Areas of operation General Industrial

Water & Wastewater  
Our filtration and separation solutions for industrial wastewater treatment produce water for recovery and recycle back to the plant, or for direct discharge to drain. Depending on the technology selected, contaminants are either reduced sufficiently for direct discharge or significantly concentrated to substantially reduce hauling costs. Wastewaters from these industries are considered the toughest to treat, containing high levels of suspended solids, oil & grease, heavy metals, BOD and COD.

Ideal for:
• Primary Metal Plants
• Metalworking Operations
• Machining Operations
• Stamping and Rolling Operations
• Plating Facilities
• Electronics

Heavy Metal Removal 
Our filtration and separation solutions for heavy metal wastewater producing industries function to produce filtrate for recovery and recycle back to the plant , or for direct discharge to drain, while concentrating precipitated metals to meet discharge regulations and reduce hauling costs. Filtrate from membranes is substantially lower in concentration of metals, and is significantly more consistent in quality versus conventional gravity separations, with the membrane itself being a true physical barrier. Wastewaters from these industries can be a challenge, but with the application of the correct membrane configurations and our installation experience your problem is solved.

Ideal for:
• Primary Metal Plants
• Metalworking Operations
• Machining Operations
• Stamping and Rolling Operations
• Plating Facilities
• Electronics

Softening & Sulfate Removal 
Our filtration and separation solutions for softening applications work to remove hardness and sulphates from both naturally occurring and industrial source waters. When removing all total dissolved solids is not necessary or desirable, softening can achieve the product water requirements with lower operating costs than full demineralization.

Ideal for:
• Textile Manufacturing
• Pulp & Paper

Amine Purification 
Our amine purification solution effectively removes heat stable salts (HSS) for improved absorber performance, reduced equipment corrosion, and fewer amine purchases.

Ideal for:
• Carbon Capture
• Steel Plants
• Cement Plants
• Coal Gasification
• Hydrogen Plants

Metal Finishing  
Our acid purification technology continuously removes metal contaminants from acid solutions in metal finishing processes such as aluminum anodizing, electroplating, and steel pickling. This results in fewer acid purchases and process downtime, and consistent product quality.

Ideal for:
• Anodizing
• Electroplating
• Pickling

Latex Purification & Concentration  
Our filtration and separation solutions for latex production function to dewater latices off the reactors at a fraction of the cost of evaporation, debottlenecking the plant, while producing filtrate for discharge or reuse. End of pipe wastewater systems at latex plants function to recover valuable latex solids for resale and produce filtrate for discharge.

Ideal for:
• PVC
• SBR
• PVAc
• Latex paints
• Latex glue and binder blends

Recovery of Paints / Dyes / Inks 
Our membranes systems are used to treat wastewaters containg paint, inks, and dye components from tank vessel and cylinder cleanup in printing processes to dye rinsing in textile mills, by separating and concentrating color components from the waste and producing clear filtrate for discharge or recycle. Concentrated high value inks and dyes are often suitable for recovery and reuse.

Ideal for:
• Latex Paint Production
• Printing Operations
• Flexographic Printing
• Rotogravure Intaglio
• Textile Vat Dye Operations

Colloidal Silica Concentration 
Our filtration and separation solutions for colloidal silica production function to dewater the silica slurries off the reactors at a fraction of the cost of evaporation, debottlenecking the plant, while producing filtrate for discharge or reuse.

Ideal for:
• Colloidal Silica Production Plants

Pulp and paper

The pulp and paper industry has experienced a large push to reduce environmental impacts and develop more sustainable practices. We help mills accomplish these goals through the recovery of starch, clay, wood fibers and cellulose from production streams, and the purification and recycle of process chemicals such as caustic and sulfuric acid. We also offer reliable water and wastewater treatment solutions to reduce process water consumption and effluent volumes.

Chloride & Potassium Removal 
One of the most widely recognized limitations to mill operations is the accumulation of non-process elements. Our technology offers an efficient and reliable solution for the separation and removal of contaminants that build up in pulp & paper mills.

Ideal for:
• Kraft mills

Generator Acid Purification
Chlorine dioxide (ClO2) is widely used in pulp bleaching. ClO2 generators continuously purge sulfuric acid to prevent accumulation of sodium sulfate, but our technologies separate waste streams to allow for the recycle of sulfuric acid resulting in dramatic cost savings on acid purchases, fewer shutdowns, and a more efficient process.

Ideal for:
• Kraft mills

Coatings Recovery
 Membrane systems in paper mills are employed as point source break wastewater treatment systems to reduce high solids and COD loading on downstream wastewater treatment, to recover for reuse coatings that are returned to the coating kitchens, and concentrating PVA coatings lost in operations to significantly reduce COD to end of pipe clean-up.

Ideal for:
• Paper Mills

Whitewater Recycle
Membrane systems in paper mills are employed as kidney point-source systems to produce suspended solids free water as substitute for fresh water in critical showers and chemical makeup systems. Further treatment of this filtrate will remove dissolved solids from the mill water loop to improve papermaking production while reducing energy demand. Concentrates from the membrane systems are sold as paper fiber-based by-products.

Ideal for:
• Paper Mills

Flexographic Ink  
Flexographic container, newspaper, and wrapping printing operations require end of run washups that produce high load wastewaters requiring significant pretreatment for discharge. Using a simple one step chemical free membrane system as a point source or end of pipe treatment system allows separation and significant concentration of color bodies, that can be reused or hauled in a concentrated form at a 95+% reduced hauling cost. Filtrate from the membrane operation is discharged.

Ideal for:
• Packaging
• Corrugated Board
• Wrapping Plants
• Newspaper Operations
• Paper Bag Production

Water & Wastewater
Our filtration and separation solutions for pulp and paper wastewater treatment produce water for recovery and recycle back to the plant, or for direct discharge to drain. Depending on the technology selected, contaminants are either reduced sufficiently for direct discharge or significantly concentrated to substantially reduce hauling costs. Wastewaters from these industries are considered among the toughest to treat, containing high levels of suspended solids, chemical dyes, fibrous material, oil & grease, tannins, lignins, BOD and COD.

Ideal for:
• Paper Mills

Color Removal  
Our filtration and separation solutions for pulp and paper wastewater treatment function to reduce wastewater color and produce filtrate for discharge or recovery and recycle. Colored wastewaters from pulp and paper operations can be challenging to treat and direct experience in applying membrane separations on this process is a requirement that we will meet.

Ideal for:
 • Pulp Mills
