Super high-loading coagulation system
The coagulating sedimentation process is among the most commonly used water treatment processes in which a flocculant or similar material is added to inflowing water to agglutinate fine particles (SS) into flocs. Solids and liquids are then separated to produce clean processed water.
The following illustration shows a typical facility set-up. Due to growing space restrictions in recent years, demand is growing for space-saving equipment. This product meets just this need.
SUMI-THICKENER
Distribution-type super high-loading coagulation equipment
SUMI-THICKENER is a compact, high-speed thickener one-half to one-third the size of a conventional coagulating sedimentation tank. We achieved these dimensions by using a distributor to disperse inflowing water and create uniform ascending currents.
Features of SUMI-THICKENER
Space-saving unit as small as one-half to one-third of the size of conventional coagulating sedimentation systems
The distributor disperses inflowing water to prevent irregular flows. This system can perform treatment using high surface loading.
Integration of coagulation tank and coagulating sedimentation tank
The mixing chamber inside the tank is used to promote reactions with high-molecular flocculant, eliminating the need for a coagulation tank. The system can be installed in confined spaces.
Coagulated flocs with excellent settling performance
The system minimizes fine flocs and forms uniform coagulated flocs by adding a high-molecular flocculant at appropriate intervals.
No damage to coagulated flocs
Coagulated flocs formed in mixing chamber are supplied to the tank without damage caused by water current shearing forces.

SUMI-THICKENER Zone Separator Model
Floc filtration-type high-speed clarifier
The SUMI-THICKENER Z high-speed clarifier is just one-fifth to one-tenth the size of a conventional coagulating sedimentation tank because it forms a floc layer (sludge blanket) inside the tank. The system combines high-speed treatment and floc filtration to provide clean processed water.

Features of SUMI-THICKENER Z
Equivalent performance with far smaller footprint as compared to conventional sand filter.
SUMI-THICKENER Z forms a floc layer (sludge blanket) that filters and captures minute particles and enlarges flocs. It provides clean processed water using high surface loading.
Examples of SUMI-THICKENER Z application
Significant space savings can be achieved by replacing existing coagulating sedimentation and sand filtration equipment with a single set of coagulating sedimentation equipment.
The flowing motion of the sludge blanket promotes the coagulation of existing flocs and particles in the inflowing water. This means no coagulation tank is required.
