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%.

Abstract Background Non-intubated video-assisted thoracic surgery is a therapeutic option for intractable secondary spontaneous pneumothorax in patients who are poor candidates for surgery with endotracheal intubation under general anesthesia. However, intraoperative respiratory management in this surgery is often challenging because of hypoxia caused by surgical pneumothorax. Case presentation A 75-year-old man with idiopathic pulmonary fibrosis who had been on home oxygen therapy underwent non-intubated uniportal video-assisted thoracic surgery for intractable spontaneous pneumothorax. During the operation, oxygen was administered using a high-flow nasal cannula at a high flow rate. An air-locking port for single-incision surgery was used to minimize the inflow of air into the pleural cavity. The intrapleural air was continuously suctioned through the chest tube. The air-leak point was easily identified and closed using ligation. Oxygenation was satisfactory throughout the operation. Conclusions Non-intubated uniportal video-assisted thoracic surgery for secondary spontaneous pneumothorax with an air-locking port, continuous pleural suction, and high-flow nasal cannula may achieve satisfactory intraoperative oxygenation in patients with respiratory dysfunction. The intrapleural space can be feasible for surgical manipulation without surgical pneumothorax in non-intubated video-assisted thoracic surgery even when supplied with oxygen at a high flow rate using a high-flow nasal cannula.
