LEADER IN CHEMICAL SPECIALTIES For Waste Water Treatment and ZLD plants

PUROSORBTM

Specific powder products and blend for adsorption on WWTP of: ✓ COD < 150 ppm; ✓ Oils; ✓ Surfactants; ✓ Organic substances.

PUR-ALLTM

Chemicals Specially formulated for WWTP to remove: ✓ Sulphate < 50 ppm; ✓ Fluoride < 4 ppm;

PUROFLOCTM

Anionic Flocculants for WWTP: ✓ Medium and Heavy TSS concentration.

PUROSMOTM

Chemicals Specially formulated to manage: ✓ Ultra Filtration Units; ✓ Reverse Osmosis Units; ✓ Evaporators Units 7

WHY TO INSTALL Z.L.D.

✓ Extremely restrictive local limits ✓ No available sewer ✓ No available water ✓ Expensive water cost

✓ 97 – 98 % Washer Water Reuse ✓ Environmentally friendly - Ethical Reasons ✓ Risk of dispute with local authorities ✓ Superior quality of reused water in comparison with Tap Water

✓ Possibility to plan installations indipendently of local legislation 8
