Gelation Time of Hexamethylenetetramine Polymer Gels Used in Water Shutoff Treatment
Among the methods available to reduce water production, injecting a gelling system composed of a polymer and a crosslinker has been widely used. In this work, a hydrogel was prepared by crosslinking of an aqueous solution containing hexamethylenetetramine (HMTA) as crosslinker, hydrochloric acid (HCl) as an activator, and the co-polymer of 2-acrylamido-2methyl-propanesulfonic-acid sodium salt (...
متن کاملDynamic Simulation of Water Treatment in Pulp and Paper Industry
This paper presents an overview of different modelling and simulation (M & S) methods used in water treatment. Special emphasis is on pulp and paper industry. In chemical water treatment, M & S is successfully used in control design. Hybrid models based on a cascade approach are needed in biological wastewater treatment to cover different operating conditions. Uncertainty handling needs to be i...
متن کاملMembrane Processes for Water Treatment in the Semiconductor Industry
ganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology plays a special role at several points. With the introduction of the 0.25 micron (μm) and 0.18 μm wafer technology, the r...
متن کاملEcologically Friendly Polymer-Metal and Polymer-Metal Oxide Nanocomposites for Complex Water Treatment
In this regard,polymeric supports play a very important role for several reasons including, the ease of their preparation in the most appropriate physical forms (e.g., granulated, fi‐ brous, membranes, etc.), the possibility to produce the macroporous matrices with highly developed surface area and some others. However, the immobilization of NPs on the appro‐ priate polymeric support represents...
