Celtic Technologies Ltd, the Cardiff, UK-based contaminated land and groundwater remediation specialists, is currently engaged on a contract involving the application of innovative remedial treatment technologies to solve site contamination and waste management problems for a UK client. The company has been appointed by a major retail developer to undertake remedial treatment of oil and solvent contaminated soils and groundwater at a former engineering site in southeast England. The works involve the use of costeffective and innovative in situ treatment technology to reduce concentrations to safe levels, avoiding the need for the mass excavation and disposal of

Generon set a record for sales of its nitrogen generating hollow fibre membrane modules and systems to the people’s Republic of China (PRC) during the first quarter of 1995. Generon received orders that equate to approximately 42 000 standard cubic feet per hour of 99% nitrogen generating capacity during the first three months of 1995. This is more volume than has ever been sold by Generon to the PRC in a single year. The resolution of trade disputes between the US and China was viewed most 362

In order to prevent holdups to the construction contract, the remedial system is being installed as building proceeds on the site, and will be operated by Celtic over a four month period. The treatment strategy involves the use of a combined system of in-situ enhanced bioremediation, vacuum extraction, vapour control and oil/water separation. The technology has previously been applied by Celtic elsewhere in the UK, and has been successfully used to treat oil hydrocarbons, solvents and other organic contaminants.

In total the system will connect to 25 hose connection points within the designated areas; it is designed to be operated either by two operators using 50 mm bore hoses and tools, or alternatively by a single operator using a single 80 mm bore hose when bulk Droduct removal is reauired.
Dust Extraction (International) Ltd, the Leeds, UKbased manufacturer of dust extraction and central&d vacuum cleaning plant., has recently secured a second order for equipment to serve a new wood micronisation plant which is being built to serve a Dutch power station. This second order comes on top of an initial order worth 2130 000 which was for the supply of six large CV pulse-jet filter units. The new order is worth 522 750, and is for the supply of component parts for a centralised vacuum cleaning and bulk removal system. The sys-

The Seattle Water Department is considering building a filtration plant for its major supply, the Cedar River watershed, to remove a microbe. The plant would cost between $250 and $400 million. The Cedar River plant would filter 250 to 360 million gallons per day. An even larger plant would be needed if the city builds a 30 mile intertie with Tacoma to the south and brings in unfiltered water from there. Plans already are under way to build a $90 million, 120 million gallons/day filtra-

Car manufacturer Nissan is using an Eriez eddy current separator (ECS) to recover aluminium from foundry sand at its Sunderland, UK plant. The foundry sand is of a particle size range between 0.25 and 150 mm. The aluminium content varies between 1% and 2% by weight, and is generally between 5 and 50 mm in size. The contaminated sand is fed over the ECS. Aluminium recoveries are > 97% with sand loss in the aluminium of up to 8%.

The Ford Motor Company’s engine plant at Bridgend, Mid Glamorgan, UK is using Hayward automatic strainers to remove coarse contamination before fine filtration of the synthetic esther based cutting fluids. The centralised coolant systems serving the diesel connecting rod machining area at Bridgend use backflushed, rotating drum filters to achieve a nominal 200 pm particle retention. Secondary in-line hydrocyclones on grinding systems and local cartridge filters on drilling, boring and (to a lesser extent) water-based honing systems, improve filtration levels to around 80 pm. To minimise the risk of damage to the primary rotating drum filter, Ford carried out a trial using a Hayward model 595, 8-inch in-line automatic strainer on one of the centralised systems supplying coolant to an ‘Excello’ transfer machine. The trial strainer, fitted with a 150 pm strainer drum, reduced the contamination on

the clean side to 10 mg/l with a maximum particle siie of 50 Frn. As a result of the trial, a further four Hayward model 595 automatic strainers were fitted to the main centralised grinding system which supplies five horizontal, side-face grinding machinesInitial operating problems were limited to jamming of the self-cleaning mechanism by large pieces of fabrication debris and frequent shearpin replacement. These problems were solved by preventing very large debris reaching the strainers and the use of steel (rather than brass) shearpins. Once these two problems had been eliminated, the additional Hayward strainers eliminated the risk of the hydrocyclones becoming blocked and extended the life of the local in-line cartridge filters.
