Water Treatment: Thinking Small

As populations grow, as urban, suburban and ex-urban areas expand, demand for water increases and safety standards rise. An effective and creative way to deal with problems of growth and resource management might just be to think small. A case in point is the Olivenhain Municipal Water District's (OMWD) treatment facility in San Diego County, California.

Aeration for Ponds and Cisterns

Using oxygen for the natural cleansing of water is becoming a viable alternative for pond and cistern owners in reducing the use of chemicals to fight the bacteria and algae that can become a nuisance. An aerobic bacterium needs oxygen in order to maintain the balance of nature. This article will take a look at some methods for increasing oxygen content, Henry's Law and applications that benefit from increased levels of O2.

Fine Bubble Aeration/Mixing System Cuts Lagoon Treatment Energy Costs

The Biomixer Aeration and Mixing system is providing optimum dissolved oxygen transfer and mixing at this lagoon, in spite of the number of units being reduced from the original design of five units down to three. This is being obtained with the dissolved oxygen levels throughout the basin averaging 9.1 mg/l. Even at the influent end of the basin where the loading rate is the highest, the dissolved oxygen readings were above 8.5 mg/l.

Back to the Basics, Part 3

In this last section of a three-part series, the use of ozone, ionization, distillation and aeration is discussed in a simple fashion to help the beginner rationalize the importance for a full understanding of these technologies and the need, again, for a professional water treatment specialist.

This is the final article in a three-part series discussing water chemistry and technology basics.

Practical Engineering Combined with Sound Operations Optimizes Phosphorus Removal

Built in the early 1970s, The Oakland, Maine, Wastewater Treatment Facility (WWTF) treats and discharges approximately 300,000 gallons per day (gpd) of wastewater to the Messalonskee Stream. The facility was designed as a conventional activated sludge secondary treatment system to be used principally for BOD and TSS removals. The secondary effluent enters the Messalonskee Stream upstream of several impoundments. This practice has resulted in a steady decline in the water quality of the stream as evidenced by increased algae blooms and other signs of euthophication in impoundments located downstream of the discharge.

Biofilm Elements Treat Colorado Town

Kaldnes North America, an Anglian Water Company, was chosen to supply the city of Broomfield, Colo., with the Moving Bed Biofilm Reactor (MBBR) process to treat its municipal wastewater.

 

Under the terms of the contract, Kaldnes will retrofit Broomfield's existing aerobic basins with Kaldnes media, an aeration grid system and sieve assemblies. In addition, there will be new construction for phosphorus and nitrate removal.
