Aqueous Solutions products

High quality water can be produced from brackish, seawater and contaminated sources reliably and on a scale ranging from a few thousand litres per day to many millions.

Deep bed high efficiency zeolite media systems automatically backflush using a microprocessor-based control capable of removing particles down to nominally three micron. A subsequent cartridge filter system can then provide filtration levels down to 0.5 micron, ideal for industries requiring sediment free water supply.

If the feed water contains suspended colloidal or solid particles, as is typical in surface waters, Aqueous Solutions will design and supply a pre coagulation and flocculation system – a mini water treatment plant that supplies crystal clear drinking water quality water after the filtration plant. The Aqueous Solutions lamella plate clarifier is ideal for clarification of pre-coagulated streams. The operating plant footprint is substantially reduced as is capex compared to conventional clarification systems.

Ultrafiltration is a membrane process that separates colloidal or solid material, emulsified oils, microbiological materials, and large organic molecules. It is different from microfiltration and nanofiltration primarily in the size of the molecules it retains. The range of separation is generally 10,000 to > 80,000 molecular weight. Common applications of microfiltration include the removal and recovery of oils, surfactants and paints from waste streams, clarification of wines and juices, and polishing of ultra pure water for bacteria and particle removal.

Nanofiltration membrane technology separates solution to the molecular level. It rejects various larger-size organics, including dyes and sugars, and also has a strong rejection of divalent ions over monovalent ions. Nanofiltration generally uses spiral wound membranes configured in a similar design as reverse osmosis. Some applications include partial softening of feed water, removal of contaminants from water or acid streams, and pretreatment for reverse osmosis or other high purity systems.

High iron content in ground water is a common problem in irrigation projects. Blocked sprinklers, clogged drippers and supply lines, and toxic levels of iron affecting plant growth are all common symptoms of high iron content. Often the iron is in soluble form (clearwater iron) as it exits the bore only to slowly precipitate out throughout the whole distribution network. Normal filtration systems do not effectively remove this form of iron.

Aqueous Solutions specialises in adapting its technologies to containerised plant delivery solutions.
