The potable water plant currently controls pH by dosing lime slurry using a PC pump, which runs for approximately 12-16 hours a day at a rate of 900 litre/hour. Reliable, consistent flow Watson-Marlow has supplied a Bredel APEX35 hose pump to the New Braunfels CRWA plant so that engineers can see the benefits of using a hose pump to handle the ...
Verderflex® hose pumps are predominately used in the dosing process to treat wastewater. The source of wastewater can be divided into three categories, manufacturing wastewater, drainage from Ultrapure water based manufacturing, and washing exhaust. ...

The water is channelled from the tank and filtered to remove solid matter, however the water is left with higher levels of acidity. The water was dosed with lime chemical and returned to the tank. The fish farm approached Verder for a dosingsolution. Verder recommended a Dura packaged dosing system. The system was recommended as it provided a ...
Subsequently, they are ideally suited for handling ‘difficult’ fluids – abrasive, corrosive, viscous, shear-sensitive, crystallising or even fluids presenting a combination of these properties. Precise dosing capability Offering the best performance available on the market for pressures up to 8 bar, along with reliable and stable flow up 1200 l/h (with 20mm ...
Lime slurry is a dense product to transfer with a high solid content of up to 35%. ...
The Moyno 2000 CC Pump is ideal for: Positive displacement sludge transfer Scum and grease pumping Dewatering equipment feeding Lime slurry transfer and dosing Polymer transfer and dosing Chemical metering and transfer Sampling influent and effluent Moyno, Inc., part of the Fluid Management Group of Robbins & Myers, Inc., is a ...
This makes a Verderflex peristaltic pump a hygienic choice for pumping chemical and pharmaceutical products, liquids with high solid content and tough and abrasive media. The dosing action of the pump also provides an even and accurate dose, allowing the user control over the measurements being pumped. Ideal for dosing lime for ...
This has been successful in treating upland Pennine waters and, as a result, water quality throughout the area has improved.A critical aspect of the water treatment process at Blackmoorfoot is the addition of lime slurry, to control the pH of the water. Water enters the works with a pH of around 6 and is then is then dosed with ferric sulphate and brought to a pH ...
A critical aspect of the water treatment process at Blackmoorfoot is the addition of lime slurry, to control the pH of the water. Water enters the works with a pH of around 6 and is then is then dosed with ferric sulphate and brought to a pH of 3.5. Lime is then added to aid flocculation at the first stage of filtration – bringing the water to ...
The viscous lime slurry used to maintain a neutral pH during the water treatment process was causing frequent blockages in the diaphragm pumps used by Buckton Castle WTW. ...
Yorkshire Water is one of the principal water and waste water treatment companies in the UK and had a problem with a lime dosing application at the Ruswarp Water Treatment Works near Whitby, Northern England. Lime dosing is a classical Verderflex® application with many installations in the water industry and the following ...
An integral part of the water treatment process at Bamford is the addition of lime slurry, to control the pH of the water. Water entering the works is dosed with ferric sulphate and a polyelectrolyte and brought to a pH of between 4.7 and 5.1. If the water is lower than this pH, it is dosed with lime in order to bring it up to ...
The viscous lime slurry used to maintain a neutral pH during the water treatment process was causing frequent blockages in the diaphragm pumps used by Buckton Castle WTW. ...
After 14 years in continuous operation, the peristaltic pumps used for lime dosing at Clay Lane Water Treatment Works (WTW) have been upgraded as part of a project to optimise performance at the site. ...
