Different research show aloe properties for coagulation in water treatment
The polysaccharides of aloe and chitosan passed different test methods that demonstrate their coagulant function.
In different investigations, the results indicate that both aloe and chitosan have excellent coagulation effects, achieving an effective adsorption of the main heavy metals, including cadmium, copper, chromium, mercury, lead and arsenic.
One research – Application of Natural Product (Aloe Vera) in Coagulation-Flocculation Procedures for Water treatability Study – describes aloe gel has shown good performance in all trials due to the great versatility of its composition, which helps both in the coagulation process as in the flocculation process.
The aloe vera solution as a coagulant allowed a 40% reduction of aluminum sulphate in samples of high turbidity, achieving a removal of more than 95% of the turbidity. The practical application of aloe was studied by the Pontifical Bolivarian University of Bucaramanga, Colombia.
The study – Removal of Heavy Metals from Wastewater Using Chitosan – shows that the high porosity of this natural polymer confers excellent properties to trap ions of metals such as cadmium, copper, lead, uranium, chromium and mercury.
The report Adsorption of Hexavalent Chromium from Aqueous Solutions by Aloe Vera Leaf demonstrates the good results for the adsorption of chromium when aloe vera is used.
By other side, the research Chitosan research as a coagulant during the treatment of oil production waters published by the University of Zulia, Venezuela, demonstrates the excellent results in the use of chitosan for the treatment of wastewater in the oil industry, with levels of Turbidity removal greater than 90%.
The study Application of Aloe Vera in Coagulation and Flocculation Procedures for Water Treatment offers interesting results on the use of aloe for coagulation and flocculation in contaminated waters.
The document Aloe sp. leaf gel and water glass for municipal wastewater sludge treatment and odour removal also explains the use of aloe vera in coagulation and flocculation process for municipal wastewater.
The research “Use of Aloe Vera Gel as a Coagulant” also shows the good results obtained when aloe vera is used for coagulation.

In conclusion, the biological treatment seems to be the most reliable method for the disposal of pollutants in many industries.
Example 1: the aloe option is a sustainable and environmentally friendly way to treat the millions of gallons of waster water generated by the hydraulic fracturing job.
