The Los Filtros Guaynabo Water Treatment Plant in Puerto Rico installed a Real UV254 M3000 analyzer to monitor raw water organics fluctuations and feed a coagulation optimization system supplied by local partners Montanas Electric, Inc. and Nator Corporation. With reliable real-time organics information the plant was able to automate their ...
Water Quality Monitoring Solutions for Industrial Wastewater – Coagulation Control s::can sensors combined with process control software can provide feed forward coagulant dose control to fully optimize operations. ...

Coagulant dosing control in drinking and wastewater treatment plants (WWTPs) is often limited to flow proportional concepts. The advanced multi-parameter-based dosing control systems have significantly reduced coagulant consumption and improved outlet qualities. Due to the long retention time in separation stages, these models are mostly based on ...
To counter this there is a common practice of chlorinating, acidifying and coagulating the feed water. This is done principally with the commodity chemicals, sodium hypochlorite, sulphuric acid and iron chloride coagulant. ...
In order to protect public health during swimming, Cryptosporidium-sized microsphere removals by high-rate sand filtration with six coagulants were evaluated with a 5.5 m3 pilot-scale swimming pool. A sand filter without coagulation removed 20–63% of Cryptosporidium-sized microspheres. Cryptosporidium-sized microsphere removals exceeded 98% by sand filtration ...
A variety of surface waters used for drinking water sources were collected from different parts of Japan to investigate a correlation between the concentration of hydrophilic biopolymer (e.g. proteins and polysaccharides) in the feed water and membrane fouling in microfiltration. Hollow-fiber membranes made from polyvinylidene fluoride with a nominal pore size of 0.1 μm ...
An automatic coagulant dosage control technology for water purification plants was developed to deal with rapid changes of feed water quality. Control logic was developed to decide coagulant dosage based on aluminum concentration in the mixing tanks. A coagulant-sedimentation process apparatus was installed in December 2010 in ...
This paper describes the use of both the streaming current detector (SCD) and coagulation computer models to provide real-time data for required coagulant feed rates. ...
Morgan water treatment plant (WTP) operates overnight to take advantage of off-peak electricity, however the stop/start practices add an additional complication to accurate coagulant dosing. Online monitoring and feed forward prediction is ideal in these situations as it can provide information while there is still a chance to make adjustments, unlike the ...
As part of Lee County’s treatment plant reservoir and plant improvements for the Olga Water Treatment Plant (WTP), Parsons has been contracted to replace the current alum coagulation feed system with a ferric sulfate coagulation feed system. In order to determine chemical feed rates and their impact on water ...
