Industrial Silt, Sand & Sediment Removal

Our core focus is liquid / solids separation. Our technologies range from trash removal from stormwater runoff to separating solids as small as 75 micron from various types of sludge. Whatever your process liquids are, there’s a good chance we can provide a solution that will make your operation more efficient and lower your operating costs. If you’ve got solids you want to get out of your flows – we can help, contact Hydro International today! 

Virtually any industrial manufacturing process can benefit from liquid / solids separation. Hydro International offers a suite of technologies that, simply put, are the best performing liquid / solid separation systems on the market. In 1976 we invented the world's first high performance vortex sand removal system - TeaCup® which has led the industry in capturing more and finer sand than other types of technologies ever since. We have continued to expand our portfolio, developing additional sand, sediment, grit and silt removal technologies for other applications, operating conditions, improved performance, and reduced footprint. 

By-Product Recovery 

Any industrial process that uses a lot of water typically has a significant amount of by-product that is wasted and washed into wastewater streams. Whether it is the fines left from steel manufacturing, or scraps of ingredients after a burrito leaves the line – this residual material can either be a nuisance or a treasure. If left to enter other processes, it can damage downstream equipment or reduce the capacity of liquid-based wastewater treatment processes. If sent to a sewer system, it can trigger astronomical surcharge fees

Sand & Grit Removal for Flume Waters

When dealing with anything grown in the soil, producers must deal with dirt, sand, and grit. In sorting, trimming, and grading, there's a lot of moving parts. Equipment such as conveyors, pumps, scrapers, spray nozzles, and material handling equipment all can be seriously damaged by fine particles and abrasive sand. Traditionally, sedimentation basins have been used to settle out these materials from vegetable washing operations.

There are numerous problems with this type of approach. Removing materials from these lagoons is expensive, labor intensive, and often quite dangerous. Often the biggest problem is the tremendous amount of land required to remove sediment. Growers and harvesters could use that land for much more profitable purposes. Hydro International offers small footprint, mobile solutions for flume degritting that outputs dry sediment that is ready for cost-effective disposal

Hydro International’s sand and grit removal equipment has been used in a wide variety of operations to help quickly recycle wash water and re-use this valuable commodity for additional washing or irrigation. 

Our TeaCup® grit removal system was originally developed to remove sand from vegetable harvest washing operations in 1976. Many of our other technologies such as the HeadCell®, Grit King®, and Grit Snail® - have also been adapted to meet the needs of industrial operations. 

We can help you with:

  • Flume degritting
  • Wash water reuse
  • Sediment system capacity protection and land reuse
  • Root crop harvest washing
