Major Swedish pharmaceutical contract awarded
STRIALNEWS Contra-Shear suboscreens for Wanganui City in New Zealand
Major Swedish pharmaceutical contract awarded
Contra-Shear Engineering Ltd of Auckland, New Zealand has installed two 1.5m diameter inchannel suboscreens, for Wanganui City in mid 1993. After about 12 months of operation, at their Beach Road Plant, the Wanganui District Council are said to be very satisfied with the ongoing sucess of the underground installation. The objective of the contract was to pre-treat raw sewage, which had previously been shredded by comminutors and pumped to sea, by means of fine screening. The scope of the contract, which was won on a competitive tender basis against international bidders, was to supply install and commission fine screens, washing, dewatering and conveyancing equipment to handle initially the screenings from raw domestic sewage, industrial waste water and storm water. It should be noted that a specially designed sparging system was incorporated so that the screened filtrate, directly downstream of the suboscreen, can be recycled for re-use as sparge water. Contra-Shear believes that this leads to major savings in sparge water costs. To achieve the above objective and capture solids of 4 mm and over, Contra-Shear utilised 3 mm gap wedgewire suboscreens with integral drainer
The
screw presses. Initially the peak flow was 0.9 m3/sec/screen with an anticipated maximum suspended solids and grease loading of 2097 and 1237g/m3 respectively. The main industrial waste water discharges were from meat works, tanneries, wool scours and fish processors. The compact, headloss, inchannel fine suboscreen (lmm to 6mm gap) was said to be the ideal choice for primary screening of sewage water intakes and industrial effluents. With only the rotating stainless steel drum immersed in the effluent, a long service life assured with minimal operating or maintenance costs. Attention has also been paid to eliminating moving parts and unnecessary components so as to provide the least possible chance of fouling by effluents solids. Contra-Shear has exported its technology to over 37 countires worldwide. In the UK, it has milliscreen/suboscreen installations with North West Water, Welsh Water and Yorkshire Water Authorities. The Screens are utilized in a wide range of municipal and industrial areas. Contra-Shear, CPO Box 1611, 31 Bancroft Crescent, Glendene, Auckland 8, Nao Zealand. Tel: +6498186108, fart +649818 6599.

new laboratories of Astra H&sIe, a pharmaceutical research company based in Mclndal, Sweden, are to be equipped with 30 state-of-the-art water purification systems, developed by Elga Ltd. Negotiated by AI3 Ninolab, Elga’s Swedish distributors, the contract is said to be the largest single overseas order ever received for the company’s laboratory product range. Of the 30 water purification systems, 26 will be wallmounted and comprise an Elgastat Proma 2 reverse osmosis unit coupled with an intermediate tank and an Elgastat Maxima multiple-technology unit. Three further Maxima units will be incorporated into existing ring-main systems. Two versions of the Elgastat Maxima will be supplied, both utilising ion-exchange, organic adsorption and UV photo-oxidation. In addition, the Analytical model of the Maxima features- an ultramicrofilter, and the Life Science model an ultrafilter. Continuous recirculation of water from the Maxima units back to the tank ensures an
instantaneous supply of ultrapure water and prevents an excessive build-up of water temperature. Each of the other four water purification systems will consist of an Elgastat Prima 7 reverse osmosis unit, together with a recirculation tank, pump and ring-main incorporating a UV lamp and microfilters. Replacing an earlier system featuring a lengthy run of unhygienic distribution pipework, the four new ring-main systems will supply purified water to washing machines and outlet points in the laboratories. Research at Astra Hlssle, part of the multinational Astra Pharmaceuticals group, is centred on the development of drugs for treating cardiovascular and gastrointestinal disease. Primary-grade water for glassware washing and general reagent water for critical applications such as HPLC, AA spectrophotometry and tissue culture till be provided by the Maxima units.

Reverse jet filter installed in France Airmaster Engineering has carried out two installations in France, gaining the business through its German sister company, BMD. For steel castings manufacturers Hachette & Driort Si, of St. Divier, Airmaster installed a reverse jet cleaned filter. This exhausts air from a shotblasting process that removes sand and scale from the metal surfaces of castings. Airmaster specified an RJX 105/A/7-12 reverse jet filter with a capacity of 12 000 m”/h. It uses a polyester needlefelt filter material to achieve a maximum emission level of 10 mg per m3, from a dust concentration of 20 g per ms. For concrete slab manufacSeptember/October
