Sand and Dust control/stabilisation

by Technical Absorbents     based in Grimsby, UNITED KINGDOM

PermeatecDS is a unique polymer technology developed by TAL and is aimed specifically at the control of dust and stabilisation of loose, granular materials. PermeatecDS can be applied to such materials – as an aqueous surface spray – to control dust and provide a hard, durable surface. In addition, it can be mixed directly with loose, granular material to provide a solid block of material. PermeatecDS is a complex acrylate-based polymer system, designed to be dispersed in water, aiding application and improving safety/handling. The polymer is able to coat and bind loose materials, forming a complex web of interlocking particles and polymer, which – when dried – form a hard, durable material. The ability to change application rates, provides the user with precise control and allows stabilisation levels, strength and durability to be tailored as required.

Liquid Rock - Prevening Scale Formation from Ground Water Hardness

by WAT Australia Pty.Ltd.     based in West Australia, AUSTRALIA

Groundwater is in contact with soil and rock minerals. Significant amounts of the minerals are dissolved in the groundwater. Elevated water hardness is the result of the water interaction and partial dissolution of carbonate minerals. Scale formation is a crystallisation process. Crystals are a highly organised arrangement of molecules. The determining circumstances for a successful crystallisation event include concentration, temperature, pressure and chemical environment. Suitable conditions for the formation of a crystal require numerous factors to coincide. CALSTAT RO-30 provides crystallisation interference at a molecular level :  Excellent results are achieved at low trace quantities of product. Calstat RO-30 dosed at trace levels of 4-10 kg per million litres  Corrosion on steel surfaces is reduced or eliminated  For drinking water production with RO (reverse osmosis) systems, membrane fouling is reduced. The water additive

Electrodeionization

by QUA Group LLC     based in Canonsburg, PENNSYLVANIA (USA)

The Fractional Electrodeionization (FEDI) process is an advancement of conventional EDI. The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant& design economics and reliability. By incorporating a two-stage separation process with different voltages the FEDI process is able to: Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus reducing the potential of hardness scaling. Optimize power consumption by using higher electrical current only where required. Ensure the best water quality, continuously consistently by removing a major part of the deionization load in the hardness removal zone, while residual ionic impurities are effectively removed in the silica removal zone;, which stays in a polishing mode.

Water Containment

by Manas Geo Tech India Pvt. Ltd.     based in New Delhi, INDIA

Polymeric liners are prone to puncture by inclusions within the underlying soil. Thick, non-woven geotextile can be used to give protection to liners during installation. Often the upper slopes are exposed to damage and it is a good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete substance can be used to achieve a hard landscaped appearance. Our product will protect the liner from puncture whilst also providing a degree of slope stability.

Crushing of salts with Mercodor crushing systems

by MERCODOR GmbH Sondermaschinenbau KG     based in Frankfurt am Main, GERMANY

The crushing of salts such as, for example, hardness salts, salt dispensers, but also rock salt, is a great challenge for the crushing machine from various points of view. On the one hand, the salts are very hard, but already in the presence of a very small amount of a liquid they dissolve and mix with the liquid. The Mercodor crushers are best suitable for crushing of salts of any kind such as, for example, crushing of rock salts, but also for crushing of salt dispensers and hardness salts.

Phosphonate Testing in Hard Water

by WAT Australia Pty.Ltd.     based in West Australia, AUSTRALIA

Testing phosphonates in hard water can be difficult due to interference from high levels of calcium. Here we present a phosphonate test method for hard water samples. The method is based on a chemical masking of the calcium. The WAT hard water phosphonate test uses C30 Spectrophotometer to measure the chromogen PMB and digital thermoreactor to digest the phosphonate compound. The thermoreactor capacity of 16 simultaneous vials provides for running critical data quality assurance samples.

Industrial water softening

by PuriTech Ltd     based in Herentals, BELGIUM

The presence of certain metal ions in water causes a variety of problems. These ions interfere with the action of soaps, lead to build up of limescale, which can foul plumbing, boilers, heating equipment. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water extends the lifetime of plumbing and heating equipment. Softening of low TDS ( Total Dissolved Solids ) water is done commonly with a Strong Acid Cation ( SAC ) exchange resin operating in the sodium form and regenerated with brine. PuriTech`s latest development is a very performant continuous ion exchanger, based on PuriTech`s innovative ION-IX technology which is based on true counter-current ion exchange.

Wastewater treatment for the textile sector

by Aguambiente     based in La Cistérniga, SPAIN

The kind of waste water from tanneries has a high salt content that can be diluted, but is hard to eliminate. They can also have a high organic load due to the high dirtiness, including blood, sand and manure. The water itself from these industries can vary a lot from a company to another depending on its actividad. However, a common characteristic is the high content of materials in suspension due to fibres and precipitated proteins.

Industrial water boiler feed water

by PuriTech Ltd     based in Herentals, BELGIUM

Ion exchange is an effective, versatile means of conditioning boiler feedwater. The term “ion exchange` describes the process : as water flows through a bed of ion exchange material, undesirable ions are removed and replaced with less objectionable ones. For example, in softening processes, calcium and magnesium ions(hardness) are exchanged for sodium ions. In dealkalization, the ions contributing to alkalinity(carbonate, bicarbonate, etc.) are removed and replaced with chloride ions.

Pumps for Isocyanate

by DESMI A/S     based in Noerresundby, DENMARK

Isocyanate is one of the components in broadly all foam products such as foam mattresses, inner linings in cars, cushioning in car seats, chairs and sofas. The hard qualities are used for insulation of houses, machines, tubes, etc. There are various types of isocyanate, but common to all of them is that they react to the humidity of the air by forming very hard crystals, which wear out the pumps and mechanical seals, if any. For MDI (Isocyanate) it is recommended to use positive displacement pumps and the leading MDI producers are recommending the DESMI ROTAN® series (magdrive pumps). They have been successfully used for a long period of time at many different applications.

Mold Control

by AgriAir Equipment     based in Mukilteo, WASHINGTON (USA)

Controlling mold spores and bio-contaminants is a challenge for indoor gardeners that requires attention to detail and specialized equipment. An average cubic foot of air has around 100,000 mold spores. When sufficient moisture is available, mold grows. AgriAir Purifiers control and eliminate Aspergillus and many other types of spores, mildew, odors, and VOC as well as sanitize the air and hard surfaces from biological contaminants generated by organic decay during the entire growing process. AgriAir Purifiers generate ionized-hydro-peroxides, which result in a proactive method of indoor air sanitation and promote organic garden production. This purification method eliminates the need for the use of additional chemicals or biocides that generally contain toxic compounds. AgriAir products can safely be used in occupied spaces throughout the entire grow cycle all while effectively destroying mold spores and other harmful bio-contaminants.
