A Parliamentary initiative (10.503) launched by National Councillor Adèle Thorens Goumaz (Greens) calls for rainwater to be used more extensively for purposes that do not require drinking water quality. The initiator is hoping to reduce the consumption of drinking water as a result. In addition, the initiative is seeking to increase the amount of rainwater that percolates into the soil. Eawag research projects show that the collection and storage of rainwater is costly, as is any purification required. On the other hand, percolation of rainwater into the soil can help alleviate incidents of flooding.
Removal of Fallen Leaves Can Improve Urban Water Quality
The timely removal of leaf litter can reduce harmful phosphorus concentrations in stormwater by over 80 percent in Madison, Wisconsin, according to a recent U.S. Geological Survey study. Autumn leaf litter contributes a significant amount of phosphorus to urban stormwater, which then runs off into waterways and lakes. Excessive amounts of nutrients like phosphorus and nitrogen can cause eutrophication, or the depletion of oxygen in water, resulting in death of aquatic animals like fish. The USGS-led study found...
Neuthox in agriculture - improving water quality and increasing revenue - Case Study
Adding NEUTHOX to the water supply will improve weight gains, and lower the mortality rate. NEUTHOX is proven to: Reduce bacteria levels in the local water supply Remove biofilm in the water system Reduce animal self-contamination of drinking water Be an eco-friendly, non-toxic and economical solution Neuthox - increasing growth ratesImproving the quality of animal drinking water is one of the key elements when working to increase animal health, and maximize revenue. By reducing the bacteria level in...
Neuthox improves the water quality by removing unwanted bacteria - Case Study
NEUTHOX removes biofilm in cooling tower and leaves the water system completely free of unwanted bacteria Using an electrolysis process of saltwater the ECA generator produces the liquid NEUTHOX, which contains hypochlorous acid, and is highly efficient in eliminating bacteria.A biofilm consists of living and dead organic and inorganic material collected on a surface, which in water systems typically occurs as a patch on a pipe surface. Biofilms contribute to increased bacterial levels, reduction of dissolved...
An assessment of static and dynamic models to predict water treatment works performance
The relative accuracy of static and dynamic water treatment works (WTWs) models was examined. Case study data from an operational works were used to calibrate and verify these models. It was found that dynamic clarification, filtration and disinfection models were more accurate than static models at predicting the final water quality of an operational site but that the root mean square errors of the models were within 5% of each other for key performance criteria. A range of abstraction rates at which the WTWs...
Management of unregulated agricultural nonpoint sources through water quality trading market
Water quality trading (WQT) could be an innovative policy to incentivize farmers to implement best management practices (BMPs) for their activities. This study focused on assessment of involving unregulated agricultural nonpoint sources (NPS) into the WQT market in Gharesoo watershed in the west of Iran. It also proposes a methodology to determine location-based trading ratios as well as environmental penalty cost to achieve a more well-designed market structure. Trading activities in different scenarios were...
