Abstract: Five mechanical solid-liquid manure separators manufactured by three different
companies and located on four production dairy farms in New York State were sampled monthly from
May 2001 to December 2004 (not every separator was sampled continuously throughout this period).
Samples were analyzed in an EPA approved commercial laboratory for total solids, total volatile
solids, total phosphorus, ortho phosphorus, total Kjeldahl nitrogen, ammonia nitrogen, and
potassium. Organic nitrogen was determined by subtraction. The efficiency of capture of each
effluent stream was calculated for each constituent analyzed. All separators, regardless of farm
specific affects on separation performance, captured no more than 25 percent of the nitrogen and
phosphorus in the solid effluent stream. Implications on each farm’s CAFO plan were analyzed and
the results are presented.

Anaerobic digestion, solid-liquid separation, and drying of dairy manure: Measuring constituents and modeling emission
TL;DR: In this paper, anaerobic digestion (AD) and solid-liquid separation (SLS) can increase operational flexibility at livestock facilities, but they can also affect environmental impacts during downstream manure handling.

TL;DR: The model of roller press used in this study had the advantages of almost reaching the recommended DM content in RMS (>34%), being flexible in terms of inputs, and producing fluffy RMS, but the poor performance of the model of screw press produced RMS unsuitable for immediate use without further processing.

New York Dairy Manure Management Greenhouse Gas Emissions and Mitigation Costs (1992-2022).
TL;DR: The objectives were to quantify the changes in WMS and associated GHG emissions over time, a methane conversion factor (MCF) derived from existing data from three covered manure storage units in New York, and the benefit and cost of installing covers and flares to destroy CH from existing storage units.

Effect of different technologies and animal manures on solid-liquid separation efficiencies
TL;DR: Dry matter concentration of the input manure was found to be the best parameter used to calculate and validate regression equations that can predict dry matter and nitrogen efficiency with relative root mean squared errors of less than 50%.

TL;DR: In this paper , the effluent streams from individual slaughtering operations were segregated based on the degree of similarity and were treated separately using a hydrasieve and an externally fed rotary drum filter.

TL;DR: In this paper, economic, nutrient, pathogen, energy production, and mass flows are analyzed for five integrated manure treatment systems in New York State. And the systems vary by 1) type of digester: fixed film, plug, or mixed, 2) type energy conversion: boiler, internal combustion, engine, or micro turbine, 3) digester feed: scraped manure from freestalls, separated tie stall manure, or manure with food waste added, and 4) farm size.
