to diversion and sustainability. Nonhazardous mate-

rials are transformed into nutrient-rich, federally recognized biofertilizers and other multipurpose products. High-speed shearing, alkali and low-pressure steam are applied simultaneously in a reactor to convert organic materials into LysteGro, a com- mercial-grade, Class A EQ biofertilizer with applications in horticulture, agriculture and

soil revitalization. The end product can also be used as a safe, cost-effective, alter-

native carbon source (LysteCarb) in BNR systems. When used in con- junction with anaerobic digestion (LysteMize), the system can reduce volumes by 25 percent while boosting biogas production by 40 percent. The biogas can then be converted into green energy to help power waste- water treatment plants. 888/501-6508; www.lystek.com.

PHILADELPHIA GEAR –

A TIMKEN BRAND CORE

The CORE (Continuous Oil Rescue Equipment) filter from Philadelphia Gear – A Timken Brand can remove particles as small as 1 micron. At the center is a series of annular magnets shrouded by steel plates. When the oil is filtered through these plates, it is subjected to a high magnetic flux gradient caused by the focusing of the magnetic field at the tips of the plates. The

result is that contaminants are drawn into collection areas between the plates

and out of the oil flow. This filtering process results in a negligible pressure drop, while at the same time helping to prevent “wash off” since the contaminant is isolated and cannot wash back into the oil. 800/766-5120; www.philagear.com.

Automation/Optimization

ACOS ADVANCED CHEMICAL

OXIDATION SYSTEMS

The ACOS Advanced Chemical Oxida- tion Systems process can help destroy hazardous organic contaminants in wastewater. Designed to meet individual needs and deg- radation goals, the process generates and applies hydroxyl radicals in a precisely con- trolled, precisely designed environment. With its cocurrent plug flow geometry and process parameters, the process focuses the highest concentration of hydroxyl radicals on the wastewater with the highest concentration of contaminants, resulting in hazardous contaminants being destroyed rapidly, efficiently and cost- effectively. 267/614-8478; www.acos-technologies.com.

ORENCO CONTROLS OLS SERIES

Corrosion-resistant OLS Series control panels from Orenco Controls contain integrated variable-frequency drives to optimize system operation, reduce energy usage and decrease hard starts and water hammer. They’re ideal for any pumping application where consistent flow and energy- efficient operation are essential, such as lift stations, dewatering or sludge pumping. They can also be used as a SCADA patch,

connecting peripheral equipment to an existing SCADA system. Each

AQUA-AEROBIC SYSTEMS

AQUAPRIME

The AquaPrime cloth-media filtration system from Aqua-Aerobic Systems is an economical and efficient solution for primary wastewater treatment and wet

weather applications. It uses a disc configuration and OptiFiber cloth media to filter screened, de-gritted, raw municipal sewage. It can han- dle high solids applications and sustain low-effluent TSS, making it ideal for both wet weather treatment and primary treatment in lieu of conventional sedimentation systems. It operates in less than 10 percent of a footprint compared to conventional primary settling basins and offers the added advantage of improving gas production in the anaero- bic digestion system. 800/940-5008; www.aqua-aerobic.com.

DELTA COOLING TOWERS

A line of towers from Delta Cooling Towers is constructed from antimicrobial resin, which is fully com- pounded into the base cooling tower material. The resin contains additives that operate on a cellular level to continuously disrupt and prevent uncontrolled growth of microorganisms and biofilm within the cooling tower. The tower designs have a sloped basin and/or basin sweeper system to keep water from becom- ing stagnate, which can lead to microorganism development. Stagnant water areas are also prime breeding grounds for Legionella to grow. 800/289-3358; www.deltacooling.com.

HAYWARD FLOW CONTROL FLUID

HANDLING PRODUCTS

Hayward Flow Control’s thermoplastic fluid handling products can be used in the harshest chemical feed environments. The complete fam- ily of solutions includes solenoid diaphragm metering pumps, pressure relief and back pressure valves, calibration cylin- ders and columns, corporation stops and injection valves and quills. They are easy to install

and can help keep systems working with years of maintenance-free ser- vice. 336/712-9900; www.haywardflowcontrol.com.

OLS Series control panels from Orenco Controls

panel is designed and built specifically for the application and setup needs. Multiple drives can be configured through one user-friendly human-machine interface. Engineers preprogram user interfaces to the site-specific needs of an installation, making the panel virtually plug- and-play. Maintenance staff can easily adjust settings and monitor the system remotely. These outdoor-rated control panels, housed in a weath- erproof enclosures, also offer circuit protection, heat dissipation systems (fan or A/C), phase and voltage protection, and level controls. 877/257- 8712; www.orencocontrols.com.

Biogas

AERZEN BIOGAS BLOWER

Aerzen Biogas Blowers are designed for digester gas applications. These blowers ensure process safety and reliability. Operators can choose from a variety of sizes with intake volume flows from 50 to 1,500 cfm and positive pressure up to 15 psig. 610/380- 0244; www.aerzenusa.com.

BOERGER BIOGAS ROTARY LOBE PUMP

The Biogas Rotary Lobe Pump from Boerger offers biogas operators an effective and wear-resistant solution for pumping biogas sub- strate from renewable resources. At the core of the pump is

the Premium profile steel rotor that ensures fibers in the pumped medium actually become part of the short-term surface. They attach themselves in the grooves and are continuously renewed each time the rotor turns. This organic short-term surface provides full protection from wear and the profile rotor itself shows virtually no signs of wear even when subjected to long-term exposure. It is constructed using a maintenance-in-place design, which allows for all wetted parts to be replaced without the removal of pipe or drive systems. 612/435-7300; www.boerger.com.

FCI - FLUID COMPONENTS

INTERNATIONAL ST75 SERIES

The ST75 Series air/gas flowmeter from FCI - Fluid Components International operates in hot, wet, dirty environments to provide accurate measurement of mixed composition gases, including hydrogen, carbon monox- ide and trace methane for biomass gasification. With its advanced thermal dispersion mass flow-sensing element, it measures mixed composition gases, can be configured to operate in cramped areas with

limited pipe runs, and is safe for potentially flammable or explosive

combustible gas environments. It operates over a wide flow range in mixed gas environments from 0.01 to 559 scfm, depending on line size. For variable process conditions such as those in biomass gasification plants, it is factory preset to a turndown range of 10-to-1 to 100-to-1. It has dependable accuracy to plus-or-minus 2 percent of reading with plus-or-minus 0.5 percent repeatability in line sizes from 0.25 to 2 inches. 800/854-1993; www.fluidcomponents.com.

JDV EQUIPMENT CORPORATION DOUBLE

MEMBRANE BIOGAS HOLDER

The Double Membrane Biogas Holder from JDV Equipment Cor-

poration allows variable biogas stor- age within the inner membrane at constant pressure during gas production and usage, while the air- inflated outer membrane provides gas pressure and protection. The outer membrane is constructed of a high-tech cross-woven fabric, coated with PVC and UV protection. Sensors monitor gas volume, allowing operators to optimize the use of biogas to feed generators or heating systems. 973/366-6556; www.jdvequipment.com.

UNISON SOLUTIONS BIOCNG

The BioCNG from Unison Solutions converts biogas to renewable natural gas with a methane quality that meets SAE J1616 fuel requirements for compressed natural gas vehicles. Systems remove hydrogen sulfide, moisture, siloxanes and carbon dioxide from the gas using technology from biogas to

energy systems. All components are based on each location’s specific gas quality and requirements. The systems are capable of producing up to a 2,400 gasoline gallon equivalent per day, and can be supple- mented with natural gas. Exist- ing biogas cogeneration systems

may also be upgraded to provide both fuel for the current cogeneration equipment and produce renewable natural gas for vehicle fueling. Systems provide fuel to both time-fill and fast-fill fueling stations. 563/585-0967; www.unisonsolutions.com.
