Water softeners fact sheet
What is hard water? According to a recent U.S. Geological Survey, 85 percent of the United States’ geography has hard water. Hard water is water that contains certain naturally occurring minerals, particularly magnesium and calcium. Hard water causes many problems in a home, including deposits in sinks and bathtubs and gummed-up pipes in home plumbing systems and water-using appliances. ...

Innovative Solutions for Decentralized Wastewater Treatment
Chlorination and UV light are currently the most common methods used for disinfection of wastewater. While these processes are generally well-adapted to community or municipal installations, their operation and maintenance needs present some limitations to assure sustainable performance at the level of individual wastewater treatment systems. As reported in many papers (U.S. EPA. 1999), use of ...

Identification of indispensable components for a better drinking water quality management: Tunis case of study
In order to reduce the number of operations for the assessment of potable water treatment, principal component analysis and hierarchical clustering are applied to large databases of raw and treated water of three treatment plants with various processes. It appears that the measurements can be divided into three clear groups, with a correlation higher than 0.8. The first contains salinity, ...

Environmental toxicity and radioactivity assessment of a titanium processing residue with potential for environmental use
Thorough examination of the physico‐chemical characteristics of a Ti processing residue was undertaken including mineralogical, geochemical, and radiochemical characterisation, and an investigation of the environmental toxicity of softwater leachate generated from the residue. Concentrations of most metals measured in the leachate were low; thus, the residue is unlikely to leach high levels of ...

Municipality of Barrows, Manitoba case study
Situated some 500 km north of Winnipeg, the municipality of Barrows is home to about 300 inhabitants. Barrows has a school in the village with close to 100 students. The only available source of water supply for the municipality is an underground spring with a TDS (total dissolved solids) concentration exceeding 1900 mg/L making the water undrinkable (see Table I). At the request of John Brittain ...

Wastewater Treatment & Recycle
Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

Scalewatcher reduces car wash salt useage from 700lbs a week to 500lbs a year
The Star Car Wash in Trussville, Alabama has dramatically reduced the amount of salt used in its water softeners from around 700 pounds per week to a diminutive 500 pounds per year following the installation of the computerized, electronic, water-conditioner Scalewatcher® from Scalewatcher North America. This has not only saved the company thousands of dollars a year in salt but also ...

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), ...

Controlling Scale Deposition and Industrial Fouling
It costs US industry billions of dollars a year to control and remove the limescale that builds up in industrial equipment such a heat exchangers, evaporative coolers, boilers, chillers and other water fed equipment. Oil wells, for example, face significant scaling problems from the highly mineralized water that are extracted with the oil. Limescale not only increases downtime, maintenance costs ...

Controlling scale deposits in the pulp & paper industry
The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product. As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water and ...

Electronic Water Treatment - An alternative solution to removing beerstone and limescale
Beer contains 90% water and is the most important ingredient in determining its flavor. Water contains calcium and is the most important mineral to the brewing process. The levels of calcium in local water have determined the type of beer produced. The different types of beer whether a light lager or a porter are for the most part due to the water profiles of the areas that made the styles ...
