Wastewater Treatment

SEQUOX® Biological Nutrient Removal Process

Cost Effective Nutrient Removal
The patented SEQUOX Nutrient Removal Process is the latest innovation for biological nutrient removal from wastewater. Even if nutrient removal is not the primary objective, the SEQUOX process results in sufficient process improvements and energy savings to make it cost effective.

Superior Effluent Quality
SEQUOX offers the benefits of sequencing aeration with the reliability of continuous clarification. Excellent denitrification occurs, and levels of 3 mg/l for Total N have been achieved. Although results depend upon BOD to Total P ratio, some plants have produced effluent values for P approaching 1 mg/l. To achieve better solids settling, SEQUOX incorporates a selector tank to provide a preconditioning of raw wastewater that inhibits filamentous growth. The process is energy efficient and has a small footprint, lowering capital costs.

High Flow Capability
Combining the SEQUOX Process with the ClarAtor Clarifier offers the ability to handle up to 4:1 sustained peak flows, resulting in additional treatment without additional costs. If infiltration and inflow is a problem, the SEQUOX-HF system offers superior treatment capabilities without exceeding effluent standards.

SEQUOX Process Advantages:

• Reduced energy requirement
• Biological nutrient removal
• Low levels of effluent N and P
• Selector tank promotes rapid settling
• Elimination of most chemical feed
• Batch reaction, continuous withdrawal
  
• Allows batch withdrawal for high flow
• Dedicated nitrification tank
• Sequencing without stopping blowers
• Simple operation, minimal valves
• No moving parts below water surface

ClarAtor®

Secondary Clarifiers Biological Wastewater Systems

Innovative High Performance Clarifier
The patented, low-maintenance, operator friendly ClarAtor provides clarification to the Aero-Mod System. It features no moving parts below the water, a uniform distribution and collection of the influent, and the unique ability to regulate the effluent flow rate. Its unique flow regulation system even provides in-basin surge storage.

Quality Fabrication
Stainless steel components, PVC piping, and aluminum handrails and walkways are easily installed into common-wall concrete tankage. This compact rectangular configuration reduces overall plant construction costs. The only operator attention typically required is periodic cleaning of the walkways and effluent discharge weirs. With no mechanical equipment below the water, mechanical maintenance is virtually eliminated.

ClarAtor Clarifier Advantages:

• No moving parts below water
• No motors, gears or electrical components
• Stainless steel fabrication
• No field welding or painting
• Minimal maintenance
• Rapid and positive sludge withdrawal
• Effluent flow regulation
• Applicable for a wide range of flows

TRITAN™ Belt Filter Press

With exclusive rights in the U.S. by Aero-Mod, the TRITAN™ belt filter press is a new design. The stainless steel TRITAN™ combines a sludge pre-thickener and a sludge press into one unit, eliminating the need for two separate pieces of equipment. It has three belt performances with single belt tracking. With few moving parts, the belt press design lends itself to minimal maintenance. It utilizes seamless belt technology for long life, while providing excellent dewatering and a dry cake equal to traditional equipment. The TRITAN™ produces a bio-solids cake with a solids concentration of 15% to 18% for aerobic sludge, and higher for anaerobic sludge. Three belt widths of 0.8, 1.2 and 1.5m are offered to meet your specific needs.

TRITAN Advantages:

• Simplicity
• Performance
• Stainless steel
• Compact design
• Packaged and integrated solution
• Pre-thickening
• Economical solution
