Sodium Aluminate(NaAlO2) is a chemical, manufactured by S² in Israel using a unique recycling process.QualityProduct specifications meets the standards of AWWA and of EU authorities.The specifications of each batch are controlled by an authorized laboratory.AdvantagesLiquid coagulant having the highest concentration of active element on the market. The aluminum content is 11-12%.Cheapest coagulant (based on concentration of active element).Availability of the product assured (local supply).Sodium Aluminate is a basic coagulant (pH > 13.5). Therefore its use, in the case of acidic wastewaters, lowers the cost of the treatment and limits the salinity of the wastewaterHeavy metals removal using Sodium Aluminate occurs at pH = 6-7 whereas with other existing chemical treatments, pH should be at least 10.The use of Sodium Aluminate and Alum for coagulation, combined with pH control, lowers the cost of treatment and limits the wastewater salinity.Main UsesThe product is widely used as coagulant in chemical treatment of urban & industrial wastewater. It could also be used for the treatment of drinking water and the pretreatment of seawater for desalination.Additional Uses Pulp and paper industries: retention filler, anionic trash collector, sizingCement additive for setting accelerationPigment coating for paintsManufacture of catalystsProduction of Zeolites (detergents) 

Potassium Aluminate (KAlO2) is a chemical, manufactured by S² in Israel. QualityProduct purity meets the most stringent standards of AWWA and of EU authorities.The specifications of each batch are controlled by an authorized laboratory.AdvantagesReplaces Sodium Aluminate for applications in regions with Sodium sensitivity.Potassium Aluminate is a basic coagulant (pH > 13.5). Therefore its use, in the case of acidic wastewaters, lowers the cost of the treatment compared to the use of other coagulant requiring pH correction with KOH.Liquid coagulant having the highest concentration of active element on the market. The aluminum content is 11-12%.Heavy metals removal using Sodium Aluminate occurs at pH = 6-7 whereas with other existing chemical treatments, pH should be at least 10.DisadvantagesThe use of Potassium ions makes the product expensive 

Alum or Aluminum Sulfate Sulfate (Al2(SO4)3) is a chemical marketed by S².QualityProduct purity meets the most stringent standards of AWWA and of EU authorities and is authorized for the use of drinking water treatment.The product is KosherThe specifications of each batch are controlled by an authorized laboratory.AdvantagesS² developed a process of manufacturing it using recycling technology. Alum is a liquid containing around 4% Al. It can be readily used for waste water treatment.Alum is used as an acidic coagulant in combination with Sodium and Potassium Aluminate to maintain a controlled pH level of the treated waste water.DisadvantagesIt is more expensive than Sodium Aluminate unless recycled product is usedAcidic coagulant could reduce the pH below 6 and cause odor problems. It has then to be used with caustic soda pH correction
