Polyethylene septic tank<\/strong> for the primary treatment of wastewater<\/strong> similar to domestic, by anaerobic processes. In the absence of oxygen, anaerobic bacteria settle and digest the organic matter, gasifying, hydrolysing and mineralising it, achieving 70\u201385 % removal of organic matter.<\/p>\n

Operation:<\/strong> the septic tank pre-treats the water before a biological treatment or its discharge. It consists of chambers for the settling and anaerobic digestion of sludge and floating matter.<\/p>\n

Design:<\/strong> polyethylene tank produced by rotational moulding, resistance class 1d according to NF P16-500-1\/CN. PVC inlet and outlet connections and a \u00d8 620 mm threaded PE inspection cover. The treatment complies with Spanish discharge regulations (Water Act, RD 509\/1996) and the conformity under Annex ZA of EN 12566-1.<\/p>\n

Advantages:<\/strong> linear polyethylene with anti-UV additive, easy installation, with horizontal and vertical reinforcements for greater resistance to ground pressure.<\/p>\n

Maintenance:<\/strong> emptying and cleaning must be carried out once a year by an authorised operator (removal of sludge and floating matter from the settler-digester); afterwards, fill the unit with clean water.<\/p>\n

Options:<\/strong> level indicator.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
