Analysis of Technologies for Small Water Systems
The problems encountered when small systems must meet the provisions of the National Primary Drinking Water Regulations are discussed. Among the potential water quality problems that could...
Problems in Design of Small Reverse Osmosis Water Purification Systems
Small reverse osmosis water purification systems may be defined as those systems which produce from 100 to 20,000 gallons of water per day. This paper identifies some of the common problem...
A Survey of Anaerobic Digester Operations
In 1981, the ASCE Task Committee on Anaerobic Digestion conducted a survey of wastewater treatment plants throughout the country regarding the use of anaerobic digestion. The two-part...
Factors Influencing Oxygen Depletion in Green Bay
Dissolved oxygen depletion in the lower Fox River (Wisconsin) and Green Bay (Lake Michigan) have historically been tied to discharges of organic matter from municipal waste treatment plants...
Geothermal Salt Recovery From Evaporating Ponds
The water from geothermal reservoir 'Los Azufres' in Michoacan, Mexico, is characterized by its high content of chloride, silica, borum and arsenic. Due to the...
Impact of Metallic Solders on Water Quality
A description is given of first-draw water testing at residences in a Long Island, N. Y. , water district. Results for heavy metals, particularly lead, leaching from the solder and plumbing...
