Application of SCM530 Flow Cytometer in Chemical Addition Process of Power Plant Water Treatment
Application of SCM530 Flow Cytometer in Chemical Addition Process of Power Plant Water Treatment
In the energy heart of power plants, water serves as the lifeblood sustaining their vigorous operation. Every drop, from cooling cycles to boiler steam, undergoes meticulous treatment. At the first checkpoint of water treatment—the pretreatment stage—a cutting-edge technology called the Flow Cytometer (SCD) is quietly revolutionizing traditional chemical dosing methods, becoming the intelligent brain that optimizes water conservation, reduces consumption, and enhances efficiency in power plants.
- What is the streaming current meter?
Simply put, the flow current meter is like a highly sensitive "charge detector" that can detect the strength of the charge carried by tiny colloidal particles in water in real time.
At its core is a detection cell with a piston. As the water sample flows through, the piston moves back and forth, pushing charged particles in the water and generating a weak electrical current signal. The instrument captures and amplifies this signal and converts it into a clear reading (SC value).
It directly reflects the core principle of coagulation treatment-the effect of electro-neutralization.
- Why is it indispensable in power plant water treatment?
The water treatment system of power plants is huge and complex. The primary task is to convert raw water from rivers and lakes into clear water. If the pretreatment effect is poor, suspended solids and colloids will quickly pollute and block the subsequent expensive reverse osmosis membranes and ion exchange resins, resulting in reduced water production efficiency, frequent cleaning and soaring operating costs.
Traditional coagulant dosing depends on the experience of the master, or manual adjustment according to the turbidity of the raw water, which has serious lag and blindness. When the water quality fluctuates, either the dosage is insufficient to cause the discharge water to be unqualified, or the dosage is excessive to cause waste and the amount of sludge increases.
The advent of the current flow meter revolutionized this field, transforming the coagulation process from an "experience-driven" to a "data-driven" automated control system.
3. How does it work? -Intelligent Coagulation "Autonomous Driving"
Imagine the self-driving function of a car, and the flow current meter is the "self-driving system" for water treatment.
Set a target: The engineer sets a baseline value (determined by the beaker test).
Real-time monitoring: The instrument continuously monitors the charge of the water sample after coagulant treatment.
Automatic decision: When the turbidity or colloidal concentration of raw water changes, the flow current deviates from the set value. The SCM530 flow current meter automatically adjusts the frequency of the dosing pump to increase or decrease the dosage of the reagent, so that the flow current returns to the target range.
Cycle: This process is carried out every second to form a dynamic and real-time closed-loop control system, which can automatically stabilize the coagulation state at the optimal point no matter how the water quality of raw water fluctuates.
- What are the huge benefits it brings to the power plant?
1. Stabilize effluent and protect core equipment: It can ensure that the turbidity of pretreatment effluent remains at a low level (such as <1NTU), protect the downstream reverse osmosis membrane and ion exchange resin from the source, extend their life by more than 30%, and greatly reduce the number of cleaning and downtime.
2. Precise dosing for significant chemical savings: Move beyond "extensive" dosing methods and apply chemicals precisely based on actual needs. Statistics show this approach can reduce coagulant usage by 15% -30%, delivering remarkable economic benefits.
3. Reduce sludge and reduce disposal costs: the dosage of medicine is reduced, and the amount of chemical sludge produced is naturally reduced, saving sludge treatment costs, and more environmentally friendly.
4. Full automation, liberating labor force: It realizes 7x24 hours of unmanned automatic operation, reduces the dependence on the experience of operators, and improves the overall automation level of the power plant.
In the era of intelligent and refined operations, compact devices like flow current meters serve as vital tools for power plants to enhance water treatment efficiency and achieve energy conservation and carbon reduction goals. Though discreetly installed along pipelines, these instruments quietly function as the "brain" of the system, safeguarding the plant's water supply lifeline while generating tangible economic and environmental benefits for enterprises.
