Olive Oil / Olive Processing

We can help you recover valuable pomace and produce dewatered output that reduces your hauling and handling costs. Additionally, removing these solids from your waste stream gives you options for water reuse, and reduces your wastewater treatment processing needs.

Pomace Recovery and Plant Water Re-Use

The timing of harvest is critical to make high quality extra virgin olive oil. To be top-shelf product, olives may need to be processed the same day they are harvested. High volume production within a compressed timeframe can lead to surcharge fees if your plant is not ready. Reusing water, optimizing wastewater treatment, and recovering by-product for sale as animal feed are critical efficiency and cost saving issues for olive oil producers.

The Hydro MicroScreen™ can help - and the system often pays for itself in reduced disposal and treatment costs alone in just a single season.

Olive Oil Washwater Treatment for Water Reuse 

Olive oil production requires a tremendous amount of water to wash dirt and other impurities from harvested olives to prepare for pressing. If discharged directly wash water has the potential to overwhelm sewer treatment systems. Ideally that process water can be reused to irrigate olive groves or other crops.

However, wastewater that contains solids will clog diffusers and irrigation systems if left untreated. Additionally, problematic Biological Oxygen Demand (BOD) needs to be reduced before that water is suitable for irrigation purposes. Often wastewater is sent to large settling tanks to allow solids to settle out to make usable irrigation water.

This process leads to a massive amount of settled material that is difficult and expensive to deal with. Some olive oil producers have no other choice but to landfill this heavy, high-volume, high water content residual material from their settling tanks. Transportation costs, fuel costs, and landfill fees add up very quickly. The Hydro MicroScreen™ ultrafine rotating belt filtration system provides a better solution,

Hydro MicroScreen™ Can Help!

  • Reduces solids sent to sedimentation systems which increases their capacity
  • Reduces particulate BOD and TSS which reduces the need for downstream treatment processes
  • Outputs dewatered product with low water content, which provides alternative disposal options or at least reduces the weight and volume that needs to be trucked to landfill
  • Allows you to recapture / reuse more of your water faster 

Olive Oil By-Product Removal and Compaction

After olive oil production, 80% of olives remain as a by-product. This material still has value, but conventional recovery methods reduce the profitability of this by-product to use as animal feed. Often entrained in a slurry with a significant amount of viscous and heavy oil and water, making it difficult to deal with and expensive to transport. 

The Hydro MicroScreen™ helps you recover this valuable material much more efficiently as a relatively dry product that can be cost-effectively sold and transported to end-users in a wider geographic area than was previously profitable.

Hydro MicroScreen™ Can Help!

  • Effectively recaptures pomace waste from fruit wash water, CIP, & equipment cleaning water
  • Outputs drier compacted materials which significantly reduce hauling costs for pomace as a waste or by-product
