Alum and Ferric Chloride: Pros, Cons, and Substitutes for Treating Water
Many water plants can’t afford a 40% price increase, so they’re looking for alternative products. What are some substitutes for alum and ferric chloride? Substitutes include other aluminum and iron salts, like sodium aluminate and ferric

How Many Microns Should Your Water Filter Be? – Fresh Water Systems
A micron is a unit of measurement describing the pore size of a micron water filter. Sediment filters remove different contaminants depending on their micron rating. John Woodard, our Master Water Specialist, explains the difference between a .1
In the simulated drinking water purification processes, synthetic organic poly- mers were used as coagulant aids, reacted with a disinfectant (chlorine) and formed a large number of vola- tile organic compounds (VOCs). Chloroform and benzene

Coagulation of low temperature and low turbidity water: Adjusting basicity of polyaluminum chloride (PAC) and using chitosan as coagulant aid
Subsequently, the coagulation performance of the water treated with PAC alone was compared with that of the water treated with PAC together with chitosan as a coagulant aid. Fig. 6b reveals that the combined usage of PAC and chitosan generally
The Australian Drinking Water Guidelines (the Guidelines) provide a basis for determining the quality of water to be supplied to consumers in all parts of Australia. They are intended to provide a framework for the good management of drinking wa
- Who is responsible for water supply & wastewater management in Germany?
- In Germany , water supply and wastewater management are the responsibilities of municipalities or other public corporations (Bauby 2011). The Drinking Water Ordinance of the Federal Ministry of Health governs the quality of drinking water, and it is enforced at Länder level (BMU 2014).
- What is a “minimization rule” in German drinking water?
- Thus, the German government attempts to “keep [a] hazardous substance which can influence drinking water quality , as low as achievable according to the generally acknowledged technical standard of treatment within [reasonable] expenditure [limits]” according to the “minimization rule” of the German Drinking Water Ordinance (Markard 2014).
- What are the long-term goals of German water protection policy?
- The long-term goals of German water protection policy are: to secure for the long term all other water uses that serve the public interest. Such uses include leisure and recreation, shipping and energy production. To achieve these goals, water protection policy is based on: cooperation among all water users and stakeholders in water protection.
- What are the shortcomings of the German approach to drinking water?
- The shortcoming of the German approach is that the sum of values of chemical compounds from mixtures of contaminants in drinking water has not been used. In other words, something comparable to the Dutch concern for “concentration action ” of mixtures of compounds should be adopted in Germany .
