Process Optimization of Effective Partition Constant in Progressive Freeze Concentration of Wastewater

Effect of Flowrate and Coolant Temperature on the Efficiency of Progressive Freeze Concentration on Simulated Wastewater

Freeze concentration freezes or crystallises the water molecules out as ice crystals and leaves behind a highly concentrated solution. In conventional suspension freeze concentration where ice crystals formed as a suspension in the mother liquor, separation of ice is difficult. The size of the ice crystals is still very limited which will require usage of scraped surface heat exchangers, which ...

Prevention of Initial Supercooling in Progressive Freeze-concentration.

A physical method is proposed that uses a cooling plate with many small holes to prevent initial supercooling in progressive freeze-concentration, and thus avoid serious contamination of the ice produced. The higher chance for ice nucleation of the water molecules in the holes due to the temperature gradient in the cooling plate resulted in the initial supercooling being completely prevented. A...

Task 2.6: Mechanical Freeze/Thaw and Freeze Concentration of Water and Wastewater Residuals

Optimization of Coagulation and Flocculation Process in Wastewater Treatment of the Food Industry: A Laboratory Study

Background and Objectives: Food industry wastewater has a high pollution load, which is due to water consumption at various stages. In the absence of adequate wastewater management and supervision of the food industry, this wastewater can be considered as a source of environmental pollution. This study aimed to optimize the coagulation and flocculation process for the treatment of food industry...

Optimization of factors affecting the application of Fenton process in sofa and detergent wastewater treatment

Introduction: Most commercial surfactants used for cleaning (as detergents (are part of xezenbiotic compounds. These compounds and products due to its toxic effects on aquatic organisms may interfere with hormonal system and consequently change the echo system. Since the biodegradation of those compounds are weak, ordinary methods are unable to break down conventional purification. Therefore, t...
