Main effect
- Prevent or remove scale strongly
Such as cooling towers or boilers in new水系System W / E to install the preview release, Silica, etc. attached Scale is effective in preventing breakthrough. - Remove rust and prevent corrosion strongly
Water Energizers prevents rust and corrosion in a system and protects the metals in the system. - Soften and remove scale
Installing Water Energizers softens scales like silica, which are firmly attached in a water system within weeks ~ months to easily remove them by air or water hose. - Prevent or remove general bacillus like bacteria
Water Energizers prevents and restricts the increase general bacilli such as bacteria, slime, and seaweeds, which are tolerant to chemicals and removes them. - BOD (Bio-Chemical Oxygen Demand) Reduction
Other effect
- Turbidity, transparency, and chromaticity are significantly
- Iron, calcium, and silica in water decrease magnificently.
- Sedimentation speed of suspended solids increases.
Economical Efficiency
- Little energy
Energy cost is reduced. - Small repair cost
Cost of water treatment chemicals is decreased. Labor costs of preventative and repair work such as scale removal and chemicals management and other costs for regular maintenance and system stopping can be reduced. - Little water (Reuse of coolant)
To manage chemical concentration of coolants, water blow reduces forcibly to decrease the supply of coolant. Because water quality is improved, the ratio of recycle of industrial water increases. - Small product cost
Error rate of product quality decreases by stabilizing the cooling capacity of heat exchanger. - Small equipment cost
Life of water system (like pipe) increases.

Relation between scale thickness and fuel loss
Fuel loss caused by scale depends on the status of pipe and raw water. However, there is a close connection between scale thickness and fuel loss.
