The “rotten egg” odor in some water supplies is caused by sulfide in water. Sulfide can be treated using oxidation techniques, the goal being to convert the sulfide to high oxidation state species such as sulfate to eliminate the taste and odor concerns. Traditional oxidation techniques such as ozone and chlorine can be used, but can be expensive due to the equipment required to add and monitor the oxidant, and can lead to by-products such as trihalomethanes (THMs), which are regulated in drinking water supplies.
Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Two new particle detecting technologies have been developed to help optimize filter performance at water treatment plants (WTP).
Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
