W astewater systems and solutions provider Jacopa is entering the UK and Ire- land tertiary treatment market with a range of high-performance, low-op- erating cost, cloth media tertiary fil- ters for wastewater treatment. The FFP • xed plate cloth media • lters are manufactured by American company Flui- dyne, an innovator in • ltration technologies that supplies wastewater process equipment and technology across the world. The FFP • lters are used for phosphorus removal in wastewater treatment works, and have a wide range of further applications. As volumes of wastewater generated in the UK and Ireland continue to grow so does the Y orkshire Water is planning for a new-construction Aero- Fac system to replace the existing Withernsea Wastewater Treatment Works. Gurney Environmental says its Aero-Fac technology means "treatment works can normally be built for signi• cantly less than typical activated sludge works (less Capex), can operate at up to 85 per cent less than A/S (less Opex), and thereby result in far greater long-term sustainability (far less Totex)". Withernsea WwTW, which serves nearly 15,000 people, is located in the East Riding of York- shire. When it was last upgraded in 1991, it was 168 metres away from the cli• edge, but due to P ump manufacturer Sulzer has launched a range of sewage grinders called the Muffin Monster and the Channel Monster. Sulzer says its submersible sew- age pumps type ABS XFP with a Premium Eš ciency motor and the Contrablock Plus impellers o• er some of the market's highest hydraulic eš ciencies and feature superior rag handling capacity, but because of the growing rag content in modern wastewater, the com- pany is now o• ering sewage grind- ers to deal with the extra challenges presented by ragging. market for wastewater treatment technologies. In industry, new applications for reused water are rapidly emerging, and more eš - cient water recycling and process technologies can lead to a reduced water footprint across the water utility and industrial sectors. The deployment of tertiary treatment processes to polish eœ uents, reducing concentra- tions of suspended solids, is well established, and require- ments to achieve higher stand- ards is leading to increased interest in priority substance removal including phosphorus, putting more reliance upon ter- tiary treatment to maintain compliance with ever tighten- ing consent standards. signi• cant levels of coastal ero- sion, the WwTW is now only around 40 metres from the cli• and needs to be relocated. In addition to a new sewage works, a new sewer will need to be laid to transfer Ÿ ows from Withernsea to the new site, and a new sea outfall pipe will also be built next to the existing one. Yorkshire Water said the Aero- Fac system "means that construc- tion times will be reduced, traš c movements can be minimised and once • nished the site will be virtually noise-free. In addition, visual impacts and the risk of odour will be greatly reduced", adding: "The system is more sus- tainable and has a much lower carbon footprint." The Muffin Monsters, available in three sizes, are powerful and compact grinders that fit into both smaller and larger pump stations as well as within the sludge processing systems of treat- ment plants. The Muffin Monster dual-shafted grinder uses low speed and high-torque to shred through a range of difficult sewage debris. The Channel Monster, mean- while, is a powerful, high-flow sewer grinder mainly intended for large pumping stations and headworks. This Monster uses rotating drums to capture solids and direct them into Sulzer's dual-shafted grinders. WHAT IT IS: The S160Eco was developed by Selwood to complement its S range of solids- handling pumps. Driven by an Isuzu diesel engine, the six-inch S160Eco is o• ered as an upgrade over Selwood's current S150 model, o• ering a 28.5 per cent increase in pressure, resulting in an extra 5m head. It is suitable for a full range of sewage, sewer bypass, overpumping, water and wastewater applications. WHAT'S GOOD ABOUT IT: It is designed to handle large solids including raw sewage and ‚ brous solids without blocking, and Selwood says it is the quietest pump on the market as tested against EU directive 2000/14/EC. The emissions compliance ensures the S160Eco can be used in inner cities where the most stringent regulations apply. WHAT THEY SAY: Selwood CEO Chris Garrett says: "Customers in the water and wastewater sector are increasingly seeking to reduce emissions, and ever more stringent regulations make it paramount that Selwood remains at the forefront of environmentally- friendly technology. It is also important to us that customers achieve this without sacri‚ cing performance. Our engineers have developed the S160 Eco speci‚ cally in response to these demands and it is a credit to them that they have produced a unit that meets emissions demands and o• ers improved performance when compared to our benchmark S150 model." Xylem Flygt 4220 mixer Xylem has launched a compact submersible wastewater mixer featuring easily adaptable output capabilities and delivering energy savings of approximately 50 per cent. The Flygt 4220 mixer enhances the resilience and sustainability of WwTPs, enabling operators to easily manage changing mixing conditions by adjusting the mixer output. As the Flygt 4220 can be controlled to deliver only the output required, a plant's energy consumption can be signi‚ cantly reduced. The Flygt 4220 mixer is based on Xylem's Flygt Dirigo platform of integrated power electronics, including an IE4 super premium e— ciency motor, and is available in 1.5, 2, 3 and 4 horsepower versions. Sykes Pumps GP80 Eco Pump hire specialist Sykes Pumps has added the GP80 eco to its eco range of diesel pumps, providing a solution for construction and civil engineer- ing sites as well as utilities, local authorities, industrial, marine, quarries and leisure. Featuring a silenced engine o• ering tier 4 compliance for discreet deployment in residential and noise-sensitive areas, the 3" diesel pump has an integral 35-litre fuel tank that enables continuous operation for 24 hours. Capable of heads of up to 24m and a maximum flow rate of 36 litres/second, the new pump provides a solids handling capability of 40mm. KSB Sewatec In response to the worldwide increase in extra-large wastewa- ter projects, Germany's KSB SE & Co KGaA has signi‚ cantly extended its range of large dry-installed wastewater pumps. The pump manufacturer has developed an extra 15 sizes to add to its Sewatec pump series. The maximum flow rate of the largest version will be up to 33,000 m³/h with a drive rating exceeding one megawatt. The Sewatec type series comprises horizontally or vertically installed, single-stage volute casing pumps in back pull-out design. Depending on the fluid handled, they can be ‚ tted with a variety of impeller types.
