 for Wastewater Plant Poultry

 Slaughterhouse CHALLENGE / OPPORTUNITY 

 A poultry slaughterhouse located in the south of Brazil, with a

slaughter capacity of 150,000 birds per day was using 19,600

kg/month of aluminium sulphate and 12,600 kg/month of ash in the

flotation system of its WWT with satisfactory cost and performance

results. However, diluting these products (powder) and preparing

many batches per day proved difficult. Another problem caused by

the use of a metallic salt coagulant/flocculant in the flotation system

was the great variation of the pH value of the treated effluent due

to water alkalinity consumption requiring the use of alkalinizing

agents.

 After performing a series of laboratory tests, Ta n f  l  o c started

to be used in a successful attempt to improve COD, G&O and

cost reduction and optimize manpower.

Thanks to their versatility,Tanfloc products haveeffective action on severaltypes of water as well asvarious sorts of industrialeffluent. They are usuallyemployed in drinking water treatment and in the

treatment of effluents fromBENEFITS DERIVING FROM THE APPLICATION OF TANFLOC 

•  Reducing handling of 32,200 kg/month of powder chemicalproducts;

•  80,2% COD reduction;

•  88,7% G&O reduction;

•  Rationalised manpower use;

•  Generation of organic sludge for unrestricted use in farmingland;

•  Use of a biodegradable product compatible with the subsequent

secondary treatment (activated sludge);•  Operator health and safety improvement by

eliminating/reducing handling of chemical products;

•  Eliminating the use of alkalinizing agents.COST ANALYSIS 

several sectors includingthe petrochemical, ceramic,food, sugar, metal andcellulose industries, oilrefineries, mining anddomestic sewage.Tanfloc is compatible withmost products on themarket and may be used incombination with such

products.Tanfloc works with minimalinterference with theenvironment and offersvarious economicadvantages.
