Noise issues via an adjoining wall (due to poor siting of fans). Turbo cowl on stack to increase plume rise. Relocated ducting and fan (initially causing resonance in neighbouring property) partial enclosure and AV mounts. At eaves height Residential Odour Nuisance mitigated by: General Main areas of concern: Portuguese /various 2 banks ESP followed by 2 banks UV/ozone filters 1 m above eaves • Minimise odour through better cleaning of grease filters and more frequent changes of carbon filters. • Competence of installing body; • Discharge height; • Loading on filters; • External doors left open; • Sealing of gaps between buildings; and • Use of cowls. New site • Two banks of ESPs provide high degree fume control. • First bank UV system generates ozone. • Second bank destroys residual ozone. • Similar system used with absolute filters. • Bad experience with odour neutralising agents on burger bars.
Urban Kebab none At eaves height but discharging horizontally Rural Small scale Chinese Coastal/urban Various (Greek, kebab, fish & chips, Thai, Spanish, Indian and Chinese) Urban Change of use from tea room to fish and chip shop Coastal/Rural Teashop, changing to, Grease and prefilters, charcoal Discharged at eaves Shops with residential on first/second floor Beside residential property in terrace None (tea room) None (tea room) Residential area with flats over restaurant None on teashop and None on teashop, small 87 Odour/noise • EHO Noise limits set at nearest noise sensitive receptor. Odour/ Noise 5-6 different complainants • Enforcement under EPA difficult because closest location vacated. • EHO ideally seeking stack height to be raised. • Silencer installed to deal with noise. • On-going problem that started when cooking commenced • Planning conditions required: Pre-Filter change every 2 weeks. Carbon filter change every 4 to 6 months • Tonal content caused noise problems Residential Odour/noise • Found that poor maintenance made carbon filtration ineffective. • Using carbon filtration effected noise – though higher back pressure. • Chemical neutralisation system is found to be effective, but still needs maintenance. • High level discharge necessary but problems encountered with site on rising ground. Odour Old building separated in to flats. Ground floor flat granted A3 use as tea room. Changed use to fish and chip shop. Low level extract and odour neutralising system installed. Did not work. Notice served. On going problem. Council are seeking: • Stack to 3m above eaves; and • Filtration with carbon filters. Residential in Odour/noise Current tenants installed:
