12.5: Network Covalent Solids and Ionic Solids
Summary. The major types of solids are ionic, molecular, covalent, and metallic. Ionic solids consist of positively and negatively charged ions held together by electrostatic forces; the strength of the bonding is reflected in the lattice energy. Ionic solids tend to have high melting points and are rather hard.

Why are solids are floating on my secondary clarifier?
First floating sludge is most often caused by: Denitrification – small nitrogen gas bubbles float the sludge in the clarifier creating floating sludge chunks with small bubbles entrapped. Fats, Oils & Grease – simply put, FOG floats on water. When entrapped in floc, excessive grease or oil can cause floating biomass.

Pressure Effects On the Solubility of Gases
This statement is formalized in Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution. This can be expressed in the equation: C = k ×Pgas (1) (1) C = k × P g a s. where C C is the the solubility of a gas in solvent, k k is the proportionality ...
