  • Method for direct observation of biofilm formation during operation on forward osmosis membranes

    The purpose of this study is to describe a method for direct visual observation of biofilm formation on membranes used in a forward osmosis flow cell. Until recently biofouling research has focused on biofouling during reverse osmosis, and generally examined biofilms after, not during, operation. Direct observation allows for more sensitive measurements of fouling than flux data and membrane autopsies alone. The flow cell proposed here can be used to examine the mechanism of membrane fouling and to systematically examine the effects of surface coatings, membrane materials, and cleaning methods on biofouling using a broad range of process conditions.

  • Design of a photovoltaically operated reverse osmosis plant in off-grid operation for desalination of brackish water

    Photovoltaically operated reverse osmosis plants in off-grid operation constitute a promising system technology for meeting a part of the water requirements in regions without dependable water supply and electric grid system power supply. This paper presents a new procedure for optimum system design configuration. The goal is to provide the cheapest possible water supply while fulfilling all regional and technical boundary conditions. The starting point of the procedure is a rough design based on a load duration curve. Subsequent time sequence simulations which image the system behaviour completely, permit checking of various plant variants for compliance with the boundary conditions. Objective mutual comparisons of the plant variants are possible, also taking the system costs into consideration. The possibilities of the developed procedure are demonstrated taking a village supply in Northeast Brazil as example.

  • Hydro-ionic microthruster for locomotion in low-Reynold'S number ionic fluids

    We have demonstrated a fast, extremely power-efficient, hydro-ionic microthruster that utilizes electro-osmotic propulsion for operation in a low Reynolds-number ionic environment. Powered by an onboard power supply, the microthruster achieves speeds of up to 5.24 cm/s (131 body-lengths/s) while consuming less than 252 nW/(Bodylength/s). It is 31% faster and ~103times more energy-efficient than prior designs. Including the onboard Al-air battery consisting of an Al anode and an Au cathode, the microthruster measures 1400μm (H) × 1400μm (W) × 400μm (L) in dimension and contains a 1000μm-wide, 300μm- long cylindrical thruster channel in the center. With significantly improved speed and drastically higher energy-efficiency, the microthruster opens up new possibilities for various self-powered biomedical applications that can operate within the power budget of modern implantable and integrable microscale batteries and bio-fuel cells.

  • PC based SCADA system for reverse osmosis desalination plants

    Reverse osmosis Desalination plants are a widely used application of water treatment engineering all over the world. Therefore devising control systems for these plants is a must in our modern automated industrial world as different systems has been devised yet their technology became obsolete by time. On the other hand complicated and over rated control systems are not convenient to use with these types of plants, especially for remote areas. Therefore, coming up with a monitoring system to monitor and control a Reverse Osmosis water treatment plant is a convenient solution with computer based software. The plant can be monitored using a PC enhanced with industrial automation software like LABVIEW® and a data acquisition card to build up a SCADA system for the water treatment plant. This work illustrates the structure and the installation of a flexible and low cost SCADA system. An ordinary PC with the appropriate interface and software operates the system. The system is installed to a lab scaled water plant which is designed and built. The system has proved the expediency of PC based SCADA systems over the conventional control systems.

  • Rolling horizon scheduling procedure for SWRO desalination plant under uncertain freshwater demand

    The rescheduling problem of seawater reverse osmosis (SWRO) desalination plant under uncertain freshwater demand is studied. A rescheduling model of this problem is built, which is a bi-objective optimization with criterions of efficiency and stability. A rolling horizon scheduling (RHS) procedure is used to solve this problem. The framework of RHS is structured. A differential evolution (DE) algorithm is used to compute the solution, and its steps are described. The simulation results of a large-scale SWRO desalination plant with fluctuations in freshwater demand show that the performance of RHS is satisfied.

  • Novel nanomaterials for water desalination technology

    Water desalination has a central role to play in the global challenge for sustainable water supply in the 21<sup>st</sup> century. But while the membranes employed in reverse osmosis (RO) have benefited from substantial improvements over the past 25 years, several recent advances in materials suggest that new membranes with dramatically higher water permeability will become available in the future. After providing an overview of the importance of membranes for sustainable water production, we describe some of the most exciting novel approaches for water desalination based on nanomaterials. In particular, graphene, a single-layer sheet of carbon with remarkable mechanical and electronic properties, can be patterned with nanometer-sized pores, to act as an ultra-thin filtration membrane. Drawing from our group's research at MIT, we will share some of our key findings about the potential impact of nanomaterials as membranes for water desalination in the 21<sup>st</sup> century.
