Activated bentonite was characterized and used as an adsorbent for the removal of Fe ions from acid mine drainage (AMD) sourced from a gold mine site. Adsorption experiments were carried out under varying operating conditions in a glass continuous stirred batch reactor by agitation of bentonite clay with a fixed volume of AMD.

The role of ASCH particles on the interparticle association of the bentonite fluids is different from that of ICH and sensitive to pH. As pH of ASCHadded bentonite suspensions increased, the viscosity, yield stress, storage modulus, and flow stress decreased. In contrast, at low pH, the clay suspensions containing ASCH additives were coagulated and their rheological properties become close to

· pH is an important part of aquaculture. Setting it to a perfect level can be a bit confusing since there are three living organisms to care for: your plants, your fish, and the bacteria inside the water and each of them has a different pH need. A neutral pH from to is good for the aquaponic garden. Because of the fish waste, the pH will become acidic and you will need to use aquaponic

The soil pH falls rapidly following application as the hydroxide ion from lime application reacts with carbon dioxide. Also, in acidic soil, the pH falls as lime reacts with soil acidity. This increases soil pH, but it causes the initial high pH resulting from hydroxyl ion to fall quickly to a level too low to kill unwanted organisms. Farmers

· The white shrimp Litopenaeus vannamei has widely replaced Penaeus monodon as the cultured species. One of the reasons for this change is the fact that L. vannamei can be cultured in higher densities and with a lower exchange of water, which increases the biosecurity.
