Revolutionizing Wastewater Treatment With Rare Earth Chemistry
Our Mission
Driven By Purpose. Powered By American Innovation.
Stiltskem was born out of a vision more than 30 years ago—to create better, smarter, and more sustainable solutions for wastewater treatment in this country. For decades, municipalities have struggled to balance shrinking budgets, rising sludge disposal costs, and increasingly strict effluent limits. The tools were limited—until now.
How SK300 Transforms Wastewater Treatment
Performance That Speaks for Itself
SK300 is Stiltskem’s premier rare earth based coagulant, engineered to transform municipal wastewater treatment through performance, sustainability, and reliability. Developed as a modern replacement for outdated coagulants like alum and ferric chloride, SK300 delivers superior phosphorus removal, reduced sludge generation, and comprehensive operational advantages.
Smarter Water Chemistry For Real-World Impact
Advanced Coagulation
Achieve unparalleled results with SK300 and SK856M.
Advanced Coagulation
In contrast to traditional chemistries, our rare earth formulations produce cleaner, faster, and more stable coagulation for industrial water treatment companies and municipal wastewater systems.
Sludge Reduction
Say goodbye to hauling headaches with sludge reduction!
Sludge Reduction
Our coagulants can reduce sludge up to 50%, allowing the client to cut down disposal costs and improve plant efficiency. This is a smarter way to recycle water that actually works.
Soil-Safe Sludge
Our non-toxic aluminum-free sludge has a more environmentally friendly profile for land application.
Soil-Safe Sludge
Our trace rare earth elements have even shown improve soil and plant health. This is another win for compliance and sustainability in water treatment and supply.
Resource Recovery
Traditional coagulants often damage or denature valuable byproducts like protein, fat, and nutrients, rendering them unusable and sending potential revenue down the drain.
Resource Recovery
Stiltskem’s rare earth chemistry preserves the integrity of recoverable components, enabling facilities—especially in food and industrial sectors—to reclaim useful materials from their waste streams.
