Why Pre-Filtration and Good Cartridge Filtration is Important

Why Pre-Filtration and Good Cartridge Filtration is Important Membrane element protection matters Removal of solids to protect against membrane fouling: Prefiltration, including both cartridge and depth filtration, alongside RO membranes themselves, are key units in ensuring effective performances in RO units. By removing suspended particulates, colloids and larger color causing organics (NOM) from the feed [...]

Introduction to Water Filtration – Part 5

Introduction to Water Filtration - Part 5 In-Line Clarification In-line clarification is the elimination of suspended solids through the extension of in-line coagulant accompanied by accelerated filtration. This process is known as contact filtration or in-line filtration. This method eliminates suspended solids without the use of sedimentation basins. There are two different approaches in which [...]

Introduction to Water Filtration – Part 3

Introduction to Water Filtration - Part 3 Automatic Gravity Filters Many manufacturers have developed gravity filters that are automatically backwashed at a preset head loss. Head loss, water level being above media, motivates a backwash siphon and pulls wash water from storage up through the bed and out the siphon pipe to waste. A low [...]

Introduction to Water Filtration – Part 4

Introduction to Water Filtration - Part 4 Upflow Filters Upflow units utilize a single filter component for filtration, usually graded sand. The filter works with the finer sand at the top of the bed while the coarser sand resides at the bottom of the unit. Gravel is retained by fixed grids at the bottom of [...]

Applying Quality Methods to Water Treatment

Applying Quality Methods to Water Treatment Water treatment systems can function and work in a wide variety, which is why applying quality methods to water treatment is so important. Water make up is continually changing.  The source of the water directly effects the amount and how quickly the change in the system happens. Having changes [...]

Types of Boiler System Failures

Types of Boiler System Failures Deaerator Cracking One of the more common types of boiler system failures is deaerator cracking. In several deaerators, cracks can develop at welds and in heat-affected areas near the welds. Most often, this occurs at the head-to-shell weld below the water level in the storage compartment. It can also happen [...]
