The Comparision Between Physical and Chemical Water Treatment Methods

Comparison Item	Physical water treatment	Chemical water treatment
ROI	No need for secondary investment. Short investments return cycle.	Short duration and need continuous investment.
Energy conservation and emission reduction	De-scaling and anti-scaling. Maintain efficient heat exchange, saving energy and increasing production efficiency. No emissions, no pollution.	During the scaling process, it seriously affects the efficiency of heat exchange and wastes energy. And equipment needs a lot of water to dilute and wash, which wastes water resources.
Impact on equipment	Continuous working. It can not only remove scale, but also effectively avoid corrosion under equipment scale, extend the service life of equipment.	Treat only when scale is severe, ignoring the huge load of equipment in the process of scale accumulation, greatly shorten the service life of equipment/system.
Equipment maintenance and management	Reduce the times of equipment maintenance and no need for management.	Complex periodic maintenance, and with the cleaning of scale is not thorough, the times of maintenance increases year by year. Special person is required to take charge, waste time and productivity.
Side effects	Using permanent magnet technology, do not changing water quality.	Residual chemicals in water seriously affect water quality. Seriously affect on the living environment of human beings.
