Water treatment dosing device

The scarcity of human water resources has promoted the development of water treatment technology, and the addition of chemicals is a commonly used technical measure in water treatment engineering. However, in many water treatment projects, outdated dosing equipment leads to tedious manual operations, waste of high-value chemical agents, and even affects the efficiency of enterprises.
In the process of water purification and wastewater treatment, various chemical agents (such as coagulants, coagulants, and defoamers) need to be added to achieve the treatment goal. Therefore, advanced dosing systems and dissolution equipment are important components in water treatment engineering.
In order to develop China's water treatment and environmental protection industry, Baoheng Pump Industry has developed and researched water treatment dosing devices such as coagulant (coagulant aid) dosing devices, corrosion inhibitor (scale inhibitor) dosing devices, pH adjustment acid (alkali) dosing devices, etc.

Performance characteristics

The dosage is precise and constant. Large dosing capacity and wide applicability. Easy to operate and manage. The dosage of the medication is easy to adjust.
Coagulant (coagulant aid) dosing device

principle

Natural water bodies contain a certain amount of colloidal particles, which can overcome the influence of gravity and maintain dynamic equilibrium under the action of electrostatic repulsion and Brownian thermal motion, without coagulation and precipitation, thereby affecting the turbidity index of water. The commonly used method for removing colloidal particles is to add highly charged ions or polymer substances to the water body, and use principles such as electrical neutralization, adsorption bridging, and net capture to destabilize the colloidal particles, condense and precipitate them, and clarify the water quality.
Common coagulants (coagulants) include aluminum salts, iron salts, and corresponding polymers.

Process Overview

This device mainly includes four parts: drug solution preparation system, metering and dosing system, safety system, and control system.
Solid drugs are added to the dissolving tank, and then mixed with industrial water in proportion to dissolve. They are then added to the dosing point through a metering system. The dosing control can be done manually or automatically based on the control signal output from the floating charge meter or the upper system.

scope of application

Municipal water supply, sewage treatment, pre-treatment of raw water for thermal power generation, and wastewater treatment.

Corrosion inhibitor (scale inhibitor) dosing device

principle

During natural operation, industrial circulating cooling systems tend to scale or corrode due to the combined effects of factors such as hardness, alkalinity, pH value, concentration ratio, temperature, and environmental humidity of the circulating water. Both can have adverse effects on the safety and operational efficiency of the circulating cooling system. In order to suppress scaling or corrosion, it is necessary to manually add corrosion inhibitors or scale inhibitors to the water. Common corrosion inhibitors and scale inhibitors include polyphosphates, zinc salts, polycarboxylates, phosphonates, and so on.

Solid drugs are added to the dissolving tank, and then mixed with industrial water in proportion to dissolve. They are then added to the dosing point through a metering system. The dosing control can be done manually or automatically based on the control signal output by the upper system.

scope of application

Thermal power generation or petrochemical cooling circulating water treatment.

Adjust pH value and add acid (alkali) device

principle

Due to the requirements of water treatment processes, the pH value of water often needs to be controlled within a certain range, and manually adding acid or alkali to the water is a direct and effective way to meet this requirement. Common acid and alkali neutralizing agents include sulfuric acid, hydrochloric acid, ammonia water, calcium hydroxide, sodium hydroxide, sodium carbonate, and so on.

Process Overview

This device mainly includes four parts: drug solution preparation system, metering and dosing system, safety system, and control system.
Solid drugs are added to the dissolving tank, then mixed with industrial water in proportion and dissolved, and added to the dosing point by the metering system; Liquid drugs are generally not diluted with water and can be added directly. The dosing control can be done manually or automatically based on the control signal output by the upper system.

scope of application

Thermal power generation or petrochemical cooling circulating water treatment, raw water pretreatment, wastewater neutralization treatment.
