FOG Wastewater Treatment
Worldwide commercial and industrial manufacturing operations require the best available wastewater technology to achieve fat, oil and grease (FOG) discharge compliance. Petroleum and commercial product manufacturing industries that discharge wastewater into municipal sanitary sewers or waterways are facing strict fat, oil and grease regulations.
As a direct manufacturer of chemical pretreatment systems, ALAR Water Treatment provides these industries with cost effective wastewater equipment solutions to help achieve FOG wastewater discharge compliance.

Oilfield-related operations measure their industrial discharge amounts as Total Oil and Grease (TOG) and Total Petroleum Hydrocarbons (TPH). Whereas food processing or manufacturing facilities that produce wastewater containing fats, oils, waxes, soaps or the like, measure their industrial discharge as Fat Oil and Grease (FOG).
Environmental agencies monitor and limit the levels of industrial wastewater contaminants a facility is allowed to discharge into sewers and waterways. To comply with oil and grease discharge limits, commercial production and manufacturing industries are required to implement a wastewater pretreatment or disposal program. Some companies choose industrial liquid waste hauling as a means of disposal. Others opt to install waste treatment and filtration technology at their plant.
ALAR Water Treatment is a direct-manufacturer of chemical pretreatment systems, along with mechanical liquid-solid separation and sludge dewatering equipment. ALAR’s industrial wastewater technology can integrate into an operation as a complete system or retrofit to existing machinery. These custom-built systems specialize in meeting environmental discharge and disposal compliance regulations for: TSS, FOG, Metals and BOD reduction; along with pH adjustment or neutralization.
ALAR provides access to a variety of cost effective solutions for commercial production and manufacturing water pollution control problems. Let ALAR help determine the best industrial wastewater process by guiding you through the steps to achieving your company’s water compliance initiatives.
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 mechanical and chemical pretreatment systems that allow customers to make an educated decision.
ALAR’s Auto-Vac®, Flex-O-Star®, and Dissolved Air Floatation systems effectively remove 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 DAF / Dissolved Air Flotation System is a wastewater clarification system that incorporates dissolved air to aid in the flotation of fine solids, fats, oils and grease. The concentrated float is skimmed off the surface with a sweeping wiper blade and discharged into a sludge trough. The sludge is disposed of or pumped to a dewatering filter.
The ALAR Chemical Pretreatment and pH Neutralization Equipment is designed to meet effluent discharge compliance via batch treatment and dewatering or simple pH neutralization and disposal. Sometimes, pH adjusting wastewater, without filtration, through a neutralization system meets city sewer discharge requirements.
However, many industrial wastewaters containing emulsified solids, oils, soaps, surfactants, or dissolved metals require pH adjustment in order to precipitate [drop] out of solution prior to filtration or dewatering.
The majority of ALAR wastewater treatment systems are pH driven; oftentimes requiring acid to lower the pH and break the emulsification, followed by caustic to raise the pH and precipitate the contaminants. In most cases, this simple pH adjustment is all the solids, oils and metals require to be captured by a 1-micron precoat filter such as the Auto-Vac®, Flex-O-Star®.
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.
