Sludge

Life With Dick is the new album by Grace Sings Sludge (The Sandwitches, The Fresh and Onlys). It's the continuation of a world Grace Cooper began illustrating as one of the lead songwriters of the San Francisco band The Sandwitches, and on her previous three collections of solo home recordings (released as limited run cassette tapes). As with the other solo albums, Cooper does the artwork for the album. Her delicate yet disturbing pen and watercolor creations are the perfect accompaniment to her songs, as though they've emerged from the same troubled dreams.

Activated Sludge Separation Problems: Theory, Control Measures, Practical Experiences, Second Edition, describes the most common activated sludge separation problems and explains the main reasons for the growth of the different filamentous microorganisms in activated sludge. The book summarizes the identification techniques for important groups of activated sludge microorganisms both based on conventional microscopic analysis and using the biological molecular tools available today (FISH and PCR).

In this collection, the authors report on the pretreatment methods for waste activated sludge based on pulsed electric field and corona discharge techniques

Aerobic Granular Sludge has recently received growing attention by researchers and technology developers, worldwide. Laboratory studies and preliminary field test led to the conclusion that granular activated sludge can be readily established and profitably used in activated sludge plants, provided "correct" process conditions are chosen.

It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures.
