RO unit reverse osmosis water treatment unit

Technical specifications for supply and installation of RO unit reverse osmosis water treatment unit

Requirements of RO unit reverse osmosis water treatment unit

The Desalination that is required is a suitable water treatment plant that can deliver 10,000 litres per hour (10m3/hr).

Treatment Process

The proposed design will consist of the following processes for reverse Osmosis plant (RO)

The RO system produces purified water (permeate) from the feed water via rejection of all organic and inorganic constituents by a semi-permeable membrane system. It separates the incoming feed stream into two effluent streams:

➢ The permeate (treated water) passes through Reverse Osmosis membranes and thus contains greatly reduced quantities of dissolved mineral salts and organics for use (≥ 99% rejection ratio). The designed recovery of your Sea Water RO machine is 30%. This recovery is subject to change with respect to water quality.

➢ The concentrate (reject water) is the stream which passes tangentially across the membrane surface and thus retains the impurities separated from the permeate stream. A certain minimum flow of ‘concentrate’ is necessary to keep the RO membranes from ‘fouling’ due to the removed mineral salts and organic contents.

Tertiary Treatment Stage

This stage will be to condition and disinfect the reverse osmosis permeate water for final use. Treated water from the RO unit shall be chlorinated for disinfection against any possible post contamination. To bring the pH within the World Health Organization guidelines pH adjustment will be done and the treated stored in a treated water tank.

SPECIFICATIONS

Remote monitoring unit is a high specification internet-based system for remote monitoring and control of equipment. It is available as an option with any pump, generator, solar and water treatment installation and provides users with specific information regarding the operation of their equipment. The Remote monitoring unit system is built on modern infrastructure to ensure reliability, speed and accuracy of information.

RTU (Remote Terminal Unit)

The heart of the system is the RTU controller that monitors various selected conditioned signals and relays the data to the Remote monitoring unit Command Center from where such information is disseminated to respective mobile phones and internet applications. The RTU is fitted with a SIM card and so the installation must have a mobile GSM network signal available to operate. It then transmits the data received in selectable communication channels depending on availability.

Remote monitoring unit Command Center

This forms the data terminal for the entire system. Data sent from the various RTUs are received, interpreted, stored and dispatched to various channels. It also issues user generated commands to the RTUs to action on the monitored equipment.

Depending on system specification and fitted sensors, the Remote monitoring unit user is able to see real time equipment operation status, alarms and parameter readings such as:

• Start and Stop.

• Trip due to overload.

• Current and Voltage

• Power supply failure.

• Water flow rate and system pressures (special sensors required)

• Energy consumption (special sensor required)

The user is also able to perform the following:

• Start and stop equipment.

• Schedule equipment operations.

• Report emergency conditions to the Remote monitoring unit Field Service team.

Multi-Platform Mobile Application

An Remote monitoring unit App is available for all popular mobile and computer platforms – Android, iOS, Microsoft (Windows Phone & Windows 10) and Blackberry. The app receives information through automated Push Notifications to the user in real time.

Web Portal

Features a web version of Remote monitoring unit that can be accessed via the internet and provides a dashboard showing graphical data of equipment status and history.

The web portal includes a choice to receive notifications via e-mail regarding the status of the equipment.

SMS Notification

Alerts are delivered on an eventbased frequency via SMS texts to the selected users. SMS is specifically meant for areas with low .

GPRS coverage.

Remote monitoring unit enables equipment operators to improve operating efficiency and monitor system non-conformities that will greatly improve the reliability of water and energy supply, the only running cost being SMS and data bundle charges. The technology is well-proven and reliable and Remote monitoring unit is an invaluable tool that reduces overall system operating costs.
