Reduction ghd


Has been a leader in environmental engineering for over 17 years, providing reliable, proven solutions for farmers.
The digester effluent is pumped from the bon cadeau ikea canada effluent pit at the end of the AD vessel to a manure solids separator.
GHD's anaerobic digester can handle various animal waste streams, including waste from dairy, swine, and poultry operations.
The waste heat, gagner vacances aout 2018 in the form of hot water, is collected natural cortisol reduction from both the engine jacket liquid cooling system and from the engine exhaust (air) system.The separated solids, having the same odor and pathogen reduction characteristics as the liquid stream, may be utilized by the farm for bedding replacement (an expense reduction).The residual 40 to 60 of non-utilized separated solids may be sold (system-generated income) to other farms for bedding purposes or sold to after-markets, such as nurseries and composters, for soil amendment material.Our systems greatly reduce the odor on farms, are cost- effective, operate automatically and require low maintenance.The system can be implemented at agri-businesses with organic wastes such as meat packing plants, dairy plants, and vegetable processors as well as municipal sewage treatment plants and other waste treatment facilities.Approximately 30 to 60 of this waste heat is utilized in the AD system.Other types of organic wastes can be digested in GHD's digester, such as fats, oils, sugars, starches, etc.Use of the separated solids for bedding typically comprises about 40 to 60 of the generated separated solids from a typical farm.Advantages of a GHD digester include: - Efficient electricity generation - Quality bedding without composting - Excess heat for farm use - Odor reduction - Increased fertilizer value - Pathogen reduction - Weed seed reduction - Low maintenance - Proven technology - Low operation costs.The liquid from the manure separator, now with the majority of the large solids removed, gravity flows into the farms storage lagoon.Our digesters are designed to be operated by the farmer, are simple to maintain and, above all, are optimized for on-farm reliability.The patented two-stage digester converts manure and other organic wastes into three valuable byproducts: a biogas, which can be burned in a genset to create electricity or scrubbed to make natural gas; a biosolid, used as a high-quality bedding for cows or as a soil.These gensets are commercially available, natural gas-fueled reciprocating engines modified to burn biogas.The electricity produced by these gensets can be used to offset on-farm power consumption; excess power can be sold directly to the utility as a source of green power.Leader in anaerobic digestion, GHD's patented two-stage mixed plug-flow digesters process more farm waste than any other with unparalled performance. .Unique to our industry, every GHD digester installed is still in operation today.A large advantage of the effluent from the AD treatment process is that the viscosity of the effluent is such, as opposed to the raw manure influent, that the liquid effluent can be pumped through an irrigation nozzle for field spreading.The mechanical manure separator separates the influent digested waste stream into solid and liquid fractions.The remaining waste heat can be used by the farm as a replacement for hot water production (reducing the need for natural gas or propane purchases) and for in-floor heating of the farm and holding areas, as required.

The solids are dewatered to approximately a 35 solid material.
