Aeration and Mixing Bring Hussain Sagar Lake`s Ecosystem Back to Life

Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration ...

Importance of Air & Water Testing in Indoor Pools

Have you ever wondered why your eyes hurt or why you have a cough after swimming at an indoor pool? We all assume that it’s from too much chlorine in the pool but that is false! If the pool staff doesn’t regularly test and monitor both the air and water indoors, the environment becomes very toxic and unsafe to everyone in the building. Water is an essential ingredient for all life as ...

Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

AIRE-O2® Aerators tests number one in three critical areas

Problem In 1986, this southern USA fine paper mill developed problems on start-up from a Christmas shut-down, requiring quick action to add efficient aeration to its 38 MGD (143,830 m 3) flow. Poor winter treatment, channeling throught the system, and high solids had also been problems. Since the company was committed to preserving the environment, it searched for the best aerators to meet its ...

Ground Zero Air Quality Has A Long Way To Go! A Summary of Air Quality Testing in Surrounding Buildings

There are still a wide range of concerns about air quality in the vicinity of Ground Zero. Many commercial and residential spaces have yet to be re-occupied. In only a few cases has any sort of inspection or testing been done to determine if they are safe to occupy. The greatest concerns are asbestos and the very irritating concrete dust that spread throughout lower Manhattan during the collapse ...
