filtration membrane modules, the operating pressures are even lower due to the physical strength limitation imposed by the membrane module. Operating Temperature : Permeate rates increases with the increasing temperature. However, temperature generally is not a controlled variable. It is important to know the effect of temperature on membrane flux in order to distinguish between a drop in permeate due to a drop in temperature and the effect of other parameters.

FAQs

RO Water Maker is a purifier system that uses the principle of reverse osmosis to remove 95-99% of all the mineral and chemical contaminants from raw tap water. R.O. gives you the quality of water.

The membrane consists of several thin layers or sheets of film that are bonded together and rolled in a spiral configuration around a plastic tube. (This is also known as a thin film composite or TFC membrane) The material of the membrane is semi-permeable with .0001 micron pores. It allows water molecules pass through while acting as a barrier to dissolved solids (i.e.: mineral chemical contaminants). When the feed water stream passes across the surface of the membrane, the molecules penetrate the membrane surface, working their way around the spiral and collecting in the center tube. The remaining contaminants are concentrated and washed from the surface of the membrane down the drain.

“One indication is a gradual reduction is water production caused by a layering of minerals and salts on the membrane surface. Another is gradual deterioration in the quality of water being produced. You my notice a different taste or whiter scrum on the inside of a pan of water you are boiling. This might mean the R.O. membrane is disintegrating and requires replacement. Generally it should change after 3-3.5 year from installation”
It is depended on Case to case. Generally Power consumpation require to run all the pumps.
It is deplended on RO feed water quality and design.
“Micron Cartridge Filter and RO Antiscalent chemical are consumable material. Micron Cartridge Filter change every three month and Antisclant yearly uses for 1000 LPH RO Plant @ 50 Kg base on 8 hr. working. “
It is use in utility persose flusing or Gardening. Aslo he put reject water RO plant for this reject water.
Depended on client requirement. We should supply both type manual and automazation plant.
Reverse osmosis systems reject particles down to the size of .0001 microns. A good reverse osmosis system will reject 95%-99% of most feed water contaminants. Industrial reverse osmosis systems typically recover anywhere from 50% to 75% of filtered feed water. So for every 100 gallons filtered, about 50-75 gallons is recovered as product water.
Because they produce great-tasting, very pure water at a reasonable price when compared to buying bottled water, and in a trouble-free, fully automatic format to boot. Committed water drinkers know, not all water tastes the same.
