Catalytic hard water scale prevention system saves thousands of dollars
The Western Technology Center in Oklahoma was experiencing ongoing scaling issues in their cafeteria building requiring costly planned maintenance and chemical use. Six Rinnai tankless water heaters had to be descaled every month with the cleaning process requiring most of one day. The heaters are fitted with keypads that flash a “descale required” code when necessary. In ...

Method for an accelerated reproducible calcite-layering of potable water systems to validate decalcification procedures
This article describes a method for an accelerated, controlled and reproducible build-up of limescale in potable water systems. The concept of this method is to systematically generate water with a high calcium carbonate precipitation potential (CCPP) by CO2-enrichment, hardening with CaCO3 followed by CO2-desorption. Water with a CCPP of about 100 mg/L CaCO3 led to the intended calcification ...

Case study - Preventing scaling saves expensive pigging operations and production shut downs
UK Based Fluid Dynamics has won a contract to supply its non chemical environment friendly hard water scale prevention products to prevent scaling in an effluent stream. The problem: backwash from iron filters, softeners and RO units combined to block drain lines and cause pumps to seize at a major UK government establishment in Oxfordshire England. The only way to clear these drains was to ...

Case study - US school saves almost $50,000 eliminating water softeners
In Texas, Even though properly maintained, a conventional salt based water softener at Fort Bend ISD (Independent School District) had proven to be ineffective at preventing scale. This resulted in scaling throughout the system particularly in the kitchen / cafeteria area. The main Hobart dishwashing equipment had to be opened up and descaled every week taking up staff time and consuming ...

Effective Co2 Removal
CO2 is difficult for both RO and EDI to remove since it has no charge, or is weakly ionized. It is important to remove CO2 in the EDI pretreatment because it will lower the EDI product water quality, will compete with silica for removal, and may lead to scaling of the EDI. Here are 3 ways to remove CO2 effectively in a system: Corosex II absorbant media, prior to the RO Benefits: Passive and ...

Limitation of hardness from thermal water by means of nanofiltration
Geothermal conditions are extremely favourable in Hungary. Thermal water is accessible in 70% of the territory of the country, with a lowest temperature of 30°C. For energetic purposes, it can be utilized in two different ways: for supplying heat or generating electricity. In relation to utilization, one of the most serious problems derives from the chemical composition of thermal ...

Preventing scale in recreational vehicles and motorhomes
Over 80% of North America is affected by hard water, which is a major problem for the owners of RVs and Motorhomes. Consequently, whatever State you are visiting in your RV, or if you have a motorhome permanently located in a hard water area, limescale will clog pipes, ruin appliances, destroy faucets and cloud glassware. The award-winning, patented, Scalewatcher water-conditioner, from ...

Preventing scaling caused by hard water without the use of chemicals ... a unique green technology
Preventing scaling caused by hard water without the need to use chemicals. A unique green technology.Scaling caused by hard water is a worldwide problem it builds up in process systems, heating systems, air condi¬tioning systems and even irrigation systems. Traditional methods to prevent it involve water softening, deminer¬alisation or the addition of chemicals. All of which are expensive and ...

SnowPure Tip: Effective CO2 Removal
CO2 is difficult for both RO and EDI to remove since it has no charge or is weakly ionized. It is important to remove CO2 in the electrodeionization pretreatment because CO2 lowers EDI product water quality, competes with silica for removal, and may lead to scaling of EDI. Here are 3 ways to remove CO2 effectively in a pure water system: Corosex absorbant media, prior to the RO Benefits: ...

Ion ScaleBuster Water Conditioning - Office Building - Case Study
OVERVIEW Following a public tender in 2005 for social housing, ION ScaleBuster® water conditioner was chosen for a pilot as the water treatment required to solve corrosion and scaling problems for all buildings in the headquarters of the CPAM (Caisse Primaire d'Assurance Maladie). WATER SYSTEM CHALLENGES According to the public tender, apart from proven scale and corrosion prevention, the ...

Biodegradable products enhance oil production case study
Kemira’s biodegradable products play an important role in oil production in the North Sea. When seawater is injected into the deposits to move oil toward the drill pipes, it comes into contact with a different type of water: the water under the seabed. These two types of water do not mix well, and the layers of scale that form as a result may damage pipelines and halt production. The ...

Boiler feed water - power generation facility application - Case Study
Challenge A large power generation client required a treatment solution to meet the parameters required for their boiler feed operations. The inlet feed water contained several contaminants including hardness minerals such as calcium/magnesium, dissolved salts, trace hydrocarbon and certain heavy metals including ferric iron. Solution Genesis Water Technologies provided consulting, design and ...

A comprehensive factorial design study of variables affecting CaCO3 scaling under magnetic water treatment
Magnetic water treatment (MWT) could be an interesting alternative to chemical treatment to prevent scaling and has been used as an antiscaling treatment for domestic and industrial equipment. A two level-three factor (23) full factorial design was used to evaluate the effects of pH (6–7.5), flow rate (0.54–0.94) and application of a magnetic field on the induction time (IT), ...

Environment Friendly Treatment Reduces Scaling up of Sugar Plant Evaporators: Saving Money by Reducing Shutowns
Scaling is one of the biggest problems when it comes to processing sugar but recent experience in Ecuador proves the effectiveness of a totally green technology that reduces evaporator scaling dramatically. As raw materials are processed to make sugar one of the main problems encountered is scaling. The areas affected are different in beet factories to cane factories but both suffer from it. ...

It is the law (part L building regs) that in hard water areas a scale preventer must be placed before any new boiler installed
Not many people know that .. to coin a famous phrase, but it reflects the increased cost of energy usage arising as a result of scaling caused by hard water. Traditionally water softeners’ might have been used for this purpose but there are increasing environmental concerns about the use of water softeners .. in parts of California they are now banned. Fluid Dynamics is the UK’s ...

Hyundai Heavy Industries South Korea - Case Study
OVERVIEW The factory uses water for cooling furnace rolls coil cooling systems in their manufacturing process. The water is cooled by cooling towers, stored in tanks and pumped to the rollers as required by temperature controllers of the manufacturing process. WATER SYSTEM CHALLENGES The furnace rolls water coil cooling system got clogged with scale causing downtime and maintenance work. In ...

Research on the synthesis and scale inhibition performance of a new terpolymer scale inhibitor
A new terpolymer named β-CD-MA-SSS was produced using free-radical polymerization of β-cyclodextrin (β-CD), maleic-anhydride (MA) and sodium-styrene-sulfonate (SSS) as monomers, with potassium persulfate (KPS) as initiator. Its performance as a scale inhibitor to prevent deposition of calcium carbonate (CaCO3) has been investigated. Experimental results demonstrated that β-CD-MA-SSS performed ...

Scaling caused by hard water is one of nature’s expensive phenomenons.. But there is a totally natural solution
Scaling caused by hard water is an expensive problem .. not only do significant financial costs arise trying to prevent it or removing the effects of it but in addition there is a huge environmental; cost to many of the treatments used against it.! Water softeners put so much salt into the environment that they are now being banned in some parts of the USA. Chemicals, as we all know, are not ...
