Reverse Osmosis-A walk in time

Posted by Anthony DeLoach, President on Aug 21, 2018 8:53:00 AM

DeLoach Industries made history in 1977 at the City of Cape Coral Florida water treatment plant with its large scale “degasification towers” connected to what was to become the first municipal water treatment facility in the United States to deploy the use of reverse osmosis on a large-scale production municipal treatment plant.

The Cape Coral water treatment plant for came on line in 1977 and produced 3 million gallons of water per day (GPD) or 11.35 liters of purified and treated water utilizing the “reverse osmosis” process. By 1985 the plant had expanded as it kept up with growth to produce 15 million gallons per day making it at the time the worlds’ largest “reverse osmosis” water treatment plant facility.

Industrial Odor Control: The Do’s and Don’ts

Avoiding problems with calcium chlorite, corrosive gasses with your odor control scrubber.

When planning or designing an odor control system one should pay close attention to several key variables that can cause havoc on a chemical odor control scrubber when trying to treat hydrogen sulfide or ammonia gases.   The need for odor control occurs for many different forms and it is important to have a good understanding of the process that is creating the odorous or corrosive gas and the need for the odor control & air emissions treatment.

First begin to identify

all the potential obstacles that may creep up later after the chemical odor or corrosive gas control system goes on line like acid or caustic consumption. As an example, chemical odor control systems that are designed for water treatment for the municipal industry are typically needed and attached to a degasfication or decarbonation process which are often needed to treat hydrogen sulfide (H2S). However, many times designers may not pay close enough attention to the type of water process that is available to use for “make-up” water for the chemical scrubber and with the addition of caustic this can create scaling or fouling. This unknown variable of the make up water quality can lead to a complete tower shutdown if the chemical scrubber distribution and media bed scales or fouls. The most commonly used chemicals for a hydrogen sulfide (H2S) scrubber are either chlorine in the form of sodium hypochlorite or caustic in the form of caustic soda. Both of these chemicals are both common to a water treatment facility and already in place for the adjustment and control of pH.

Don't Foul Your Chemical Odor Control Treatment System.

When operating a chemical odor control treatment system it is important to make sure you have a good handle on the makeup water supply system in terms of its water quality. Having the LSI number out of balance can create havoc to the odor control treatment system in a matter of hours or over a short duration of time.
