A process is provided for the treatment of water containing sulphide wherein the sulphide is oxidized in an aerobic reactor having a minimum sulphide sludge load. The minimum sulphide load is at least 10 mg of sulphide per mg of the nitrogen present in the sludge per hour, the sludge load ...
In order to prevent your drinking water from being contaminated with pollutants, it’s important to raise the pH range to healthy levels. Before breaking down how to raise pH in well water, let’s review some common signs of acidic water you should look out for. Symptoms of Low pH Well ...
Sludge granulation was closely related to the treatment performance of allicin-containing wastewater. Hence, the effluent COD concentration, the sludge morphology and physical characteristics were measured to reveal the effect of allicin stress on sludge granulation, as well as to further explain the mec...
water gas desulfurizing tower through a desulfurization pump; the semi-water gas desulfurizing tower is orderly connected to a semi-water gas converter, a converting/desulfurizing tower and a cleaning tower; the reaction tank is connected to the converting/desulfurizing tower; and the ...
TREATING METHOD FOR MAGNESIUM HYDROXIDE SUSPENDED WASTE WATER PURPOSE:To efficiently treat waste water without corroding an apparatus and attaching scale by contacting the waste water to combustion exhaust gas from which sulfur oxides are removed beforehand. CONSTITUTION:Combustion exhaust gas cont... AKAI...

The anaerobic and aerobic environments, as well as the DO gradient in the biofilm attached to the carriers, should allow various functional populations, including anammox bacteria, to flourish and cooperate with each other in the process. Inoculated with aerobic activated sludge, the HAOBR was ...
calcium sulfite is sprayed along with the water 6 from a tank 9 and the gas 8 contg. nitrogen monoxide at about 400 deg.C into an oxidation device 5. Consequently, the calcium sulfite in the ash is converted to calcium sulfate. The spent desulfurizing agent is made harmless at a ...
