WWTPi Meat Sector (pig slaughterhouse)

Netwater Technology, has carried out the complete installation of a Fine Sieve for the retention and extraction of (guts, pieces of meat, fats) which are discharged into an auger conveyor that transports them to a container for one of the most important companies in the pig sector in slaughterhouse:

• A FineTech®Nw60 fine screen, to treat a Q=300m3/h, working inclination at 75º, 6mm pitch, main material of construction in AISI-316L.
• A ScrewTech®Nw80.180 screw conveyor, for conveying Q=1m3/h, with a 15º inclination, main material of construction in AISI-316L.
• An electrical panel to control the screen and auger, to preserve the main geared motors, we have installed M20 torque limiters for the screen and auger.
• To be installed in an existing civil work channel, where they had installed a MEVA or ABS type stair screen, which had never worked before.

The main objective of our client was to install a type of sieve, which would work optimally and would be capable of (retaining, extracting and transporting waste in a container), he requested that the auger be elevated and fixed to the lower part of the existing structure, thus leaving the passage area free for maintenance personnel, minimising the risk of accidents or falls:

– At present they had a ladder type screen, which was not capable of transporting the waste to the discharge area (this is a type of technology that works by means of an elliptical movement made up of a fixed and a mobile mesh, which are always submerged and difficult to access for cleaning), This means that they become impregnated with grease and prevent the waste from being lifted and sliding to the bottom of the channel, the sieve collapsed and the water and waste ended up overflowing and this waste caused serious blockages and continuous breakdowns in the pumps, in very cold weather, the grease solidifies, producing greater resistance in the elliptical movement, causing the main motor to break.

– By installing our FineTech® Nw60 fine screen + ScrewTech® Nw80.180 screw conveyor, the new screen is capable of “retaining, elevating and discharging” (casings, large pieces of fat, meat, skins), which are contained in the filtered water coming from your production processes.) This saves on repairs to existing pumps and allows them to continuously pump the water to the next screening system consisting of a Rotary sieve.
