Description

The Filtration Process

  • Raw water enters through the filter’s inlet and passes first through the pleated coarse screen which catches large debris and sediment. The unique pleated design of the coarse screen provides a larger screen area, increasing the filter’s capability to handle high dirt loads of large particles. The water then continues to flow through the filter and passes through the inner fine screen which catches the remaining smaller particles.

The Control System - Amiad’s NEW ADI-P Controller

  • Amiad’s ADI-P controller offers a one-of-a-kind monitoring and control functionality. The controller interacts with Amiad’s advanced, user-friendly app that provides detailed filtration performance data on your mobile phone device.The self-cleaning mechanism is controlled and monitored by the ADI-P controller. The self-cleaning cycle is triggered by an integrated DP switch.

  • The ADI-P controller and mobile app also provide:

  • brightness_1DP and flush cycle counters

  • brightness_1Alerts – low/high pressures, low battery

  • brightness_1Reports and performance history data

The Self-Cleaning Process

  • The self-cleaning cycle is initiated by any one of the following conditions:

  • brightness_1Signal from the DP switch, pre-set at 7 psi (0.5 bar)

  • brightness_1Time interval parameter set at the controller

  • brightness_1Manual start, triggered by the ADI-P mobile app (within Bluetooth range) or via electronic controller keypad

  • brightness_1Flushing duration set with the ADI-P app

  • The flush valve opens to atmosphere creating a strong suction force at the scanner nozzles, effectively removing dirt particles from the screen and discharging them from the filter
