When dosing
polyaluminium chloride, many operators utilise specialised dosing equipment for this purpose. Why choose dosing equipment specifically for polyaluminium chloride?
This is primarily because employing such dosing equipment enables effective cost savings. The use of dosing apparatus allows for more precise determination of dosage and volume, thereby reducing material expenditure. Furthermore, it facilitates a more thorough reaction between the polyaluminium chloride and the wastewater. Given the extensive applications of polyaluminium chloride Its role is particularly significant and evident across diverse sectors such as water supply treatment, power generation, oil fields, textile dyeing, papermaking, and pharmaceutical industries. Consequently, the precision of polyaluminium chloride dosage is an essential consideration in water treatment processes. However, while traditional manual dosing methods for polyaluminium chloride products are straightforward, achieving precise dosage is challenging. This necessitates specialised polyaluminium chloride dosing equipment to guarantee precise chemical delivery. Dosing systems for polyaluminium chloride products can be customised to meet diverse operational requirements. To ensure the longevity of polyaluminium chloride dosing equipment, thorough preparatory measures must be undertaken prior to use.
What should be noted when operating polyaluminium chloride dosing equipment? First, activate the disinfection tank pump and open the dosing chamber water supply. At this stage, set the solution tank's solenoid valve to automatic mode and press the inlet valve button to initiate water filling. Cease water supply once the solution tank reaches the preset water level. Subsequently, proceed with the addition, dissolution, and utilisation of the polyaluminium chloride. As this compound is water-soluble and possesses certain corrosive properties, preliminary testing based on the raw water quality should be conducted prior to dosing to determine the optimal dosage. For convenient dosage calculation, a polyaluminium chloride solution concentration of 2% to 5% is generally recommended. This means that when preparing the polyaluminium chloride solution, it can be mixed and dissolved initially at a ratio of approximately 1 part polyaluminium chloride to 5 parts clean water, before adding further water to dilute it. It is important to note that thorough stirring must be maintained throughout the solution preparation process. This prevents uneven dilution of the chemical, which could cause sedimentation, block equipment pipelines, and adversely affect water treatment efficacy. To ensure consistent chemical concentration, no additional water should be added to the solution once it has been prepared.
