Strong Acid Cation As mentioned previously, the strong acid cation unit contains a zeolite resin that is regenerated with sulfuric acid (HCI can also be used, but it is more expensive than H2SO4). As the untreated water passes through the strong acid cation unit, the hydrogen ions that occupy the exchange sites in the resin […]
Strong Base Anion Anion Removal is a strong base anion resin removes the anions associated with the weak acids in the effluent from a strong acid cation unit. Specifically, strong base anions remove silica (from H2SiO3) and carbon dioxide from H2CO3 (carbonic acid). In addition, the strong base anion resin removes anions associated with the strong […]
Demineralization Process In many process boiler systems, zeolite softening of water is not sufficient to meet feed water quality standards. In these cases (typically high-pressure boilers up;1000 PSIG), the water is demineralized. This process removes most of the mineral content of the raw water. Demineralizers depend upon both cationic and anionic exchange processes. They can […]
Sakagami seal Bagian yang tak kalah pentingnya dalam sebuah sistem baik pada Cylinder hydraulic maupun Cylinder pneumatic adalah sealkit yang terdapat dalam cylinder. Sebagaimana pada bagian cylinder Seal Kit juga terdiri dari beberapa bagian yaitu Piston Seal, Rod Seal, Dust Seal atau Wiper dan O-ring yang merupakan penghubung antara bagaian-bagian cylinder. Sakagami seal Seal hydraulic cukup banyak sekali bentuknya sesuai dengan fungsinya serta bahan yang digunakan juga bermacam-macam dari bahan yang […]
Definisi Air Limbah Air limbah adalah air yang telah mengalami penurunan kualitas karena pengaruh manusia. Air limbah perkotaan biasanya dialirkan di saluran air kombinasi atau saluran sanitasi, dan diolah di fasilitas pengolahan air limbah atau septic tank. Air limbah yang telah diolah dbuang/dialirkan ke badan air penerima melalui saluran pengeluaran. Air limbah, terutama limbah perkotaan, […]
