轉貼 RC 的.
前期, 由FRAG仔養起  
簡單沙缸




sera siporax 環


出KZ色, 超低營養環境

nickdo

後期, 假石, 無沙, 用白色亞加力做底

有無落碳源先

梗係無啦.

Ching 可否講下有乜設備，眼見咁乾淨和同設備都好簡單咁

一眼見晒, 簡單清爽

滴定都無, 用石灰水做埋自動補水, 淨係每星期換水, 都幾啱城市人.

之前有 totm 三年無換水添。

養角啵，

我記得果隻缸, 但D色其實好差下. 玩到咁無意思.

呢隻缸係用環呢過濾, 而呢隻SERA環睇網頁係可以行硝化同反硝化作用(去NO3). 所以先可以有超低營養KZ色.
老實講, 就算用其他方法要去到超低營養都唔係易. 仲有好多野要take care.

唔知呢隻環係咪真係咁勁.

有提到 Siporax 的用法是 - 每 100L 用 0.2L Siporax.

巴西果邊好多人咁玩的. 好似話資源貧乏, 玩咸野好貴.

白色底佢話一個星期刷一次. 無沙環境可以吹到一粒魚屎都無咁濟. 個落水口又對準化氮(唔用綿/袋), 個上水泵又經閘制有條喉吹沙缸, 成個缸/沙缸真係 0 積屎.

Simultaneous nitrification and denitrification using Siporax™ packing

Abstract
In this paper, we examine a biofilm process for simultaneous removal of ammonia and NOx (nitrite and nitrate). Siporax™, a porous Raschig-ring type filter specifically designed and manufactured for fast colonisation by micro-organisms, was used to demonstrate the feasibility of simultaneous nitrification (usually an aerobic process) and denitrification (usually an anaerobic or anoxic process) inside a single reactor. Clear evidence was found that denitrification occurred inside the internal pore structure of Siporax ™rather than in an anoxic zone near the outlet of the reactor. The reactor was operated continuously and maximum nitrification and denitrification capacities of 0.61 and 0.83 g N/(1.day), respectively were observed in this study.

反硝化>硝化, 這就意味著反硝化NO3的速度大於硝化NH4的速度. 就是可以做到NO3=0.
