Water & Air Filtration & Treatment 

Water Filtration

Water for Aquaculture

Backwashing

Back washing is undertaken by simply reversing flow flushing out particles trapped in the filter with the liquid then placed on the garden or lawn as it contains no harmful chemicals likely to damage plants. Pressure requirement is much lower than for sand due to the spaces in the media which do not require additional pressure even if run backwards and upwards also water usage is reduced on backwashing. 

Water Treatment 

Bore Water

Bore water requires careful treatment mostly related to the levels of salts contained therein. In times of drought there is a build up of Sodium Chloride which needs to be reduced to be able to be used by people and animals. The other major chemical entities are Calcium and Magnesium, Chloride and Oxide. These require an oxidant treatment usually by ozone to produce insoluble oxides which can be filtered out by the CMZ. 

Stormwater systems going to the environment mandatory require reduction of total Nitrogen and total Phosphorus (TN and TP). CMZ can bind ammonium ion but ZeoChar when appropriately treated can take out anionic molecules with a single reagent. 

Tank Water (rain water or soft water)

Industrial Waste Water

This encompasses all other chemcials from diverse industries and is a specialised area. 

Agriculture

Water for agriculture has a lesser requirement for lower levels of other metallic ions. Transition metal ions can be effectively treated but may require an initial process to change their solubility. The most affective treatment before CMZ is ozone. 

Food Producing Animals & Birds

Animals requires appropriate treatment to allow them to drink adequately to maintain health and fitness. As above heavy metals and some transitional ions need to be reduced particularly in times of drought when the level of salts increases to such an extent that limits animals from drinking. There are at least two or most probably three treatment methods that will be required. Initially sodium ions must to be reduced. 

Potable Water

Potable water requires other treatment in addition to filtration with steriliants. In some places fluoridation is added to reduce tooth decay. 

Desalinated Water

This water is amde by reverse osmosis (RO) and zeolite may be used in the initial filtration and treatment before RO.

Air Filtration

CMZ is very hydrophilic and as such attracts water molecules in water saturated air containing partilces e.g. from diesel exhausts. In situations where the air is vented without water saturation then a mister or fogger can be installed below the filter to generate moisture in the air stream. 

Air Treatment 

Treatment of the air is by reaction with a chemical inclusion to react with malodorous and or poisonous volatiles e.g. oxidants like Chlorine or Peroxide to treat Hydrogen Sulfide (H2S). Mercaptans, Ammonia (NH3) and amines in STP or reductants such as Sodium metabisulfite to treat Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2) and Carbon Monoxide (CO) from road tunnels.

This is the basis of its use in treatment of air in risers in sewage treatment plants (STP).
