Generating "Revinu"

Lime stabilization is a proven, EPA-approved method for treating sewage sludge. In the capable hands of Schwing Bioset, the technique of lime addition has gone from effective to exceptional.

Bioset's process optimizes the chemical requirements and system efficiencies of lime stabilization. The end product, called Revinu, is safe and has many uses including fertilizer and as a soil stabilizer. Revinu is inexpensive and reliable, and produces a readily usable and valuable Class AA product.

Compared to other methods of producing Class AA material, the Bioset process is affordable from both initial capital expenditures and ongoing operation and maintenance costs. The equipment is fully automated and requires very little operator time. As a Class AA biosolid, the end product can be widely used and handled without many of the restrictions imposed on a Class B product.

Revinu's nutrient composition is a strong selling point. First, Revinu's low phosphorus content means it can be applied in phosphorus-sensitive areas. Second, Revinu provides a slow-release alternative to commercial nitrogen, which gives consumers three times the amount of nitrogen breakdown for prolonged plant nutrition. Third, Revinu provides sufficient potassium-a nutrient that is often prohibitively expensive-to support root growth and proper seed germination for a fraction of the market price of potassium.

Finally, Revinu is made up of 35% to 55% organic humus. The humus in the material acts as a topsoil, replenishing the natural bacteria that are essential for optimal plant growth and root strength. Until Revinu arrived on the market, landowners were often unable to replace eroded topsoil due to the astronomical cost associated with the process. Revinu makes topsoil replenishment accessible and affordable.

In short, the Bioset process is the most versatile and attractive method for biosolids treatment on the market today.
