  • Case Study - Water Resuse/Recycle

    A leading electronics company faced increasing water costs of both influent and effluent. They contracted Applied Water Solutions for a pilot study using some of the most advanced methods of water purification on effluent from a clean out of place (COP) system. The pilot provided proof of principle of the selected process to recycle some of the DI Water rinse, and justified a ROI of less than one ...

  • Photodegradation of the antihistamine cetirizine in natural waters

    The photodegradation rate of the anti‐histamine cetirizine (Zyrtec®) was investigated in various water matrices. The average observed first‐order photodegradation rate coefficient (kobs), obtained by linear regression of the logarithmic‐transformed cetirizine concentrations versus irradiation time in simulated sunlight, was 0.024 h−1 (n = 6; S.D. ± 0.004) in deionized water (DIW) corresponding ...

  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Methods of Purification by Water Innovations, Inc.

    Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical reduction, and some particulate reduction. ...
