The Aquaphor APRO WH 1000 LPH is a professional reverse osmosis water purification system designed for various applications. This system is equipped with fully automated control, utilizing a logic controller, water level, and pressure sensors to supply purified water based on an adjustable algorithm. It is suitable for a range of configurations and can be integrated with auxiliary equipment.

Function Description:

The APRO WH 1000 LPH system is designed to produce purified water through reverse osmosis. It includes several key components and functionalities:

Feed Pump (P-03): Boosts pressure and supplies water to the reverse osmosis membranes.
Recirculation Pump (P-05): Concentrates permeate through the osmotic membranes.
Dosing Pump (DP-01): Doses antiscalant to prevent scaling.
Feed Valve (XV-01): Controls the supply of feed water to the reverse osmosis system.
Concentrate Valve (XV-04): Manages concentrate drainage.
Permeate Drainage Valve (XV-02): Drains permeate.
Permeate Flushing Valve (XV-05): Flushes membranes with permeate during standby.
Supply Pump (P-04): Supplies RO permeate to the user.
Pretreatment Backwashing Switch (PTS-01): Indicates the pretreatment backwashing stage.
Low Level Sensors (LLS-01, LLS-03): Protect pumps from dry running.
High Level Float Switches (HFS-01/02): Mechanically block water supply when tanks are overfilled.
Pressure Switches (LPS-01, LPS-02, HPS-01, HPS-02): Monitor low and high pressure conditions in various parts of the system to protect components and ensure proper operation.
Flow Sensors (FT-01, FT-02): Measure permeate and feed flow.
Conductivity Sensors (ECT-01, ECT-02): Measure permeate and raw water conductivity.
Control Panel: Provides an interface for system operation, configuration, and monitoring. It includes an emergency stop button, reset button, RO system mode switcher (OFF, AUTO, CIP), alarm indicator, and run indicator.

Usage Features:

Automated Control: The system operates with fully automated control, minimizing the need for manual intervention.
Control Panel Interface: The control panel allows users to start/stop the system, reset programs, switch between operating modes (OFF, AUTO, CIP), and view alarms and operational status.
Configuration: The system can be configured via the controller keyboard, allowing adjustments to various parameters such as start-up flush time, shut-down flush time, standby flush period, and alarm setpoints for conductivity and pressure.
System Start-Up and Shut-Down: The manual details step-by-step procedures for system start-up, including checking feed pressure, valve opening, and pump activation, as well as shut-down procedures involving pump deactivation and valve closing.
System Run Display: During operation, the control panel displays current parameters such as permeate conductivity, flow rates (permeate, concentrate, feed), recovery percentage, temperatures, and pressures (feed, inlet, RO, permeate).
Cartridge Display: Shows remaining cartridge resource and pressure drop, with an alarm for replacement.
APRO Android App: Allows remote monitoring and control of the system via a mobile device, including data transfer, program setup, parameter monitoring, log viewing, statistics, and alarm display.
Modbus Communication: The system supports Modbus RTU communication for collecting system information, allowing integration with external control systems.

Maintenance Features:

Dosing Pump Degassing: Instructions are provided for degassing the dosing pump after antiscalant replacement, involving turning off water supply, opening the deaeration valve, and then closing it.
Membrane Module Replacement: Emphasizes ensuring correct installation direction (arrow on the module) when replacing membrane modules. The unit should be recommissioned after replacement.
Filter Cartridge Replacement (Viking Cartridge): Detailed steps are provided for replacing the filter cartridge, including turning off water supply, relieving pressure, unscrewing coupling nuts, removing the old filter, cleaning components, installing a new filter, and reassembling the system.
Yearly Check and Maintenance:
- Cables and Cable Connection: Periodic checks for wear, fissures, damages, and corrosion are recommended. Electrical work should only be carried out by competent staff after ensuring power absence.
- Automatic Concentrate Valve Flush Opening: Regular checks for proper functioning of the concentrate valve.
Membrane Cleaning (CIP): A comprehensive procedure for cleaning the membranes using a CIP kit is outlined, involving preparing a cleaning solution, filling the CIP tank, switching to CIP mode, flushing with raw water, and then circulating the cleaning solution.
Calibration: Periodic calibration of conductivity sensors is required, typically after cleaning. This involves multipoint calibration using standard solutions (1413 mkS, 84 mkS) and air (0 mkS), ensuring sensors show correct values and replacing them if necessary.
Preservation of RO and NF Systems: Instructions for preserving the system during shut-down periods longer than 48 hours to prevent biological growth. This involves immersing elements in a bisulfite solution, venting air, and periodically checking pH and replacing the solution.
Troubleshooting and Alarms: The manual lists various alarms (e.g., low raw water level, pretreatment system error, high permeate conductivity, low flow) with their possible causes and corrective actions, including manual resets, checking components, and performing CIP or membrane changes.
Warnings: Provides warnings for situations such as end of cartridge resource or high pressure drop, prompting users to replace cartridges and reset the system.
