The addition of synthetic flocculants to the bioreactor can increase the average particle size making microfiltration more efficient. When flocculants are not added, cakes form and accumulate causing low cell viability. Positively charged flocculants work better than negatively charged ones since the cells are generally negatively charged. [10]

Long-chain polymer flocculants, such as modified polyacrylamides, are manufactured and sold by flocculant producers. These can be supplied in dry or liquid form for use in the flocculation process. The most common liquid polyacrylamide is supplied as an emulsion with 10-40% actives and the rest is a non-aqueous carrier fluid, surfactants and ...

Jar test for coagulation. The dose of the coagulant to be used can be determined via the jar test. [1] [5] The jar test involves exposing same volume samples of the water to be treated to different doses of the coagulant and then simultaneously mixing the samples at a constant rapid mixing time.

Sensor operated plumbing fixtures have fewer moving parts, and therefore outlast traditional manual flush fixtures. Additionally, they reduce water consumption by way of intelligent flushing schedules (fuzzy logic) that determines the quantity of each flush based on how many people are standing in line to use the fixture. A wall-mounted shower ...
Dosage of defoamer. A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably.
There is currently much research on using biocompatible polyelectrolytes for implant coatings, controlled drug release, and other applications. Thus, recently, the biocompatible and biodegradable macroporous material composed of polyelectrolyte complex was described, where the material exhibited excellent proliferation of mammalian cells [ 7 ...
