The KSS Causti-COR® Nanofiltration Membrane Systems offer a cost effective, environmentally friendly way to recover the expensive caustic solutions used to clean process equipment. Causti-COR systems utilize our patented SelRO® membranes to recover up to 95% of caustic for reuse by removing low molecular weight organic and inorganic contaminants.
KSS SelRO nanofiltration technology helps textile clients recover concentrated caustic from the fiber and fabric treatment operation. The KSS technology brings large cost savings demonstrating excellent recycled caustic quality, long membrane life and improved process efficiency and reliability under very harsh conditions.
Our filtration and separation solutions for textile wastewater treatment produce filtrate 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 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, BOD and COD. Our systems solve these problems 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 treating scour and other mill wastes by our end-of-pipe wastewater treatment systems.
Pretreated, TSS-free wastewaters can be further polished for dissolved solids removal from process water for recycle and reuse, reducing freshwater usage and end of pipe wastewater volume and associated costs.
Our filtration and separation solutions for textile weaving and dyeing operations function to point source recover size for reuse while retaining significant heat energy, point source separate vat dyes for reuse while producing filtrate for discharge, and treating scour and other mill wastes by our end of pipe wastewater treatment systems.
Whether the dye operation involves dissolved molecules or suspended dyes and pigments, KSS has the technology to treat process and wastewater streams to recover chemicals. NF and RO membranes are used to remove dissolved dyes, while tubular UF membranes are used to recover large dye molecules and pigments.
