Solutions For Water Treatment

Desalination Membrane Pre-Filtration Pre-filtration is perhaps the most important part of a satisfactory performance of RO unit after the RO membranes themselves. The ability of cartridge filters to remove suspended particulates, colloids from the feed stream greatly impacts the performance and longevity of any RO equipment and specifically the high performance units. Desalination Membrane Fouling Protection SDI and turbidity are the key factors that determine the correct use of any spiral wound RO/NF membrane elements. A good multimedia depth filter followed by robust cartridge filters are designed to decrease “SDI and turbidity” increasing the life span of RO/NF elements as well as allowing continuous high performance of spiral wound RO/NF membrane elements. Desalination Membrane Biofouling Protection Bacteria range in size from 0.2 to 2 microns in width or diameter and from 1 to 10 microns in length for the non-spherical specie, so a 1-micron filter will remove most bacteria and cysts in waters where biofouling is a concern.

Raw Water Treatment Critical to the absolute purity of your finished product is filtration at every stage, including pre-filtration of raw water as it enters the process. DI Water The use of filters on the deionization system is used to treat incoming mains water. Trap filters ensure that the make-up process water is of high-purity by preventing downstream contamination of source water sediment or ion exchange bead migration. Process Water In industrial applications, water treatment is employed to optimize processes such as heating, cooling, processing, cleaning and rinsing. In order to achieve the specific water quality for each application, removal of undesirable contamination must be achieved. Cooling Tower Re-circulation Continuous filtration of cooling tower recirculation is important. Boiler Feed Water It is required to remove rust and scale from boiler feed water to keep equipment operations efficient.

Waste Water and Effluent Treatment Effluent and cooling tower blow-down with other waste streams need to be treated for removal of silica, calcium, magnesium, heavy metal etc. Water Reclaiming Filtration helps to remove particulates to reclaim water for new uses, protect and preserve water resources. Discharge Water Filters with high dirt holding capacity help keep the discharge water clean and environment compliant.

Automatic Backwash Filter System

Filtration

Backwashing

The unfiltered fluid is transported into room P1 through the inlet by means of the feed pump. Separation of particles out of the liquid occurs while the unfiltered fluid flows from room P1 into room P2. Between these both chambers the filter material is installed on a perforated drum. The filtered fluid is discharged through the outlet and goes to the P2-pressure equalizing tank, the spin tank or the P2-control valve. The blockage of the filter material causes a continuously increasing differential pressure ∆P between room P1 and room P2. This increase of the differential pressure is analysed by a PLC control system. After reaching a preselected differential pressure, the backflush will be started.

After the maximum degree of contamination has been reached, the total surface of the filter material is cleaned by a backwash procedure. This takes place by one rotation (360°) of the backwash device. The channel, shaped opening in the backwash strip, which seals to the inside surface of the perforated drum (carrier of the filter material), executes the backwash with the minimum quantity of backwash liquid (filtrate), which is necessary to rinse the filter material from impurities. After having cleaned the whole surface, the backwash device remains in the waiting position until the differential pressure reaches the preselected value again.

Automatic Backwash Filter System

Operating Principle Canfil Is A Fully Automatic Filtration System Filtration The fluid to be filtered is forwarded into the untreated water area of the filter via the inlet pipe, flows through the filter candles fastened to the perforated disc and exits purified through the outlet pipe. The automatic vent separates possible gas and air bubbles. Impurities are kept back within the filter candles and produce an increasing flow resistance.

Status: Filtration

Backwashing As soon as the pressure difference is reached, which can be set on the pressure difference switch, or a pre-selected period of time expires, the automatic backwashing with own medium gets activated. The backwash rotor moves from one bottom opened candle to all other filter candles, without interrupting operations, so that if the backwash valve is opened at the same time all filter candles will be backwashed with the filtered own medium, through flow reversal.

Status: Backwashing

After a full rotation of the backwash rotor, the backwash process is finished and the backwash valve will be closed.

Tubular Membrane Filters

Why Choose POREX Tubular Membrane Filters? •

Porex Tubular Membrane Filter (TMF™) modules contain unique, patented, structural membrane tubes. The superior strength of the membrane/substrate composite allows higher operating and backwash pressures for higher flux and reduced system footprint. The structural composite membrane features PVDF membrane bonded to PVDF substrate or anchored to PE substrate.

POREX Tubular Membrane Filter modules provide consistent, reliable solid/liquid separations and long service life

37

Highly chemical & abrasion resistant

•

Multiple membrane pore sizes available on two different substrate options

•

PE substrate with PVDF membrane offers high-performance tubular membrane with superior operating characteristics

•

Uniform, thermally-bonded omnidirectional substrate pore structure provides an optimized support structure for tubular membranes

•

Patented PVDF substrate with PVDF membrane offers high temperature and enhanced chemical compatibility (pH range of 0-14 standard units)

•

Multiple configurations available to suit your application’s flux and solids level requirements (up to 5% by weight)

Chemical Resistance POREX Porous Plastics are made from thermoplastics that are resistant to a broad spectrum of corrosive chemicals and reagents. Operating Characteristics POREX TMF modules are available in a wide range of configurations from single tube to 61 tube modules. At typical operating pressures of 20-80 psi, clean fluid is forced through the pores of the membrane, while

Material Technology Each POREX Tubular Membrane Filter module contains multiple tubular membranes. These structural membrane tubes are made from a PE or PVDF sintered porous substrate that creates an intricate network of open-celled, omni-directional pores. These substrate pores are then filled with membrane which gives our tubes a unique combination of filtering capability and structural strength.

•

Structural Membrane Technology • No membrane delamination • Uniform chemical and temperature resistance • Membrane fused to substrate

Higher Pressure Resistance • Increased flux • Reduced system size • Improved backpulse efficiency

Tough Uniform Membrane Composite • Surface scratches will not destroy overall structural integrity

suspended particulates remain in the retentate stream. The turbulent flow of the retentate stream prevents the build-up of particles on the inner surface of the tube, providing high flux and prolonged filter life. This turbulent cross-flow performance and large bore tubular design may eliminate the need for prefiltration and should routinely handle high solids levels up to 5% by weight.

Metal Precipitation / Removal

Typical process water systems use RO (Reverse Osmosis) technology as the method of decreasing the level of ions in process water. RO recovery rates normally range from 75-80%, therefore 20-25% of the RO feed water is discharged as wastewater. With the increasing cost of water and waste discharge, more companies are looking to recover and reuse RO reject water. While it is possible to reuse the reject water from an RO by feeding it directly into a 2nd RO unit, the likelihood of scaling or fouling the 2nd RO without pretreatment is rather high. Using a TMF system coupled with lime softening will reduce scaling and enhance the operation of the 2nd RO. Lime softening along with TMF provides very efficient softening, silica reduction and solids removal within a single process scheme. Using this treatment technique, recovery rates can be greater than 95% while assuring substantial reduction of scaling to the RO units. This is an efficient and cost effective method for either retrofitting existing RO systems or incorporating it into newly designed systems.

Industrial processes can often result in waste water contaminated with heavy metals that require treatment prior to discharge or recycling. A treatment system using POREX Tubular Membrane Filter Modules in combination with chemical precipitation provides excellent reduction of heavy metals (Nickel, Zinc, Copper, Lead, Chromium, etc). TMF product water (permeate or filtrate) is ready for either disposal into existing municipal waste systems or further treatment for plant reuse/recycle. Treated effluent levels of less than 1 ppm suspended solids and less than 0.1 ppm metals are typical. Cleaning of the TMF modules is simple and involves the use of standard chemicals which will allow many years of service.
