Smith Petrie, a specialist in the manufacture of wool processing effluent systems, now owns the marketing rights to a new low pollution proofing process for carpet wool. The new process, Enviro-Proof, dramatically reduces the permethrin content of mill effluent discharges. The International Wool Secretariat developed the process at S. Lyles Sons && Company Limited of Dewsbury. The system uses a low volume continuous application bowl placed at the end of a tape or brattice scour. The use of process control and chemical metering equipment minimizes the pollutant load normally associated with this method of mothproofing. Effluent load reductions of 90 percent are possible. The storage of process liquor between batches is feasible, allowing reuse for subsequent yarn batches and providing an overall effluent pollutant reduction of 99 percent.
