Dewater For Pennies Per Gallon with an ALAR Auto-Vac Sludge Dewatering System

Got Sludge? Then you need the the Alar  Auto-Vac Sludge Dewatering System.  Alar’s patented filtration works great with DAF systems and replaces conventional centrifuges, filter press and belt press technologies.

The Auto-Vac generated landfill ready solids that are often used as compost or spread on fields.  The clean filtrate water can be discharged into the city sewer or in some cases, used for irrigation.

The ALAR Auto-Vac pulls instead of presses the liquid, leaving the solids suspended on the top of the drum. As the drum rotates an advanced knife blade slices the solids off the drum…leaving a clean surface with every rotation.

The Auto-Vac requires approximately 30 minutes to start and 30 minutes to clean.  No breaking of plates or labor is needed.  An operator simply starts the machine and spends the remaining shift work on production for the company. The dry solids come off the Auto-Vac about 2 to 3 times drier than the filter press.  When paying for hauling, this will save dollars in the long run; the wetter the solids-the more the more hauling weight.Auto-Vac Rotary Vacum Drum Precoat Filter


With over 2,000 installations worldwide, ALAR is confident that the Auto-Vac will exceed your expectations.  ALAR manufacturers 16 filter sizes that can handle low or high volumes.

Industries Served:  Commercial Bakeries – Snack Food – Dairy – Meat Packaging – Slaughter Houses – Candy – Wineries – Fisheries – Beer

ALAR Water Recycling Systems

ALAR Auto-Vac C-Series Filter

ALAR Auto-Vac C-Series Filter

ALAR Water Recycling Systems will be at the World of Concrete Show this week at the Las Vegas Convention Center.   ALAR’s Booth No. N253 will have a working model of the Auto-Vac on display.

The photo in this post is the Auto-Vac C Series Water Recycling/Cement Dewatering Filter.  It is a self-cleaning filter that dewaters cement fines and yields nearly ASTM C-94 grade batch water.  Processed water can be recycled back into the batch without influencing set times and finishing.  It has redefined wastewater filtration in the concrete industry.  It is the only water recycling system that is  self-cleaning filter (non-clogging) on the market that filters cement fines and pigment color out of concrete process (gray water); yielding clear recyclable water and dry manageable solids.

The Auto-Vac is the mechanical alternative to conventional weir systems and dredging operations used by precast and ready mix producers dealing with high return rates, color, and high strength concrete.

Excellent for Concrete Operations Including but Not Limited To:

  • Ready Mixed
  • Precast
  • Color/Iron Oxide Pigments
  • Sawing/Grinding/Grooving/Polishing/Drilling
  • Roofing & Concrete Tile

This photo was taken at Spragues’ Ready Mix plant in California.  Read their case study on ALAR’s website.

If you are attending the World of Concrete in Las Vegas this week, please be sure to stop by our booth for more detailed information.

Non-Potable Water For The Concrete Industry

ALAR AutoVac (2)

From the National Ready Mixed Concrete Association:  The CA Division of State Architect has drafted a regulation to provide instructions on the use of non-potable water sources for use as mixing water in concrete.  It permits the use of non-potable water that has been qualified within guidelines of ASTM C1602.

The Alar Auto-Vac C-Series Filter has redefined wastewater filtration in the concrete industry.

The filter uses vacuum technology. A rotating drum is pre-coated with a filter media called diatomaceous earth (DE).

After the pre-coat is complete, cement fines are pumped into the pan where the drum is rotating, the vacuum

pulls the clean water through the drum and traps solids larger than 1/2 micron on the DE surface.

After the surface of the drum is blinded, a variable speed blade advances and removes the solids from the drum surface

leaving a clean layer of filter media.  The clean water is pumped to a non-potable water tank for reuse.

Concrete Operations Include but Not Limited To:

Ready Mixed – Precast  –  Color/Iron Oxide Pigments  –  Sawing/Grinding/Grooving/Polishing/Drilling  –  Roofing & Concrete Tile

The Auto-Vac comes in 16 sizes to accommodate virtually any volume.

Why Treat Wastewater?

Wastewater, also written as waste water, is any water that has been adversely affected in quality by human influence.

Industrial wastewater treatment covers the workings and process used to treat water that has been contaminated in some way by industrial activities prior to its release into the environment or its reuse.

Most industries produce some wastewater although recent trends in the populated world have been to minimize such production or recycle such wastewater within the production.  However, many industries remain prone to processes that produce wastewater and have a need to obtain very high quality water for demanding purposes.

There are several different types of wastewater treatment equipment available; two most known are the rotary vacuum filter and the plate and frame filter press.

Alar builds the Auto-Vac Rotary Vacuum Drum Filter and the Micro-Klean Plate and Frame Filter Press as well as the Flex-O-Star Solid Liquid Separation System and our Slurry-Klean Automatic Plate-n-Frame Filter Press.Alar Wastewater Treatment Fleet

The Alar systems work remarkably well in many industries; Concrete, Flexographic Printing, Food & Dairy, Grease & Septic, Metal Finishing, Paint & Coatings, Oil Rig Drilling Mud, Flowback and Produced Water as well as many other industries.

Wastewater treatment applications include but not limited to: Total Suspended Solids (TSS), Metals, Fat Oil & Grease (FOG), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH (potential Hydrogen).

Contact an Alar Sales Rep to find out which treatment and filter is best suited for your industrial wastewater application.

Trailer Mounted ALAR Auto-Vac for Oil Drilling Rig and Hydraulic Fracturing Wastewater

Trailer Mounted Auto-Vac Alar designs and builds customer industrial wastewater treatment equipment.  Each machine is welded and assembled at Alar’s manufacturing facility then hooked up in the test-bay and put through a rigorous quality diagnostics program by our in-house engineers.

The unit shown in the picture was custom-built for dewatering oil drilling rig and hydraulic fracturing wastewater.

The Auto-Vac was mounted onto a customer-supplied 54 foot trailer.  The Alar production department piped and wired all the plumbing and electrical connections between the skids and auxiliary components.

This Auto-Vac was built to handle severe weather. To prepare for freezing conditions, Alar installed extensive winterized piping and drainage, quick disconnects, industrial heaters, and specialized light fixtures and supports.

The Auto-Vac AV690 is one of the largest mobilized wastewater systems available.  Alar builds larger filters, but they need to be installed at a centralized location.

Alar accepts industrial wastewater challenges of all sizes.  Contact Alar today and find out what filtration system is best for you.
