WATERQUBE WATERQUBE SYSTEM OVERVIEW THE WATERQUBE IS A CONTAINERIZED, CLEAN ENERGY, CHEMICAL FREE WATER TREATMENT SYSTEM CAPABLE OF SUPPLYING 10,000 – 20,000 LITRES OF CLEAN WATER PER DAY FROM CONTAMINATED WATER SOURCES. SECONDARY FILTRATION: NANOMESH Carbon Nanotube (“CNT”) technology is about manipulating carbon atoms at a microscopic scale. Nanotechnology generally refers to the scientific application of knowledge to manipulate and develop structures with dimensions in the range of 1 billionth of a metre (one nanometer) to 50 billionths of a meter. FEATURES •Solar powered, containerized clean water system •Pre-clean with 25 and 5 micron bag and activated carbon filtration for sediment and organic removal •10,000 litres per day tank capacity •Post-clean with Seldon double stage nanofiltration CNTs are the core of Seldon NanomeshTM technology and have a diameter ranging from sub-nanometer up to approximately 50 nanometers. They are forms of carbon which have a cylindrical wall structure (coaxial for multiwalled-CNTs) and resemble a continuous, seamless hexagonal lattice of carbon atoms. The length of CNTs is typically thousands to tens-of-thousands of nanometers with a few special carbon nanotubes grown to longer than one million nanometers (1 millimeter). CNTs have intrinsically superior electrical and mechanical properties compared to other materials, and their very large aspects ratios (width to length) and tensile strength make them the ideal fiber for fluid filtration if applied in a stable and suitable form. NanomeshTM is made up of a fused nanostructured, non-woven material that is produced in a readily scalable process combining functionalized CNTs, activated carbon and fibers within a supporting substrate sheet material. Using the enormous surface area created by the CNT-based nanomesh, it combines size-exclusion filtration and advanced sorption capability, resulting in a simple, flowthrough filter that maximizes purification at low pressure drop. •Solar powered LORENTZ submersible pump for water harvest with float and 50 metres hose •Remote monitoring for filter replacement, water volume, pump status. OPTIONS •Water quality monitoring •Residual chlorine for ancillary water storage •Battery for 24/7 water usage •External Solar Light BENEFITS •Filter and cartridges and carbon changes only – no added chemicals •No requirement for power supply •LORENTZ pumps are Oxfam approved and represented internationally.

Bags are replaced when incoming pressure increases indicating excessive blockage. 2 Activated Carbon is commonly used to absorb natural organic compounds, taste and odour compounds, and synthetic organic chemicals in drinking water treatment. Activated carbon is an effective absorbent because it is a highly porous material and provides a large surface area to which contaminants may absorb. One of the main types of activated carbon used in water treatment applications is granular activated carbon (GAC). 2 1 WATERQUBE SOLAR PUMPS PRIMARY FILTRATION PS SURFACE SOLAR WATER DISTRIBUTION PUMP PS HELICAL ROTOR WATER HARVEST PUMPS PUMP SYSTEMS PS150 BOOST PS200 HR PS600 HR PS1200 HR PS1800 HR PS4000 HR MAX.

This increase in pressure indicates the bag are progressively blocking from the collection of sediment from the water source. The frequency of bag changes will be dependent on the quality of the water source and the filtration of the bags selected (50um, 25um, 5um, 1um). The Filter Bag Pressure will be measured and monitored by the Water Harvest Pump Controller. Activated Carbon will not block but will eventually fail to absorb the natural organic compounds present in the water source. This can be detected by water quality measurement of the Activated Carbon can be replaced at set, periodic intervals. The Activated Carbon is replaced by removing the canisters, opening and replacing the contents. NanomeshTM are nominally rated at 60,000 litres capacity but will last for longer with effective Primary Filtration. The Nanomesh is installed in a bank of five parallel units and assuming full daily use of the WateQube, should be replaced monthly by swapping Nanomesh cartridges. 15 Roxburgh Avenue Lonsdale SA 5160 1300 552 040 [email protected] reaqua.com.au
