AST BEAD FILTER SOLUTIONS

AST Bead filter Solutions from Aquaculture Systems Technologies have long been the pioneers in bead filter design and construction, bringing you the Bubble Bead filter, Propeller Washed Bead filter, and the Polygeyser.

They have recently been working on a recirculating Polygeyser for high BOD and high waste loads for treatment of effluent and wastewater. AST now offers wastewater treatment filter and services and together with Pure Aquaculture we can offer you complete solutions for all of your aquaculture and wastewater needs.

Project:

Pilot RCPG System for Facultative Lagoon Polishing

Applications:

• Municipal and Industrial Wastewater
• High Strength Waste
• Pristine Polishing

Problem:

Recently, rural and decentralized wastewater treatment systems discharge standards have been tightened to the point that the traditional treatment methods are being found to be inadequate. These systems, such as facultative lagoons, are being required to meet strict BOD and Ammonia standards. This push for cleaner discharges is pushing these municipalities to either implement tertiary polishing systems or upgrade to expensive mechanical plants, which many small communities cannot afford.

PROBLEM:
AST Case Study
PELAHATCHIE FACULTATIVE
LAGOON POLISHING

AST provided a trailer mounted pilot scale test unit to pull a side stream off of the current waste stream. This pilot system included one 10 ft3 Recirculating PolyGeyser® (RCPG) unit, a 1 hp regenerative blower, and a linear air pump. The RCPG 10 is run completely pneumatically. It contains a 10ft3 packed bed of Enhanced Nitrification (EN) media that provides solids capturing and biological filtration. The unit ran for 6 months while data was collected for BOD and ammonia influent and effluent concentrations.

SOLUTION:

• High efficiency
• Low O&M
• Automated Non-Mechanical Backwash
• Simultaneous Mechanical & Biological Filtration
SYSTEM BENEFITS: • Municipal & Industrial Wastewater
• High Strength Waste
• Pristine polishing

10 ft3 Recirculating PolyGeyser unit, 1 hp regenerative blower, and linear air pump. Project: Pilot RCPG System for Facultative Lagoon Polishing

RESULTS:

AST’s RCPG lines of filters are very efficient at mechanically and biologically filtering a wide variety of waste streams. The Pelahatchie waste stream was an excellent test of the unit’s ability to consistently produce the stringent effluent quality waters that are becoming more common across the rural United States. The filter continued to produce dischargeable quality effluents throughout the 6 month test period.

Currently plans are moving forward to implement the full scale design for this system.
