Continuous improvement The range of DynaSand filters is under constant development and includes the latest developments of sand filters, such as material that is extremely resistant to the abrasions caused by sand that is in constant motion during normal operation. The advanced materials mean less maintenance and prolong equipment life. Additionally, you can optimise the sand cleaning rate (the sand/water ratio) with the help of two adjustable weirs with a specially designed wash box, which minimises losses when backwashing. Uninterrupted operation Uninterrupted operation provides several benefits over conventional backwashing sand filters. In conventional sand filters particles are collected in the sand bed with increasing pressure drop as a result, until finally the sand must be cleaned by backwashing before treatment can proceed. The time between backwashes can be very short, which reduces the effective operating time. It was not until the continuous sand filter technology of DynaSand was developed that it was possible to get an optimal solution to the need for continuous water and waste water treatment process while delivering a constant quality of the filtrate even at a high surface load. Strengths DynaSand improves the process • no first filtrate – always high-quality clean filtrate • simple treatment of wash water, no shock loads • handles high levels of suspended particles without requiring pre-treatment • low pressure drop • low energy consumption • low monitoring and maintenance costs • no need to stop for backwashing • small footprint
