Sugar Decolorization

Dalam kehidupan sehari-hari, hampir dipastikan kita membutuhkan gula, baik itu berupa gula pasir untuk dikonsumsi langsung maupun gula industri yang tidak dikonsumsi langsung. Menurut data BPS, konsumsi gula Indonesia tahun 2021 adalah 5.1 juta ton dengan rincian 2.8 juta ton gula kristal putih dan 2.3 juta ton gula industri (rafinasi). Sekitar 1.1 juta ton disuplai…

Sugar Decolorization

In everyday life, it is almost certain that we need sugar, whether it is white crystal sugar for direct consumption or industrial refined crystal sugar that is not consumed directly. According to BPS data, Indonesia’s sugar consumption in 2021 is 5.1 million tons, consist of 2.8 million tons of white crystal sugar and 2.3 million…

Dissolved Air Floatation (DAF)

We often find sea water and river water polluted with oil, especially in areas frequently passed by oil carriers or near jetties. Oil spills will usually spread following the direction of the wind and ocean waves, forming a thin layer on the sea surface. Depending on the temperature, wind speed, tides and water turbulence, the…

Dissolved Air Floatation (DAF)

Sering kali kita menemukan air laut dan air sungai yang tercemar dengan minyak, terutama di wilayah yang sering dilewati kapal-kapal pengangkut minyak atau di dekat jetty. Tumpahan minyak biasanya akan menyebar mengikuti arah angin dan gelombang laut, membentuk lapisan tipis di permukaan laut. Tergantung pada suhu, kecepatan angin, pasang surut dan turbulensi air, lapisan tipis…

Softener System

We have discussed about the Demin Plant in the last article, do you remember? Actually softener is a type of demin plant, namely the Strong Acid Cation (SAC) Exchanger. However, the difference is that the resin softener contains a counter ion of Na+ which has a more specific duty to exchange total hardness or total…

Softener System

Kita telah membahas tentang Demin Plant di artikel yang lalu, masih ingat bukan? Nah softener sebenarnya adalah salah satu jenis demin plant yaitu Strong Acid Cation (SAC) Exchanger. Namun bedanya resin softener berisi counter ion Na+  yang bertugas lebih spesifik untuk bertukar dengan kesadahan total atau total hardness (kation Ca2+ dan Mg2+) di dalam air.…

Condensate Polishing at a glance

Steam Power Plants (PLTU) use steam to drive turbines and generate electricity. Water vapor is obtained by heating the feed water in the boiler with coal as fuel. Water vapor from the boiler is used in the turbine and then enters the condenser to cool its temperature and is referred to as condensate. This condensate…

Sekilas tentang Condensate Polishing

Pembangkit Listrik Tenaga Uap (PLTU) menggunakan uap air (steam) untuk menggerakkan turbin dan menghasilkan listrik. Uap air diperoleh dengan cara memanaskan air umpan di dalam boiler dengan bahan bakar batu bara. Uap air dari boiler tersebut dipakai di turbin dan selanjutnya masuk ke dalam condenser untuk didinginkan suhunya dan disebut sebagai condensate. Condensate ini akan…

Water Treatment Plant (WTP)

Definition Water is a basic human need, whether for drinking, cooking, washing, irrigating rice fields, industrial raw materials, etc. But unfortunately water sources are limited and not all water sources can be directly used for human needs. For example, surface water (rivers and lakes) generally require a filtration process and chemical injection first to remove…

Demin Plant

We have discussed about two desalination methods : Distillation and Reverse Osmosis (RO) in the previous article. Now we will discuss the third desalination method, namely Ion Exchange Demineralization or Demin Plant. What is a Demin Plant? As we know TDS is the amount of dissolved salt in water. The dissolved salts release positive ions…
