Project	①M⁺FLO magnetic flocculation sedimentation tank	②DENSADEG high-density sedimentation tank
Technical inventor	Qingdao Pacific Chemical equipment Company	French Deliman water treatment company
Technical characteristics	Adding magnetic flocculation clarification technology, adding magnetic powder to strengthen the flocculation and purification effect, magnetic flocculation high-speed precipitation separation	Mechanical coagulation/flocculation, efficient precipitation separation, through the return sludge to enhance the flocculation and purification effect
Surface load	20-45m³/(m²*h)	5-15 m3/(m2*h)
System residence time	About 15 minutes	About 45 minutes
SS removal	60-95%, sewage depth treatment SS<3mg/L	50-85%, the sewage depth treatment can reach SS<10mg/L
TP removal	Magnetic floc can adsorb aluminum phosphate/iron colloidal, magnetic floc high-speed precipitation, TP0.1mg/L (stable)	Aluminum phosphate/iron salt colloid slight, not easy to flocculate precipitation, up to TP<0.5mg/L (unstable)
Allowable water intake SS	~3000mg/L	~1000mg/L
Shock load resistance	excellent	normal
Pharmaceutical consumption	Slightly lower than ②	lower
Running cost	0.07-0.09 yuan/ton water (pharmaceutical, magnetic powder, power consumption)	0.08-0.11 yuan/ton water (pharmaceutical, power consumption)
Floor plan	A	3A
Project investment	Equivalent to ②, add magnetic flocculation sedimentation tank civil construction and shading shed + equipment	Equivalent to ①, high-density pool civil construction and shading shed + equipment
Quasi-iii /IV standard process	M+FLO magnetic flocculation sedimentation tank/single process	High-density sedimentation tank + filter/dual process combination
