Columbia River Carbonates was established in 1985 as a supplier of high grade, ultra-fine ground calcium carbonate throughout the Northwestern United States, Western Canada, and the Pacific Rim.
The company is a joint venture between Omya, a leading global producer of industrial minerals and a worldwide distributor of specialty chemicals, and Bleeck Management, Inc., a family-owned business, which has been in the calcium carbonate business since 1850. Combined, this experience provides our customers with technically advanced products, competent technical service and advice, and the resolve to help find the answers to their current and future problems.
As a joint venture between Bleeck Management, Inc., and Omya, the company incorporates the highest level of manufacturing, technical experience and expertise of both owners, each of whom have been active in calcium carbonate production and technical development for generations. Bleeck Management, Inc., is owned by a family which has been in the business of calcium carbonate mining and processing since the 19th Century. Omya, founded in 1884, is a leading global producer of industrial minerals and a worldwide distributor of specialty chemicals.
Municipal Wastewater
- Non-hazardous alkali for replacement of higher hazard alkalis including sodium hydroxide, sodium carbonate and lime and higher-cost equivalent hazard magnesium hydroxide or calcium hydroxide when used for alkalinity control of recycled activated sludge in aerobic biological treatment processes including conventional, MBR and MBBR
Municipal Drinking Water
- Cost-efficient, non-hazardous calcium product for replacement of calcium hydroxide when a need to increase hardness of incoming water exists prior to initial media filtration
Industrial Wastewater and Process Water
- Non-hazardous alkali for replacement of higher hazard alkalis including sodium hydroxide, sodium carbonate and lime and higher-cost equivalent hazard magnesium hydroxide or calcium hydroxide when used for alkalinity control of recycled activated sludge in aerobic biological treatment processes including conventional, MBR and MBBR
- Non-hazardous alkali for replacement of higher hazard alkalis including sodium hydroxide, sodium carbonate and lime used for pH adjustment of low pH process stream that is being EITHER sent to a pretreatment plant ahead of a POTW (e.g. anaerobic digester) to remove BOD and/or TSS or being discharged directly to agricultural use land as sludge (e.g., WAS) under an approved annual land use management plan administered by a state of municipal agency and/or as aerobically treated water discharged into a received water under NPDES permit administered by State EPA
Commonly used alkalinity and pH control additives used in municipal and industrial wastewater treatment processes including Sodium Hydroxide (commonly referred to as Caustic Soda), Magnesium Hydroxide and Calcium Hydroxide (and sometimes a combination of these latter two products) have a much larger energy demand during manufacture as compared to MICRONATM Aquacal dry and high-activity aqueous slurries) that minimize environmental footprint that could be successfully be achieved by utilizing products manufactured by Columbia River Carbonates.
