REDUCTION OF FISHMEALS, OILS, GREASES AND PROTEINS
MANUFACTURER OF PELLETED FISH FEED - EXTRUSION PLANT

Biological Treatment Summary

The Situation

A major manufacturer of fish feed for the aquaculture industry faced numerous problems within one of their extrusion plants.

• Large volumes of organic waste and spill over from the processed fish feeds were being washed down the plants' drain line each night after the daily cleaning regiment. Organic solids and other waste were accumulating in and throughout the waste stream resulting in an overall reduction in the flow of the waste stream.
  
• Fishmeals, oils, greases and proteins were clogging the drain lines and accumulating in the septic tanks and in the basket screen.
  
• The septic tanks and basket screen required regular labor intensive clean outs. The septic tanks also required expensive pump and haul off costs every three months.
  
• The company wanted an all-natural treatment alternative that would be cost effective and allow them to manage, stabilize, and reduce the organic build up in their waste stream as well as being non-labor intensive for applications.

The Solution

Bio-Form LLC technical personnel proposed a biological treatment program that consisted of the addition of BZT® Waste Digester throughout the drain and septic system in the plant. Bio-Form LLC proposed that an initial seed application be performed followed by regular weekly maintenance applications. The treatment program was designed to reduce the overall volume of organic solids, fishmeals, oils and greases in the waste stream, and improve the flow rate in the system. Prior to the initial seed application, the company pumped out and cleaned the entire basket screen and septic system under Bio-Form LLC's general guidelines and suggestions for a successful biological treatment program utilizing BZT® Waste Digester.

The Result

The BZT® Waste Digester provided a safe and easy method for maintenance applications. Maintenance applications in the plant were conducted each night at the end of the final cleaning process. Applications only required pouring the mix directly into the plants' main drain line, which in turn, treated the whole system and allowed for non-labor intensive applications. The lateral line and drain field improved within one week after initial application and alleviated the need and cost to dig out the entire drain field and manually clean and replace the piping assemblies. This achievement alone saved the company thousands of dollars for the cost to revamp the drain field.
