Description
1 Company Profile
BeijingTri-High
Membrane
Technology Company is a manufacturer of water treatment products of
top quality, founded in ***3. Tri-High has varies of water
treatment products such as capillary UF
membranes,tubular UF
membrane, RO
housing,FRP
Tank and Valve, ion exchange
resins,water purifier, filter
media of quartz sand, birm,
anthracite, etc. The core products are UF membranes cooperated with
Berghof of Germany, which has a good reputation for industrial
waste water treatment in China and other countries for its stable
performance and long lifetime.
Tri-High’s
products have been widely used in USA, Europe, Japan, Thailand,
Mexico, Korea, mid-east, south Asia, Australia, etc for hundreds
reference through its distributor and partner net work in those
countries, especially for industrial waste water
reuse.
Tri-High
pursues a long
term and stable cooperation relationship with our distributors and
partners by continuous improvement of quality and service. We are
looking for more partners and distributors for common development
by taking advantage of both sides.

2.1Technological
process
Technological process is as
follows:
Feed water pool→ Feed water pump（2tph）→Surfaced in the gas oil
device→Booster pump（2tph）→UF System→Middle water
tank（***0L）→High
press pump（2tph）→RO system（2tph）→Reuse water
tank(**0L）→Permeate water
Flocculant dosing
system (Chemical tank, Metric pump)→
Fungicide dosing
system (Chemical tank, Metric pump)→
Scale inhibitor
dosing system (Chemical tank, Metric pump)→
Reductant dosing
system (Chemical tank, Metric pump)→
Chemical cleaning
system (dosing tank, cleaning pump, cleaning filter, cleaning tube,
backflow agitating tube)→
Instrument
monitoring system (pressure monitoring, flow monitoring,
desalination rate of RO monitoring, oxidation-reduction potential
monitoring)→

control system (liquid level control, RO self-cleaning
control)
2.2.1.1 Pipeline filter
The pipeline filter is mainly
used for the removal of large particles impurities and suspended
with a filtration accuracy of*0 mesh to protect the following
tubular UF. This filter is
directly installed in the line to guarantee the safety of
operation.
2.2.1.2 Tubular UF
Tubular
UFmembrane is made
of PVDF with hydrophilicity, acid and alkali resistance, corrosion
resistance and high flux (details see table 2 Tubular UF module
parameters). The internal compression type tubular
UFmembrane
operation includes three procedures: filtering, flush, regular
chemical cleaning.
