High flow filters

Graver High Flow 1301iww

Graver High Flow Series filters have been certified by NSF International under ANSI/NSF Standard 61 as a drinking water system component. The filters feature a large geometry (6" diameter x 40" or 60" lengths) that makes them ideally suited for applications with large daily flow capacities. They are constructed of 100% pure polypropylene, contain no binders, adhesives or surfactants. All materials of construction are FDA listed for food and beverage contact and meet USP Toxicity tests for use in pharmaceutical applications.

RO membranes

Lanxess offers Lewabrane® Reverse Osmosis (RO) membrane elements for desalination and production of high quality water. The Lewabrane RO B090 HF 4040 product type consists of spiral-wound polyamide composite membranes with a surface area that exceed other commercially available elements by almost 6 percent. The bigger surface area results in higher water productivity and creates a superior permeate flow rate. HF (high flow) and HR (high rejection) membranes are available with surface areas of 370, 400 and 440 square feet. The high rejection versions offer more than 99.7% salt rejection measured under standard conditions.

Filtration system

Westech 1301iww

The WWETCO FlexFilter™ from WesTech uses a synthetic compressible media to capture solids in a high rate filtration process. Rising influent applies hydrostatic force to the outside of tapered flexible bladders causing the media within the bladders to compress loosely at the top of the filter, with a tighter porosity gradient through the depth of the filter. This tapered compression provides for a filtration bed that is more open at the top of the filter, graduating to more densely packed synthetic media in the deeper portions of the filtration bed. The simple gravity system includes a unique backwash system involving an air scour coupled with a high energy wash cycle and specialized backwash troughs to minimize the volume of backwash water needed.

Chromate selective resin

ResinTech's chromate selective resin, ResinTech SIR-700, now meets NSF/ANSI-61: Drinking Water System Components - Health Effects for use in all potable water applications. The media has been used successfully at Superfund sites to remove hexavalent chromium from groundwater, in one case offering projected savings to the federal government of up to $20 million. Its unique chemical structure provides tremendous throughput capacity with the ability to load more than 7 pounds of chrome per cubic foot of media under ideal conditions.

Bag filters

Hayward Flv 1301iww

Hayward Flow Control has launched its new FLV Series Bag Filters. The new filters feature a one-piece injection molded platinum GF PP (Glass Filled Polypropylene) body in sizes 1 (16") and 2 (32"). Unlike traditional metal and plastic filters, the series offers a true-union design for multiple end connections and sizes as well as quick installation or removal. They are available in the size range of 1 1/4" through 4" in socket, threaded and flanged connections, as well as optional drill and tap NPT (Offset) ports for interchangeability with existing installations. The FLV series can be ordered as a Simplex through Quadplex unit.

Compressible media filter

Schreiber Fuzzy Filter 1301iww

Schreiber's Fuzzy Filter is a compressible media filter for water and wastewater treatment systems. Media compression permits adjustment of the filter pore size to meet process changes. The filter is very high rate, compact and modular, and is applicable to a wide variety of water and wastewater applications. Operating in an up flow design, the filter achieves an exceptionally high rate of solids removal through the use of synthetic fiber spheres. With loading rates 30-40+ gpm/ft2, the filter requires 20% of the floor space as sand filters. Applications include tertiary wastewater treatment, influent river water, Pre-RO water cleansing, contaminated stormwater, membrane backwash water and cooling water side stream filtration.

Filter cleaning

Blue Earth 1301iww

Blue Earth Labs' filter and trough cleaning product, Filter Fit®, is a low-corrosive, NSF 60 certified solution engineered to remove biofilm, scale, algae deposits and potassium permanganate stains from filtration basins, troughs, clarifiers and other water treatment plant surfaces. The cleaner is applied to surfaces off-line in a low-pressure spray-on/rinse-off process that is safe for virtually all painted and unpainted surfaces including steel, concrete and fiberglass.

Belt filter

Blue Water 1301iww

Blue Water Technologies has launched its latest proprietary product line, the Eco MAT™ rotating belt filter (RBF). The filter is a clarification process with a small footprint that outperforms traditional primary systems for sewage treatment as well as screens and solids-separators in industrial facilities. Four unique models range in sizes suitable for small communities to large cities. There is no limitation in flow capacity designs. The RBF can be customized for varying flow and operational redundancy, facilitating the highest level of treatment for flows in excess of 3 mgd in a single unit.

Tertiary filters

Aqua Minidisk 1301iww

The Aqua MiniDisk tertiary filter features OptiFiber® pile cloth media and is designed to provide economical treatment of smaller flows with the added advantage of retrofitting existing traveling bridge sand filters. The modular design of the filter retrofits neatly into existing 9-foot-wide concrete traveling bridge filter basins, providing more than two times the hydraulic capacity of the original sand filters. The filters achieve low effluent TSS, NTU and phosphorus while offering high solids and hydraulic loading rates, minimal operating and maintenance costs, and a fully automatic PLC control system. The filter is ideal for municipal reuse and phosphorus removal applications, and is also available in steel package units for new construction.

Sand filtration

Parkson Corporation has redesigned the DynaSand® sand filtration system to reduce backwash water volume by as much as 90%, according to the results of a recent trial. The new DynaSand® EcoWash™ minimizes energy use and reject flow by triggering the backwash cycle only for short periods of time. The control system activates the backwash cycle for media washing only when it is required, based on time or the headloss in the filter's feed channel. When the filters are not backwashing, the level of turbidity drops because the filter is actually able to capture more solids in the existing bed when compared to continuous backwash operation. For operators, the new system requires significantly less attention, as the system monitors conditions and cycles through stages automatically.
