Static clarifiers<\/strong>, also defined as static sedimentation units, are designed to provide a simple, reliable, and continuous solution for solid-liquid separation in industrial processes. Based on a natural sedimentation principle (gravity force), they operate without moving parts, reducing operating costs and ensuring maximum long-term operational continuity.<\/p>

Components in contact with the material can be manufactured with different finishes, depending on the characteristics of the product to be treated.<\/p>

Thanks to their simple design and quick installation, Poggi static clarifiers can be easily integrated into new or existing systems. They can be directly connected to extraction pumps, sludge silos, filter presses, or collection tanks, making them ideal for aggregate washing plants, industrial wastewater treatment, environmental recycling, and many other applications.<\/p>

Versatile, robust, and efficient, they represent a smart choice for those seeking reliability, simplified management, and a low-energy solution.<\/p>

Static clarifiers or sedimentation units represent an effective and efficient solution<\/strong> for water treatment, significantly improving water quality through a simple and natural separation process.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Operation and safety<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

In static clarifiers<\/strong>, the water to be treated is introduced at the top of the unit and conveyed into a central vertical cylinder, also known as a stilling pipe, which extends to the bottom of the tank. This system guides the flow downward and controls its upward movement, ensuring uniform distribution and a stable upward flow regime.<\/p>

In this way, turbulence is reduced, progressive sedimentation of solid particles is promoted, and separation efficiency is improved. Sludge accumulates at the conical bottom, from which it can be discharged through a lower outlet.<\/p>

The clarified water rises to the top and is collected through overflow channels positioned along the perimeter. From here, it can be directed to subsequent treatment stages or to storage tanks. The process operates continuously.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

CLARIFIED WATER COLLECTION<\/h3>\n
\n

At the top of the static clarifier, the weir is installed a perimeter overflow system designed to collect clarified water at the end of the separation process. As the water slowly rises through the tank under controlled flow conditions, it reaches the weir uniformly, without turbulence, ensuring a steady and continuous collection of the treated liquid.<\/p>

From the weir, the clarified water is conveyed into a discharge pipe located outside the clarifier, through which it can be directed to storage tanks, process recirculation, or subsequent treatment stages. The geometry and configuration of the weir are designed to maintain a constant level and maximize the effective overflow surface, optimizing the overall efficiency of the system.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

SLUDGE CONE AND FLOCCULANT DOSING INLET<\/h3>\n
\n

> In the discharge cone, located at the bottom of the static clarifier, the solids separated from the upward flow accumulate. This area represents the point of highest concentration of the settled material and can be configured for the controlled introduction of flocculants.
The addition of flocculants, through dosing systems available on request, improves separation efficiency by promoting the aggregation of fine particles and accelerating sedimentation. This solution is particularly effective in the presence of light sludge or low-density suspensions and allows optimized discharge and management of residuals.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

DIFFUSER CYLINDER<\/h3>\n
\n

> At the base of the central cylinder, where water enters the static clarifier, the diffuser cylinder is installed\u2014a key component designed to ensure uniform and controlled distribution of the incoming flow.<\/p>

The diffuser slows down and equalizes the upward flow, eliminating direct currents that could compromise sedimentation. Thanks to this geometry, the water begins to rise evenly and at a reduced velocity, creating ideal conditions for the separation of solid particles.<\/p>

The diffuser cylinder therefore helps stabilize the internal flow, reduce turbulence, and increase the efficiency of the clarifier, even in the presence of variable loads or particularly fine materials.<\/p> <\/div>\n <\/div>\n <\/div>\n <\/div>\n

The settled materials are evacuated through a discharge outlet located at the bottom of the clarifier. The system is designed to be directly connected to pumps, sludge silos, or dewatering systems.<\/p>

SLUDGE FLOW MANAGEMENT<\/strong><\/span>
The discharge can be continuous or cyclically controlled, depending on the flow rate and downstream process. The operator can regulate emptying through valves, timers, or remote controls, according to plant requirements.<\/p>

PROCESS STABILITY<\/strong><\/span>
The absence of moving parts ensures operational continuity, minimizing failures, blockages, and maintenance requirements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
