This job i refeer to is for containment of WWTP odours from primary settlement tanks and influent and outlet effluent. The following questions require answering: The technology proposed, The cover type and all materials of construction, Corrosion resistance to H2S and WWTP odour for all materials of construction, The leakage rate per unit area (%/m2) The loadbearing weight per m2 The cost to cover 7000 m2 in total, The area to be covered is split into two large areas spanning 2X 40 metresX73 metres and remaining option 2 area with a span from 3 m to 6 metres wide. The covers must be low profile. Color of material (RAL number). Details on access hatched, Details on removing covers to perform mantainence, Details on maintenance and how often and what protocols of mantainence should be implemented, Issues with birds on cover, Recommended air removal rate per hr to maintain negative ventilation under the cover and therefore prevent the leakage of odour due to wind and thermal pressure. Assume 5 m/s as air flow rate average and 12 m/s maximum. Temperature from 2 degrees to 37 degrees centrigrade. If alumina supports are proposed please outline the coating materials to be used to prevent corrosion of the alumina supports with salts and acids. The lifetime of the cover assuming H2S conc of 50, 100, to 150 ppm under the cover. Previous installations. Condensation/drip points details, Any other issues you percieve been a problem. If you require any further details please do not hesitate to contact me. I need a fast response to this as this will go for tender soon. I need to know if your company has the capabilities to perform such a task.
