Benefits of Electro-Osmosis Dehydration
1. Drier and Lighter
Improve sludge dryness of final cake by at least 20% compared to conventional dehydrator and reduce overall final cake weight by more than 50%.

Typical improvement on different types of sludge:
Sludge Reduction in water content * Reduction in cake weight *
Municipal WWTP <~20% 55% - 64%
Sewage WWTP ~20% 56% - 64%
Butchery WWTP ~19% 62% - 69%
Industrial WWTP 15% - 22% 50% - 70%
Paper Mill ~21% ~42%
* Actual result may vary according to sludge origin

Significant saving in:
Disposal cost Transportation cost
Storage cost Incineration cost

2. High Energy Efficiency
Low energy consumption of 58kW.h/ton to 128kW.h/ton of water dehydrated compared to average 975kW.hr/ton (750kW.hr/ton to 1200 kW.hr/ton) required by typical thermal dryers.



Parameters:
Input Sludge dryness 15DS% (85%wt%)
Sludge density : 1400 kg/m3
The min. & max. values are the average of all SELO models


Cost saving in:
Energy consumption Operating & maintenance cost
Incineration cost

3. Reduces Pathogens
Reduction in disposal cost due to improved biosolid quality and facilitates land-spreading
