A preliminary study on cactus as coagulant in water
Abstract The coagulation performance of cactus to act as natural macromolecular coagulant was studied by the jar test. The cactus coagulation attained comparatively high turbidity removal efficiency, and water with turbidity less than 5NTU could be obtained with initial turbidities from 20 to 200.
For the coagulation-flocculation various tests will be conducted with one hand, the conventional coagulants (Ca2 +, Fe3 + and Al3 +) and, on the other hand, alginate, extract of cactus prickly
A preliminary study on cactus as coagulant in water
The cactus coagulation attained comparatively high turbidity removal efficiency, and water with turbidity less than 5NTU could be obtained with initial turbidities from 20 to 200. When used to treat the same water sample, the optimum dosage of cactus coagulant was found similar to that of AlCl 3 ·6H 2 O. Effects of factors such as pH, temperature, alkalinity on cactus coagulation were also studied.
In a preliminary study, the coagulation performance of cactus as natural macromolecular coagulant was studied using the jar test procedure. Cactuses were collected, washed and dried at 80 • C...
Comparing cactus (Opuntia spp.) and alum as coagulants
A comparative study was performed between cactus (Opuntia spp.) and alum as coagulants. Monthly samples of raw water, delivered from (Al-Mashroo Canal), we The analysis was conducted to decide the optimum dose, optimum velocity gradient, and optimum flocculation time for both coagulants.
In this study, the coagulation ability of cactus powder as a natural coagulant on polluted water treatment was analyzed using jar test and UV-Vis spectroscopy method. It was observed that cactus powder forms large flocs with impurities in the water sample which facilitated settling and resulted in clear supernatant formation.
Cactus Opuntia as natural flocculant for urban wastewater
The cactus tree, species Opuntia ficus-indica, is a primary material of many products in various domains such as cosmetics, medicine and nutrition.In the present work, we assess its potential as a flocculant. We tried a technique which adopts three sequential treatments that used coagulation, flocculation and sedimentation processes under certain operating conditions.
Cactus as coagulant/flocculant for wastewater treatment of cactus pieces in 750 ml of tap water (stirred for 30 minutes). Interestingly, the use of these natural [34]. In contrast, the same process was used as preliminary treatment for cassava meal industrial wastewater (containing 14000 mg/L of COD).
USE OF CACTUS OPUNTIA AS A NATURAL COAGULANT: WATER
Observing the need for clean water and recycling of wastewater through effective treatment to help counter the continued water scarcity facing Kenya, the study sought to explore the possibility of using cactus in the coagulation-flocculation process.
Abstract. A comparative study was performed between cactus (Opuntia spp.) and alum as coagulants. Monthly samples of raw water, delivered from (Al-Mashroo Canal), were studied and analyzed for turbidity removal during the period from August 29, 2014, to July 23, 2015.
Desalination and Water Treatment - Taylor & Francis
AbstractIn this study, the potentiality of Cactus opuntia (ficus-indica), as a coagulant for the treatment of simulated industrial water-based paint wastewater in terms of colour, chemical oxygen demand (COD) and turbidity was investigated. The coagulation ability was assessed for 1 L of effluent using the standard jar test apparatus by varying the operational variables like eluent type (water
The efficiency of using tapioca starch as a natural coagulant on semiconductor wastewater treatment was investigated. The silica content in the wastewater was pH dependent and it was found that the reduction of COD and turbidity occurred at pH between 12 and 14 with measurements below 100 mg/L and 100 NTU respectively.

- How sustainable is Chile's water and sewage system?
- For example, Aguas Andinas is the largest water and sewage utility in Chile that serves around 40 percent of the Chilean population. Chile has achieved 100 percent treatment of its urban wastewater, which is an important step towards sustainability.
- Does Chile have a good water supply?
- Despite the lower availability of water in Chile, the drinking water and sewerage companies have maintained high levels of coverage, continuity of service, and quality standards. Likewise, thanks to the works executed by the private sector, problems due to floods and turbidity events have been avoided.
- How privatized is Chilean urban water production & reuse market?
- Currently, the Chilean urban water production and reuse market is 96 percent privatized. Privatization has enhanced the market’s competitiveness, overall water quality, and contributed to cost reduction as well as continuity to the point where the country now has 100 percent coverage in both drinking water and sanitation in the urban areas.
- Is wastewater a sustainable resource in Chile?
- Chile has achieved 100 percent treatment of its urban wastewater, which is an important step towards sustainability. However, there is an opportunity to further enhance economic resilience by transforming wastewater into a productive resource which is currently underutilized.
