What’s New in Treatment?

Advanced treatment units continue to break new ground in product and technology innovation and government certifications

Each year brings innovations in advanced treatment units — not only brand-new systems but also line extensions, new components and capabilities, new test results verifying treatment performance, and approvals for specific systems’ use in new states and provinces. Here is a look at the latest developments in advanced treatment units.

New product lines

The redesigned Remediator and Pro Line kits from Aero-Stream LLC have greater reserve capacity and reduce sound output by 75 percent. The Pro Line Plus handles high flows and high-strength influent and is U.S. and Canada UL listed. The Aero-Alert battery-powered multifunction alarm system uses advanced LEDs and piezoelectronics. Contractors can install the system without a licensed electrician or electrical permit. The unit alarm signals for more than 60 days. 877/254-7093; www.aero-stream.com.

Approved in all states

S-400 and S-600 SludgeHammer aerobic bacterial generators are certified by the International Association of Plumbing and Mechanical Officials Research and Testing Inc. and to NSF/ANSI Standard 40 as advanced treatment systems for residential wastewater. The models are approved in all states. Most units are engineered for subsurface drip disposal. The generators use microbes to process waste in the septic tank. Then the organisms migrate to and remediate clogged leachfields. Digestion of effluent is so complete that nothing remains to create a biomat, the company states. The units are designed as cost-effective options when repairing or replacing failed absorption beds. 800/426-3349; www.sludgehammer.net.

Installation ready

The Model J-500CF nutrient reduction system from Jet Inc. uses intermittent aeration and additional filtration to reduce total nitrogen. The prefabricated unit meets NSF Standard 40 and 245 for reduction of TSS, BOD, and total nitrogen. The system includes the 700LL aerator, attached pretreatment tank, and biologically accelerated treatment media process to transform wastewater into colorless, odorless effluent. 800/321-6960; www.jetincorp.com.

High-strength MBR

The BioBarrier high-strength membrane bioreactor (HSMBR) from Bio-Microbics Inc., is designed for residential or commercial applications with high-strength effluent in flows from 500 to 9,000 gpd. Acting as a physical barrier for nearly all common pollutants in wastewater and greywater, the system avoids fouling of the sheets by inorganic solids with ultrafiltration and microfiltration flat-sheet membranes with pore sizes down to 0.03 to 1.1 microns.

The operation sequence requires no complex backwashing and is completely automated. It is based on the same technology as the NSF-certified BioBarrier MBR and produces high-quality effluent that provides water reuse opportunities. The pre-engineered, modular unit ships installation-ready and fits into new and existing tank configurations. 800/753-3278; www.biomicrobics.com.

Aerobic bacterial generator

Failing wastewater drainfields can be rejuvenated in as little as two weeks with the Aquaworx Remediator. Installed with minimal landscape disruption, the system is inserted into the existing septic tank and reverses the biological clogging process that caused the failure. The unit is designed to be inexpensive to install, operate and maintain. 877/278-2979; www.infiltratorsystems.com.

New systems

The AdvanTex AX20-RT and AX20-RTN three-in-one treatment, recirculating and dosing systems from Orenco Systems Inc. come with factory settings and “plug-and-play” installation. The 5- by 8.5- by 6-foot-high watertight fiberglass basins install like a tank. Effluent recirculates without a splitter valve. Systems are NSF-approved to produce less than 10 mg/l BOD and TSS and reduce nitrogen by more than 60 percent. Rated at 500 gpd, the units have a VeriComm remote telemetry control panel or MVP digital programmable controller. 800/348-9843; www.orenco.com.

Nutrient reduction

A nutrient reduction system from Enviro-Flo Inc. accomplishes nutrient reduction without added pumps or chemicals. The system, which has no moving parts, is simple to install with minimal plumbing. The company’s NSF Standard 40 HDPE aerobic treatment tanks have a ribbed-arch shape for ease of back-filling. Access openings accommodate standard risers. Weighing less than 600 pounds, the systems include a pretreatment chamber, a pump chamber, or both, and can be set without machinery. 877/836-8476; www.enviro-flo.com.

More capacity

Fusion series wastewater treatment systems from Clarus Environmental, a division of Zoeller Pump Co., are now approved in Georgia and Texas. Units treating 1,120 to 2,800 gpd are available for clustered and commercial applications. 877/244-9340; www.zoeller.com.

Membrane bioreactor

Membrex from Premier Tech Aqua combines biological activated sludge treatment with submerged membrane ultrafiltration to meet discharge requirements for nitrogen and phosphorus removal and disinfection. Designed for commercial and community applications, the system also meets California Title 22 requirements for effluent reuse. 800/632-6356; www.premiertechaqua.com.
