RO treatment system
N.A. Water Systems, a Veolia Water Solutions & Technologies (VWS) company, has received a patent for its AMDRO™ technology, a reverse osmosis (RO) process for treatment of acidic wastewater. This process is particularly applicable to the mining and fertilizer production industries. The patented process includes VWS’ proprietary ACTIFLO® clarification technology and media filtration for pretreatment, followed by a doublepass RO and ion exchange polishing to produce a treated water stream suitable for discharge and reuse. The key to the technology is the operation of the pretreatment and the first-pass reverse osmosis process under acidic conditions to inhibit the precipitation of scaleforming compounds.

Desalination pre-treatment
ITT’s Water & Wastewater group offers two desalination pretreatment system technologies—the Leopold® Clari-DAF® dissolved air flotation system and Leopold FilterWorx® rapid gravity media filtration. They can be used individually or in combination to provide influent to feed RO membrane filters. The Clari-DAF system requires no polymer, has high loading rates, is compact in design and effectively operates in low temperature raw water. It features a rapid start-up with good quality effluent achievable within 45 minutes. The FilterWorx rapid gravity media filter system has a downflow design, efficiently stores solids, handles wide swings in solids loading, and provides long filter runs with high production rates. It is also versatile in meeting a variety of source water conditions and can be designed to a variety of site conditions or existing filter basins.

On-site treatment
Bio-Microbics has introduced a new generation of wastewater treatment solutions for onsite and decentralized treatment. Its BioBarrier® Membrane Bioreactor (MBR) helps meet the increasingly stringent needs of environmentally sensitive areas. The preengineered, modular system uses flat-sheet membranes and is completely automated using advanced control strategies. It ships ready to install in new and existing tank configurations. The membranes and processes used in the system act as an impenetrable physical barrier for nearly all common pollutants found in wastewater.

Suspended solids meter
Easily measure the concentration of sludge’s or slurries without the reading being affected by color using the Markland Model 502 Suspended Solids Meter. The meter can be used in drinking water plants to measure the concentration of the backwash sludge from sand or membrane filters before it is sent for further processing. In wastewater treatment plants it is used to measure primary, secondary and return activated sludges. The syst e m uses the attenuation of ultrasound to read the concentration. The meter can be mounted in open-top tanks or pipelines.

EDI, membrane system
With Septron Bio-Safe, Christ now offers the world’s first electro-deionization module with an integrated membrane stage. It is based on the proven and patented spiral-wound technology and has an additional membrane stage for removal of particles and bacteria. The EDI module is available in a cold-water version and a version which can be sanitized with hot water. Both versions are available in various sizes with outputs of 500 to 3,000 l/h. The combination of this module with a preceding reverse osmosis stage makes it possible – without additional ultrafiltration – to produce Highly Purified Water (HPW) with bacterial counts of = 10 CFU/100 ml. The module can be retrofitted on existing Osmotron systems and permits a considerable improvement in the microbiological safety of existing pure water systems.

Band Screen
The Headworks Eliminator™ Band Screen protects MBR plants and sensitive biological systems with very fine openings by eliminating carry-over and by-pass. This design forms a continuous band which travels parallel with the channel wall. The water enters through the center of the screen, passes through the stainless steel sieve elements and exits through the sides of the unit. Screenings are captured by the elements and are carried up to the discharge point where they are removed by a Dual-Surge™ spray header system. The material is discharged into a sluice trough and conveyed for collection and disposal, typically to a screenings washing and dewatering system.

RO Elements
Toray Membrane USA has introduced two new low pressure brackish models of TMG20-400C and TMG20-430C reverse osmosis membrane elements. The new products feature a new permeate tube design that standardizes permeate tube dimensions without the need for special adaptors when replacing competitor elements. The company also offers new 34 mil brine spacers for models of TM720N-400 high rejection brackish elements and TMG20N-400 low pressure brackish elements. The thicker brine spacer makes the element more resistant to fouling and easier to clean in waters with higher suspended solids and difficult process water applications.

MBR system
The Smith & Loveless Titan MBR™ combines efficient pre-engineered system design with S&L Flat-Plate Membranes. Submerged in the aeration section of the tank, the membrane maintains high permeability and flux rates even at peak-day rates. Because the system employs air scouring to prevent fouling, it does not require back-pulsing or the associated equipment and chemical costs typical of other systems. Because of its robust support, Flat-Plate units also experience less wear and tear than hollow-fiber types and can be cleaned in place. The MBR systems come in standard and custom designs, and result in smaller footprints than conventional systems. Custom options can be included based on the desired effluent characteristics. Flow capacities range from 5,000 gpd to 3 mgd.
