Flood Water

The Ultra Purification makes Dirty (Flood-River) Water Clean Drinkable.

Ultra Filtration (U F) removes viruses as well as Bacteria from Dirty Surface water that may have come from rivers, lakes, rainwater collection barrels or puddles.

By using the Portable Purification unit, the risk of contracting gastrointestinal illnesses from Dirty Water is Reduced Drastically.

The Ultra Purification Products can be quickly and easily distributed during Natural Disasters.

The primary advantages of low-pressure Ultra Filtration Membrane Processes compared with conventional clarification and disinfection (Post Darrion Chlorine Dioxide) processes are:

• No need for chemicals (coagulants, flocculates, disinfectants, pH adjustment);

• Size-exclusion filtration as opposed to media depth filtration;

• Good and constant quality of the treated water in terms of particle and microbial removal.

Waterborne diseases continue to pose great risk to millions of people affected by the devastating floods in Pakistan, the United Nations warned today, a day after Secretary-General Ban Ki-moon, on a visit to the country, described the “heart-wrenching” suffering he witnessed among flood survivors.

The UN World Health Organization (WHO) said that in Khyber Pakhtunkhwa, one of the hardest-hit provinces, acute diarrhea is the leading cause of illness and accounted for nearly one in five patient visits since the floods began. The problem has also been reported in Baluchistan, Punjab and Sindh, the agency reported.

The UN Children’s Fund (UNICEF) estimated that as many as 3.5 million children in affected areas may now be at risk of diseases carried through contaminated water and insects. UNICEF plans to provide clean water to 6 million people.

“The lack of clean water and the unavailability of medication, in the aftermath of these floods, is a deadly combination. When added to the poor living conditions and the lack of food, which contribute to vulnerability, the picture is gruesome,” said Guido Sabatinelli, WHO’s representative in Pakistan.

Acute respiratory tract infections and skin diseases are the other health problems among those affected, according to WHO. Malaria could also pose a major threat as mosquitoes breed in the stagnant flood water.

Membrane filtration is classified as more advance & finer stage within filtration spectrum.

General structure of a Membrane Filter is a bundled form of thousands hollow fiber membrane capillary and encased within certain material of casing.

These membrane capillaries are low pressure driven element in water filtration, as low as 100 kPa (recommended operation pressure at 250kPa).

Membrane Filtration can filter suspended solids down to size 0.01 micron.

This is achieved by having the membrane capillary with pore sizes of 0.01 micron to separate & filter all contaminants effectively.

Therefore, Membrane is also an effective barrier against most waterborne micro-organisms that can even remove

Bundle of membrane capillaries bacteria & viruses which are ranging from 0.025-0.075 microns. This is laboratory proven.

Ultra-Filtration Membrane Water Filter Product Features

How Ultra-Filtration Membrane Water Filter can benefits the customers.

Membrane-Filtration is a lower pressure filtration technology used to remove suspended solids, sediments, rust, mud and other impurities from water.

The membrane used has pore sizes in the range of 0.01 to 0.1 microns, which will remove all suspended contaminants effectively.

Membrane is also an effective barrier against most waterborne micro-organisms that can even remove bacteria & viruses such as polio and rotavirus, which are a group of infectious agents ranging from 25 nanometers to 75 nanometers (0.025-0.075 microns) in diameter.

How does Ultra Filtration Membrane Water Filter work?

Ultra Filtration is designed with Outside-In flow configuration (contaminants are trapped outside of membrane’s capillary and clean water is zipped into it the inside surface of the capillary membrane remains completely clean during the whole filtration process.

Filtration Mode:

Contaminated water supply will enter to the membrane filter inlet and flow in one direction only.

Water will be diverted to each individual capillary and passes through outside the membrane capillary

Contaminants are trapped outside the capillary whilst pure water is zipped into it and released via the filter outlet.

Flushing (Forward) Mode:

During the filtration operation, the natural force of one direction water flow makes all the contaminants concentrate at filter’s the other end.

However, a normally closed control valve at Flushing port forward flushing process.

When this valve is opened, force of water flow flushes out the trapped & concentrated contaminants easily.

This self-cleansing system prevents clogging of membranes to ensure that the filtered water is always in it purest form.

What is Ultra Filtration?

Ultrafiltration is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, ultrafiltration will remove 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 meters per day.

Ultrafiltration 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.

Ultrafiltration, like reverse osmosis, is a cross-flow separation process. Here 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 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 these 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 ultrafiltration, for many applications, no prefilters are used and ultrafiltration modules concentrate all of the suspended and emulsified materials.

Ultrafiltration will find an increasing application in the production of high purity water. The basic principles outlined here should help in the understanding and use of this technology.
