Aqualitec Corp.
About
Aqualitec Corp. is a Los Angeles, California-based manufacturer of wastewater headworks screening equipment, sludge dewatering and thickening systems, and dissolved air flotation units with over 35 years of experience and more than 11,000 installations across 95 countries. The company entered the US market in 2009 and has since completed approximately 150 domestic installations. Aqualitec's core design philosophy centers on mechanical simplicity and retrofit-friendly engineering — equipment is designed to fit into existing channel structures without requiring costly civil modifications, minimizing installation expense and facility downtime. The screening product line includes the Screentec vertical bar screen available in four capacities from 0.01 MGD to over 30 MGD, the Raketec multi-rake bar screen with no moving components below grade, the Drumtec rotary drum screen with internal spray cleaning, the Spiraltec combined screw screen and conveyor, the Compactec washer-compactor, the Washtec wash press, and the Grittec grit classifier. Sludge treatment equipment spans the Omega belt filter press, gravity belt thickener, combined 3-belt press and thickener, decanter centrifuge, and screw press. Dissolved air flotation is addressed by four model families — Altec, Deltec, Gamtec, and Sigtec — covering a range of flow rates and solids loading conditions for municipal and industrial wastewater applications. Documented field results include an installation in Mendocino, California requiring only $800 in maintenance over ten years and a Ukiah, California plant saving $500,000 per year in pump maintenance costs.
Key Products
Mechanically cleaned vertical bar screen that removes coarse solids and debris from raw wastewater influent at headworks inlet channels to protect downstream treatment equipment.
Multiple-rake bar screen with no moving mechanical components located below channel grade level, allowing routine maintenance from the operating floor while continuously screening influent flow.
Rotating cylindrical drum screen that filters fine solids and screenings from wastewater flows, with continuous internal spray cleaning for consistent capture efficiency.
Combined screw screen and conveyor system that screens, washes, dewaters, and conveys captured solids in a single compact unit for headworks space-constrained installations.
Integrated unit that receives screenings from bar screens, washes them to remove organics and odor-generating material, dewaters the washed solids, and compresses them into a compact discharge for reduced hauling volume.
Dedicated screenings wash and dewatering press that cleans and compacts bar screen debris to reduce putrescibility and moisture content prior to disposal.
Grit washing and classification unit that separates inorganic sand and grit from organic material in grit slurry, producing a clean grit fraction for disposal and returning organics to the treatment process.
Gravity drainage and mechanically pressed sludge dewatering system that applies progressive belt compression to thicken and dewater digested or raw wastewater sludge into a manageable cake for disposal or beneficial reuse.
Porous belt unit that thickens liquid sludge by gravity drainage prior to mechanical dewatering, reducing the volume fed to downstream belt filter presses or centrifuges and improving overall dewatering efficiency.
Combined gravity thickening and belt press dewatering unit that performs both thickening and pressing stages on a single machine to achieve high cake dryness in a compact footprint.
High-speed rotating bowl centrifuge that uses centrifugal force to separate and continuously discharge dewatered sludge cake from liquid centrate, achieving high throughput and dry cake solids content.
Low-speed rotating screw dewatering system that progressively compresses sludge in a tapered screen cylinder to extract water, producing a dry cake discharge with low energy consumption and minimal operator attention.
Dissolved air flotation system that uses micro-bubble aeration to float and skim suspended solids, fats, oils, and greases from municipal or industrial wastewater streams in a compact footprint.
Dissolved air flotation unit configured for moderate flow rate applications combining efficient micro-bubble generation with a sloped plate separation zone for enhanced solids capture.
Dissolved air flotation system designed for higher flow rates and greater solids loading, used in primary clarification, secondary clarification bypass, and industrial pretreatment applications.
High-performance dissolved air flotation unit for demanding municipal and industrial wastewater applications requiring maximum hydraulic and solids loading capacity with reliable automated operation.
