A water treatment method could comprise of a number of mechanisms to achieve its objective. Thus, a filtration mechanism is part of a whole system or method by which the ultimate objective is achieved. Undisputably, a single mechanism may also be water treatment method depending on the contaminants of the available water.

Unbalance charges are offset by exchanged cations adsorbed on layer surfaces. However, those exchanged cations easily hydrate to form a thin water film. Adsorption of nonionic organic matters from effluent to bentonite is relatively weak due to preferential attraction of polar water molecules to polar mineral surface [14], [15].

Granular bentonite for water treatment. Coagulent for water treatment. ENVIRO-SEAL 12 and 30 are natural, granular sodium bentonite (clay) that have exceptionally low permeability and high swelling capacity. They work well as a coagulant for wastewater treatment and has a high affinity for cationic contaminants.

The raw bentonite was washed by soaking in ultra-pure water for 10 min and thereafter draining the wash. The level of the ultrapure water used was such that it covered the entire sample in the beaker and was allowed to overflow. The procedure was repeated four times. The washed bentonite was dried in an oven (24 h at 105 °C).
