• System is enclosed in a sturdy, durable, ISO certified ocean shipping container for easy transport via trailer, tractor-trailer or cargo ship

• System can be deployed and pumping purified water in less than 15 minutes with full setup in less than 3 hours

• All of the components of the MWPS-4000 are transported fully self-contained within the box which can be secured with a heavy duty lock or security seal

• Full training provided at IWC's facility or available with in-country installation onsite

• Rugged, one horsepower, self-priming, submersible pump can be used in a variety of water sources

• Ultrafiltration provides low turbidity water and a barrier to bacteria, even in changing water conditions

• Disinfects water without the use of chemicals

• On-board reservoir and electronic dosing pump support residual post-treatment disinfection for water storage, electrolytic injection for cholera control, or liquid fertilizer for drip irrigation.

• Parallel and redundant treatment systems allow for continuous production during backwash and maintenance activities

• Automated backwash function ensures timely cleaning extending filter life and substantially reducing labor costs

• Factory set backwash intervals may be re-programmed according to source water quality

A look inside the self-contained MWPS-4000

• No replaceable filter cartridges; membranes can be used for several years with minimal maintenance

• Polishing filters can be optionally customized based on specific water challenges

• Fully integrated hybrid power management system allows for use of included solar and wind power, as well as on-board generator and AC or DC external line power ensuring that on-board battery bank is continually charged.

• On-board, 3 kilowatt generator automatically starts to power and charge the system when it detects low battery levels.

• Electronic water conditioners provide:

– Corrosion resistance

– Scale inhibition

– In-line coagulation, which increases filter efficiency and decreases filter fouling

• UV final stage disinfection effective against bacteria, viruses, and protozoa

• Removes arsenic III/V, lead, mercury, chromium VI, copper and uranium
