At KSS, we recognize the growing need for streamlined process operations and water and wastewater treatment across industrial applications. Our portfolio of separation technologies is backed by decades of experience and our firm commitment to innovation, bringing purification, recovery, and reuse solutions within reach to our customers. From metalworking to manufacturing, our technologies can be applied to tackle the toughest industrial challenges.

Our filtration and separation solutions for softening applications work to remove hardness and sulphates from both naturally occuring 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:
Process Water Conditioning
Our NF membranes and ion exchange systems focus on removing primarily hardness and sulphates, leaving the monovalent ions behind.
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:
Wastewater Treatment
Heavy metals wastewater treatment by ultrafiltration is simply done via pH adjustment and hydroxide precipitation. Target pH for the membrane system’s operation depends on the particular metal’s pH solubility curve. Blends of different heavy metals call for a pH target that best precipitates all of the metals of interest. When simple hydroxide preciptation no longer attains discharge limits, now or when limits are tightened in the future, an easy switch from hydroxide to sulfide precipitation is all that is needed.
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. Our systems solve this problem by not only applying the correct membrane configuration, but by combining these specialized membranes with over 50 years of KSS system design and installation experience on these unforgiving waste streams.

Wastewater Reuse
Pretreated TSS free wastewaters can be further polished for dissolved solids removal from process water for recycle and reuse, reducing fresh water usage and end of pipe wastewater volume and associated costs.
Our amine purification solution effectively removes heat stable salts (HSS) for improved absorber performance, reduced equipment corrosion, and fewer amine purchases.
Ideal for:
Heat Stable Salt Removal
The AmiPur® system features Recoflo® ion exchange technology to continuously remove HSS from the amine circuit, recycling purified amine back into the process.
Heat Stable Salt Removal in Carbon Capture and Storage
The AmiPur®-CCS system features Recoflo® ion exchange technology to continuously remove HSS from amine circuits in the removal/recovery of CO2 from gases, recycling purified amine back into the process.
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:
Acid Purification
Continuously remove dissolved metals to reduce accumulation and purify acids – including sulfuric acid, phosphoric acid, and pickling acid – in anodizing and electroplating processes.
Metal Recovery
Electroplating processes are subject to some nickel salt loss and sludge generation. Recover nickel lost in drag-out and recycle to the plating bath.
Caustic and acid Recovery
Removing contaminants from caustic and acids to recycle the chemical back to the process.
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:
Wastewater Reuse
Reduce water usage by removing latex and other contaminants using the robust tubular ultrafiltration membranes.
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:
Wastewater
Recovering valuable color bodies for reuse while producing filtrate for reuse or discharge our membrane systems are ideal to treat heavy wastes simply and easily without complication.
Wastewater Reuse
Recover water for reuse, reduce plant fresh water demand, and ease wastewater treatment needs, membrane separation systems are used extensively in these operations. Inks, dyes, and paints are at the same time recovered as valuable product for sales or reuse in production.
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:
Concentration to
final product
Colloidal silica suspension dewatering and precise concentrating, gently and without costly phase change evaporation, by tubular membranes is an estalished and standard operation in this industry.
