CYCLONE DRYER
FROM LIQUIFIED SLUDGE TO SOLID SLUDGE
FREE ADJUSTMENT OF MOISTURE CONTENT OF DRIED PRODUCT !
The surplus sludge which is produced by the treatment of waste water from the activated sludge consists of cell-bearing bio-bacteria. Traditionally, this surplus sludge was processed as fermented fertilizer through adjustment of the moisture content. However, this process takes 2~4 months for complete ageing. The Okadora Dryer, however, broke completely new ground with its ‘Boil & Dry’ system. The process works by completely breaking down the cell structure and adjusting moisture content by 50%. Using the Okadora process, the dried product is reduced by 1/3 in volume and fermented to full maturity in only 6~8 days. When it comes to preservation of the dried product, the traditional product (with 10% moisture content from the normal direct heating dryer), returns to the pre-dried sludge condition when it is immersed in water. On the contrary, the dried product from the Okadora system remains as it is. It does not change condition, thereby allowing for the optimum application of fertilizer.
