Much improved gravity and coalescence separator
for removing solids and oil.
For comparison, traditional high-efficiency lamella separators
and CPT/ TPI separators separate particles only to a minimum size
of 50-70 micron.
The flow through the plate pack is horizontal, causing the solids
to accumulate, become larger and drop through special openings
into an area where there is no flow. They remain in this area
until they are removed. Therefore, once separated out, the solids
remain in the separator and are not washed out of the overflow
by the next shower of rain. This makes a flow limiter unnecessary
and allows the separator to also work when the flow rate is higher.
The separator can be used for gravitational flow applications
and for applications where a pump is required. Any drops of oil
coagulate and rise along the underneath of the plates through
the weep holes in the plate packs.
