Worldwide, engineered plastic connectors and tubing are used in the water quality industry for a host of residential, commercial and industrial applications. From water treatment and filtration to beverage dispensing and ice making, there are several sound reasons for their widespread use.

Activated carbon is commonly used in point-of-use (POU) and point-of-entry (POE) water applications. Activated carbon is predominantly used to remove organic-based contaminants and inorganic contaminants like free chlorine and monochloramine from water. Other water treatment processes such as reverse osmosis or ion exchange are better suited for other inorganic chemicals that may be present in water.
Factors impacting contaminant removal
Elevated levels of arsenic, iron and manganese prompted Brandywine Elementary School in Greenfield, Ind., a small town just east of Indianapolis, to seek a treatment solution for the school’s drinking water. The water system is served by one well that provides drinking water for approximately 330 students in kindergarten to fifth grade.
In July 2009, Ladd Eng. Inc. contacted AdEdge Technologies Inc. to provide a proposal for the Brandywine Elementary School in the Southern Hancock School District.

Arsenic and its compounds have been known to be toxic for millennia. Arsenic trioxide (As2O3), often referred to as white arsenic, was a favored poison in the Middle Ages because it had little odor or taste, enabling it to be easily incorporated into the food or drink of a victim. As little as 300 mg can be fatal to an average person.
Solutions to an age-old threat
As its traditional ion exchange process grew more expensive for perchlorate treatment, the West Valley Water District (WVWD) sought change with a new bioremediation plant. Assistant General Manager Thomas J. Crowley, P.E., recently discussed making the switch with WQP Managing Editor Rebecca Wilhelm.

I am sure many of you have seen the flood of recent headlines and articles posted all over newspapers, the Web and every news channel across the nation. The headlines are grim:
Getting to the bottom of a hot-button issue
Giving customers value is what most retailers and wholesalers are doing during the economic slump. With rising costs for products and shipping, it is difficult to maintain sales and acquire profits. Cutting costs without cutting corners can be difficult as well. Sizing a water system and applying the correct treatment system can be a daunting task because salespeople must take into consideration that the customer wants the best possible water treatment at the lowest possible cost.
