Juntai Provides Technical Calculations for Bar Screens

Chinese company Hangzhou Juntai Plastic Products Co., Ltd. has released a technical calculation guide for the design and dimensioning of bar screens. This technical document is intended for professionals in industrial and wastewater treatment sectors, providing a basis for equipment selection and performance assurance.

The guide addresses key aspects including the selection of appropriate bar screen types, determining channel width, managing flow velocities, and estimating the quantity of screenings collected. Juntai emphasizes that these calculations are crucial for ensuring efficient wastewater treatment and optimizing equipment performance.

Central to the calculations are factors such as the dimensions of the screen bars and the gaps between them, the screen's inclination angle, and the velocity of water flow through the channel. The company has specified different gap sizes for coarse, medium, and fine screening needs, ranging from 50-100mm down to 3-10mm.

Furthermore, the calculations account for head loss across the screen, which can increase due to accumulated debris. Juntai utilizes a 'clogging coefficient' to estimate this additional head loss, helping to ensure system functionality under varying operational conditions.
