Thin film slude dryer

LCI’s thin film sludge dryers can accept a wide range of sludge types such as digested or undigested sludge, primary and/or secondary sludge, industrial sludge, sludge with high amounts of high strength waste or Biomass, sludge which is poorly dewatered, “sticky” sludges, and more.


Safety is paramount when drying sludge. Dried sludge is combustible and therefore needs to be treated as such. The highest risk for fire and explosion is generally the combustible dust from the drying process. LCI and our parent company Nederman have vast experience in explosive dust applications and the NFPA (National Fire Protection Association) codes surrounding dust applications.


One of the highest operational cost associated with Sludge Drying is the thermal and electrical energy to dry the material. Increases in efficiency associated with energy consumption can significantly reduce the cost of operating a dryer system. Due to the “Thin Film” design of our dryer, LCI can boast of having one of the highest thermal and electrical efficiencies on the market.

End Product

The product discharged from a drying system is very important as to the end use of the dried material. The characteristics of the end product are different depending on the application the material is used in. LCI’s experience in the granulation market make us a perfect partner to assist in developing a dryer system which can generate the end product the application requires.

Emissions Control

Dryers release moisture which contains different compounds which must be considered. With ever increasing air standards it is important to understand and treat the moisture released from a dryer system. LCI’s parent company, Nederman, is know as the “Clean Air Company” and our sister company Mikropul specializes in Industrial Air Filtration so LCI has the experience to assist in the emissions control requirements of drying applications.
