Abstract (en)
[origin: EP0805246A1] Process to operate a swimming pool filter unit depending upon the current load. The unit pumps water leaving the pool with a pump driven by an electric motor, whose rotation speed is adjustable, via at least one filter device (5) and back to the pool. The water level in the container (3) is recorded by sensors (6) as a measure of the number of bathers in the pool (1), then processed (7) and fed to a process computer (8). Here, the value is used along with other process variables such as water loss, fresh water feed, water run off, pump and filter coefficients, to obtain a control value to regulate the frequency re-set (9). This affects the required water flow rate via the filter pump (4), found by the equation: Qhreg=RxQh100. Also claimed is a device to carry out the above process.
