Diatomaceous Earth (DE), is an inexpensive natural mineral with honeycomb structure that is ideal for filtering. It is an industrial mineral composed primarily of the skeletal remains of microscopic aquatic plants, called diatoms. Deposits of their skeletal structures accumulated over the millennia, and are now accessible to mining.

Perlite filter media is the alternative to DE that is man-made hydrated, naturally occuring volcanic rock with good clarifying power and large throughputs.

One-Step is an unique bentonite clay based product that absorbs particles while the unique chemical formula acts as a separating agent to encapsulate the solids; removing emulsified oils, ink particles, phosphates and suspended solids from wastewater. It is not a filter aid media, but a pretreatment chemical that is added to wastewater prior to filtration. One-Step can be utilized on existing systems without modification and can be controlled to pH to minimize chemical consumption.

Dry & Liquid Polymers uncoild their molecular chin in order to bridge smaller particles into larger groupings (floc), so that liquid can be released and solids suspend on the filter.
Polymers increase flow rates, enhance effluent quality, conserve DE usage and provide cost savings. ALAR provides a wide range of both anionic and cationic blends used for both coagulation and floccuation of solids.

ALAR is one of the largest distributors of DE in the United States. It is used as a filter precoat for ALAR’s wastewater treatment equipment.

A Filter Press (also known as a Plate-and-Frame Filter Press) removes solids from wastewater and produces a clean effluent.

It is the most widely used method in the treatment of sludge produced by wastewater treatment.

ALAR’s Micro-Klean™ has the following features:

• 2 to 20 cubic feet Size Options
• Heavy Duty Steel Construction
• Automatic Open/Close Ram
• Roll-Off Solids Hopper
• Chemical Batch Treatment Skid Option
• PLC or Manual Control

ALAR also builds a Slurry-Klean™ Filter Press that is an economical compact plate-n-frame filter press with the ability to filter and purge automatically; providing continuous operation with minimal labor.  The Slurry Klean™ provides an innovative  solution for small batch operations and companies that cut, drill or grind concrete; it is best suited for cured or inactive concrete slurry water recycling.

The Micro-Klean™ and Slurry-Klean™ are made in the USA with easy access to universal parts and 40+ years of ALAR Engineering experience.

New rules from the North Dakota Industrial Commission go into effect April 1, 2012 that will provide stricter regulations to the oil industry.

Specifically, oil companies will now be required to separate liquids and drilling mud from rock cuttings.  The liquids can then be hauled away for disposal or recycling rather than stored in reserve pits.

Governor Jack Dalrymple, who is part of the Commission, said, “We want to do away with open pits for production wastewater.  There are treatment processes available today to clean and recycle these waste liquids  so that we leave a lighter footprint on the environment. Our management and oversight must reflect improvements made possible through new technologies .”

Aware of the upcoming “No Reserve Pit” regulations, ND based Paragon Water Solutions tested conventional methods such as Centrifuges, Hydrocyclones, Filter Presses and Settling Tanks. In each scenario, they hauled out hundreds of barrels of dirty water, and replaced them with truckloads of clean water.

In January 2011, Paragon contacted ALAR Engineering Corporation, a manufacturer of wastewater separation and water recycling equipment, with a need to dewater water-based drilling mud from active circulating systems where other technologies failed. ALAR recommended the Auto-Vac®  rotary vacuum precoat drum; a self-cleaning filter that does not blind or cause bottlenecks, and is forgiving of wastewater variances and thick oily sludge.

A trailer-mounted ALAR system, capable of filtering up to 800 barrels a day, was commissioned in April 2011. A year later the Auto-Vac® continues to filter a combination of wastewaters, producing dry solids and recyclable clean water without the cost and headaches.

Paragon noticed that the Auto-Vac® eliminates the need for reserve pits, which should satisfy the NDIC rule.  Their customers claim that the clean water increases the drilling rate of penetration and reduces mud pump and downhole tool wear and maintenance. The dry solids decrease wet tonnage hauling and water truck traffic congestion.  Most of all, the dollar savings are substantial. Earlier methods cost Paragon customers up to $66 a barrel; Paragon charges much less utilizing their mobilized Auto-Vac®.

Paragon Water Solutions focusses mainly on water-based drilling fluid reserve pit wastewater in the Williston Basin and Bakken Shale Oil Field.  A video of the ALAR Auto-Vac® system in operation is available online at http://www.youtube.com/watch?v=UkZUzEaqh-M

There are Auto-Vac® systems in the infant stage currently filtering hydraulic fracturing production water in PA and NM; showing promising results. ALAR custom builds sixteen (16) filter sizes to accommodate virtually any volume of wastewater.

Dean Trevaskis pumps and hauls commercial greasetrap, residential septic, portable toilet and wine lees near the foothills of the Sierra Nevada Mountains in Northern California.

In 1999, with several disposal sites closing or raising their discharge fees, Trevaskis opened a private processing plant to dewater over 3.5 million gallons of sludge a year.  The plant turns a profit, and Trevaskis sees a lot of potential for growth and may one day move away from pumping and concentrate solely on the processing business.

Trevaskis was excited to share what he’s learned by hosting an open house this past October (2011) in conjunction with a wastewater sysmposium held by COWA and NAWT.  Sierra Septic showcased their 12-year-old ALAR system consisting of a Rotary Auger Strainer, Super Sack Unloading System and Auto-Vac AV690 Rotary Vacuum Drum Precoat Filter.

PPG Industries constantly seeks to improve pollution and waste prevention programs throughout its global manufacturing facilities.  In 2009, PPG’s Reno Plant took steps to enhance its existing wash water and wastewater management program by implementing an in-house chemical treatment and dewatering system. The Reno plant produces latex paint under the familiar brand names of Olympic and Pittsburgh paints.

Challenge: PPG Industries in Reno, NV., sought a more efficient way to deal with its wash water and wastewater.

Solution: PPG did its due diligence in conducting several performance tests on a complete chemical batch and filter system from Alar Engineering Corporation.

Conclusion: PPG ultimately purchased an ALAR Auto-Vac filter to handle their 12,000 gallons of wastewater per day.  They were able to reduce cross-state sludge handling and disposal costs.

Water pollution control is one of this country’s top priorities. The E.P.A. fueled by growing public pressure, is tightening the regulations on what may and may not be discharged into our sewers or disposed of in landfills.  Liquid waste disposal is virtually non-existent and is completely banned in 98% of the U.S. today.  The government has placed the responsibility of those companies using water in their processes to meet these strict E.P.A. guidelines. These efforts preserve our rivers and streams and ensure safe drinking water far into the future.

To comply with these regulations industries are faced with exorbitant hauling costs, expensive off-site treatment, increased municipal user fees and the burden of cleaning up wastewater lagoons.  Non-compliance results in heavy fines and may even lead to complete plant shut down.

The most sensible and cost-effective solution is to clean up wash water at the source.  ALAR Engineering Corporation has been designing and manufacturing wastewater treatment equipment since 1970.  Utilizing the latest in technology and advanced research methods,  ALAR provides industries of all types with state-of-the-art, time proven equipment.

Wastewater is a problem most companies face.  After the manufacturing process, wastewater or sludge remain an environmental concern.

Some companies simply put it down the sewer or into a lagoon, others haul it away to landfills.   Yet others search out a solution to their problem.

ALAR’s water pollution systems and equipment has been the answer to many companies worldwide.

Since 1970, the ALAR Auto-Vac filter dewaters process and wastewater sludge generated from a wide variety of industries.  Sludge from air floaters, wet scrubbers, and clarifiers can also be dewatered with ease, sharply reducing hauling costs.
