Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

Carbon dioxide cleaning was contemplated in the 1930s, and the "pellet" approach was developed in the 1970s by E.E. Rice, C.H. Franklin, and C.C. Wong. [4]: 276 The introduction of CO 2 snow cleaning, with its ability to remove sub-micron-scale particles, is credited to Stuart Hoenig of the University of Arizona , who first published on the ...
The soft, white, earthy mineral from Långbanshyttan, in Värmland, Sweden, known as aphrodite (Greek: sea foam), is closely related to sepiolite. [7] [23] In construction, sepiolite can be used in lime mortars as water reservoir. [24] Processes for bacterial transformation based on the Yoshida Effect can utilize sepiolite as an acicular ...
Long Retractable Sootblower utilizing steam as a cleaning medium. A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency. The world market leader is Clyde Bergemann Power Group. [citation needed] Types of ...
Blowers provide clean air to prevent contamination of electrical and optical surfaces from dirt, corrosive gases and overheating. Mains electricity is responsible for powering the blower’s motor. Different power ratings ensure that the required air flow is provided under different application conditions, duct pressures and hose lengths.
Deposit on a surface does not always develop steadily with time. The following fouling scenarios can be distinguished, depending on the nature of the system and the local thermohydraulic conditions at the surface: Induction period - Sometimes, a near-nil fouling rate is observed when the surface is new or very clean. This is often observed in ...
Diffusers are typically connected to a piping system which is supplied with pressurized air by a blower. This system is commonly referred to as a diffused aeration system or aeration grid . There are two main types of diffused aeration systems, retrievable and fixed grid, that are designed to serve different purposes.
The Ramsbottom test is used to measure carbon residues of an oil. In brief, the carbon residue of a fuel is the tendency to form carbon deposits under high temperature conditions in an inert atmosphere. This is an important value for the crude oil refinery, and usually one of the measurements in a crude oil assay.
