Or-Tec's AlphaDisc for Municipal, Industrial & Food Processing Wastewater

The Or-Tec AlphaDisc is a high-performance stainless steel tertiary disc filter designed to improve wastewater effluent quality through the efficient removal of Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), and phosphorus. Utilizing woven 316 stainless steel filter media instead of traditional cloth media, the Or-Tec AlphaDisc provides durable, precision filtration with particle removal from 5 microns up to 200 microns, making it an excellent solution for municipal wastewater treatment plants, industrial wastewater systems, food and beverage processing facilities, and drinking water applications.

Unlike conventional cloth disc filters, Or-Tec's AlphaDisc features self-cleaning woven stainless steel filter media, automatic spray bar washing, low power consumption, and a compact modular design that minimizes maintenance while providing reliable long-term filtration performance.

• Or-Tec's Alphadisc is a stainless steel tertiary disc filter designed to remove Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), and phosphorus from wastewater.
• It utilizes woven 316 stainless steel filter media capable of filtering particles from 5 microns to 200 microns while providing long service life and dependable performance.
• The system is designed for municipal wastewater treatment plants, industrial wastewater treatment, food and beverage processing, and drinking water applications requiring high-quality tertiary filtration.

While both technologies provide tertiary filtration, stainless steel disc filters offer significant advantages in durability, maintenance, and long-term operating costs.

The Or-Tec AlphaDisc provides:

• Woven 316 stainless steel filter media, not traditional cloth filter media.
• Longer service life compared to traditional cloth filter media.
• Easier cleaning with an automatic spray bar system that tilts away for maintenance access.
• Consistent filtration performance without frequent media replacement.
• Improved equipment reliability.
• Well suited for demanding municipal and industrial wastewater applications where long service life is important.

The Or-Tec AlphaDisc is specifically designed to reduce Total Suspended Solids (TSS) and improve final effluent quality after secondary treatment.

Benefits include:

• Removes particles from 5 to 200 microns for exceptional polishing performance.
• Produces cleaner final effluent to help meet increasingly stringent discharge permits.
• Reduces BOD and phosphorus by capturing fine suspended solids.
• Self-cleaning stainless steel filter media minimizes operator intervention.
• Handles Flows Exceeding 6.8 Million Gallons Per Day Per Unit, making it suitable for both new and expanding wastewater treatment plants.

• The Or-Tec Alphadisc filters particles ranging from 5 microns up to 200 microns.
• This fine filtration capability makes it highly effective for tertiary wastewater treatment where removal of small suspended solids is necessary to improve final effluent quality.
• The precision woven stainless steel media provides consistent filtration across the entire operating range.

• The Or-Tec Alphadisc is designed with a self-cleaning automatic spray bar system that continuously cleans the stainless steel filter media during operation.
• The spray bar assembly can tilt 90 degrees away from the filter discs, allowing operators easy access for inspection and maintenance.
• Combined with durable stainless steel filter media and low power requirements, the system helps reduce operating costs and downtime.

Adding tertiary disc filtration is one of the most cost-effective ways to improve wastewater effluent quality without major plant expansion.

The Or-Tec AlphaDisc helps by:

• Providing high-capacity tertiary filtration in a compact modular footprint.
• Installing in-channel or in-tank to fit existing plant layouts.
• Increasing solids removal efficiency without adding large clarification basins.
• Supporting permit compliance by lowering TSS, BOD, and phosphorus in the final effluent.
• Reducing operating costs through low power consumption, automatic self-cleaning, and minimal maintenance requirements.

• The AlphaDisc is available for in-channel and in-tank installations.
• Its compact modular design allows the equipment to be incorporated into new wastewater treatment facilities or retrofit projects where installation space is limited.
• Multiple disc configurations are also available to accommodate larger treatment capacities.

The Alphadisc is designed for a wide variety of water and wastewater treatment applications.

Typical installations include:

• Municipal wastewater treatment plants
• Industrial wastewater treatment
• Food and beverage processing
• Paper mills
• Steel manufacturing
• Drinking water treatment facilities

It's durable stainless steel construction makes it suitable for demanding operating environments across multiple industries.

• Many wastewater treatment facilities choose Or-Tec's Alphadisc because it combines fine tertiary filtration, woven stainless steel filter media, automatic self-cleaning, low power consumption, and high hydraulic capacity in a compact system.
• The ability to remove TSS, BOD, and phosphorus while filtering particles as small as 5 microns makes it an effective tertiary polishing solution.
• Its stainless steel filter media offers durability and long-term reliability for municipal and industrial wastewater treatment applications.

The Or-Tec Alphadisc is used in numerous filtration applications, including:

• Municipal wastewater treatment plants
