Flot-Star™ Dissolved Air Flotation (DAF) Wastewater Treatment System
The ALAR® MicroRise™ — formerly known as the Flot-Star™ — Rectangular Dissolved Air Flotation (DAF) system is a reliable and efficient solution for wastewater treatment. Alar’s rectangular DAF addresses common wastewater challenges such as downstream bottlenecks and equipment headaches by offering upgraded bubble generation, enhanced hydraulic and solids loading rates, and exceptional separation of suspended solids. This results in significant reduction of total suspended solids (TSS), fats, oils, and grease (FOG) and insoluble biological oxygen demand (BOD).
The Flot-Star Dissolved Air Flotation system utilizes micro-bubbles to effectively separate insoluble materials like total suspended solids (TSS), BOD, and FOG from wastewater. By dissolving gas in the solution, the DAF system creates micro-bubbles that capture and lift wastewater particles to the surface for removal. This dissolved air flotation process is particularly suitable for industries with low-density solids that cannot be effectively treated using settling systems or other methods.
Designed for optimum throughput within a small footprint, the Flōt-Star Rectangular Dissolved Air Flotation system offers a cost-effective and sustainable solution for various wastewater applications. The Alar DAF technology achieves efficient solids separation by utilizing pretreatment chemicals such as coagulant and flocculent polymers, which concentrate buoyant materials.
With Alar’s stock air dissolution pumps and [optional] inclined plate packs, the Flot-Star Rectangular DAF provides increased solids loading and volume capacity. This ensures efficient and reliable operation, making our Rectangular Dissolved Air Flotation equipment ideal for industrial wastewater treatment.
Industry Solutions
Using pretreatment chemicals for solids separation, such as coagulant and flocculent polymers, is often a necessary step prior to feeding wastewater to the DAF chemical addition system. These polymers break apart the emulsified solids from the water and allow them to concentrate into a buoyant material.
A Dissolved Air Flotation System is a cost effective and sustainable process for handling a variety of wastewater applications. The Flot-Star DAF air dissolution pumps provide an upgrade in bubble generation, enhanced hydraulic and solids loading rates, exceptional separation of suspended solids, and significant FOG reduction. The Alar DAF float handling technology can also be used as BOD treatment equipment. Our high-quality Flot-Star™ DAF systems provide many unique advantages detailed below and in the downloadble borchure found in resources:
The Alar ® Flot-Star™ Rectangular DAF System Advantages
OVIVO ® | Alar ® is a trusted provider of high-quality Rectangular Dissolved Air Flotation equipment that features a combination of robust construction, innovative design, and sustainability.
Durable Construction: The Alar ® Flot-Star™ is fully constructed with 304 stainless for corrosion resistance
Easy Installation: A pre-piped, pre-wired, and skid-mounted DAF System ensures a quick setup and reduces downtime
Energy Efficient: Alar Stock Air Dissolving Pumps (ADP) for DAF recycling are designed for high efficiency and low wear; ADP generates 30-micron bubbles and is capable of pumping liquid and gas without cavitation, saving up to 40% of power usage compared to conventional Dissolved Air Flotation systems
Sustainabile & Low Maintenance: The all electric rectangular DAF operation of the Flot-Star™ eliminates the need for pneumatic parts or air compressors; simplifying maintenance, reducing operational complexity and power consumption
Advanced Separation Technology: Utilizes micro-bubbles to lift and separate TSS, FOG, and BOD
Compact Design: Without the need for a rentention tank the Alar ® Flot-Star™ DAF System is able to fit in small spaces while providing optimal throughput for industrial wastewater treatment; reducing the overall DAF footprint and resource usuage, making it environmentally friendly
Chemical Pretreatment Integration: Uses coagulants and flocculants for enhanced separation
Increased Capacity: Alar Stock Air Dissolving Pumps (ADP) and optional inclined plate packs generate improved solids handling.
Even Flow Distribution: The DAF Inlet Box incorporated into the Alar ® Flot-Star™ Rectangular DAF System ensures an even flow distribution across the flotation area, optimizing performance
Prevents Buildup: The enhanced process of the Alar ® Flot-Star™ incorporates flush nozzles at the base of the Dissolved Air Flotation Tank preventing solids buildup over time
Flot-StarPLUS™:
Like the original Flot-Star™ system, the Flot-StarPLUS™ utilizes a DAF equalization process to remove solids from water. The Flot-StarPLUS also works like the original dissolved air floatation system by producing a stream of micro-bubbles that float solids to the surface which are removed by a scraping mechanism. The Flot-StarPLUS is equipped with the stock air dissolution pumps plus inclined plate packs. This ADP and plate pack combination allows for increased solids loading or volume capacity.
Flot-StarMAX™:
The Flot-StarMAX™ follows the same Alar DAF design principles as the others, with maximum results. Instead of dissolving a gas in solution through a dissolution process, the Flot-StarMAX generates micro-bubbles using charged surfactants or colloidal gas aphrons through a gas entrainment process. The benefit of CGA entrainment is that it can process greater hydraulic rates and solids loadings with less components and a smaller footprint than conventional dissolved air floatation equipment.
