Phase I – Mechanical solids separator
A pump drives the slurry to a chamber with a flow rate adjuster that operates depending on the density of the slurry to be treated, making it possible to treat very dense and very liquid slurry in the same equipment, without the need for pre-filtering ramps to concentrate liquid slurry with low quantities of solids. This reception chamber is fitted with an exclusive patented unwanted plastic and solid retention system, meaning there is no need to fit grinder pumps, thereby generating high quality compost that does not contaminate the ground with plastics from ear-tags, catheters, etc. The slurry then passes through a unique, innovative and patented double press and scraping sieve system with round holes that filter out animal hair. The pressing and scraping system (with no need to add water to prevent the sieve from getting clogged) is adjustable, and made of plastic, so there is very little friction against metal parts, thus ensuring high durability and low maintenance and energy consumption. An electronic flow meter can be installed to record the volume of treated slurry. The separation of the solid reduces up to a 20% de volume of the solid part and reduces up to a 20% of the nitrogen and a 50% of the phosphor, improving its N-P-K balance. The solid part is easily compostable, transportable and has high value.
Phase II – Physical-chemical Reactor
Following the mechanical filtration in Tecnapur phase I, which permits up to 40% of solids to be extracted from the slurry, suspended solid particles still remain in the liquid part, most of them with a size of less than 50 microns, which are impossible to separate mechanically. They can be extracted with the physical-chemical treatment (Phase II), reducing nitrogen by up to 75% and phosphorus by up to 95% in the liquid part with respect to the initial slurry, which makes it ideal for fertigation, since it contains no suspended solids and its N-P-K balance is improved. The Tecnapur physical-chemical treatment system operates inside a reactor installed after the mechanical separator. It has a first coagulation chamber with fast agitation. The separated liquid enters this chamber where it is acidified and the chemical coagulants are added. Then the flocculation phase takes place in a second chamber, with slow agitation. Lastly, the system has a slowing-down chamber that improves the grouping and compacting of the solids, so that the filtration sieve can separate the flocculated solid. The system performs the separation at an acid pH, thus permitting the nitrogen to be maintained in the form of an ammonia ion, preventing the waste of fertiliser and the emission of ammonia gas into the air. All the above results in an improved use of space, fewer chemicals and a low power consumption.
