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

7. 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

14. 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
