Hydroair has executed several ETPs for industries like dairies, distilleries, breweries, sugar and textile mills. The high organic content of these effluents has encouraged anaerobic systems to be implemented, generating biogas which may be used as a supplementary fuel. For water intensive industries like dairies and distilleries water recycle& reuse is also implemented. Hydroair has several installations for cooperative dairies under National Dairy Development Board and also for text ile units under National Textile Corporation.
Hydroair also has experience in oil producing, electroplating and other metal finishing industries.
