TRL-1

Development is designed for water treatment and water treatment systems, namely for membrane water treatment plants.

Market and Economic Attractiveness

An important component of operating costs for membrane equipment is the replacement of modules. Optimization of regeneration cycles will increase the duration of modules without replacement. At the same time, the costs of energy and reagents used in regeneration increase. A scientifically grounded definition of the need to start regeneration will reduce energy and reagent costs. The cost of recycling spent membrane modules and wastewater after regeneration is also reduced.

Main Advantages (Strengths) of the Device

  • The operation of reverse osmosis systems is limited by contamination of the membrane surface, therefore, for the reliable operation of such installations, it is necessary to periodically carry out the procedure for the regeneration of contaminated membrane modules.
  • At the moment, the most justified are the recommendations of Hydranautics, set out in the technical bulletins (https://www.lenntech.com/Data-sheets/Hydranautics-TSB107-L.pdf). The disadvantage of these recommendations is the reference to qualitative characteristics and the lack of quantitative assessment of the presence of pollution.
  • The proposed regulation makes it possible to assess the presence of contamination by the majestic resistance of the sediment layer, which is determined by the operating parameters of the membrane installation, which will allow timely detection of contamination and optimize the regeneration cycle.
