REUSE WATER AT PLASTIC RECYCLING PROCESS (real case study)

Unlike many other water treatment manufacturers we are not just machine builder but also big recycling company. We know what really can work in tough recycling reality. We provide affordable waste water treatment solutions for plastic recycling industry. Mechanical water filtration, chemical water treatment. We manufacturer the full range of machines. Waste water treatment plant from GRAN GARO is made for RECYCLENE plastic recycling company in Russia. The recycling company processes highly contaminated municipal waste plastics such as LDPE film, HDPE containers and bottles. Gran Garo waste water treatment solution consists of several stages of the waste water treatment: - first the water from two washing lines goes to the underfloor sand classifier where sand is extracted from the water flow - second the water is pumped onto two rotating disc screens where the small fines of plastic and paper are separated from the water through 200 microns rotating screens - after rotating discs screens the water flow goes to chemical treatment stage. Flocculants and polyelectrolytes are added into the waste water in order to obtain better clarification of the water. - the sedimented sludge is continuously removed from the conical parts of big sedimentation lamellar tank, dehydrated and disposed afterwards. The plastic recycling plant send all the water back to plastic washing process after this physical-chemical treatment, which saves costs and complies with regulatory requirements.
