Material can then be charged into a range of driers:

  • Paddle driers: Lodige (Stainless), Buss (Stainless)
  • Rotary Cone Driers: Pfaudler Balfour (Glass-Lined)

If required, we also have sieving and milling facilities


 Liquid Isolation and Separation
  • Stainless steel batch stills and high vacuum glass still
  • Hastelloy and stainless steel Luwa wiped film evaporators


waste 1Lianhetech Seal Sands has direct pipeline access to one of the largest municipal liquid aqueous waste disposal facilities in Europe at Northumbrian Water’s Bran Sands facility.


Our sister company, Fine Environmental Services, operates one of only three, third party licensed, high temperature thermal oxidisers for incineration of other waste streams e.g. halogenated, organics or contaminated aqueous streams.

We also have excellent transport links which allows easy road haulage of other materials that are not suitable for our on-site facilities.


  • warehouseWe have broad regulatory consent for storage of a wide range of materials in both bulk and drums.
  • A fully-fenced site with comprehensive CCTV coverage.
  • 24/7 site-based security and access control give us the ability to store and distribute Controlled Substances.
  • Specialised temperature-controlled storage in the range of -15°C to +30°C extends our capability.
