The Clean Water Solution

Drinking water

Clean water solutions from Sunstone Water • Clean Water Unit • 1 – 200 m3/h • Drinking water according to WHO standards • Can produce drinking water from the following sources:

- Ground water - Surface water - Brackish water - Sea water - Pre-treated wastewater

The Clean Water Solution

Electrical control system. A complete integrated control system. It provides full automation with as little operator intervention as possible.

Ozonation Disinfection and initial break-up of organic material is done by injecting Ozone in to the feed water.

CIP system A complete CIP (Cleaning In Place) system that can be used with the UF systems.

Reverse Osmosis System A complete Reverse Osmosis system for the reduction of salinity to acceptable drinking water levels meeting WHO standards and current EU directives.

Activated Carbon Filtration The GAC after the UF filter removes small organic molecules, medications, chlorine, pollutants and toxins, as well as many other types of chemical elements and compounds from the water.

Ceramic Membrane Ultra-filtration (UF) system Our ceramic membranes are used to separate solids and dissolved macromolecules, eliminate viruses and bacteria, retain the fermented biomass and remove particulate chemical oxygen demand (COD).

Climate-controlled container All components are mounted in a single patented 40-foot container. Climate control ensures optimal operational conditions. The patented frame allows for easy mounting of components, ensures safety in shipping and easy access during maintenance

Pre-filter Oxidation Process UV system Ultrafiltration Active Carbon RO System

Components: • Air supply: Produces high quality oxygen from ambient air • Ozone: Oxidation of organic and inorganic matter • Ultraviolet (UV) system: Works as catalyser in the oxidation process • Retention tanks: Ensures optimum ozone reaction time • Active Carbon (GAC) : Completes the oxidizing cycle and removal of

dissolved molecules • Reverse Osmoses pre-filtration: Prevents carbon residue downstream • Reverse Osmoses: Pressurized flow of different solute concentrations

across a membrane • Final adjustment of water quality (e.g. pH or minerals) according to

requirements

Technical footprint

Cornerstones in our drinking water solutions:

• Sunstone Water delivers High-End solutions • We prioritize trouble-free operation and best in class Life Cycle Costs • We only use components of best available quality • When we say mobile, we mean in. 100% containerized and plug&play • We use climatized and insulated containers in order to secure the best working conditions • Possible to operate the unit remotely using 3G mobile access • The unit can be powered by generators, wind or solar – besides from normal power grid • Storage tanks in container available – secure water supply by gravitation • SmartGrid control is possible – treat and move water when energy is cheap or free • Plant can be delivered with bottling machine and/or user payment system

The Clean Water Solution

STW Water, in conjunction with Sunstone Water Group, has introduced Sunstone’s patented modular wastewater treatment system to the State of Texas. STW, in conjunction with Sunstone is performing a pilot project, subject to the oversight of the Texas Commission on Environmental Quality (TCEQ), with one of the major cities in Texas. The purpose is to demonstrate and show the efficiency of the system and to also gain acceptance and approval for use commercially in municipalities. STW, with its manufacturing partner Sunstone Water Group, also has the technology to reclaim municipal wastewater to potable reuse standards. It is specifically referred to as: Municipal Reclaimed “NEW” Water (formerly "Toilet-to-Tap”). STW’s Reclaimed “NEW” Water systems for reclaimed wastewater with its advanced pre-treatment process combined with Hybrid high brackish high recovery or Seawater Reverse Osmosis System is capable of purifying contaminated water with a variety of complex water qualities thereby preventing fouling attacks on membranes & allowing reliable operation with significantly reduced operating expenses and decreased power consumption.

Latest reference project: Full scale Pilot Project in Texas, USA
