Introduction

Our system of filtrate clarification works on sedimentation principle. We strongly believe that the “fundamental principle” of any filtrate clarification system should be – “the clarified filtrate should go directly to evaporator”.

By virtue of technology involved in filtrate clarification system used elsewhere i.e. “phospho Floatation” it is practically impossible to produce clarified filtrate worth of desired quality to be directly sent to evaporator. This is what precisely happens with this floatation type technology being in use at several places.

The critical deep study of this system and its failure to follow the “fundamental principle” rightly motivated us to invent the other only method of solid/liquid separation which is essentially “sedimentation” process.

First and foremost, the clarified filtrate from filtrate clarifier goes directly to evaporator station. In “Sedimentation Process”, 100% suspended impurities are removed.

Salient Features

• The clarity of clear juice resulting from filtrate clarifier is of superior nature and free from any suspended particles.
• ICUMSA colour value quite comparable with clear juice resulting from main juice clarifier.
• The purity rise from filtrate to clear juice is found in the range of 2 to 3 units.
• No increase in CaO content from filtrate juice to clear juice. In fact there is reduction in CaO content as actually observed.
• The mud resulting from clarifier is found to be quite compact and the thick mud is obtained resulting into better performance at vacuum filter.
• Due to separate treatment of filtrate considerable reduction in re-circulation of sugar as well as non-sugar is observed.
• Increase in the capacity of existing clarification house to the extent of 15 to 20%
• Increase in boiling house recovery due to increase in purity of filtrate juice to clarified filtrate juice.
• Improvement in colour value of sugar as good amount of coloured non sugars get precipitated at filtrate clarifier.
• Independence on any specialized proprietary chemicals as the process needs only conventional chemicals which are available at any sugar factory.
• As practically observed at our installations the keeping quality of the sugar found to be improved
• Very ideal for 25-30% plant expansion programme.
