2. Principle of Operation: Non Mixing Liquids separate based on their Density difference. Rate of separation is dependent on the residence time provided and on the laminar nature of the flow. Lower Density liquid floats on the top. Higher density liquid settles down at the bottom.

3. Desorber Needs and advantages: Needs: Two different liquids to be separated. Separation of two liquids to be continuous. Advantages: Simple, easy and cost effective. Best alternative to conventional skimmers like Belt/ Disc and Rope skimmers which require settling tanks. Gravity operated and hence no electricity required. Mobile unit: A single unit can be used for a variety of applications. No restriction on type of liquid used. Used for all applications involving separation of two non miscible liquids with specific density difference.

4. Comparison between Skimmer and Desorber: Designed, Manufactured and serviced by us and all parts are indigenous. Most skimmers are imported and spare/ service availability is worrisome Oil removal is not dependent on the contact parts of the Desorber. Efficiency is highly dependent on the belt/ disc/ rope and any defect in the above will result in poor performance Skimming tank not required hence compact Space required is more because of skimming tank Gravity fedElectricity is a must to run the skimmer No such prerequisite conditionMost skimmers offered requires oil to come near the belt for effective oil removal and dependent on the skimming tank size No Skimming tank requiredLot of residence time in skimming tank required Faster Oil separationTime Consuming DesorberConventional Skimmer
