Currently, the standard upgrading and renovation work of sewage treatment plants across the country is in full progress, and industrial wastewater reuse policies continue to be implemented. The water treatment industry has a surge in demand for efficient, energy-saving, and easy-to-maintain filtration equipment.fiber turntable filterAs a core equipment specially developed for the advanced treatment of sewage, with its differentiated performance advantages, it has become the core selection for the standard upgrading and transformation of various water treatment projects. It not only effectively solves the problem of water quality standards, but also helps project parties control investment and operating costs, achieving a win-win situation of environmental protection and economic benefits.
1. Why is the turntable filter preferred for sewage improvement and transformation?
Upgrading old sewage treatment plants and optimizing industrial wastewater treatment systems often face multiple problems such as insufficient land space, excessive energy consumption, and complex operation and maintenance. Traditional filtration equipment is difficult to adapt to the needs of transformation. However, from design to performance, the rotary disk filter fully meets the core demands of the standard improvement and transformation scenario, and has become the industry-recognized preferred equipment.
on the one hand,Low civil investment and short construction period. The turntable filter is an integrated device and is easy to install on site. There is no need to build a large filter tank and it can be directly connected to the existing water treatment process. For the renovation of old projects, there is no need to dismantle the original facilities on a large scale, greatly shortening the construction period and reducing losses caused by project shutdowns; on the other hand,Resistant to water quality fluctuations and strong operational stability. In the face of sudden fluctuations in incoming water volume and water quality, the equipment can quickly adjust operating parameters, always maintain a stable filtration effect, avoid the risk of excessive effluent water quality, and adapt to complex and changeable sewage treatment scenarios.
2. Compared with traditional equipment, the core advantages of turntable filters are clear at a glance
Compare items | Spinner filter | Traditional sand filter | Ordinary filter press equipment |
|---|
Covered area | Very small, 1/5-1/4 of the sand filter | Covers a large area and requires large-scale civil construction | Medium, with many supporting facilities |
Operating energy consumption | Extremely low, gravity filtration, low backwash energy consumption | High energy consumption, requiring continuous operation of pressurized pumps | High energy consumption and high loss of pressurized equipment |
Effluent water quality | SS≤5mg/L, stable and up to grade A | Water quality fluctuates greatly and accuracy is low | The effluent contains impurities and requires secondary treatment. |
Operation and maintenance costs | Fully automatic operation, simple maintenance, and durable filter cloth | The filter material needs to be replaced regularly, making operation and maintenance cumbersome. | Easy to wear and tear, frequent parts replacement, high labor costs |
3. Practical case: Rotary disk filter helps sewage plant standard improvement and efficient implementation
Rotary disk filters have played a key role in the standard improvement and renovation projects of municipal sewage treatment plants in many places in China. The original treatment process effluent of a county-level municipal sewage treatment plant only met Grade 1B standards and needed to be upgraded to Grade 1A standards. The project used a fiber turntable filter as an advanced treatment unit. After the transformation, the effluent SS was stably controlled below 4mg/L, fully meeting the Grade 1A emission standards. At the same time, the equipment occupied only 20% of the original sand filter, the operating energy consumption was reduced by 60%, and the operation and maintenance personnel were reduced by 70%. The transformation and commissioning was completed in just 30 days, and the environmental protection acceptance was successfully passed.
In the industrial field, after a paper mill wastewater reuse project was installed with a turntable filter, the wastewater reuse rate increased from 65% to 90%, saving more than 100,000 tons of fresh water every year, while avoiding the risk of excessive wastewater discharge, significantly reducing the risk of environmental penalties, and achieving a double breakthrough in resource recycling and cost control.
4. Key points when choosing a turntable filter
For engineering purchasers and project leaders, there are three core elements to focus on when purchasing turntable filters: First,Filter cloth material, give priority to polyester fiber or stainless steel filter cloth that is corrosion-resistant, high-strength, and easy to backwash to ensure filtration accuracy and service life; secondly,Intelligent configuration, choose equipment with automatic backwashing, water quality monitoring, and fault warning functions to reduce manual intervention; thirdly,Manufacturer strength, choose a regular manufacturer with integrated R&D, production, installation, and after-sales services to ensure equipment quality and later operation and maintenance support.
