Water / Wastewater Treatment


from Franklin Miller (USA) provides effective, automatic screening and grinding of wastewater solids in straight through channels and wet wells. This powerful unit reduces plastics, wood, rags and other solids to fine bits, enhancing plant operation and improving the reliability of pumps and other downstream equipment.


Automatic Sreening and Grinding of Wastewater Solids The Dimminutor®


The Dimminutor employs a smooth, continuously rotating design with high torque. As its three bidirectional rotary cutters intermesh at close clearance with stationary cutters, solids are finely reduced to a size small enough to pass through a sizing screen. With no gaps or openings between the screen and cutters, output is controlled and complete reduction assured.


The Dimminutor has an intrinsically open design to handle high flow rates with low head-loss. This unit is extremely easy to maintain and features individually replaceable cutters, oil lubrication and a simple rotary design requiring no auxiliary diverter screens. A unique, cantilevered design eliminates seals or bearings near the gritty channel floor. Every component of the unit is constructed for precision and long life.

Water Treatment Plant Achieves Three Million Cubic Meters of Treated Water


A water treatment plant operated by GE recently achieved a major milestone for long-term efficiency and reliability: three million cubic meters of treated water, or approximately 800 million gallons, produced for EDF Energy’s Hinkley Point B Nuclear Power Station on England’s south-western coast.


The water treatment plant was built by GE in 2003 and replaced an aging water treatment plant at the site. It is a build-own-operate (BOO) project; only GE operates BOO systems within the United Kingdom’s nuclear industry.


“The BOO arrangement transfers the risk and responsibility for producing treated water from EDF Energy to GE. This has allowed EDF Energy to focus on our core competency, which is producing electricity,” said Mike Davies, operations services group head for EDF Energy.


The water treatment plant at the Hinkley nuclear station, which is located near Bridgewater in Somerset, produces 55 cubic meters per hour of treated demineralised water to nuclear industry standards. The plant supplies ultra-pure water to the main boiler feed systems, the fuel cooling ponds and a variety of auxiliary circuits.


“A reliable supply of treated water is critical for the successful operation of the Hinkley nuclear station, which is a key provider of clean energy for England,” said Kerry Murphy, general manager—water outsourcing and mobile water for GE Power & Water. “By using advanced technology from GE’s water and process technologies business, the water treatment BOO plant has increased its efficiency and reliability, which in turn reduces energy consumption and environmental footprint.”

$10 Billion Cross Flow Membrane Market


The world market for cross flow membranes and equipment will grow 31 percent from 2010 to over $10 billion in annual revenues in 2015. East Asia will have the largest growth rate and will be the largest regional buyer. These are the latest forecasts in the McIlvaine continually updated RO, UF, MF World Markets report.

Ultrafiltration Modules Donated to Treat Drinking Water in Pakistan


Catastrophic flooding in Pakistan has pushed the population’s need for clean drinking water even higher up the agenda. The German ultrafiltration specialists inge watertechnologies AG were already an established supplier of ultrafiltration modules in the Pakistan market when the flooding hit, and the company has now been using its existing contacts to ensure that the modules it is donating to five water treatment plants arrive safely.


Clean Drinking Water for All (CDWA) is a project that was launched by the Pakistan


government with funding from various development aid organisations before the floods struck. Its goal is to improve the country’s drinking water situation by installing modern drinking water plants in all 35 provinces. Work has already begun on some of the 6,000 plants that are planned, and the government hopes to eventually install a total of between 20,000 and 30,000 plants spread across all the provinces. In Pakistan’s largest province, Punjab, 1,600 plants are scheduled for construction, each of which will employ modern methods of ultrafiltration, a membrane process used to treat drinking water, process water, wastewater and sea water. This technique uses extremely small-pore filters to remove


suspended solids, viruses, and bacteria from water using purely physical means – without requiring the addition of chemicals. The German company, which has been successfully doing business in Pakistan through a subsidiary for decades, is one of the partners


involved in the CDWA initiative. It placed its initial order for 800 ultrafiltration modules to equip its new treatment plants with the German company inge watertechnologies AG.


The modules the company produces operate at a capacity of either 2,000 or 4,000 litres of water per hour, enabling a treatment plant


to convert a total of approximately 50,000 m³ of water into clean drinking water each day. KSB is now donating the construction of a further five plants, which inge watertechnologies AG will be equipping – at no charge – with ultrafiltration modules. This will enable a further 20,000 liters of water to be converted into clean drinking water each day.


Bruno Steis, CEO of inge watertechnologies AG, comments: “With the country going through such a tremendously difficult time, we hope that our technology can make a small contribution towards helping people in Pakistan get access to clean drinking water.”

The East Asia growth is spurred by expansion of the semiconductor industry, the need to desalinate seawater, growing power plant ultrapure water requirements, and the incorporation of cross flow filtration in the upscale commercial and residential buildings. Another growth segment is to purify municipal and industrial wastewater for reuse.


The growth in the Middle East will be primarily for sea water


desalination. The European and NAFTA countries will be the leading purchasers of cross flow membranes for pharmaceutical and biotechnology applications.


The resurgent nuclear power industry offers attractive opportunities for suppliers of cross flow membranes and equipment. Gas shale and other unconventional oil and gas extraction are also expanding markets.

Manganese Elimination from Drinking Water


Severn Trent Services - Apliclor, a leading supplier of drinking and wastewater treatment solutions in Spain, has designed and supplied new filtration and disinfection equipment for the Cadalso de los Vidrios drinking water treatment station, owned by the public company Canal de Isabel II. The upgraded facility, which came into operation in August, serves the needs of some 3,000 inhabitants in the Community of Madrid.


Severn Trent Services – Apliclor’s treatment approach was


Seawater Sulphate Reduction Package used Offshore in Brazil


VWS Westgarth (UK), a Veolia Water Solutions & Technologies company, has been awarded a multi-million dollar contract by SBM Atlantia for their FPSO to be installed in the Baleia Azul field, Campos Basin, offshore Espirito Santo state, Brazil.


The award is for the design, supply and delivery of a single lift module seawater sulphate reduction package (SRP) system with a capacity of 20,060 m3


/day (126,000 BWPD).


The SRP is designed to remove sulphates and other divalent ions from injection water to enhance oil recovery using Dow Filmtec membranes. The removal of these ions reduces the tendency of barium sulphate and strontium sulphate scale to form in the reservoir.

two-fold and included the installation of pressure filters to effectively eliminate manganese and other solid particles from the community’s water. In addition to the pressure filters, Severn Trent Services- Apliclor also installed sodium hypochlorite dosing systems to disinfect the drinking water. The total treatment scheme represents an investment of almost EUR 160,000 (USD 220,450).


According to Rick Bacon, general manager of Severn Trent


Services – Apliclor, “Manganese is an element commonly found in ground water, often in combination with iron. While not dangerous to public health, the presence of manganese can damage clothing during washing, which is why Canal de Isabel II has decided to invest in new filters to eliminate the contaminant.”
