cyclonic separation of ballast water

Different Technologies For Ballast Water Treatment

Apr 03, 2020• Cyclonic Separation: Cyclonic Separation is used for those particles with a specific gravity greater than that of water. The particles get separated from the water due to centrifugal forces. It is normally done using hydro-cyclones. • Electro-Mechanical Separation: A flocculent is added that attaches to organisms and sediments. Get price

Dust purification techniques

Synonyms for cyclone separator are also substance cyclone, multi cyclone, vortex separation and wet cyclone. A cyclone is centrifugal separator where the particles are swung as a result of their mass by the centrifugal force to the outside. Entering air is automatically forced a rapidly spinning double vortex movement, so-called double-vortex. Get price

API oil–water separator

The API separator is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water properties.The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific gravity difference between the suspended solids Get price

Each separator contains 2 sepa-rate fluid outlets (1 reject stream, and 1 clear water stream) where the individual streams are captured and directed into individual piping headers located at the end of the separator module. After the cyclonic pre-treatment stage, the remaining Post-Cyclone stream may potentially contain Get price

Separator Housings

Use our centrifugal-action separator to remove grit, sand, metal chips, fines, and other heavy solids from liquids. Perfect for use as a pre-filter to extend the life of fine filtration systems. These units require little or no maintenance, as there are no moving parts to fail or wear out, or filter media to clean or replace. Get price

Cyclone / Demister Filter to filter Gas

The cyclone, like the demister, is used as pre-separator when the gas is expected to be highly contaminated by liquid and solid particles. The cyclone separates high solids content as well as high moisture content. The separation efficiency is based on centrifugal force, which carries the particles to the outer wall of the cyclone.
