The composition and strength of wastewater from slaughterhouses creates many treatment and discharge challenges for these facilities. It has high volumes of hard-to-filter components such as blood, dirt, manure and fat, oil and grease (FOG).

The Salsnes Filter system can separate these components because of the design of the filtermesh. First, fiber and grain from manure are collected on the filtermesh. These larger particles begin to collect smaller particles to create a “filter mat”. Separation performance is enhanced as particles continue to build-up on the filter mat, creating progressively smaller holes that retain increasingly smaller particles.

At fish hatcheries and farms, solids can develop in the water from fish waste and uneaten food. In high amounts, these solids negatively impact the growth and survival rates of the fish because they demand oxygen and contaminate the water with ammonia. A Salsnes Filter system can effectively remove these solids (without crushing like a typical drum filter) to maintain a high water quality for the fish.

Sea lice are naturally occurring, minute parasites that attach themselves to the skins, fins and gills of fish. Infestation can occur anywhere; along coastlines, around fish farms, in vessels transporting live fish and at fish slaughterhouses. The most commonly used treatment methods only temporarily paralyze the sea lice, thereby allowing future infestations.

A Salsnes Filter system separates the sea lice (and their eggs) from the water to be properly disposed of. The almost 100% reduction in sea lice improves water recirculation, resulting in higher fish survival rates, and contributing to lower operational costs.
