Why your Tanks will need a Water Correction
At WaterfromAir we use the Puretec brand Along with their selection of sediment filters, carbon filters and neutralising treatment systems, Puretec offers Tank safe as part of its range in treating rainwater, surface water or underground water. There is a growing need for these as more alternative sources are needed for treating water to make it safe and healthy. Groundwater can be contaminated and the water that condenses out of the clouds soon becomes polluted in the air as it falls on the roof where it is collected and also in the tank where it is stored.
Tanksafe works to kill these organisms or pathogens rendering the water safe to drink. The major advantage of this is it is cheap, easy to apply and monitor, and this remedy does not leave harmful residues. Chlorine by way of contrasting example leaves residue and bad taste with distinct possibility of also forming carcinogenic (cancer causing) compounds. Tanksafe on the other hand is composed of Hydrogen Peroxide and Silver Nitrate. Hydrogen Peroxide is a compound of Hydrogen and Oxygen H2O2 and the Oxygen is what kills the harmful organisms. This means the compound breaks down into water and oxygen. The silver nitrate is well recognised for its extremely low toxicity and is used in combination as it exponentially increases the biocide effect and renders the hydrogen peroxide more stable both in storage and after the disinfection has taken place. Hydrogen peroxide is naturally unstable but with the silver nitrate the product has a 2-year shelf life provided it is stored in a cool, dark spot in an opaque container.
The dosage rates are 1 litre per 16000 litre tank and it needs 24 hours to mix thoroughly and do its work. The disinfection lasts in the tank about 2 months after which time redosing will be needed. Also should there be organic matter in the tank, this will consume the effective oxygen from the product which in return will lower the concentration as observed with the test strips. Obviously additional influx of water will also lower the concentration.
Using Calcite Filters to Correct pH
Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. Calcite corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH which reduces potential leaching of copper, lead and other metals found in typical plumbing systems.
Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted. As the Calciteās calcium carbonate neutralises the water, it will increase hardness and a softener may become necessary after the neutralising filter.
Contact WaterfromAir today to discuss the PH acidity of your rainwater tank as a part of our service we can correct the PH level in your rainwater tank as well as treat the piping system to clean out the remaining sludge in the rainwater tanks pipes. we also offer the service of calcite filters to help minimise and correct the problem of Acidic rainwater build up in your rainwater system.
