What is Membrane Technology's place in water and
wastewater treatment?
Membrane Technology is a unique crossflow microfiltration
utilizing patented technology which differs from any other because of the material used as
its filtering element. The membrane material is extremely robust, providing very long
service, even when handling high concentrations of solids, including abrasives. The
filtering element is also collapsible, which aids in its cleaning. The Membrane Technology
filter can produce a filtrate so clean that even most bacteria have been removed. Even
while efficiently removing such finely divided particles as bacteria, it can economically
handle flows from a few gallons per hour to millions of gallons per day.The Membrane Technology system can be used to treat water and wastewater, or other
liquids, for the removal of contaminants that:
1) are solids, including bacteria;
2) can be converted into solids by precipitation; or
3) are dissolved, but can be adsorbed onto a solid adsorbent injected into the water.
This technology bridges the gap in available water and wastewater treatment equipment
between the sensitive ultra-filtration membranes and traditional filters like multi-media
or sand filters.
What can Membrane Technology do that traditional technology can't?
Traditional membrane materials are sensitive and easily damaged, so require frequent
replacement. Traditional solids separation processes, such as performed in clarifiers, are
frequently upset owing to the diversity of strengths and flows of waters they receive.
Traditional processes are inefficient at removing very finely divided solids.
The Membrane Technology system avoids these difficulties and makes it possible to:
Ÿ Produce better treated water quality.
Ÿ Perform traditional treatment processes more economically with fewer chemicals.
Ÿ Perform crystal growth processes enabling it to operate traditional treatment
processes much more quickly.
Ÿ Eliminate the problems associated with backwash water.
Ÿ Perform acid waste neutralization (AWN) recovery.
Ÿ Remove grinding fines (silicon, diamonds, aluminum oxide and fumed silica).
Ÿ Remove oil and grease without flocculants.
Ÿ Remove virtually all silica from RO feed and RO brines.
Ÿ Remove TOC to barely detectable levels.
Ÿ Reduce silt density indices to extremely low values for RO feedwater.
Sanitherm's Products In Action - Membrane Technology at Work
New
Membrane Bioreactor (MBR) Plant Installed in Pemberton, BC
From 2003 to July 2005, Sanitherm
has supplied over 31 submerged
Membrane Bioreactor (MBR) plants, many of which were in remote locations,
such as the plant recently installed in Pemberton, BC.. Sanitherm's
SaniBraneTM MBR plants produce exceptional effluent and are very easy to
operate, making them an ideal solution for remote locations. Meager Creek
Hot Springs, at an elevation of 5,000 feet, is an example of a very remote
location discharging into a pristine environment. Sanitherm's SaniBraneTM MBR
plants generate less sludge than traditional processes, a major advantage in
isolated locations. Of equal importance is the fact that the SaniBraneTM MBR
plant footprint is small, making it easier to get the plant in and out of
the site. Ease of operation is also an added benefit since trained operators
are not required at the site.
