McIlvaine Company has identified a distinct liquid macrofiltration market, which it expects to generate revenues of $6 bil. this year. However, McIlvaine says the market is undergoing transformation due to a number of key acquisitions highlighted in the following.
Filtration Group acquired Clear Edge:
Effective May 3rd, Clear Edge was acquired by Filtration Group Corporation, a Chicago based filtration company owned by Madison Capital Partners. Filtration Group, a collection of over 10 specialized= filtration companies, will have revenues in excess of $700 M including Clear Edge.  Clear Edge will be part of the Liquid Process Division within Filtration Group, which also includes Global Filter and Jonell, both specialized industrial process filtration companies. Clear Edge will continue to be headquartered in Tulsa, Oklahoma and operate throughout the world focused on mining and minerals, chemical processing, wastewater treatment and bulk food and beverage markets among other specialized markets and applications. McIlvaine says the acquisition positions Clear Edge to continue to grow within its existing markets and with new products and into new geographic regions."

Passavant-Geiger Acquired Johnson Screens: Passavant-Geiger GmbH, a wholly-owned subsidiary of Bilfinger SE, has acquired Johnson Screens.  The two companies will form the Bilfinger Water Technologies Group, to be headquartered in Aarbergen, Germany.  Minnesota-based Johnson Screens manufactures mechanical components for the separation of solids from liquids and gases, and offers related services from 11 locations around the world. The products are used for drinking water treatment, wastewater treatment, and in oil and gas and refining applications. Johnson Screens has revenues of approximately Euro 160 M ($210 M USD).

As a result of the take-over, Passavant-Geiger will double its revenue to over Euro 300 M ($390 M USD), according to McIlvaine. The newly formed Bilfinger Water Technologies will include Passavant Water Technologies (wastewater purification and sludge treatment), Roediger (vacuum technologies), Airvac Water Technologies, Johnson Screens, Bilfinger (filter presses, formerly Diemme) and China's Bilfinger Passavant Water Technologies (Hangzhou). The new group will have about 1,750 employees at 31 locations in 17 countries.
Vance Street Capital Acquired Micronics: Vance Street Capital LLC, a Los Angeles-based private equity firm, has acquired a majority interest in Micronics Inc., a global provider of aftermarket filtration products and OEM custom filter presses.  Micronics' management team will also have a significant ownership stake in the business. Terms of the transaction were not disclosed.
Headquartered in Portsmouth, New Hampshire, Micronics provides filtration products to varied industries worldwide including mining, chemical, wastewater, metals, and food and beverage. The Micronics transaction represents Vance Street's seventh platform acquisition in its current fund.
Siemens Water Technologies Acquired IPM: Siemens has expanded its dewatering product line with the acquisition of Industrial Process Machinery (IPM), a leading provider of filter presses for the mining industry for over 20 years. Siemens Water will offer IPM's high-capacity filter presses for slurry dewatering worldwide.  Dave Spyker, executive vice president of the Industrial Segment for Siemens Water Technologies, said: "IPM has a strong reputation in the mining market with their filter presses.  The acquisition expands our filter press line of products and related services further into the global mining market and into other industries as well, including chemical and remediation."
IPM provides a unique line of filter presses that are robust and highly automated, offering shorter filter press cycle times and high speed shifting, resulting in reduced cost. IPM filter presses provide such high cake dryness that thermal drying equipment may not be needed, further reducing operating expenses. The IPM filter press will be incorporated into the existing Siemens dewatering product portfolio, which includes the J-Press line of filter presses.
CECO Environment Acquired Met-Pro Corporation: Cincinnati-based CECO Environmental Corp., acquired Met-Pro Corp. in a deal valued at approximately $210 M. Met-Pro makes pumps, filters and water-treatment equipment. The company was founded in 1966 and is headquartered in Harleysville, Pennsylvania.
CECO said the acquisition creates a company that would have a leading share in the global market for air pollution control, product recovery and fluid handling technology. It also expands the company's product lineup and worldwide customer base.
WesTech Relaunches Microfloc, General Filter Brands: WesTech Engineering, Inc. is reintroducing the Microfloc and General Filter brands to the municipal water treatment market. WesTech acquired the product lines from Siemens in September 2012 and believes the brand names went under-promoted under Siemens. The brand reintroduction initiative recognizes the solid reputation the brands hold and honors their successful legacy.
Microfloc was founded in 1961 by engineers who developed an innovative method for electronic control of coagulation chemical addition. Microfloc has continued to innovate, developing the mixed media filter bed, the first commercially viable tube settler, the upflow Adsorption Clarifier System and, more recently, the Trident HS system, a sophisticated package treatment system.
General Filter was founded in 1935 and manufactures water treatment equipment such as pressure filters, clarifiers and aerators. The company's innovations have included the ATOMERATORT system (designed to introduce oxygen into process streams without breaking system pressure), the MULTICELL common-underdrain filter system, the AERALATER package treatment system, Laser Shield direct-retention underdrain caps, and the MULTIWASH backwash system.
Nederman Acquired Environmental Filtration Technologies: Nederman has strengthened its position in the filtration sector by acquiring Environmental Filtration Technologies (EFT). EFT markets filtration products under the well-known brand names of MikroPul, Menardi, Filtrex, LCI and Pneumafil.   The EFT group has the majority of its sales in North America with subsidiaries in Australia, Germany and France. EFT is a major supplier of filter cloths.

The acquisition will significantly strengthen Nederman's position in North American and Australia. EFT also exports to growth markets where Nederman is already present, which can be utilized for further expansion. The purchase price was approximately MSEK 249 (US$39 M).  EFT had sales of MSEK 834 (US$130 M) in 2011, with a workforce of 385.
Alfa Laval Acquired Ashbrook Simon-Hartley: Alfa Laval has expanded in wastewater treatment portfolio with the acquisition of belt filter press manufacturer Ashbrook Simon-Hartley. Headquartered in Houston, Texas, Ashbrook Simon-Hartley has offices in the UK, Chile and Brazil and a worldwide installed base. The company had sales of approximately US $75 M in 2011 and employs about 250 people.
The Ashbrook Simon-Hartley product range, including belt filter presses, decanter centrifuges, rotary drum thickeners and disc filters, complements Alfa Laval's dewatering product portfolio.  Alfa Laval president and CEO, Lars Renström, said: "With this acquisition we are adding a complementary and expanded range of products and solutions further strengthening our offer for municipal and industrial wastewater treatment applications."
Trojan Technologies Acquired Norway's Salsnes Filter: Salsnes Filter AS of Namsos, Norway, will join the group of businesses owned by Ontario-based Trojan Technologies. Salsnes Filter's patented technology uses a fine mesh sieve to filter process and wastewaters and operates like an inclined gravity belt thickener. The fully automated filter is used in the food, paper, cruise line, and aquaculture sectors. The technology is also used as an alternative to the primary settling stage for traditional chemical/biological treatment facilities and to prevent membrane bioreactor fouling.
