Company
Biography
Rochem provides equipment and services for the recovery of high-quality
water and the removal of toxic contaminants from industrial
and process waste water streams. Rochem's Vision is to be a
primary source of key process separation technologies and services
for ships at sea, refiners, chemical manufacturers and other
companies with difficult-to-handle petroleum/petrochemical waste
water streams. Rochem will endeavor to combine innovative process
engineering strategies with synergistic technologies to provide
customers the most beneficial, cost-effective system options
for meeting their needs.
Corporate Profile
The ROCHEM group of companies was founded in 1973. Its vision
was to serve the needs of marine customers in the marine chemical
and maintenance field in all major ports worldwide. Today, marine
installations exist in over 50 countries. Additionally, ROCHEM
has expanded to include numerous non-marine industrial projects.
ROCHEM first introduced Reverse Osmosis into its product line
in 1982 when in began marketing its G4 module. The introduction
followed licensing of the G4's plate technology by GKSS. At
the time, ship owners were having operational difficulties with
competitive RO technologies. This led ROCHEM RO WASSERBEHANDLUNG
GMBH to embark upon a research and development program to produce
a membrane module. In 1986, the project resulted in the Disc
Tube (DT) Module Technology that received worldwide patent coverage.
ROCHEM'S DT Module uses a unique membrane module construction
that results in an open channel, unrestricted and fully turbulent
feed water cross-flow system configuration. The turbulence prevents
suspended solids carried in the feed water from being trapped
or settling inside the membrane module. As a result, infrequent
and highly successful maintenance cleaning of the membrane is
achieved using a standard inbuilt cleaning system. Unlike other
RO systems, the need for pre-treatment of seawater feed with
acid or other chemicals is eliminated. The system guarantees
full performance, high reliability and greatly extended membrane
life.The
ROCHEM RO plants are shipboard system favorites. Over 1200 installations
with varying capacities ranging from small vessels to the very
largest, including the NATO Navies, are in daily use all over
the world. Their modular construction allows the flexibility
to make system design and installation relatively easy on any
vessel. Certified by all well-known Classification Societies,
the systems provide fully automatic operation and are easy to
maintain.
ROCHEM is unique because of its multi-faceted approach to effective
filtration. The ROCHEM GROUP combines the following to produce
outstanding systems:
The
expertise gained from its experience in the marine industry
has enabled ROCHEM to design and build RO Systems for other
applications such as industrial plants and hotels. In 1989,
ROCHEM entered the industrial leachate (liquid toxic waste)
treatment market for landfill locations, one of which was Schonberg,
the largest waste disposal site in Europe. Due to its DT Module
Technology and advanced plant technology, ROCHEM quickly became
a leader in the market reaching over $40 million in sales with
150 employees in 21 countries.
At the beginning of 1998, PALL Corp. USA, one of the largest
suppliers of filtration equipment in the world, acquired the
right to market certain ROCHEM products including its DT technology.
PALL established PALL ROCHEM WASSERTECHNIK, headquartered in
Hamburg, to promote and sell RO systems worldwide.
Meanwhile, the ROCHEM Group was using the knowledge and experience
gained through its leachate installations to develop new REVERSE
OSMOSIS, NANOFILTRATION and ULTRAFILTRATION technologies. Existing
ultrafiltration systems on the market were beset with problems
in attempting to treat wastewater containing fouling impurities
and suspended solids. It developed its new-patented membrane
module to add to its line of products. Known as the FM MODULE,
this new technology can address special requirements such as
the treatment of Grey Water on ships to meet environmental discharge
requirements. The FM Module is also used to treat and convert
surface water to drinking water on shore.
The ROCHEM Group established the ROCHEM UF SYSTEME GmbH, located
in Hamburg in 1998, to promote and sell BIOFILT®, a newly
designed BIOREACTOR. Its special treatment technology is intended
to replace conventional aerobic biological sewage plants aboard
ships. Based on a high-density biological process combined with
a UF Membrane System, BIOFILT will produce a pure, clean discharge
without requiring additional chlorination or other chemical
treatment. By treating all wastewater and sewage water on sea-going
ships with BIOFILT before discharge overboard, marine life and
organisms will be protected and a truly "Environmentally
Sound Ship" is achievable.
ROCHEM products are available through a number of subsidiary
companies and agents worldwide.
