Industrial Water Treatment

In most Industrial processes water will commonly be employed as either a feedstock, dilutent, cooling or washing medium. Whatever its use there will be a need for some level of filtration treatment required whether that be upstream or downstream of the process.

Industrial Water Treatment

3M Purification has a long history of supplying proprietary filtration equipment in order to improve the water purity levels within your processes, whether it be on a Power Station’s condensate system, a Chemical Plants DI water treatment facility, or on a High Purity RO system. Our solutions can range from pre-designed off the shelf right through to bespoke engineered pieces of equipment to meet your exact needs.

Our experienced Sales and Engineering staff will assist in supplying the solution best suited to your needs, whether that be from our range of depth filter cartridges (3M Betapure NT-TE or 3M MicroKlean RT), pleated filters (3M High Flow) or bag cartridges (CUNO DF Series). In addition to our filter cartridges, we can supply all the necessary purpose designed hardware required to ensure that your production equipment availability and reliability is maximized whilst reducing the overall cost of filtration.

Process Cooling Water

In a typical cooling water application, two process loops are employed – a process water loop and a cooling water loop. On the process water side, water is pumped to the equipment being cooled. The process water carries away generated heat from the equipment, allowing the equipment to maintain its efficiency and operation at controlled temperatures.

The hot process water is pumped to a heat exchanger, where it transfers the absorbed heat to the cooling water side. The cool process water is then pumped back to the process equipment to absorb more heat. The hot cooling water then returns to a cooling tower, where its absorbed heat is either released through evaporation or convective heat transfer to the atmosphere. The cooling water then returns to the heat exchanger to absorb more heat from the process side.

The performance of the heat exchangers and the cooling tower is directly linked to the water quality within the recirculating processes. 3M Purification can assist in optimizing these processes by employing (3M™ DF Series or 3M™ High Flow) where appropriate.

Deionised (DI) Water

Many chemical and Industrial production plants will have self generated DI water on site as a supplied utility for a variety of process requirements. To achieve the water quality specified may involve the use of a combination of several sequential stages of treatment (such as sand bed, carbon bed, reverse osmosis, cation/anion resins, point of use filtration). Although at each of these stages there will be a need for filtration, the heart of the process is the protection the resins (whether in single of mixed bed configurations) from fouling, and subsequently the release of any resin fines from the beds due to attrition.

3M Purification would recommend the employment of 3M™ Micro-Klean™ RT or 3M™ Betapure™ NT-TE (depending on the purity of the water required) as the pre-filter prior to the resin bed(s) and 3M™ High Flow) downstream of the resin bed installation. By installing effective high quality filters either side of the resin bed will ensure long on-stream life of the beds and a guarantee on the quality exiting the system and prior to use.

Reverse Osmosis (RO) Membrane Protection

Given the nature and structure of RO membranes (often supplied in a spiral wound format) they are very susceptible to accelerated fouling which will require cleaning procedures to be implemented which are costly to the operator on a downtime and chemicals consumed basis.

The membrane supplier will often specify an incoming water quality standard to ensure that the rate of fouling is minimised in operation. Commonly the standard quoted in an influent Silt Density Index (SDI) level of between 3 to 5.

To achieve this standard on a consistent basis it is recognised that a filter rated at 10 micron absolute is needed to deliver this quality. Whether the RO membrane is employed in a Power Plant, Offshore Platform, or an Electronics wafer production facility, 3M Purification has experience in enhancing the performance of the membranes in operation ensuring consistent quality and minimising down time with systems containing either 3M™ Betapure™ NT-TE or 3M™ High Flow) filtration systems.
