About the Solution:
The ThickTech™ Rotary Drum Thickener (RDT) is the industry leading sludge thickener. Its performance is unmatched, with sludge volume reduction of 90% and a 98% capture rate. In addition, this superior performance is achieved with very low amounts of polymer. The ThickTech™ system is quite compact and requires less floor space than other thickeners. It has low requirements for horsepower, water consumption and polymer usage, resulting in valuable operational efficiencies.
The ThickTech™ RDT increases digester capacity, reduces hauling costs and can be used as a pre-thickener to increase capacity of other dewatering equipment.
Solution Strengths, Weaknesses and Critical Indicators
NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.
General Support & Other:
- Can be an integral part of many manure management systems
- Most projects have at least some equipment that supports operations of the main technology
- This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.
Coarse solids separation technologies:
- Produces fiber for bedding, soil amendment and compost
- Used extensively on dairies across the country to reduce storage and application concerns
- Does not significantly reduce nutrients from the manure stream
- Can utilize many types of technology like slope screen, screw press, rotary drum and others
- Used before many other technologies to remove coarse solids
- Minimal maintenance and operator time required
