Removal of suspended solids by coagulation and foam separation using surface-active protein

Development of a New Material for Mine Fire Control

“…This is because the fly ash will fractionate out a mass of metal ions, such as Ca 2+ , Mg 2+ , when it disperses in the water. Furthermore, the water used in the experiment contains a lot of Ca 2+ , Mg 2+ , which can react with some surfactants of foaming agent to decrease the amount of foaming agent used in foaming (Sone et al, 2009;Suzuki and Maruyama, 2002). Previously, we tested the effects of calcium chloride (CaCl 2 ) with different concentrations on the foam volume; the results are shown in Table 1.…”

Biocoagulation of dairy wastewater by Lactobacillus casei TISTR 1500 for protein recovery using micro-aerobic sequencing batch reactor (micro-aerobic SBR)

“…High level of organic matter may pose a serious problem to the conventional wastewater treatment plant (activated sludge) in decreasing BOD concentration to less than 20 mg L À1 . Pre-treatments were introduced by membrane [1], chemical [2][3][4] and simultaneously physico-chemical [5,6] methods to reduce the organic load. Nevertheless, these processes had an inherent drawback due to high operating costs from either the use of external acid sources or flocculating agents.…”

“…The dairy process wastewater was coagulated by acid fermentation with the micro-aerobic SBR operation using five different SRTs(3,6,9,12, and 15 days). (A) Organic acids: acetic acid (*), butyric acid (5), lactic acid (&), and succinic acid (^), (B) sugars: lactose (*), and sucrose (5), and (C) average values of organic acids.…”

Formation and speciation of disinfection byproducts during chlor(am)ination of aquarium seawater

“…Pre-ozonation has been commonly applied in the foam fractionation process of aquarium seawater treatment systems to enhance the removal of suspended solids and DOM (Suzuki and Maruyama, 2002). The effect of pre-ozonation on the formation of DBPs depends on water quality parameters (Hua and Reckhow, 2013).…”
