“…Ceramic water filtration is the process of passing water through a porous ceramic material. It is a promising way to reduce the burden of water-borne diseases; it is affordable in terms of cost and made from local resources [2]. It has been shown that ceramic filters can reduce turbidity [3] and microorganism [2].…”

It has been shown that ceramic filters can reduce turbidity [3] and microorganism [2]. Meanwhile, physico-chemical properties of ceramic filters such as porosity and chemical stability are important to evaluate the filter efficiency.…”

This paper deals with the characterisation and study of physico-chemical stability of ceramic filters from clays and rice husk obtained from the far north region of Cameroon (Logone Valley) and their application in potable water treatment. Clays from Mouka were characterized by FTIR analysis. The results showed that the filter formulated with a mixture containing 80% clay and 20% rice husk of 100 μm in size each gave the lowest filter shrinkage rate; these formulated filters were chosen for the remaining work. Leaching tests showed that with filters at a sintering temperature of 830˚C the leaching was not observed under neutral (pH 6.8) and acidic (pH 5) conditions as compared to 950˚C and 1000˚C where the leaching was observed. In basic (pH 9) condition, all the filters obtained released ions. Leaching tests revealed that the conductivity of the leachate for the filters sintered at 830˚C was lower than those sintered at 950˚C and 1000˚C. Meanwhile, conductivity decreases with increasing sintering temperature (temperature up to 830˚C) due to the fact that ceramization starts as from 850˚C that leads to an amorphous state that favours chemical stability, the leaching ions were Fe 2+ , Ca 2+ , Mg 2+ and Al 3+. The ceramic filters sintered at 950˚C were applied to the filtration of water and the performance in terms of turbidity reduction was 95% and the flow rate after 50 minutes was 100 × 10 −3 L/h.

“…A mixture of the most effective and stable is a pottery strainer rice husk mixture with the composition of the main ingredients of clay and rice husk 80% and 20% [12]. The ceramic filter with 15 % saw dust, 80 % clay and 5 % grog that was fired at temperature of 950 °C or 1000 °C showed the best removal efficiency [10]. Tests showed that copper is a suitable antibacterial agent to combat coliforms in contaminated water.…”

Efforts to create a filter alternative in an emergency is very necessary in order to meet the drinking water needs. Filter pottery is one alternative screening models are cheap and mobility, so it can be applied, however, the ability of pottery on filtering raw water into drinking water needs to explored.. This study tested the ability to pottery from a mixture of clay and fine rice husk with 0.001 mole added of silver nitrate and 0.0005 mole within the period of use. This study conducted in soil and water engineering laboratory, Universitas Padjadjaran, Environmental Laboratory Institute of Ecology Universitas Padjadjaran and Energy and Mineral Resources Laboratory, West Java Province. This study also conducted pore size analysis using Scanning electron microscope (SEM) in order to know the pore diameter and pore distribution formed from the ceramic pot filter. The faucal-coli analysis is performed as an indicator of filter quality generated from the ceramic pot filter. The results showed that added of silver nitrate to lower the flow rate of 0:35 l/h. The Increasing added of silver nitrate also showed an increase in water resulting residue 0:02. Increasing the number of used periods to decrease of silver nitrate residue 0001. The results show that ceramic pot filter can reduce the number of e-coli with significant amount. The size of the pores of ceramic pots formed shows a diameter smaller than the diameter of e-coli. There are still some cracks in the process of making ceramic pots, thereby reducing the ability of ceramic pot filters to reduce e-coli.Keywords-ceramic water filter pot; e-coli residue; silver nitrate residue; number of applied.

“…al., 2018, andJassim, et., al., 2013). Its properties can be controlled by developing technology to meet certain purposes (Zereffa, Bekalo, 2017) . The pore size of the ceramic material can be made homogeneous and small within the range of microfiltration ( Jassim, 2010), which is excellent to remove most of the suspended solids and bacteria (Nurmiyanto, Prasetya, 2012).…”

In this study, contaminated water was purified by ceramic purifieres produced from a mixture of Iraqi raw materials. These raw materials were activated kaolinite, Porcelanite, and Limestone. They were mixed with two different mixing pertcentages to produce two types of ceramic (AKP1 and AKP2). Ceramic filters were evaluated based on anumber of parameters that were: hydraulic conductivity, purified water properties, and adsorption ability. Results indicated that ceramics hydraulic conductivity have values 0.0024, and 0.0032 m/hr, respectively. The filtered water were tested for water quality parameters that the ceramic filters could remove, as an average percentages of removal, 99.9% to 3.26% by AKP1 and 100% to 64.67% by AKP2. The adsorption ability of the ceramics for solutes of seven heavy metals, Mn, Fe, Pb, Cd, Co, Cu and Zn, were measured. Results showed that most of the heavy metals ions were removed by the both types of filters that the removal varies between 98.18 and 100% of the initial concentration of each metal. The adsorption capacities of each filter to adsorb the heavy metals were computed according to Langmuir model and Freundlich models. The results showed The data were most fitted to Freundlich model.
