Auto-Jet®Pressure Leaf Filter

Auto-Jet® is the premium self-cleaning leaf filter designed for efficient filtration in the most severe applications. Due to a superior, patented sluicing design, Auto-Jet maintains its full-rated capacity even where heavy, sticky or unusually tenacious cake is encountered. Its uniform leaf construction enables leaf interchangeability and provides uniform precoating, filtration and cake build-up. Available in wet or dry cake models, our standard sizes range from 50 to 2000 ft2 for a variety of applications including sanitary design.

Filtra-Matic®Pressure Leaf Filter

Filtra-Matic® is a versatile pressure leaf filter designed to provide operating efficiency and easy maintenance for high-volume applications or where a dry cake discharge is desired. This filter is offered in two basic models: Filtra-Matic® RT with its unique retracting tank and Filtra-Matic® RB featuring a retracting bundle design. An automatic wet sluice cleaning cycle scrubs the leaf surfaces and assists in cake removal. Dry cake can be achieved with gas or steam injection into the air inlet.

Power Clean®Nutshell Filter

Powerclean tanks  for removal of suspended solids and hydrocarbons

Power Clean® nutshell filters are unparalleled in removing free oil and suspended solids from water. Ideal for produced water or a variety of other industrial applications, Power Clean filters reclaim more oil than conventional techniques. In this automated system, the media is cleaned in only 12 minutes with only 5% media loss per year, making Power Clean an efficient, cost-effective process for managing oily water.

L’eau Claire Upflow Filter

L’eau Claire upflow deep bed media filters provide a ready clarification solution. Its installed cost is less than that of a conventional sedimentation basin and filter system, requiring 75% less space. Total automation and minimal levels of chemical feed hold operating costs to a minimum. L’eau Claire delivers water with a total suspended solids content that is virtually independent of influent concentrations. This cost-effective process does not use clarifiers, flocculation, sedimentation or mixers.

Auto-Shok® Candle Filter

Auto-Shok® is a classical tubular filter, ideal where a high flow rate per unit of filter area is required. Tubes are mounted vertically, attaching to a tube sheet at the top of the tank. Cleaned through a backwash cycle, Auto-Shok is simple, requires fewer valves than other types of filters, and is easily automated to fit the process requirements.

Auto-Pulse™ Candle Filter

Auto-Pulse™ is designed to accomplish sub-micron filtration without the use of precoats or filter aids, making it possible for product to be recovered from waste streams and returned to the process stream without contamination. These tubular filters can be provided with a variety of membranes to cover the tubes, depending on your application. Backpulse “bump and run” operation ensures efficient filtration, effective cake removal and consistent effluent quality.

High-Rate Downflow (HRD) Filters

High-Rate Downflow (HRD) sand filters offer high performance filtration even in difficult process applications. The flux rate is typically 5-20 gallons per minute per square foot. These filters utilize a proven distribution design to enable excellent hydraulic coverage during high-rate operation. The high velocity can drive the solids deeper into the media bed and achieve higher solids loading and extended run cycles. Typical media types are silica sand, garnet and anthracite. Air scour blowers and backwash pump systems are provided for proper cleaning of the media.

Co-Strip™ Degasification Technology

Co-Strip Degasifier

Co-Strip™ is ideal for degasification of water streams with high oil and suspended solids loadings. Unlike conventional packed towers, Co-Strip effectively removes dissolved gases such as BTEX, CO2, and H2S from water without the need for filtration upstream of the degasification operation, saving off-gas treatment costs. In addition to our proprietary product, Veolia offers a variety of packed tower gas strippers, including forced-draft or vacuum degasifiers. Our industry experts will help you determine the most cost-effective product to meet your needs.

AutoFlot®Induced Gas Flotation (IGF)

AutoFlot® is a horizontal induced gas flotation system designed to effectively remove free and emulsified oil and suspended solids from water. Available in both mechanical and hydraulic designs, each unit consists of a horizontal cylindrical vessel divided into four in-line flotation cells. Each chamber successively removes the oily froth, resulting in greater than 95% oil removal.

Corrugated Plate Separators (CPI)

Corrugated Plate Separators (CPI) are used for oil/ water separation in a large range of applications. The plate pack is customizable in regard to inclination, plate spacing and material. Typical removal rates for CPI technology range from 50 to >90% of oil and 80 to 90% of total suspended solids (TSS).



This modular system is a closed-circuit solution that treats the quench water for reuse and recycles the waste streams. The modular design enables quick, easy installation with prefabricated modules that are factory assembled and tested prior to shipment. The result is a shorter project schedule, reduced cost, and minimization of risks associated with on-site activities.
