Electroosmotic Pump Using a Glass Fiber Filter for High Flow Rate Water Transport

Electroosmotic pump does not need moving mechanical parts, which can be fabricated by micromachining process and integrated with other micro-devices. Electroosmotic pump is the hydraulic actuator component and can be used in HPLC (High Pressure Liquid Chromatography), μTAS (Micro totally analysis system), chip test system, micro cooling system and micro drug delivery system, etc. The paper is to design an electroosmotic pump with low driving voltage, high pressure and high flow rate, and fabricate the samples of cascaded open-channel direct current electroosmotic pump. The three-dimensional model of one-stage parallel open-channel electroosmotic pump is established by finite element analysis software of CoventorWare. The numerical simulation of the electroosmotic pump performance has been done by CoventorWare. Compared with the equivalent circuit model, the results show that the cascaded open-channel direct current electroosmotic pump has the advantages of high flow rate and high pressure.

Water Piping

A conventional design of rainwater harvesting system collects and directs the rainwater through water piping from roof of building to the water storage. The filtration system which locates before the water tank storage and first flush bypass system is the main focus of the research. A filtration system consists of a control volume of filter compartment, filter screen (stainless steel mesh) and water piping that direct the water flow. The filtration efficiency of an existing filter “3P Volume Filter VF1” by industrial company is enhanced. A full scale filter design prototype with filter screen of 1000 μm stainless steel metal mesh is tested to compare with the original filter system design. Three types of water inlet setups are tested. Among the proposed water inlet setups, the 90° inlet setup with extension provides the best filtration rate per unit time, following by the 45° inlet setup. The 45° and 90° inlet setup has similar filtration efficiency at low to medium flow rate while 45° inlet setup has better efficiency at high flow rate. The filtration efficiency with the 90° inlet setup with extension is observed to maintain at highest value at medium to high flow rate. The overall filtration performance achieved by the 90° inlet setup with extension at low to high flow rate is between 34.1 to 35.7%.
