Hydro Quip - Inclined Plate Clarifier with Mix & Flocc Tank
The continuous flow Inclined Plate Clarifier with Mix & Flocc Tank separates mechanical and chemical emulsions and colloidal contaminants from wastewater as a single flow-through operation. The use of polymers or other chemical additives will help precipitate the contaminants to the hopper compartment for removal.
The Chemical/Physical Inclined Plate Clarifier (CPIPC), along with the addition of polymers, will break emulsions and separate suspended materials in the wastewater. The CPIPC is designed with a rapid mix reaction tank and a slow mix floc tank prior to a series of inclined plates. The plates are placed at either a 45 or 55 degree angle. This specialized design allows the system to perform all the functions of a chemical emulsion breaking system along with clarification and removal of solids in one operation.
Each unit shall be designed and complete with: (1) Reaction Mix Floc Tank, (1) Slow Mix Floc Tank, (1) Separation Chamber, (1) Sludge Chamber and (1) Clean Water Chamber.
Reaction Mix Floc Tank
The raw wastewater enters the system through a non-clogging inlet nozzle to the reaction tank. Here, the wastewater is dispersed into rapidly churning blades of a variable speed, high sheer mixer. Emulsion breaking chemicals are dispensed into the turbulent waters via a variable speed, dry feed, spring coil auger. The reaction tank capacity is designed to allow for sufficient mixing of the chemicals within the wastewater before flowing into the slow mix floc tank.
Slow Mix Floc Tank
The chemically- infused wastewater underflows from the reaction tank into the slow swirling blades of a second variable speed mixer. As the emulsion breaking chemicals react and hydrate, freed oil particles and suspended solids join to produce small "pin" floc. As the floc grows, there is a noticeable separation of swirling floc and clear water. The floc tank capacity is designed to allow effective adsorption and sufficient expansion of the floc sludge cluster. As the slow mixer swirls, the sludge will overflow into the separation chamber.
Separation Chamber
The sludge will flow down under the plate pack skirt and move upward towards the parallel plates. As the wastewater moves upward, the inclined plates will interrupt the sludge particles velocity. The particles will begin to slide down the plates, colliding with other particles and growing larger. This increases their downward motion into the sludge hopper.
Sludge Chamber
The sludge chamber, also known as the sludge hopper, collects the sludge as it settles. Intermittent clean water spray nozzles are placed within the cone shaped hopper. These will lightly agitate the densely settled sludge, making it easier to be removed during the sludge pumping cycle.
Clean Water Chamber
The clarified water exits the top of the plate pack free of its suspended solids and "overflows" the effluent weir. From this point the clarified effluent flows by gravity and exits the unit through the effluent nozzles.
