Flocculant Mixing System

The flocculant mixing system uses an automated control system to precisely dose chemicals (such as flocculants, disinfectants, and pH regulators). It is widely used in water treatment, chemical processing, and power generation. The system primarily includes a chemical storage tank, mixing system, metering pump, control cabinet, and pipeline valves, supporting fully automated processing of both dry powder and liquid chemicals.

Technical Features:

Precise Dosing: Utilizing PLC or intelligent instrumentation, the dosing rate is adjusted in real-time based on water quality parameters (such as pH and turbidity).

Flexible Configuration: A variety of chemical dosing units (such as PAC, PAM, and sodium hypochlorite) can be integrated to meet diverse process requirements.

Corrosion-Resistant Design: Key components are constructed from PE/PP or 316L stainless steel, making them suitable for use in highly acidic and alkaline environments.

Energy-Efficient: Equipped with a variable-frequency-controlled metering pump to reduce energy consumption.

The fully automatic dosing device mainly consists of an intelligent control box, a mechanical diaphragm metering pump, a dosing barrel, and a liquid level switch (optional components include a conductivity meter, pH meter, ORP meter, corrosion rate meter, turbidity meter, and drain valve).

Intelligent Control Box: The intelligent control box serves as the brain and control center of the entire dosing system, coordinating the work of all components. It uses a two-way output time-controlled switch.

(1) Online control of the opening and closing of the dosing pump.

(2) Online monitoring of the remaining amount of agent in the dosing system barrel, with an alarm signal triggered when the liquid level is low.

Mechanical Diaphragm Metering Pump: When the intelligent control reaches the preset time, the metering pump activates and begins dosing. Once the time end value is reached, the pump stops dosing. The mechanical diaphragm metering pump is a high-quality domestic brand known for its stable performance, accurate and uniform dosing, corrosion resistance, good sealing, compact size, and high metering accuracy. The dosing amount and output pressure can be adjusted steplessly to suit the actual site requirements.

PE Anti-Aging Dosing Barrel: The dosing barrel serves as a container for water treatment chemicals. Made from round, anti-aging PE material, it resists brittleness and cracking, with a service life exceeding 10 years. Specifically designed for automatic dosing systems, it offers exceptional rigidity and maintains its shape even when fully loaded. Its translucent surface allows for easy visibility of the remaining chemical level. The high rigidity of the barrel cover provides ample support and space for mounting a metering pump, low-level alarm, and optional liquid mixer.

Low-Level Alarm: The dosing barrel volume is fixed, but the dosing time and amount are variable. This makes it difficult for the on-duty engineer to accurately monitor the remaining chemical level and replenish it on time. Without replenishment, the chemical may run out, causing the dosing pump to run dry. If the pump runs dry for an extended period, it may damage the pump and affect the system's dosing performance. The low liquid level alarm system generates an alert when the reagent in the tank reaches the low level, notifying the engineer to refill the tank and prevent damage.

Conductivity Meter (Optional): The circulating water system uses municipal tap water, which has a fixed conductivity value upon leaving the factory. During operation, the system continuously evaporates and concentrates, increasing the conductivity of the water. Excessively high conductivity can be harmful to the circulating water system. The conductivity meter is used to monitor the degree of evaporation and concentration in the system. The ratio of the post-operation conductivity of the circulating water to the initial conductivity of municipal tap water is called the concentration factor. Effective control of this conductivity is crucial to maintaining the system's proper functioning.

The flocculant mixing system uses a jet agitator that employs high-speed hydraulic power to disperse chemical reagents or powder particles. This increases the fineness and enhances the contact and penetration area between the flocculant or powder particles and water, thereby shortening the dissolution time. The equipment consists of a three-tank overflow combination, namely preparation, maturation, and dosing tanks. It utilizes gravity and solubility to create a specific gravity difference in the solution, which automatically separates the dissolved and undissolved components. A low-speed stirrer is then used to further improve the uniformity of the solution.

The flocculant mixing system uses materials such as flocculated potassium permanganate, activated carbon, and other granular materials, powders, or concentrated liquids as raw materials. It continuously and automatically prepares solutions according to the required concentration and meteringly adds the prepared solution to the industrial process. The dry powder preparation and dosing device is widely used in water treatment, sewage treatment, and other process medium treatments in industries such as petroleum, chemicals, papermaking, electric power, coal, pharmaceuticals, and food.

Three-tank integrated continuous preparation, easy to operate and maintain.

Both dry powder and liquid polymer can be fed in double to meet different needs.

PLC fully automatic operation, saving labor.

The chemical reagent can be added by a screw pump or metering pump (the screw pump is typically used), with accurate and adjustable metering.

The equipment has no base and is fixed in place, with a beautiful appearance and easy maintenance.
