The Ecomuseum Zoo is home to the most impressive ambassadors of Quebec’s wildlife. All residents of the Ecomuseum Zoo are there for a special reason: orphaned, injured or born under professional human care, each of them could not return to the wild. Hence, they have found a forever home at the zoo.
Many manufacturing processes, analytical measurements, and other industrial processes that involve aqueous solutions are adversely affected by bubbles in the fluid stream. 3M™ Liqui-Cel™ SP Series Membrane Contactors provide a very simple, cost effective solution to help eliminate bubbles from such processes.
ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.
Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants.
Electrodeionization (EDI) is a widely used water treatment process. EDI technology is an electrochemical process that uses ion selective membranes and an electrical current to continuously remove ions from water. The process uses ion exchange resin to remove the ions from the feed stream, producing pure water.
Walnut Valley Water District spans a 29 square mile area in semi‐arid southern California about 20 miles east of Los Angeles. Like many water districts planning for growth amid periodic droughts is challenging and compounded by the need to deliver high quality water throughout the district of over 100,000 people and more than 26,000 service connections. Read the full case study to learn how Walnut Valley aggressively pursued operational strategies in their water storage tanks to limit nitrification risk.
The Francis L. Hatch water filtration plant is in the coastal town in York county Maine and has an average capacity of 2.6 MGD. This is a surface water plant that utilizes hydrated or “slaked” lime (calcium hydroxide) to maintain the pH level around 7.0. For over 25 years, the district has used two of the UGSI Chemical Feed model 32‐055 Feeders to mix dry hydrated lime with water to create a lime slurry solution that can then be added to the finished water treatment.
As engineers come under increasing pressure to reduce maintenance and operating costs, inefficient combination double-pass reverse osmosis and electrodeionization (RO/EDI) water treatment systems have begun to lose popularity as a means of providing ultra-pure water. Integrated membrane systems (IMS), on the other hand, combine multiple membrane-based water treatment processes into a single system. In this case study, find out how a heat and power plant in Northeast China lowered capital costs and energy use by adopting an IMS to replace its conventional water treatment system.
Small batches and multiple products in the same plant — these are the market demands to which more and more manufacturers need to adjust. The answer is based on the "Lego principle."

Water treatment filtration involves the removal of suspended particles from water by passing the water through a filtration medium. As the water passes through the filter, floc, minerals, microorganisms and other impurities get stuck in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Filtration is usually the final step in the solids removal process during water treatment which typically begins with coagulation and advances through flocculation and sedimentation.
Unfiltered or turbid water is difficult to disinfect because microorganisms growing on suspended particles are often harder to kill than when they are separated from the particles. Turbidity can also cause unwanted taste and odor issues in the potable water supply. Drinking water filtration is also used to remove microorganisms that are resistant to traditional methods of disinfection such as chlorination. By requiring a low turbidity in finished water, water treatment plants are ensuring that few or no microorganisms such as Giardia are present in finished drinking water.
There are three typical methods of clean water filtration used during the water treatment process. Conventional filtration follows coagulation, flocculation and sedimentation and precedes disinfection. Direct Filtration follows coagulation and flocculation when there is no sedimentation step. The final method called In-Line Filtration takes place without flocculation or sedimentation. A coagulant chemical is added to the water just before filtration and coagulation occurs in the filter.
There are many types of filter media being used in today’s water treatment industry.
