I noticed glass bottles in the trash, I thought maybe some partygoer made a mistake. Then I noticed another and another, no mistake. It leaves me wondering, why don't they recycle? Cans, bottles and paper are the most widely recycled products in the nation. Why not there?

The sand screens and micron filters were selected because of the durable and corrosion resistant fiberglass and PVC construction. The specific model of Eden micron filters was chosen to maintain the filter element flux at approximately 3.3 gpm/per 10" equivalent.

What difference can one homeowner make to the environment? Why, when big polluters are making “green” changes, do we need to change our daily living habits? The answer is simple… children! By making slight and easy changes in the way we look at, and treat Planet Earth today, future generations of children will have learned by example.

Traditionally Hydropro has always put the needs of the customer into the forefront of its company philosophy. By doing this, Hydropro has always stayed abreast of the latest advancements in technology in the water treatment field. In this case, mostly because of the remote location (nearly everything, including fuel for the diesel generators, is delivered by ship), the most important customer needs were associated with conserving energy and maintaining reliability.

Previously, the standard Hydropro design for SWRO with energy recovery incorporated a single multistage centrifugal pump (or positive displacement) with a Hydraulic Turbo Booster. This design is fairly simple and generally does not require a significant increase in system controls or instrumentation and is for the most part a sound, and energy efficient SWRO design.

In early 2006 the Carlsbad Pilot plant entered a new phase of testing with the installation of a state-of-the-art seawater desalination system equipped with the latest energy saving technology. The new reverse osmosis system combines two key features that substantially reduce energy use. The first key ingredient is the latest seawater desalination membrane produced by FilmTech (Dow Chemicals).

Storm Water Run-off is a problem in every section of the United States. Learn how to lesson the effect by taking small but effective measures.

The PI report points out two key areas of desalination project impact on the environment: the effect of their high-salinity discharge on aquatic life and the potential impingement and entrainment of plant intake facilities. Although the report claims that safe disposal of plant concentrate is a challenge, it fails to mention that there are over two decades of experience of safe concentrate disposal from both seawater and brackish water desalination plants in the US and worldwide.

The PI report indicates that one of the major reasons for California desalination’s ‘immaturity’ is its lack of affordability. Currently, the cost of desalinating seawater in California is relatively higher than that of traditional low-cost water sources (groundwater and river water) and water reclamation and reuse for irrigation and industrial use.

In June 2006, the Pacific Institute (PI) published a report entitled, Desalination, With a Grain of Salt—A California Perspective. Ignoring several decades of successful track record of desalination in over 120 countries worldwide and the recent groundbreaking advances in applied desalination research in California, the report presents an opinion that most of the ongoing seawater desalination initiatives in the State of California are premature. This opinion is not shared by the people of California, who in the November 2002 state election voted in support of Proposition 50, which endorses the development of an integrated water management plan for the Golden State in which desalination finds its rightful place, along with enhanced water reuse and conservation.
