〔アルミナ源の添加+水溶液化法〕
(1)液体状で供給される市販のアルミン酸ソーダ(NaAlO2)を使用する方法
(2)次に示すアルミナ源に苛性ソーダを加え、水溶液化する方法
・γアルミナ
・カオリンAl2O3・2SiO2・2H2O

・モンモリロナイトNa0.3(Al,Mg)2(Si,Al)4O10(OH)2・xH2O
・アロフェン(Al2O3)(SiO2)1.32.5(H2O)
・水酸化アルミニウムAl(OH)3
(1)ガラス微粉末に発泡剤とゼオライト化前駆物質を混合した後、焼成する方法(以下、「手法1」と称す。図1参照。)
(2)ガラス微粉末にゼオライト化前駆物質を混合しゼオライト化させた後、発泡剤を混合し、焼成する方法(以下、「手法2」と称す。図2参照。)
(3)ガラス微粉末に発泡剤を混合焼成し発泡ガラスを製造した後、ゼオライト化前駆物質を付着させ、マイクロ波によりゼオライト化する方法(以下、「手法3」と称す。図3参照。)
間隙率(吸水率)Q(%)=(mS−mD)/mD×100
但し、mS:試料の質量(g)、mD:乾燥後の試料の質量(g)である。
図4において、本実施例の水域直接浄化システムは、最上流側の粒径の大きい、例えば、粒径80〜100mmのゼオライト化発泡ガラス90から順に粒径の小さな、例えば、それぞれ粒径60〜70mmおよび30〜40mmのゼオライト化発泡ガラス91,92を接触材として接触槽内に充填したものである。特に、第1槽、第2槽の接触槽は目詰まりを起こしやすい箇所であるため、粒径を大きくし、容積充填率を60〜80%とすかすかの状態(例えば、第1槽を60%、第2槽を70〜80%)としておく。
