As environmental protection policies continue to tighten and the demand for water resource recycling becomes increasingly urgent, technological iteration and performance upgrades of water treatment equipment have become the core focus of high-quality development of the industry. in,Spinner filterWith core advantages such as high-precision filtration, low-energy operation, and compact footprint, it has quickly become the first choice equipment for municipal sewage treatment plant upgrading and renovation, industrial wastewater reuse, landscape water purification and other scenarios. It comprehensively solves the industry pain points of low efficiency, large footprint, and difficult maintenance of traditional filtration equipment, and helps water treatment projects achieve the dual goals of meeting emission standards and energy conservation and consumption reduction.
1. The core technical advantages of the rotary disk filter subvert the traditional filtration model
Compared with traditional sand filters, plate and frame filter presses and other equipment, the new generation fiber rotary disk filter relies on innovative structural design and high-quality filter material configuration to achieve a comprehensive upgrade in filtration performance. It has outstanding core advantages and fully meets the high efficiency, energy saving and intelligent needs of modern water treatment projects.
High filtration precision, stable and up to standard effluent water quality: The equipment uses special fiber filter cloth as the filter medium, with a filtration accuracy of up to 10-15 μm. The removal rate of suspended solids (SS) in sewage is as high as 90%. The effluent SS is stably controlled below 5 mg/L, easily meeting the Class A standard of the "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB18918-2002). It can also effectively remove some phosphorus, COD and other pollutants, laying a high-quality water quality foundation for reclaimed water reuse and river ecological water replenishment.
Small footprint, suitable for renovation and new construction projects: The vertical turntable modular design and fully immersed operation greatly increase the unit filtration area. Compared with traditional sand filters, it can save 75%-80% of the floor space. It is especially suitable for upgrading and renovation projects of old sewage treatment plants with limited land. It does not require large-scale expansion of civil engineering, and greatly reduces project investment and construction period.
Extremely low energy consumption and significantly reduced operating costs: The daily filtration process relies on gravity flow. Only the backwash and turntable driving links consume a small amount of electricity, with small water head loss and no additional power loss. At the same time, pulse backwash technology is used, which requires less water for backwash and does not require frequent replacement of filter materials. The long-term operating cost is much lower than that of traditional filtration equipment.
Fully automatic operation, easy post-maintenance: Equipped with an intelligent control system, it can automatically adjust the filtration cycle and backwash frequency according to the incoming water quality and volume, achieving 24-hour unattended operation; the filter cloth is highly durable, requiring only simple daily inspections, easy replacement and maintenance, low equipment wear rate, and an overall service life of more than 10 years, significantly reducing manpower and material investment in later operations and maintenance.
2. Full coverage of multiple scenes, and the turntable filter has a wide range of applications
With its flexible adaptability and stable performance, the rotating disk filter has been widely used in various major water treatment fields and has become the core equipment in the solid-liquid separation process. It covers multiple sectors such as municipal administration, industry, agriculture, and ecology, and has strong scene adaptability.
existMunicipal sewage treatmentIn the field of water treatment, as a depth filtration unit after secondary biochemical treatment, it effectively intercepts residual suspended solids and colloidal substances, helping sewage plants to quickly achieve upgrading and transformation to meet increasingly stringent environmental discharge requirements; inIndustrial wastewater treatmentIn the field of papermaking, textile, food, chemical industry, electric power and other industries, it can be used as a pre-protection unit for membrane treatment equipment such as ultrafiltration and reverse osmosis to intercept large particle impurities, extend the service life of membrane components, and at the same time realize the recycling of industrial wastewater and save fresh water resources;Ecological water treatmentIn the field, it is suitable for the circulation purification of landscape lakes, rivers, and rainwater storage tanks to enhance water transparency and improve the water ecological environment. In addition, it can also be used in aquaculture water purification, farmland irrigation water treatment and other scenarios, and the application boundaries continue to expand.
3. Industry development trend: Intelligent and modular turntable filter upgrade direction
As the water treatment industry transforms towards intelligence and intensification, rotating disk filter technology continues to be optimized and upgraded. At present, mainstream manufacturers have launched modular expansion models, which can flexibly increase the number of disks and modules according to the demand for water processing without redesigning civil engineering. They are also equipped with remote monitoring systems to achieve real-time upload of equipment operating data and remote fault warning, further improving equipment management efficiency. In the future, as environmental protection standards continue to be upgraded and water reuse rates continue to increase, rotating disk filters will rely on their core technological advantages to occupy the mainstream position in the water treatment and filtration equipment market and become an important support for the green development of the industry.
