Orifices feed the sludge to be filtered under pressure in the filtration chamber. They are usually placed in the center of the plates allowing a proper distribution of flow, right pressure and better drainage of sludge within the chamber. Solids sludge gradually accumulates in the filtration chamber until the final compacted cake is formed.

From the aeration tank the water passes to a clarifying tank where the waste material settles out as sludge. The overflow from the clarifier is pumped through a final chlorine treatment trough and allowed to flow out to a nearby stream. BOD removal by this process is about 98% and meets regulatory standards.

During the draining phase, sludge weight and volume continue to reduce. Following two months of storage, a biosolids content of 50 percent to 90 percent dry solids can be produced. For example, 1 cubic meter of sludge at 1 percent solids content would have a solids content of 10 to 12 percent solids after a few hours of resting in the bags.

In all cases, water use, electricity use and maintenance demand should be weighed against cost and feed water suitability. Sludge dewatering further reduces water content and volume Sludge dewatering, which can occur before or after digestion, further reduces the free water content of the sludge, resulting in a solid content of between 20 and 80%.

A large volume of water may be released from the tubes during the operation and can cause erosion around the tube. As such, the rate at which the water is decanted must be monitored. The sludge dewatering tube bottom will develop a filter cake quickly, so the water will decant mainly out of the sides and top of the tube.

Sludge. Sludge is composed of dissolved solids which precipitate from produced water as its temperature and pressure change. Sludge generally consists of oily, loose material often containing silica compounds, but may also contain large amounts of barium. Dried sludge, with a low oil content, looks and feels similar to soil.
