SUPRA-TDS™ Series Semi-Automatic Disc Filter
DIG introduces the innovative and patented SUPRA-TDS™ series, a semi-automatic disc filter that combines the benefits of disc element filtration with a user-friendly semi-automatic flushing operation to remove solids, debris, and other contaminants. This groundbreaking technology offers a cost-effective, efficient filtration solution with a simplified cleaning process—without the need to open the filter for manual cleaning or deal with the complexity of expensive fully automated systems..
Applications
- Agriculture, landscape irrigation, industrial processes, and aquaculture applications for maintaining water quality—particularly protecting drip emitters, micro sprinklers, and other sensitive applications.
- Supports secondary, backup filtration for gravel systems and sand separators.
Features
- TDS: Total Dissolved Solids, filtering the total concentration of dissolved inorganic salts and organic matter in water.
- Simple Operation: The cleaning process is quick and easy, requiring the opening of the flush valve at the filter bottom and a quarter turn of the overhead handle for 15–30 seconds.
- High Efficiency: Provides better protection by filtering smaller particles than semi-automatic screen filters of the same filtration grade.
- Small Footprint: Compact design fits a wide range of applications in various locations.
- Versatile Applications: Suitable for agriculture, landscape irrigation, and industrial use.
- Options: Clogging indicator allows for easy monitoring of filter head-loss conditions.
- Flow Rate Capability: Available in 2” and 3” sizes, with low friction loss and flow rates of up to 220 GPM (40 m³/h); higher flow rates can be achieved with battery set configurations of two to six units.
- Large Filtration Area: Achieves higher organic and inorganic contaminant holding capacity and lower flushing frequency.
- Construction: Made from polymeric materials with high resistance to corrosion and chemicals, and UV-protected for longer life.
