Used ALAR AV360 Industrial Wastewater Filter System

MANUFACTURER INFORMATION

ALAR Engineering develops industrial wastewater treatment and sludge-dewatering systems. Its Auto-Vac line uses rotary vacuum drum precoat filtration to draw liquid through filter-aid media while retaining and dewatering suspended solids. ALAR describes the Auto-Vac as using a non-segmented drum, precoat microfiltration, and incremental removal of spent media and collected solids to maintain filtration performance.

MAIN PRODUCT DESCRIPTION

Used ALAR Engineering Auto-Vac Model 360 skid-mounted rotary vacuum drum precoat filter designed for industrial wastewater treatment, effluent clarification, and sludge dewatering. The system features a stainless steel drum measuring approximately 3 feet in diameter by 6 feet long, with a nominal filtration area of approximately 56.5 sq. ft. The listing states a total connected load of approximately 20 HP and includes two 3,000-gallon holding tanks, a two-stage pump, and a spare pump. The main system has an approximate footprint of 9 feet wide by 16 feet 8 inches long, a maximum height of approximately 8 feet 6 inches, and an approximate shipping weight of 6,200 pounds. The unit was last used to treat wastewater from an automobile remanufacturing facility. Serial number requires confirmation because the description and specification table show different numbers. Aaron Equipment stock number 54550001.

APPLICATIONS

• Industrial wastewater treatment
• Sludge dewatering
• Suspended-solids removal
• Fine-particle filtration
• Effluent clarification
• Process-water recovery
• Automotive remanufacturing wastewater
• Metal-finishing wastewater treatment
• Paint and coating wastewater
• Pigment removal
• Chemical process wastewater
• Concrete and mineral fines removal
• Food-processing wastewater
• Oil, grease, and emulsified-solids treatment after proper pretreatment
• Reduction of liquid waste volume before disposal

ALAR identifies the Auto-Vac product line for industrial wastewater containing fine suspended solids, precipitated metals, pigments, oils, grease, and other difficult-to-settle contaminants. Actual suitability depends on pretreatment chemistry and the characteristics of the individual waste stream.

SUITABLE PRODUCTS AND MATERIALS

• Chemically treated industrial wastewater
• Automotive process wastewater
• Metal-finishing rinse water
• Precipitated metal solids
• Paint and coating wastewater
• Pigment-bearing wastewater
• Concrete wash water
• Mineral fines
• Suspended inorganic solids
• Industrial wash water
• De-emulsified fats, oils, and grease
• Chemical sludge
• Filterable process solids
• High-solids wastewater
• Other pretreated industrial liquid waste streams

Actual process suitability should be determined using wastewater flow rate, solids concentration, particle size, pH, temperature, oil content, chemical composition, filter-aid selection, desired filtrate quality, and disposal requirements.

FAQS

• WHAT TYPE OF FILTER IS THIS?
  This is an ALAR Auto-Vac rotary vacuum drum precoat filter designed for industrial wastewater filtration, solids separation, and sludge dewatering.
• WHAT IS THE MODEL NUMBER?
  The Aaron Equipment listing identifies the unit as Model 360. ALAR has also used the AV360 designation for equipment of this size, so the nameplate should be checked to confirm the full model.
• WHAT SIZE IS THE FILTER DRUM?
  The listed stainless steel drum is approximately 3 feet in diameter by 6 feet long.
• WHAT IS THE FILTRATION AREA?
  The listing states a nominal filtration area of approximately 56.5 sq. ft.
• WHAT PARTICLE SIZE CAN THE FILTER CAPTURE?
  The listing states approximately 0.5 to 1 micron. Actual capture performance depends on the filter-aid grade, precoat depth, wastewater chemistry, particle characteristics, vacuum level, and operating conditions.
• HOW DOES AN AUTO-VAC FILTER WORK?
  Vacuum draws liquid through a precoat filtration layer on the rotating drum while solids remain on the filter surface. ALAR describes the system as incrementally removing the collected solids and a thin layer of spent media to expose fresh filtration media.
• WHAT ARE THE SYSTEM DIMENSIONS?
  The listed maximum height is approximately 8 feet 6 inches, and the stated skid footprint is approximately 9 feet wide by 16 feet 8 inches long. Buyers should confirm whether these measurements include the tanks and pumps.
• HOW MUCH DOES THE EQUIPMENT WEIGH?
  The listing states an approximate shipping weight of 6,200 pounds. Separate tank and accessory weights are not provided.
• WHAT WAS THE SYSTEM PREVIOUSLY USED FOR?
  It was last used to treat wastewater from an automobile remanufacturing facility.
• WHAT IS THE CORRECT SERIAL NUMBER?
  Serial No. 12895.
• CAN AARON EQUIPMENT HELP DETERMINE WHETHER THIS FILTER FITS MY WASTEWATER APPLICATION?
  Yes. Provide the wastewater source, daily volume, flow rate, solids percentage, particle size, pH, temperature, oil content, chemical analysis, pretreatment process, discharge requirements, and desired hours of operation so the Aaron Equipment team can help assess the application.
• CAN THE FILTER SYSTEM BE INSPECTED BEFORE PURCHASE?
  Contact Aaron Equipment to discuss an inspection, additional photographs, nameplate verification, equipment documentation, included components, and testing availability.
• DOES AARON EQUIPMENT HELP WITH SHIPPING?
  Yes. Aaron Equipment can assist with loading and freight coordination. Buyers should confirm whether the main skid, two holding tanks, two-stage pump, and spare pump require separate loads and obtain exact shipping dimensions and weights for each component.
