Municipalities and their Engineers often ask why they need to design and invest in a degasification system as part of their water treatment facility. What are the problems and cost advantages that degasification will help you overcome?
Degasification is the most cost effective means of providing higher quality water and lowering your operational cost. The proper use of degasification will drastically lower chemical consumption, lower your TSS (total suspended solids) in your treated final water, prolong the life of your equipment by eliminating the formation of corrosive conditions, sulfur, and sulfur bacteria in your downstream conveyance and distribution systems. Here are 4 ways that a degasification system can solve your water problems:
1. Produce Higher Quality Water
The use of degasification to remove H2S or to reduce CO2 levels eliminates the need to add additional chlorine, or Caustic to the final product water. By eliminating the need to add chemicals to oxidize Hydrogen Sulfide (H2S) and by stripping the H2S from the water with degasification the final product water has a lower total suspended solids level (TSS) with a higher quality of taste for the consumer. The CO2 removal eliminates the need to add Caustic Soda to lower the pH after membrane treatment to re-establish a neutral pH level. The elimination of the addition of Caustic improves water quality and alkalinity of the water.
2. Protects Equipment and Distribution Systems
Water with very high concentrations of Hydrogen Sulfide (H2S) whether in a dissolved gaseous state or still in a solid form is a threat to your water treatment equipment and the downstream distribution system. Hydrogen Sulfide can convert and produce Sulfuric Acid and will lower the pH in the water or at the point of reaction. Gases like carbon dioxide that also lower the pH can form carbonic acid which is another type of corrosive acid that can cause corrosion in equipment, pumps, and pipes. If high levels of H2S and CO2 are left in the product water other equipment downstream of the distribution system can be damaged. For the residential consumer water pipes, water heaters, pumps, underground distribution pipes in neighborhoods all have a high potential of experiencing corrosion from these two chemicals. For industrial process plants or food processing plants H2S and CO2 can damage items like distribution pipes, pumps, membranes, boilers, and other types of commercial equipment. Degasification of the water will help protect your equipment and render the water safe for use.
3. Protects Users
Degasification of water will help get rid of harmful gases. Water contaminated with gases has a number of negative health effects and is dangerous when consumed in higher concentrations. Exposure to Hydrogen Sulfide (H2S) should be avoided at all times as it is lethal. Consuming higher dosages of chlorine also has a negative impact on your health. And with high levels of H2S and other organics Trihalomethane (THM) is a known carcinogenic and it can and will form in the downstream water storage or distribution system in the presence of organics and Chlorine. The production of THM’s should be avoided at all times to reduce negative health impacts. Degasification to remove H2S and lower the amount of organic loading in the water to remove the H2S will render it safe for use and consumption.
4. Economically Efficient
Degasification is the most cost effective solution to remove H2S, CO2, or to oxidize Iron. By incorporating a degasification system into the final product water to remove H2S, CO2 or Iron the operational cost of the treatment facility is drastically lowered by the reduction in Chemicals consumed. In addition the water quality is improved, the equipment life is extended, and the protection to the consumer is increased. The use of a degasification system will also help reduce capital costs by reducing the capital expenses associated with replacing damaged equipment or assets.
