With the increasing scarcity of clean water and growing popularity of rainwater harvesting, potable rainwater use is inevitable. It is often the cleanest feedstock for the production of drinking water, since it has fewer contaminants than surface water or groundwater in most cases. The main concern with making rainwater potable is the possibility that harmful microbes could be present.
From traditional to cutting edge, rainwater disinfection technologies abound
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.

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.
Providing the right solution at a good value while maintaining profit margins
Over the years, the term “environmentalism” has morphed through various phases and subcategories, creating a whole new paradigm that confuses most of the general population. To the average person, terms such as environmentalism, “environmentally friendly,” “sustainable” and “green” seem to be used interchangeably. The director of the Green Business League, Michael Richmond, described the muddled understanding of these terms as “that ugly green color that we made in kindergarten when we slurred all the colors into one big blob.”
Sorting through environmental terminology
Industrial fluid processing operations can face a number of serious problems due to bacterial biofilms. Biofilm-induced corrosion, mechanical blockages and impedance of heat transfer processes result in huge monetary losses each year. In engineered systems, additional risks of biofilm-mediated contamination include negative public health consequences and product spoilage. This article addresses aspects of biofilm control strategies for industrial processes and introduces a promising disinfectant.
Overview of Biofilms
Effectively controlling tough biofilms
Al Lozier, CWS-VI, CI, CSR, learned the ropes of a running a successful water dealership from the ground up. He began selling residential filtration systems in 1988, and when his employer offered him the opportunity to start a satellite office the following year, Lozier gladly accepted. The result: Fresh KC Water, Shawnee, Kan.
“We wanted to be the different water treatment dealer—Water Quality Assn. trained, approaching the customer from the service side instead of the sales side and offering products that fit the customer, not the dealership,” Lozier said.

Simply sit back and listen to hear the widespread cries for the government to assist nearly every type of business. This is especially applicable to those industries with significant funds available for local and/or federal campaign contributions. Nearly every segment of our economy is subsidized in some way by our tax dollars, or more accurately with borrowed dollars.
The role of government in the water treatment industry
The past year has presented challenges, but looking back, everyone in the water treatment industry can be proud of what they contributed.
