Many manufacturing and metal finishers treat their metal bearing rinse waters through
conventional treatment with a gravity plate settler. However conventional treatment can
yield inconsistent metal discharge results. Microfiltration process effluent with proper
pre-treatment including coagulant additions yields very consistent metal discharge
numbers due to the nominal 0.1 micron rating that only allows particulate matter less
than 0.1 to pass through the microfilter membranes. The net result is a greater ability to
meet ever-tightening metal discharge limits. Furthermore, facilities that utilize this
technology as a pre-cursor for water recycle through reverse osmosis.
MEMKON MF Membrane Features:
Membranes are of a moulded design,
unlike others which are rolled from flat sheet into a
tube which then has a lengthwise seam, and thus a
Membranes are moulded from high
purity sintered polyethylene, and have the capability
of retaining all initial properties even after immersion
into bleach for a one year period. Competitor’s
membranes typically become brittle after about 30
days of immersion in bleach. Bleach is a very com
monly used cleaning agent, so corrosion resistance is
Membranes have tube walls that are
25-30% thicker and thus stronger and more
robust, than the competitor’s.
100% of their membranes using
an iron solution that is very colloidal. Colloids
are large but soft and spongy masses that will
pass through most membranes. Duraflow
quality testing will reject any membranes that
pass any of the colloidal iron through the
MEMKON MF System Features:
Will remove suspended solids from treated wastewater
down to 0.1 microns.
With the proper chemical treatment of the wastewater,
microfilter use will reduce sludge volume for filter pressing.
