Default meneruskan kesinambungan thread RAS - Rumah Ais Saya.
~bissmillahirrahmarnirrahim~

Salam bros semua, kepada yang baru join BJ (macam saya) ini adalah kesinambungan thread artikel RAS



RAS - Rumah AIS saya



Byk org debat tentang makna RAS ni yang selalu di dengar ;

1. Recycled Aquaculture Systems.
2. Recirculating Aquaculture Systems.

so basically penjelasan ia sebenarnya ialah seseorang itu mengambil langkah;

1. Naik turun basikal Semula atas Tangki Ikan
2. Pusing keliling Semula sekitar Tangki ikan.

acah je...

(RAS air Masin SAHAJA kalau RAS air tawar mungkin bros lain leh bagi pendapat.)

RAS bermakna Recirculating Aquaculture system. Definasi RAS - Recycled Aquaculture Systems itu sebenarnya more to Sewage treatment atau perawatan air.

System RAS ader 2 Type;

PRAS - Partial Reuse Aquaculture Systems
1. Partial Reuse Aquaculture Systems - PRAS - ini hanya 10% RAS.
Sistem guna tukaran air berjadual. ader 2 type Sistem PRAS ni;

a. Sistem dimana air dialirkan "SEROUND jer" sebelum di "exchage"(di tukar)
b. Sistem dimana air dialirkan "10 round atau lebih" sebelum di "exchage"(di tukar)

sebab utama exchage sumber air di buat kerana bahan byproducts sudah berada di tahap berbahaya. maknernya enviroment air tak sesuai lagi untk penternakan.

RAS
2.Recirculating Aquaculture Systems - Ini Adalah RAS 100%
System yang 100% airnya di guna pakai semula. Ini adalah system yang SANGAT berbeza dari Sytem 1. Ia melibatkan complexity dan rawatan air yang intensive.

a. System ni menggunakan 100% air yang dirawat semula.
b. Melibatkan equipment tambahan yang di gunakan merawat air secara intensif.
c. Strategi penggunaan air di ambil kira utk provide balances perternakan dan memaximun haverst dan kualiti sambil mengurangkan risiko. Design ras di kira total loading waste supaya loading waste boleh di rawat at least 120%.
d. main culprit HANCUSS untk system ni adalah phosporus dan Nitrate (NO3) yang selalunya menyebabkan system ni overloaded dan air terpaksa exchange at least 10% akibat overloading byproducts Phosporus dan NO3. Phospuros dan NO3 ni sebenar hanya 3% dari total load waste tapi bila dah terkumpul lamer -ie; 6 bln dan takder system yang efficient/designed utk implemented spesific buamg utk product ni.(ada caranya cuma org takmo kasi tau)

BRO BRO YANG OTAI


marilah kita bincangkan supaya dapat ilmu ni di turunkan utk dapat membantu kawan2 mendapatkan sesuap nasik dan bawang dapur meraka. semoga usaha anda di rahmati ALLAH.

wallahuallam.

INI ADALAH RAS SAYA - yang atas tank tu ubat ubatan yg dh expired!
