An aerated lagoon (or aerated pond) is a simple wastewater treatment system consisting of a pond with artificial aeration to promote the biological oxidation of wastewaters. [1] [2] [3] [4]
Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
Rational emotive behavior therapy (REBT), previously called rational therapy and rational emotive therapy, is an active-directive, philosophically and empirically based psychotherapy, the aim of which is to resolve emotional and behavioral problems and disturbances and to help people to lead happier and more fulfilling lives.
Water aeration is often required in water bodies that suffer from hypoxic or anoxic conditions, often caused by upstream human activities such as sewage discharges, agricultural run-off, or over-baiting a fishing lake.
Often in non-Newtonian or pseudoplastic fluids, such as a digester with high solids concentration, it does make sense to use coarse bubble diffusers rather than fine bubble diffusers, due to the larger bubbles' ability to shear through more viscous wastewater.
Aeration of liquids (usually water) is achieved by: passing air through the liquid by means of the Venturi tube, aeration turbines or compressed air which can be combined with diffuser(s) air stone(s), as well as fine bubble diffusers, coarse bubble diffusers or linear aeration tubing.
Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1]
Logic-based therapy (LBT) is a modality of philosophical counseling developed by philosopher Elliot D. Cohen beginning in the mid-1980s. It is a philosophical variant of rational emotive behavior therapy (REBT), which was developed by psychologist Albert Ellis.
