The Aqua-Nu ceramic membrane is designed for both business-to-business (B2B) and business-to-consumer (B2C) Applications with far-reaching commercial and humanitarian value and performance in both the home and the local community of the developed and developing worlds.

The Aqua-Nu Ultra High Flow Rate Ceramic which has an adjustable flow-rate and pore value is capable of being manufactured to ANY SIZE.

This unique point-of-use filtration technology is the result of six years research and development, testing and evaluation by Aqua-Nu scientists into non-chemical based ‘Ultra High Flow Rate Ceramic’ and original anti-microbial treatment systems.

We are now seeking commercial partners to help us bring this exciting technology to market and fulfill our vision of delivering strong environmental benefits as well as helping alleviate the impending water crisis.

Municipal and Industrial Water Treatment Systems

Water treatment describes those processes used to make water more acceptable for a desired end-use. These can include use as drinking water, industrial processes, medical and many other uses. The goal of all water treatment process is to remove existing contaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use. One such use is returning water that has been used back into the natural environment without adverse ecological impact.

The processes involved in treating water for drinking purpose may be solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation. Biological processes are also employed in the treatment of wastewater and these processes may include, for example, aerated lagoons, activated sludge or slow sand filters.

Aeration Treatment Systems

Aeration is more than the supply of oxygen and mixing. Aeration is the cornerstone of biological wastewater treatment and controls the treatment performance and operational economics of the entire wastewater treatment facility. Analysis of wastewater treatment plant costs repeatedly shows that aeration accounts for 50 to 80% of the overall plant-operating budget. Without the right aeration technology and a properly designed aeration system, treatment performance and plant operating cost objectives cannot be attained.

Reverse Osmosis (RO) or DeSal Treatment Systems

Reverse osmosis (RO) is a membrane technical filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective,” this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.

Rainwater Harvesting Systems

Rainwater harvesting is the accumulating and storing of rainwater for reuse before it reaches the aquifer. It has been used to provide drinking water, water for livestock, water for irrigation, as well as other typical uses. Rainwater collected from the roofs of houses and local institutions can make an important contribution to the availability of drinking water. It can supplement the subsoil water level and increase urban greenery. Water collected from the ground, sometimes from areas which are especially prepared for this purpose, is called Stormwater harvesting. In some cases, rainwater may be the only available, or economical, water source.

Rainwater harvesting systems can be simple to construct from inexpensive local materials, and are potentially successful in most habitable locations. Roof rainwater can’t be of good quality and may require treatment before consumption. As rainwater rushes from your roof it may carry pollutants, such as mercury from coal burning buildings, or bird feces. Although some rooftop materials may produce rainwater that would be harmful to human health as drinking water, it can be useful in flushing toilets, washing clothes, watering the garden and washing cars; these uses alone halve the amount of water used by a typical home. Household rainfall catchment systems are appropriate in areas with an average rainfall greater than 200 mm (7.9 in) per year, and no other accessible water sources (Skinner and Cotton, 1992). Overflow from rainwater harvesting tank systems can be used to refill aquifers in a process called groundwater recharge; though this is a related process, it must not be confused with rainwater harvesting.

There are several types of systems to harvest rainwater, ranging from very simple home systems to complex industrial systems. The rate at which water can be collected from either system is dependent on the plan area of the system, its efficiency, and the intensity of rainfall (i.e. annual precipitation (mm per annum) x square meter of catchment area = litres per annum yield) So, for example, a 200 square meter roof catchment catching 1,000mm PA yields 200 kLPA.

Aqua-Nu is currenlty developing a full line of ceramic membrane products that will assist systems and equipment manufacturers to deliver high value, cost effective aeration solutions for even the most challenging applications.
