Grundfos Wastewater Treatment

Posted by on Saturday, 21 March, 2015

Wastewater treatment is the process of removing contaminants from water discharged from domestic, industrial or commercial premises as well as surface run-off. Wastewater treatment typically utilises mechanical, biological, and chemical processes to remove these contaminants. Grundfos can supply a whole range of components for a complete mechanical, biological, and chemical wastewater treatment plant.

The process of wastewater treatment varies from simple tanks, relying solely on sedimentation, to the refined treatment processes with advanced biological treatment that we know today. Treatment aims at reducing the pollution contained in the wastewater such as bacteria and viruses, oxygen consuming components, nutrients, pharmaceuticals, chemical substances and heavy metals from wastewater before it is discharged to the receiving waters.

Grundfos has decades of experience developing controller and monitoring systems for pumping solutions and manufactures its own pump motors for all fluid types and flow requirements. This ensures a perfect match with hydraulics, motors, electrics, and all other mechanical components that make up a comprehensive pumping solution, ensuring the best possible efficiency point.

Control and monitoring systems increase the potential for improving both efficiency and reliability. Grundfos supplies external variable speed drives (Grundfos CUE) that are pre-programmed for the Grundfos range of products, ensuring optimal operation.

The high-efficiency motors developed by Grundfos, with or without an integrated or external variable frequency drive, meet and in some cases exceed the requirements set by motor-efficiency legislation around the world. Considering that on average 85% of a normal pump system’s Life Cycle Cost (LCC) is energy costs, switching to Grundfos pumps with high-efficiency motor technology can mean a LCC reduction of up to 50% and a reduction in environmental impact.

Grundfos offers a broad range of equipment designed specifically for wastewater handling and treatment. The sustainability of a sewage treatment plant requires that the solution is durable, ensuring cost effective and trouble-free operation. Grundfos remains with you and your solution for the duration, offering commissioning agreements to ensure correct installation and service agreements offering cover for all eventualities, from routine maintenance to spare parts.

Grundfos DMX

Posted by on Tuesday, 17 March, 2015

General

The Grundfos DMX range has proven its worth in dosing applications worldwide. With their robust diaphragm-based design and their high-quality motors DMX pumps require minimum maintenance and are best choice for many dosing applications. The DMX range is highly versatile: it covers a wide flow range and offers a variety of dosing head sizes, materials and accessories.

Accurate dosing – all the time

The diaphragm design ensures that the dosing flow variation is below ± 1.5 % and the linearity deviation is kept below 4 % at all times. This allows very precise dosing of your chemicals – as much as necessary, as little as possible.

 

Smooth and low-pulsation dosing

The DMX series combines sophisticated drive technolo­gy and gear kinematics to ensure smooth and low-pulsation dosing without pressure peaks. This means less stress to all system components, such as tubes and valves, and leads to longer service intervals for the entire system.

Motors to match application needs

For applications with specific motor requirements, the versatile DMX range offers high-quality motors for 50 Hz, 60 Hz, 100 Hz (with Variable Frequency Drive VFD), as well as EX classified or ATEX-certified motors, if required.

Perfect material selection – for housing and liquid-wetted parts

The smaller DMX models have plastic housings offering chemical resistance and all the protec­tion necessary for many applications. The larger models have a robust cast-aluminium housing with epoxy coating to meet all application needs. Investment costs and running costs for spare parts are kept low over the years: A wide choice of materials for dosing head, valves and accessories allow selecting exactly the degree of chemical resistance required. All liquid-wetted parts need to be resistant to the chemicals used. The diaphragm is made of NBR and PTFE-coated.

Compact design – saves money and space

DMX pumps are available in 12 different dosing head sizes. Careful design work has kept them all very compact. This saves material costs and allows placing several pumps right next to each other in confined spaces. Double-head versions (DMX models 226 and 227) offer a very cost-efficient way to save space or to dose two different chemicals. The extra capacity offered by double-head versions can also be used to gain higher flow rates for a single chemical.

Accessories ensure perfect operation of the entire system

A wide range of accessories specially designed for the DMX series help optimise performance: AR control electronics (contact signal control with multiplier and divisor function, 4-20 mA control or stroke frequency control via display and key pad, low-level/empty signal), integrated relief valve, dosing controller, diaphragm leakage detection, servomotor for automatic stroke length adjustment, PTC motors with Variable Frequency Drive (VFD). We also offer system components such as pressure loading valves and pulsation dampers.

Applications

Disinfection, coagulation, flocculation, precipitation, etc. in:

  • Drinking water treatment
  • Waste water treatment
  • Pulp and paper industry
  • Textile industry
  • Cleaning water treatment
  • Food & Beverage industry, dairies
  • Cooling tower water treatment
  • Low-pressure boiler feed water treatment
