This sludge ferments, gives off odours and maintains an excess of organic matter. Bactovase is based on biofixation: natural, non-pathogenic micro-organisms are fixed onto mineral carriers, together with enzymes and trace elements. The insoluble powder sinks and settles on the surface of the sludge, where the bacteria break down its organic fraction into CO₂ and water. Unlike dredging, the sludge is not moved elsewhere: it is broken down where it lies.\u003c\/p\u003e\n\u003csvg viewBox=\"0 0 480 270\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" role=\"img\" aria-label=\"Cross-section diagram: before treatment, a thick layer of organic sludge on the pond bottom; after treatment, a reduced sludge layer and clearer water\"\u003e\u003ctext x=\"118\" y=\"22\" text-anchor=\"middle\" font-size=\"17\" font-weight=\"700\" fill=\"#273a48\"\u003eBefore\u003c\/text\u003e\u003ctext x=\"362\" y=\"22\" text-anchor=\"middle\" font-size=\"17\" font-weight=\"700\" fill=\"#273a48\"\u003eAfter treatment\u003c\/text\u003e\u003cpath d=\"M10 40H226V205Q118 235 10 205Z\" fill=\"#b9d3a8\"\/\u003e\u003cpath d=\"M10 130Q60 120 118 128Q175 136 226 124V205Q118 235 10 205Z\" fill=\"#6b4f2e\"\/\u003e\u003cg fill=\"#cfe6ef\" opacity=\".8\"\u003e\u003ccircle cx=\"50\" cy=\"112\" r=\"4\"\/\u003e\u003ccircle cx=\"56\" cy=\"92\" r=\"3\"\/\u003e\u003ccircle cx=\"150\" cy=\"114\" r=\"4\"\/\u003e\u003ccircle cx=\"144\" cy=\"94\" r=\"3\"\/\u003e\u003ccircle cx=\"196\" cy=\"108\" r=\"3.5\"\/\u003e\u003c\/g\u003e\u003ctext x=\"118\" y=\"178\" text-anchor=\"middle\" font-size=\"16\" font-weight=\"700\" fill=\"#fff\"\u003eThick sludge\u003c\/text\u003e\u003ctext x=\"118\" y=\"250\" text-anchor=\"middle\" font-size=\"15\" fill=\"#5f6b72\"\u003eFermentation, odours\u003c\/text\u003e\u003cpath d=\"M254 40H470V205Q362 235 254 205Z\" fill=\"#cfe6ef\"\/\u003e\u003cpath d=\"M254 182Q314 176 362 180Q414 186 470 178V205Q362 235 254 205Z\" fill=\"#6b4f2e\"\/\u003e\u003cg fill=\"#88be22\"\u003e\u003ccircle cx=\"275\" cy=\"180\" r=\"3.5\"\/\u003e\u003ccircle cx=\"300\" cy=\"178\" r=\"3.5\"\/\u003e\u003ccircle cx=\"330\" cy=\"177\" r=\"3.5\"\/\u003e\u003ccircle cx=\"362\" cy=\"179\" r=\"3.5\"\/\u003e\u003ccircle cx=\"395\" cy=\"181\" r=\"3.5\"\/\u003e\u003ccircle cx=\"425\" cy=\"180\" r=\"3.5\"\/\u003e\u003ccircle cx=\"452\" cy=\"178\" r=\"3.5\"\/\u003e\u003c\/g\u003e\u003cg fill=\"#e07b2a\"\u003e\u003cpath d=\"M330 100q18-12 34 0q-16 12-34 0Z\"\/\u003e\u003cpath d=\"M364 100l9-7v14Z\"\/\u003e\u003c\/g\u003e\u003ctext x=\"362\" y=\"160\" text-anchor=\"middle\" font-size=\"16\" font-weight=\"700\" fill=\"#273a48\"\u003eReduced sludge\u003c\/text\u003e\u003ctext x=\"362\" y=\"250\" text-anchor=\"middle\" font-size=\"15\" fill=\"#5f6b72\"\u003eOrganic matter broken down\u003c\/text\u003e\u003cpath d=\"M232 120H248\" stroke=\"#273a48\" stroke-width=\"2.5\"\/\u003e\u003cpath d=\"M242 113L250 120L242 127\" fill=\"none\" stroke=\"#273a48\" stroke-width=\"2.5\"\/\u003e\u003c\/svg\u003e\n\u003cp class=\"note\"\u003eIllustrative diagram, not to scale.
