Penyaring Air Sederhana, Murah dan Mudah
7 Februari 2015
Tips. Air sebagai sumber kehidupan, keperluan kita sehari-hari untuk hidup sehat. Air bersih memang syarat untuk hidup sehat, air kita perlukan untuk keperluan mandi (MCK) dan minum serta memasak. Untuk masyarakat perkotaan biasanya sudah tersedia air kran (ledeng) dari PDAM dan masih ditambah dengan mudahnya membeli air kemasan (air mineral) untuk keperluan minum. Bagi daerah yang jauh dari perkotaan, sumber air masih mengandalkan air sungai, sumur dan rawa. Untuk air rawa, apalagi rawa gambut, mendapatkan air bersih lebih sulit karena air yang bersifat asam (pH rendah). Untuk mengatasi masalah tersebut bisa menggunakan teknologi sederhana, murah dan mudah menggunakan penyaring air dengan bahan yang mudah didapat.
Cara membuat saringan air sederhana:
- Siapkan galon air mineral, buka bagian bawahnya, letakkan posisi mulut galon ke bawah.
- Isilah dengan ijuk setebal 5 cm.
- Lanjutkan dengan mengisi pasir bersih setebal 5 cm.
- Lapisi lagi dengan ijuk setebal 5 cm.
- Lanjutkan dengan mengisi abu gosok setebal 5 cm.
- Lapisi lagi dengan ijuk setebal 5 cm.
- Lapisi lagi denganarang kayu alaban setebal 5 cm.
- Lapisi lagi dengan ijuk setebal 5 cm.
- Terakhir lapisi dengan kapur pertanian, fungsi kapur adalah untuk menurunkan kadar asam dari sumber air rawa gambut.
- Isikan air dari atas pelan-pelan, biarkab air mengalir melalui beberapa lapis saringan sampai keluar pada mulut galon di bagian bawah.
- Tampung air saringan tersebut, air siap digunakan, tentunya dimasak dulu kalau mau dikonsumsi.
Dengan alat ini kita dapat membersihkan air dari kotoran, racun dan dapat menurun pH air dari 3,5 menjadi 7,9.
