Algae causes many problems in wastewater systems. They clog screens and reduce oxygen. They raise operating costs. Often, conventional fixes use heavy chemicals. Those chemicals harm aquatic life and add expense. A newer option uses sound to fight algae. This method offers chemical-free algae removal and saves money. It also fits industrial algae treatment needs. Below is a clear guide for ...
Water Supplier’s Investment in Sound Wave Resonance Replaces Decades of Applying Copper Sulfate in an Open Drinking Water Reservoir The Syracuse Water Department (SWD) is responsible for managing an unfiltered drinking water supply for the City of Syracuse. The source water is Skaneateles Lake, located in the Finger Lakes region of New York State, approximately 20 miles southwest of the ...
Aquatic plants fulfill various ecological roles; they are a natural part of every lake and their surroundings, and they interact with a wide range of organisms. When restoring a lake’s ecosystem, it is crucial to assess its aquatic vegetation ...
Abstract :Comparison is made between results of tests performed using the conventional algal growth inhibition test according to ISO 8692, in 250 ml Erlenmeyer flasks and based on laboratory algal cultures, with electronic counting of the algal cells (N), and those obtained with the Algaltoxkit-F™ tests using algal beads, long cells and Optical Density (OD) measurements. The exercise ...
Five solar-powered algae control systems where installed in the Lower Nihotupu Dam in Auckland, New Zealand to reduce the levels of blue-green algae. The project started in December 2016 and so far, the project appeared to be of great success with the blue-green algae count over summer 90 per cent less than the previous year. ...
Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...
The present study investigates the biological and chemical analysis of water at all periods of the Nile River. The results show that the algae count ranged from 221 to 2,069 organism/ml during flood and drought periods respectively. ...
The applied alum coagulant dose was slightly reduced while residual Al was reduced by 27% and the algal count by 50% in the final treated waters. Applying ferric chloride and ferric sulfate as coagulants to waters treated with the combined pre-oxidation procedure effectively reduced algal count by 60% and better the total organic carbon reduction and residual ...
Four solar-powered algae control buoys were installed in the Canoe Brook Reservoir #1 in Short Hills, NJ to assess the impact of the system for controlling algae and cyanobacteria in the raw water reservoir. ...
