Industrial Landfill Disposal
Worldwide commercial and industrial manufacturing operations require the best available dewatering technology methods to achieve landfill solid waste disposal compliance. ALAR Engineering Corporation provides these industries with cost effective sludge dewatering equipment solutions.
According to the US EPA database, “Modern landfills are well-engineered and managed facilities for the disposal of solid waste. Landfills are located, designed, operated and monitored to ensure compliance with federal regulations…Today’s landfills must meet stringent design, operation and closure requirements established under the Resource Conservation and Recovery Act (RCRA)”.
The government established programs to manage hazardous wastes from cradle to grave. Cradle to grave regulations make an industrial user responsible for disposal, not the facility that accepts the solids.
The majority of landfills consist of three types: Municipal, Industrial or Hazardous. When deciding on a wastewater pretreatment system, an industrial user should confirm what landfill category the solid waste will fall into.
ALAR Engineering Corporation manufactures industrial liquid-solid separation equipment capable of producing landfill-ready solids. ALAR provides access to sludge dewatering systems that typically meet RCRA solid waste compliance regulations without further drying.
Contact ALAR to help determine an industrial wastewater treatment process that complies with effluent discharge and landfill disposal regulations.
ALAR manufactures industrial wastewater treatment equipment for worldwide distribution.
Industrial wastewater is a moving target; no two waste streams are alike. ALAR understands the difference and uses its chemical, engineering and technological expertise to deliver results that work.
Responsible industrial wastewater management makes the difference between regulatory compliance and non-compliance. ALAR offers a variety of wastewater pretreatment and filtration systems designed for sludge dewatering that allow customers to make an educated decision.
ALAR’s Auto-Vac®, Flex-O-Star®, Micro-Klean™ and Clarifier systems effectively remove inorganic solid particles from the liquid, producing clean/dischargeable [non-potable] water along with dewatered dry solids. ALAR also designs and builds industrial chemical pretreatment and pH neutralization systems for batch treatment or continuous flow process wastewater applications.
The ALAR Auto-Vac® is a rotary vacuum drum precoat filter that effectively removes solid particles from the sludge, producing dewatered dry waste. Typically, this waste is disposed of at a local landfill without further drying. The Auto-Vac® is self-cleaning with every revolution, which prevents blinding or clogging, and provides rapid filtration and extremely high filtrate clarity.
The ALAR Auto-Vac® filtering system, available in 16 filter sizes, is skid mounted, pre-piped and pre-wired for easy installation. It is offered in both semi-automatic and automatic modes of operation. This design works with virtually any industrial waste.
The ALAR Flex-O-Star® is an automatic batch or continuous flow chemical pretreatment system, combined with the Auto-Vac® RVDPF technology.
This system provides comprehensive wastewater treatment for water-based effluents, slurries, and problem wash waters. The design is universal and works with virtually any industrial liquid waste. ALAR’s Flex-O-Star® is engineered to incorporate a two-step filtration process: Chemical & Mechanical.
The first step, chemical treatment, breaks the solids and liquids apart by automatically adding pretreatment chemicals such as pH adjusters, polymers (coagulants and flocculants) or clay.
The second step, mechanical filtration, physically removes the precipitated solid particles from the sludge.
The Flex-O-Star® is a skid-mounted, pre-piped and pre-wired system; available in 12 sizes.
The ALAR Micro-Klean™ is a robust pre-piped, solid steel plate-n-frame dewatering filter press; equipped with an automatic hydraulic ram and solids collection bin. The Micro-Klean® will filter the sludge until the solids fill each plate. Over time, the buildup of solids will block any more water from passing through the filter. When the filter press is full, the operator will blow out residual moisture, open the press plates and scrape them down. The solids will fall into a collection bin and the filtrate is discharged into the sewer or returned to the chemical pretreatment cycle.
The Micro-Klean™ is available in 2 to 20 ft3 size options, automatic open/close ram, roll-off solids hopper, chemical batch treatment skid option, PLC or manual control.
Standard TCLP Landfill Test
Disposing dewatered solids to a landfill sometimes requires testing. A detailed test is called a TCLP [Toxicity Characteristic Leaching Procedure]. The TCLP Test is performed by an independent/certified laboratory – ALAR does not perform this test.
Keep in mind that "cradle to grave" laws make your company ultimately responsible for disposal, not the facility that accepts the solids. Therefore, it is wise to perform the independent tests on the solids.
Here are the typical Solid Waste Disposal Parameters used by landfill disposal services:
- TCLP Toxicity Characteristic Leaching Procedure (8 RCRA Metals, VOC, SVOC)
- Reactive Cyanide & Sulfide
- Ignitability (Flashpoint)
- pH (Corrositivity)
- Paint Filter
Most facilities only require the RCRA 8 and Paint Filter Test.
Some disposal service companies provide a TCLP test at no charge and/ or will require a company to fill out a permit application
The ALAR Engineering Department designs each system to meet the customer's build-to specifications. ALAR begins with stock layouts, and customizes the auxiliary equipment according to the customer's specifications.
