Environmental Technology Verification Report for Ammonia Recovery Process
Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Service Center. This report describes the nature and scope of an environmental...

Ozonization of Anaerobic Sludge Dewatering Centrate for Ammonia Removal
Semi-batch ozonation experiments were carried out on settled anaerobic sludge dewatering centrate. The observed rate of ammonia decay at pH ranging between 7.5 and 8.5 was much slower...

Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...

Evolution (1980-1990) of Ammonia and Dissolved Oxygen in Guanabara Bay, RJ, Brazil
The UFRJ is located on an island of Guanabara Bay and the Institute of Biology has been developing systematic studies on the bay. A synthesis of these studies and their different methodologies...

Optimization Study of a Leachate Treatment System
A treatability study was conducted to evaluate the need for a metal precipitation and an ammonia stripping process in a leachate treatment system and to evaluate the biological nitrification...

Chloramines: A Better Way?
Chlorination of drinking water has been linked to the formation of carcinogenic trihalomethanes (THMs). By adding ammonia to the water, the chlorine becomes chloramines which don't...

Experimental Verification of a Unified Chlorine-Ammonia Reaction Model
A model of the reacting aqueous chlorine-ammonia system is proposed which describes equally well the rapid 'breakpoint' oxidation of ammonia or the slow decomposition...

Implications of Nitrogen Transport by the Okanagan River
The long-term mean of total nitrogen load estimated in the river channel above the inlet to Skaha Lake is 906 lb day** minus **1. The apportionment of ammonia and nitrate plus nitrite...

The Use of Activated Carbon as a Polishing Step for Treatment of Industrial Plating Wastewaters
An activated carbon adsorption process was utilized as a polishing step following the precipitation (hydroxide or sulfide) process. Zinc and cadmium were the metals studied. Since plating...

Weather Modification Potential ? Santa Clara Valley
Santa Clara County of California has been a water deficient area. The Santa Clara Valley Water District has an obligation to the community and to the other water users in the State to...
