The Parkson DynaFilter® ’s innovative design and continuous self-cleaning operation make it an ideal choice for achieving high-efficiency filtration with minimal maintenance. Its ability to provide consistent, high-quality effluent ensures reliable performance in a variety of wastewater treatment applications.
Principle of Operation
The DynaFilter® is a continuous upflow, deep bed, granular media filter. It is designed to provide high-quality filtration with minimal operator intervention, ensuring consistent performance in a variety of wastewater treatment applications. Here’s how the DynaFilter® operates:
Key Steps
Influent Entry and Initial Filtration
- The influent wastewater enters the filter through an influent pipe located at the bottom of the filter unit.
- The wastewater is distributed evenly across the bottom of the sand bed, ensuring uniform flow and maximizing the filter’s effectiveness.
Upflow Filtration
- The wastewater flows upwards through the sand bed, passing through the granular media where particulate matter and impurities are trapped.
- The clean, filtered water rises to the top of the filter unit and is collected in the effluent launder for discharge or further treatment.
Continuous Sand Cleaning and Recycling
- The key feature of the DynaSand® Filter is its continuous self-cleaning mechanism. As filtration occurs, dirty sand (laden with captured particulates) is drawn from the bottom of the sand bed into an airlift pump.
- The airlift pump conveys the dirty sand to the sand washer located at the top of the filter.
- In the sand washer, the dirty sand is cleaned by a countercurrent flow of water. The heavier sand particles settle back into the sand bed, while the lighter contaminants are carried away by the wash water and removed from the system.
Effluent Discharge
- The filtered water, now free from particulate matter and impurities, exits the filter through the effluent launder.
DynaFilter® EcoWash®
Key Feature
- Intermittent Sand Washing
The DynaFilter® EcoWash® is an enhanced version of the original DynaFilter®, specifically engineered to reduce energy consumption and operational costs through its innovative intermittent sand washing system. This filter combines the proven continuous upflow filtration technology with energy-saving features, ensuring optimal performance and sustainability.
DynaFilter® D2
Key Features
- Dual Media Filtration
- Superior Contaminant Removal
The DynaFilter® D2 is an enhanced version of the original DynaFilter®, incorporating dual media technology to provide higher filtration efficiency and improved water quality. This filter is specifically engineered for applications that demand high purity water, such as potable water production, ultrapure water for industrial processes, and advanced wastewater treatment.With its proven reliability and ability to meet stringent effluent quality standards, the DynaFilter® is an ideal solution for facilities seeking enhanced contaminant removal and operational efficiency.
Denite Filter®
Key Features
- Integrated Denitrification and Filtration
- The combined process reduces the footprint required for treatment, making it suitable for facilities with limited space.
The DynaFilter® Denite® integrates biological denitrification with continuous sand filtration, providing a compact and efficient solution for nitrogen removal. This filter is engineered to meet stringent nutrient removal requirements, ensuring compliance with regulatory standards for discharges into sensitive water bodies.
Features and Benefits
Consistent Filtration Quality
The continuous upflow design ensures steady removal of particulates, providing consistently high-quality effluent.
No Need for Backwashing
Unlike Rapid Gravity Filters and Multimedia Pressurized Sand Filters, the DynaSand® Filter does not require periodic backwashing, which reduces operational interruptions and maintenance efforts.
Uninterrupted Operation
The self-cleaning system allows for continuous filtration, ensuring a constant supply of treated water without the need for shutdowns for cleaning.
Lower Operational Costs
Reduced energy consumption translates into lower operational costs compared to the energy-intensive backwashing processes required by Rapid Gravity Filters and Multimedia Pressurized Sand Filters.
Environmental Sustainability
The energy-efficient design contributes to the sustainability goals of the facility, reducing its overall environmental impact.
Superior Water Quality
The fine sand media provides excellent removal of suspended solids, resulting in superior water clarity and quality.
Versatility
The high filtration efficiency makes the DynaSand® Filter suitable for a wide range of applications, including municipal, industrial, and process water treatment.
Minimal moving parts and a robust self-cleaning mechanism
The DynaSand® Filter requires less maintenance compared to other filtration systems.
Reduced Downtime
The low maintenance requirements minimize operational downtime, ensuring continuous and reliable performance.
Cost Savings
Lower maintenance needs result in cost savings over the lifespan of the filter, making it an economically attractive option.
